How to Create a Modal Popup with a Fade and Slide Effect

Modals are a great way to grab attention and present information without leaving the current page. In this tutorial, we’ll learn how to create a stylish modal popup that fades in and slides down from the top using HTML, CSS, and JavaScript.

Step 1: HTML Structure

Start by creating the basic structure of the modal:

    

        ×
        
Modal Title
        
This is a modal popup with a fade and slide effect!
    

• The 'button' element triggers the modal.
• The 'div' with the'modal' class serves as the overlay.
• The 'div' with the 'modal-content' class contains the modal’s content.

Step 2: CSS Styling

Use CSS for styling and animation:

body {
    font-family: Arial, sans-serif;
}

button {
    margin: 20px;
    padding: 10px 20px;
    font-size: 16px;
    cursor: pointer;
}

.modal {
    display: none;
    position: fixed;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background: rgba(0, 0, 0, 0.5);
    justify-content: center;
    align-items: flex-start;
    animation: fadeIn 0.3s ease-out;
}

.modal-content {
    margin: 100px auto;
    background: #fff;
    padding: 20px;
    border-radius: 8px;
    box-shadow: 0 5px 15px rgba(0, 0, 0, 0.3);
    width: 80%;
    max-width: 500px;
    animation: slideDown 0.5s ease-out;
}

.close {
    position: absolute;
    top: 10px;
    right: 20px;
    font-size: 24px;
    cursor: pointer;
}

@keyframes fadeIn {
    from {
        background: rgba(0, 0, 0, 0);
    }
    to {
        background: rgba(0, 0, 0, 0.5);
    }
}

@keyframes slideDown {
    from {
        transform: translateY(-50px);
        opacity: 0;
    }
    to {
        transform: translateY(0);
        opacity: 1;
    }
}

Step 3: JavaScript for Interaction

Now, add JavaScript to handle the modal’s behavior:

document.getElementById('openModal').addEventListener('click', function () {
    const modal = document.getElementById('modal');
    modal.style.display = 'flex';
});

document.getElementById('closeModal').addEventListener('click', function () {
    const modal = document.getElementById('modal');
    modal.style.display = 'none';
});

window.addEventListener('click', function (e) {
    const modal = document.getElementById('modal');
    if (e.target === modal) {
        modal.style.display = 'none';
    }
});

This script ensures that:

• Clicking the "Open Modal" button shows the modal.
• Clicking the close button or outside the modal content hides it.

Live Demo

Combine the HTML, CSS, and JavaScript, and you'll have a working modal popup with a beautiful fade and slide effect.

Final Thoughts

Modals are versatile and enhance user engagement. This tutorial showcases a simple yet effective way to implement a fade and slide effect for your modal popup. Customize the styles and animations to suit your design preferences.

How to Use the WordPress Video Shortcode

WordPress makes it incredibly easy to embed videos directly into your posts or pages using its built-in [video] shortcode. Whether you’re hosting the video yourself or using an external URL, the shortcode provides a clean and customizable way to showcase videos on your site.

Basic Usage

Here’s the simplest way to use the video shortcode:

[video src="https://example.com/wp-content/uploads/video.mp4"][/video]

This will embed a video with the provided URL.

Adding Multiple Sources

For better browser compatibility, you can provide multiple video sources:

[video]
    [source src="https://example.com/video.mp4" type="video/mp4"]
    [source src="https://example.com/video.ogg" type="video/ogg"]
    [source src="https://example.com/video.webm" type="video/webm"]
[/video]

This ensures your video can play on different browsers that may support varying file formats.

Attributes for Customization

The [video] shortcode supports several attributes:

1. src: The source URL of the video (required if no inner sources are provided).

2. poster: The URL of an image to display before the video starts.

3. width: Sets the width of the video.

4. height: Sets the height of the video.

5. loop: Makes the video play in a loop.

6. autoplay: Starts the video automatically when the page loads.

7. preload: Defines how the video should be loaded. Options are:

   • auto: Load the entire video.

   • metadata: Load only metadata.

   • none: Do not preload.

Example with customization:

[video src="https://example.com/wp-content/uploads/video.mp4" poster="https://example.com/poster.jpg" width="640" height="360" autoplay="true" loop="true"][/video]

Adding Poster Images

Poster images are crucial for enhancing the visual appeal of your video embeds. They act as placeholders before the video is played.

Here’s how you can include a poster image:

[video src="https://example.com/video.mp4" poster="https://example.com/poster.jpg"][/video]

This will display the image located at https://example.com/poster.jpg before the video starts playing.

Self-Hosted vs. External Videos

• Self-hosted videos: Upload your video to the WordPress Media Library and use its URL in the shortcode.
• External videos: WordPress supports embedding external video URLs (e.g., YouTube or Vimeo) directly by pasting the link in the editor without the need for a shortcode.

Shortcode with Captions

You can add captions to your video by wrapping the shortcode inside the [caption] shortcode:

[caption id="" align="alignnone" width=""]
    [video src="https://example.com/wp-content/uploads/video.mp4"][/video]
    
Caption text goes here.
[/caption]

Advantages of Using Shortcodes

• Flexibility: Easily embed and configure videos.
• Compatibility: Works across all modern browsers.
• Ease of Use: No need for complex HTML or external plugins for basic functionality.

Best Practices

• Optimize videos: Compress your videos to reduce load time and improve user experience.
• Use poster images: Add a placeholder image for a professional look.
• Avoid autoplay: Not all users appreciate videos that start automatically.

Conclusion

The WordPress video shortcode is a powerful tool for embedding videos seamlessly into your site. By leveraging its attributes and options, you can create a polished and engaging video experience for your audience.

Ten Strange Things in Technologies

Technology is evolving at a breakneck speed, and with that comes innovations that often feel too strange to be true. From quantum computing to self-healing materials, the world of tech is full of surprises. Let’s dive deeper into ten of the most fascinating and bizarre advancements that are changing the way we live, work, and even think.

1. Quantum Computing’s Superposition Magic

Quantum computing takes a radically different approach to computation compared to traditional computers. While classical computers process information in binary (0s and 1s), quantum computers use qubits. These qubits can exist in a state of both 0 and 1 simultaneously due to a phenomenon called superposition. This ability allows quantum computers to perform complex calculations exponentially faster than classical computers. While still in its infancy, this technology has the potential to revolutionize fields such as cryptography, medicine, and artificial intelligence. But the concept of quantum mechanics itself — where particles can exist in multiple states — can be baffling to our everyday understanding of the world.

2. AI’s Creativity

Artificial intelligence has made tremendous strides in the creative domain. AI is now capable of producing art, music, and even written content that can rival human creations. Tools like OpenAI’s GPT-3 and DALL-E generate text and images that seem indistinguishable from those created by humans. While it may seem strange that a machine can be "creative," this phenomenon is reshaping industries ranging from design to entertainment. AI’s creativity challenges traditional ideas about what it means to be an artist or creator, raising questions about originality, authorship, and the role of machines in the creative process.

3. Digital Twin Technology

Imagine having a virtual copy of yourself or your home. Digital twin technology makes this a reality by creating digital replicas of physical objects, systems, or even entire cities. These digital models simulate real-world behavior and can be used for testing, monitoring, and optimizing performance. For instance, in smart cities, digital twins can predict traffic patterns or energy usage. In healthcare, they can simulate organ functions for personalized treatment plans. The concept of living in a digital replica of the real world might sound like science fiction, but it’s already happening.

4. Self-Healing Materials

Self-healing materials have been designed to repair themselves when damaged, mimicking the regenerative capabilities found in nature. These materials are used in various industries, from aerospace to construction. For example, concrete can now "heal" cracks with the help of bacteria that produce limestone when exposed to air. This technology has enormous potential, reducing maintenance costs and extending the lifespan of structures. In the future, we may have clothing, electronics, and even human skin that can repair themselves.

5. Internet via Balloons and Drones

Accessing the internet in remote areas has always been a challenge. However, companies like Google’s Project Loon have developed innovative solutions. By deploying high-altitude balloons or drones equipped with internet-transmitting technology, these projects aim to provide global connectivity, especially in underserved regions. The idea of floating balloons providing internet access to entire communities sounds almost absurd, but it’s a viable solution that is gradually making its way into the real world.

6. Brain-Computer Interfaces (BCIs)

Brain-computer interfaces (BCIs) are another mind-boggling technological advancement. These devices establish a direct link between the human brain and computers, enabling users to control devices with their thoughts. Companies like Neuralink are working on BCIs that could eventually help those with physical disabilities regain control of their limbs or even improve cognitive abilities. While the idea of machines reading our minds sounds like something out of a dystopian novel, BCIs are already showing potential in medicine and neuroscience. The ethical concerns surrounding privacy and control, however, are significant and need careful consideration.

7. Haptic Feedback Suits

Virtual reality (VR) is already an immersive experience, but haptic feedback suits take immersion to the next level. These wearable devices allow users to feel sensations in a virtual environment, such as the texture of objects or the force of a virtual punch. Whether for gaming, training simulations, or medical rehabilitation, haptic technology brings a new dimension to virtual experiences. The idea of "feeling" a virtual world that isn’t physically there can be both thrilling and unsettling, but it’s one of the most advanced ways we interact with digital environments.

8. Biohacking

Biohacking, or the DIY biology movement, has led to some bizarre and intriguing modifications to the human body. People are implanting technologies such as RFID chips or magnets beneath their skin to enhance their abilities or gain new features. Some biohackers even experiment with gene editing techniques like CRISPR to modify their DNA. While this might seem like something out of a futuristic sci-fi film, biohacking is very much real and raises important ethical questions about the limits of human enhancement.

9. Space Mining

The idea of mining asteroids for resources is no longer the stuff of science fiction. Space companies like Planetary Resources and Deep Space Industries are exploring ways to extract valuable materials from asteroids, such as water, platinum, and rare metals. With the potential to tap into resources that are rare or nonexistent on Earth, space mining could radically change the global economy. The technology to mine asteroids is still in development, but the fact that we are even considering this as a possibility shows just how strange and exciting the future of technology can be.

10. Hyper-Realistic Deepfakes

Deepfakes are AI-generated videos that can manipulate footage to make people appear as though they are doing or saying things they never actually did. The technology uses deep learning algorithms to create hyper-realistic fake content, and its applications range from entertainment to political manipulation. While deepfakes can be a fun tool for creating realistic special effects or entertainment, they pose serious risks to privacy, security, and trust. The ability to create convincing fake videos with just a few clicks is unsettling, and it raises ethical concerns about the power of AI to deceive and mislead.

These ten strange technologies represent just a glimpse of what’s on the horizon. While they may seem bizarre or even unbelievable, many are already shaping the world in profound ways. As technology continues to evolve, we can expect even more astonishing advancements that challenge our understanding of what is possible. The future is stranger than we can imagine, but it’s also full of exciting potential.

How to Update Image Alt Attributes Programmatically in WordPress

Alt attributes play a crucial role in enhancing your website's accessibility and SEO. However, manually updating the alt text for every image in your WordPress media library can be time-consuming, especially for larger sites. In this tutorial, I'll show you how to programmatically update image alt attributes in WordPress.

Why Update Alt Attributes Programmatically?

• Improved Accessibility: Alt text helps screen readers describe images to visually impaired users.
• Better SEO: Search engines use alt text to understand image context, improving your site’s rankings.
• Time-Saving: Automating alt updates eliminates manual effort.

The Code: Adding or Updating Alt Text Programmatically

To update image alt text, you can add the following snippet to your theme’s functions.php file or a custom plugin:

function update_image_alt_texts() {
    // Fetch all media attachments
    $args = array(
        'post_type'      => 'attachment',
        'post_mime_type' => 'image',
        'posts_per_page' => -1,
    );

    $attachments = get_posts($args);

    foreach ($attachments as $attachment) {
        $alt_text = get_post_meta($attachment->ID, '_wp_attachment_image_alt', true);

        // Check if alt text exists
        if (empty($alt_text)) {
            // Generate alt text based on image title
            $custom_alt_text = get_the_title($attachment->ID);

            // Update the alt attribute
            update_post_meta($attachment->ID, '_wp_attachment_image_alt', $custom_alt_text);
        }
    }
}
add_action('init', 'update_image_alt_texts');

How It Works:

1. Retrieve Images: The get_posts function fetches all images from your media library.
2. Check Existing Alt Text: The get_post_meta function checks if the alt attribute is empty.
3. Set New Alt Text: If empty, a new alt text is generated using the image title and updated with update_post_meta.

Tips for Implementation

1. Test in Staging: Always test your code in a staging environment before applying it to your live site.
2. Backup Data: Create a backup of your database to prevent data loss.
3. Run Once: Remove the function after running it to avoid redundant executions.

Final Thoughts

Automating the process of adding meaningful alt text to your images is a great way to enhance your site's user experience and SEO. By leveraging the above script, you can save hours of manual work and ensure that your website is accessible to all users.

Integrating Static Forms in Dynamic Popups: A Step-by-Step Guide

Dynamic popups are a powerful tool for enhancing user interaction on websites, allowing you to display content or forms without reloading the page. Integrating static forms into these popups can provide users with a seamless experience, whether for login, registration, or data collection purposes. Here’s a step-by-step guide to achieve this integration effectively.

Step 1: Prepare Your Static Form

Start by creating the HTML for your static form. This form will later be embedded into the popup.

Example:

    

        Name:
        

        Email:
        

        
    

Step 2: Design the Popup Structure

Define a container for the popup with an overlay for better visibility. The popup will dynamically display the static form.

Example:

    ×
    

        
    

Step 3: Add Styling for the Popup

Ensure the popup is visually appealing and centers on the screen. Use CSS for styling.

Example:

#popup-overlay {
    position: fixed;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background: rgba(0, 0, 0, 0.7);
    z-index: 999;
}

#popup {
    position: fixed;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    background: #fff;
    padding: 20px;
    border-radius: 5px;
    box-shadow: 0 4px 10px rgba(0, 0, 0, 0.3);
    z-index: 1000;
}

#close-popup {
    position: absolute;
    top: 10px;
    right: 10px;
    cursor: pointer;
}

Step 4: Write JavaScript to Display the Popup

Use JavaScript to dynamically insert the form into the popup and display it when a button is clicked.

Example:

// Show popup
function showPopup() {
    const form = document.getElementById('static-form').innerHTML;
    document.getElementById('popup-content').innerHTML = form;
    document.getElementById('popup-overlay').style.display = 'block';
    document.getElementById('popup').style.display = 'block';
}

// Hide popup
function hidePopup() {
    document.getElementById('popup-overlay').style.display = 'none';
    document.getElementById('popup').style.display = 'none';
}

// Event listeners
document.getElementById('open-popup-button').addEventListener('click', showPopup);
document.getElementById('close-popup').addEventListener('click', hidePopup);
document.getElementById('popup-overlay').addEventListener('click', hidePopup);

Add a button to trigger the popup:

Step 5: Handle Form Submission

Ensure that the form submission works seamlessly within the popup. Use AJAX to submit the form data without refreshing the page.

Example:

document.addEventListener('submit', function (event) {
    if (event.target.id === 'contact-form') {
        event.preventDefault();

        const formData = new FormData(event.target);
        fetch('submit-form.php', {
            method: 'POST',
            body: formData,
        })
        .then(response => response.json())
        .then(data => {
            alert(data.message);
            hidePopup();
        })
        .catch(error => {
            console.error('Error:', error);
        });
    }
});

Step 6: Test Your Implementation

• Verify that the popup displays correctly on all devices.
• Ensure that the form submission works as expected.
• Check for accessibility and usability improvements, such as keyboard navigation and focus management.

Result

Integrating static forms into dynamic popups can enhance user engagement on your website. By following this guide, you can implement this feature securely and efficiently, ensuring a smooth experience for your users. Experiment with styling and functionality to match your project’s requirements.

Top 5 Mistakes Developers Make When Working with PHP Forms

PHP forms are an essential part of web development, enabling user interactions such as registrations, logins, and data submissions. However, developers often encounter common pitfalls that can lead to security vulnerabilities, functionality issues, or poor user experiences. In this post, we’ll explore the top 5 mistakes developers make when working with PHP forms and how to avoid them.

1. Neglecting Input Validation and Sanitization

One of the most critical mistakes is failing to validate and sanitize user input. This oversight opens doors to attacks like SQL injection and cross-site scripting (XSS).

Example Mistake:

$name = $_POST['name']; // Directly using user input
mysqli_query($conn, "INSERT INTO users (name) VALUES ('$name')");

Solution: Always validate and sanitize inputs:

$name = htmlspecialchars(trim($_POST['name']), ENT_QUOTES, 'UTF-8');
$stmt = $conn->prepare("INSERT INTO users (name) VALUES (?)");
$stmt->bind_param("s", $name);
$stmt->execute();

2. Relying Solely on Client-Side Validation

Client-side validation improves user experience but is easily bypassed by attackers. Relying solely on it without server-side validation can result in accepting invalid or malicious data.

Solution:
Implement both client-side and server-side validation to ensure data integrity. For example, validate email addresses using PHP's built-in functions:

if (!filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
    echo "Invalid email format";
    exit;
}

3. Exposing Sensitive Data in Form Submissions

Displaying sensitive information such as database error messages or raw data in response to form submissions can provide attackers with valuable insights.

Example Mistake:

echo "Error: " . $e->getMessage();

Solution: Use generic error messages for users and log detailed errors securely:

try {
    // Database operation
} catch (Exception $e) {
    error_log($e->getMessage()); // Log the detailed error
    echo "An error occurred. Please try again later.";
}

4. Not Using CSRF Tokens

Cross-Site Request Forgery (CSRF) attacks exploit the trust a site has in the user's browser. Without CSRF protection, attackers can execute unauthorized actions on behalf of users.

Solution: Generate and verify CSRF tokens for form submissions:

// Generate token
$_SESSION['csrf_token'] = bin2hex(random_bytes(32));

Include the token in the form:

Verify the token:

if ($_POST['csrf_token'] !== $_SESSION['csrf_token']) {
    die("Invalid CSRF token");
}

5. Improper Handling of File Uploads

Handling file uploads incorrectly can lead to security vulnerabilities such as remote code execution or overwriting critical files.

Example Mistake:

move_uploaded_file($_FILES['file']['tmp_name'], "uploads/" . $_FILES['file']['name']);

Solution:

• Validate the file type and size.
• Use a unique name for the uploaded file.
• Store uploads outside the web root.

$allowed_types = ['image/jpeg', 'image/png'];
if (!in_array($_FILES['file']['type'], $allowed_types)) {
    die("Invalid file type");
}

$unique_name = uniqid() . basename($_FILES['file']['name']);
move_uploaded_file($_FILES['file']['tmp_name'], "/secure/uploads/" . $unique_name);

Avoiding these common mistakes can significantly improve the security and functionality of PHP forms. By validating input, implementing robust server-side checks, protecting against CSRF attacks, and handling file uploads securely, developers can create safer and more reliable web applications.

Child CSS Not Reflecting in WordPress: Troubleshooting Tips

When working with WordPress, child themes are a great way to customize your website without affecting the parent theme. However, one common issue developers face is the child CSS not reflecting on the site. Here’s a detailed guide to troubleshoot and resolve this issue effectively.

1. Ensure Proper Enqueueing of Child Theme Styles

The most common cause of child CSS not reflecting is incorrect enqueueing. In your child theme's functions.php file, ensure you’re properly enqueueing the styles using the wp_enqueue_style function.

Here’s an example of how to do it:

add_action( 'wp_enqueue_scripts', 'enqueue_child_theme_styles' );
function enqueue_child_theme_styles() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
    wp_enqueue_style( 'child-style', get_stylesheet_directory_uri() . '/style.css', array( 'parent-style' ) );
}

2. Check File Paths

Make sure that:

• Your child theme’s style.css file is located in the correct directory (/wp-content/themes/your-child-theme/style.css).

• The file paths in your functions.php file are accurate.

3. Verify Style Precedence

Sometimes, child CSS may not reflect because it is being overridden by other styles. To ensure your styles take precedence:

• Use more specific selectors.

• Add !important to your CSS rules (as a last resort).

Example:

header h1 {
    color: red !important;
}

4. Clear Caches

Caching mechanisms can prevent the latest CSS changes from being visible. Be sure to:

• Clear your browser cache.
• Clear any WordPress caching plugins (e.g., WP Super Cache, W3 Total Cache).
• Purge server-side caches if you’re using services like Cloudflare.

If you’re using a plugin that minifies CSS/JS files, it might serve an outdated version of your CSS. Disable the minification temporarily to check if that resolves the issue.

5. Disable Minification

If you’re using a plugin that minifies CSS/JS files, it might serve an outdated version of your CSS. Disable the minification temporarily to check if that resolves the issue.

6. Check for Syntax Errors in CSS

A small syntax error in your CSS file can cause the entire stylesheet to fail. Use tools like CSSLint or your browser’s developer tools to identify and fix issues.

7. Ensure Child Theme is Active

It may sound obvious, but verify that your child theme is activated in the WordPress dashboard. Go to: Appearance > Themes and ensure your child theme is selected.

8. Debug Using Developer Tools

Use your browser’s developer tools (Inspect Element) to:

• Check if the child CSS file is loading.
• Identify the styles being applied or overridden.

9. Check Permissions

Ensure that the style.css file and the child theme directory have the correct file permissions (generally 644 for files and 755 for directories).

10. Fallback to Parent Theme CSS

As a temporary measure, you can add your custom styles to the parent theme’s Additional CSS section in: Appearance > Customize > Additional CSS

By following these steps, you should be able to resolve the issue of child CSS not reflecting in your WordPress site. If you’re still experiencing problems, consider reaching out to the WordPress community or checking for plugin conflicts that might interfere with your child theme.

How to Retain Query Parameters Across Pages in WordPress

Query parameters (like ?utm_source=google&utm_campaign=spring_sale) are crucial for tracking campaigns, user behavior, or passing dynamic values in URLs. Losing these parameters as users navigate a WordPress site can break analytics or disrupt user flows. Here's how you can ensure that query parameters persist across your WordPress website.

Why Retain Query Parameters?

Query parameters are often used for:

1. Tracking marketing campaigns (e.g., UTM parameters).
2. Passing dynamic data like referral codes or session information.
3. Enhancing user-specific navigation or personalization.

If query parameters disappear as users navigate the site, critical data may be lost, leading to incomplete analytics or broken flows.

Approaches to Retain Query Parameters in WordPress

1. Using JavaScript to Dynamically Update Links

A simple client-side solution is to append query parameters to all internal links on your site dynamically.

Steps:

1. Add the following code to your theme's functions.php:

   function enqueue_dynamic_query_script() {
       wp_enqueue_script('dynamic-query-params', get_template_directory_uri() . '/js/dynamic-query-params.js', array('jquery'), null, true);
   }
   add_action('wp_enqueue_scripts', 'enqueue_dynamic_query_script');
   

2. Create a file named dynamic-query-params.js in your theme’s js folder and add:

   document.addEventListener('DOMContentLoaded', function () {
       const queryParams = window.location.search;
   
       if (queryParams) {
           document.querySelectorAll('a').forEach(link => {
               if (link.href.includes(window.location.hostname)) {
                   if (link.href.includes('?')) {
                       link.href += '&' + queryParams.substring(1);
                   } else {
                       link.href += queryParams;
                   }
               }
           });
       }
   });
   
   

3. Test your site to ensure query parameters persist in all links.

2. Store Query Parameters in Session Storage

If users navigate directly (e.g., typing a URL), you can store the parameters in sessionStorage and append them dynamically.

Steps:

1. Enqueue the following JavaScript:

   function enqueue_session_params_script() {
       wp_enqueue_script('session-params', get_template_directory_uri() . '/js/session-params.js', array('jquery'), null, true);
   }
   add_action('wp_enqueue_scripts', 'enqueue_session_params_script');
   

2. Add this code to session-params.js:

   document.addEventListener('DOMContentLoaded', function () {
       const currentParams = window.location.search;
   
       if (currentParams) {
           sessionStorage.setItem('queryParams', currentParams);
       }
   
       const savedParams = sessionStorage.getItem('queryParams');
       if (savedParams) {
           document.querySelectorAll('a').forEach(link => {
               if (link.href.includes(window.location.hostname)) {
                   if (!link.href.includes(savedParams)) {
                       if (link.href.includes('?')) {
                           link.href += '&' + savedParams.substring(1);
                       } else {
                           link.href += savedParams;
                       }
                   }
               }
           });
       }
   });
   
   

3. Server-Side Solution

For a more robust approach, you can use PHP to modify links on the server.

Example Code for functions.php:

function append_query_parameters($url) {
    $queryParams = $_SERVER['QUERY_STRING'];

    if ($queryParams && strpos($url, '?') === false) {
        $url = $url . '?' . $queryParams;
    } elseif ($queryParams) {
        $url = $url . '&' . $queryParams;
    }

    return $url;
}

add_filter('the_content', function ($content) {
    global $wp;
    $queryParams = $_SERVER['QUERY_STRING'];
    if ($queryParams) {
        $content = str_replace(
            home_url(),
            home_url() . '?' . $queryParams,
            $content
        );
    }
    return $content;
});

add_filter('wp_nav_menu_items', function ($menu) {
    $queryParams = $_SERVER['QUERY_STRING'];
    if ($queryParams) {
        $menu = str_replace(
            home_url(),
            home_url() . '?' . $queryParams,
            $menu
        );
    }
    return $menu;
});

PHP: Validation of US Phone Numbers

Validating phone numbers is a crucial aspect of web development, ensuring that user inputs conform to the required format. In this article, we will explore how to validate US phone numbers using PHP.

US Phone Number Format

US phone numbers generally follow these formats:

• (123) 456-7890
• 123-456-7890
• 123.456.7890
• 1234567890
• +1 123-456-7890

Our goal is to validate these formats while rejecting invalid inputs.

PHP Function for Validation

We will use regular expressions (regex) to check if the input matches the valid US phone number patterns. Below is the PHP function for validation:

function validateUSPhoneNumber($phoneNumber) {
    // Define the regex pattern for US phone numbers
    $pattern = '/^(\+1\s?)?(\(?\d{3}\)?[\s.-]?)?\d{3}[\s.-]?\d{4}$/';

    // Check if the phone number matches the pattern
    if (preg_match($pattern, $phoneNumber)) {
        return true;
    } else {
        return false;
    }
}

Usage Example

Here’s how you can use the function in your PHP code:

$testNumbers = [
    "(123) 456-7890",
    "123-456-7890",
    "123.456.7890",
    "1234567890",
    "+1 123-456-7890",
    "123-45-6789" // Invalid
];

foreach ($testNumbers as $number) {
    if (validateUSPhoneNumber($number)) {
        echo "$number is valid.\n";
    } else {
        echo "$number is invalid.\n";
    }
}

Sample Output

(123) 456-7890 is valid.
123-456-7890 is valid.
123.456.7890 is valid.
1234567890 is valid.
+1 123-456-7890 is valid.
123-45-6789 is invalid.

If you need stricter validation, consider verifying the number format against real-world constraints, such as checking the validity of area codes or using third-party APIs for phone number validation.

Create a breadcrumb navigation for a WordPress site

To create a breadcrumb navigation for a WordPress site, where you want to include the parent page's title and links, you can use custom PHP code. Here's how you can implement it:

Code to Add Breadcrumb Navigation with Parent Page Support

You can add the following code to your WordPress theme's functions.php file or create a custom plugin:

function custom_breadcrumbs() {
    // Options
    $separator = ' » ';
    $home_title = 'Home';

    // Get the query & post information
    global $post;

    // Do not display on the homepage
    if (is_front_page()) {
        return;
    }

    // Start the breadcrumb with a link to home
    echo '';
}

How to Use:

1. Add the above function to your functions.php file.
2. Call the breadcrumb function in your theme's template files (e.g., header.php or page.php) where you want the breadcrumbs to appear:

if (function_exists('custom_breadcrumbs')) custom_breadcrumbs();

Styling the Breadcrumbs

You can add the following CSS to style the breadcrumbs:

.breadcrumbs {
    font-size: 14px;
    margin-bottom: 20px;
}
.breadcrumbs a {
    text-decoration: none;
    color: #0073aa;
}
.breadcrumbs a:hover {
    text-decoration: underline;
}
.breadcrumbs span {
    color: #333;
}

Features:

1. Parent Pages: Automatically includes parent pages in the breadcrumb trail.
2. Category Support: For posts, includes the category in the breadcrumbs.
3. Customizable Separator: You can change the $separator variable to use a different symbol.
