Create a coupon programatically in WooCommerce

We will need to add this code to our child theme’s functions.php file or via a plugin that allows custom functions to be added. We always have to remember, we don’t have to add custom code directly to our parent theme’s functions.php file as this will be wiped entirely when we update the theme.

/**
 * Create a coupon programatically
 */
$coupon_code = 'UNIQUECODE'; // Code
$amount = '10'; // Amount
$discount_type = 'fixed_cart'; // Type: fixed_cart, percent, fixed_product, percent_product
     
$coupon = array(
 'post_title' => $coupon_code,
 'post_content' => '',
 'post_status' => 'publish',
 'post_author' => 1,
 'post_type'  => 'shop_coupon'
);
     
$new_coupon_id = wp_insert_post( $coupon );
     
// Add meta
update_post_meta( $new_coupon_id, 'discount_type', $discount_type );
update_post_meta( $new_coupon_id, 'coupon_amount', $amount );
update_post_meta( $new_coupon_id, 'individual_use', 'no' );
update_post_meta( $new_coupon_id, 'product_ids', '' );
update_post_meta( $new_coupon_id, 'exclude_product_ids', '' );
update_post_meta( $new_coupon_id, 'usage_limit', '' );
update_post_meta( $new_coupon_id, 'expiry_date', '' );
update_post_meta( $new_coupon_id, 'apply_before_tax', 'yes' );
update_post_meta( $new_coupon_id, 'free_shipping', 'no' );

WooCommerce Account Page Custom Endpoint

We can do it using below simple steps. We have to add the below code given in steps in our theme functions.php or in plugin code.

Step 1: In this post, we will see how we can add custom endpoint to my account page in front means one new our own page like order, download (default one’s). To do this, first we’ll add rewrite endpoint using WordPress function ‘add_rewrite_endpoint’ on ‘init’ hook.

function aft_custom_endpoint() {
  add_rewrite_endpoint( 'custom', EP_ROOT | EP_PAGES );
}
 
add_action( 'init', 'aft_custom_endpoint' );

Step 2: Now, we will add menu item for this custom endpoint on WooCommerce My Account page menu so that we can access easily. For this we’ll use ‘woocommerce_account_menu_items’ filter.

add_filter( 'woocommerce_account_menu_items', 'aft_new_menu_items' );
 
/**
* Insert the new endpoint into the My Account menu.
*
* @param array $items
* @return array
*/
function aft_new_menu_items( $items ) {
    $items[ 'custom' ] = __( 'Custom', 'webkul' );
    return $items;
}

The above code will add one more menu item named Custom at the end of my account page menu list.

Step 3: The endpoint has been added, menu item also added, now next thing will be, how can we add content to this new (say) page..? Not to worry, WooCommerce provide the hook using which we can add content –

$endpoint = 'custom';
 
add_action( 'woocommerce_account_' . $endpoint .  '_endpoint', 'aft_endpoint_content' );
 
function aft_endpoint_content() {
    //content goes here
    echo '//content goes here';    
}

Now lets just add a custom fields value to our post. After checking the custom fields checkbox, scroll down to the page to see the Custom Fields box.

With the help of of some if else conditional statement we can check weather the our custom fields name has a value or not.

$key = 'sub-heading';
$themeta = get_post_meta($post->ID, $key, TRUE);
if($themeta != '') { 
 echo '
'.get_post_meta($post->ID, 'sub-heading', true).'

HTML5 default validation for confirm password

In this section, we am going to see how you we easily validating HTML5 default validation for confirm the password. Generally in HTML5 when we create a form we simply write “required” attribute to the form element and it starts validating itself without other javascript code. But for confirm password validation we would required to add few lines of code that will set the validation in the default way.

HTML

Confirm password with HTML5
        
        

        
    

JAVASCRIPT

var password = document.getElementById("password")
, confirm_password = document.getElementById("confirm_password");

function validatePassword(){
if(password.value != confirm_password.value) {
confirm_password.setCustomValidity("Passwords Don't Match");
} else {
confirm_password.setCustomValidity('');
}
}

password.onchange = validatePassword;
confirm_password.onkeyup = validatePassword;

Wordpress Update User's Password with PHP

wp_update_user( array ('ID' => $user_id, 'user_pass' => $newpassword) ) ;

Get first letter of each word for a given string in PHP

QUESTION:How would I get the first letter of each word for a given string?

$string = "This Is The TEST String";
$result = "TITTS";

ANSWER: explode() on the spaces, then you use the [] notation to access the resultant strings as arrays:

$words = explode(" ", "This Is The TEST String");
$acronym = "";

foreach ($words as $w) {
  $acronym .= $w[0];
}

If you have an expectation that multiple spaces may separate words, switch instead to preg_split()

$words = preg_split("/\s+/", "This Is The TEST String");

Or if characters other than whitespace delimit words (-,_) for example, use preg_split() as well:

// Delimit by multiple spaces, hyphen, underscore, comma
$words = preg_split("/[\s,_-]+/", "This Is The TEST String");

Contact Form 7 AJAX Callback

Question :
Been searching around on this for a while and can't come up with any documentation to outline what i want to achieve.
I'm using wordpress and the Contact Form 7 plugin, all is working perfectly, what i want to achieve is to run some particular javascript upon form submit, I know we can use "on_sent_ok:" in the additional settings, but this only performs if the form is actually submitted.
What I'd like to do is to do some other javascript when the form doesn't submit ok, which throws the user back to the section which didn't validate.

Contact Form 7 AJAX Callback

Solution code for : Contact Form 7 AJAX Callback
Given the variety of responses on this topic the plugin developer seems to change their mind about how this should work every 5 minutes.

document.addEventListener( 'wpcf7mailsent', function( event ) {
  alert( "Fire!" );
}, false );

And the valid events are:

• wpcf7invalid — Fires when an Ajax form submission has completed successfully, but mail hasn’t been sent because there are fields with invalid input.
• wpcf7spam — Fires when an Ajax form submission has completed successfully, but mail hasn’t been sent because a possible spam activity has been detected.
• wpcf7mailsent — Fires when an Ajax form submission has completed successfully, and mail has been sent.
• wpcf7mailfailed — Fires when an Ajax form submission has completed successfully, but it has failed in sending mail.
• wpcf7submit — Fires when an Ajax form submission has completed successfully, regardless of other incidents.

Redirect contact form 7 with javascript

Soution code for : Redirect contact form 7 with javascript
Seen as you are using jquery anyway, you can add the click on the submit button like this

jQuery( document ).ready(function() {
    jQuery("#aft_submit").on('click', function(e){
        e.preventDefault();
        window.location.href  = "http://url-to-redirect.com";
    });
}

You'll need to prevent the default 'submit' action

Wordpress Contact form 7 custom shortcodes

Question :
Contact form 7 has some shortcodes, like [_date] to get todays date. But I want to display the date one week from now.
So I need to create a custom shortcode to Contact form 7 that takes say [next_week] and in the received email the correct date is displayed.
Where and how do I create custom shortcodes to Contact form 7?
Solution code for : Wordpress Contact form 7 custom shortcodes
Adding the following to your functions.php

wpcf7_add_shortcode('custom_date', 'wpcf7_custom_date_shortcode_handler', true);

function wpcf7_custom_date_shortcode_handler($tag) {
    if (!is_array($tag)) return '';

    $name = $tag['name'];
    if (empty($name)) return '';

    $next_week = date('Y-m-d', time() + (60*60*24*7)); 
    $html = '';
    return $html;
}

Now in the "Form" field in CF7 GUI type [custom_date next_week]
Now you can use [next_week] in the message body.
