    Here are two scenarios where the keyup event will not get fired: The user drags text into the textarea. The user copy-paste text in the textarea with a right click (contextual menu).

    Use the HTML5 input event instead for a more robust solution:

    // jquery
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.4/jquery.min.js"></script>
    
    // html
    <div class="control">
    	<textarea spellcheck="true" maxlength="200" name="question" id="question" class="input-textarea required-entry" cols="5" rows="8" data-validate="{required:true}" aria-required="true"></textarea>
      <div class="limittext"><span class="charnum">200 Characters left</span></div>
    </div>
    
    <script type="text/javascript">
    jQuery(document).ready(function() {
      // edit area start
      var maxLength = 200;
      var textarea_id = "question";
      // edit area end
    
      var html='<span style="color:red;">'+ maxLength + ' characters allowed, excess characters trimmed</span>';
      jQuery("#"+textarea_id).on('input',function(){
          var length = this.value.length;
          if (length >= maxLength) {
            this.value = this.value.substring(0, maxLength);
            jQuery(this).next(".limittext").html(html);
          } else {
            var count=maxLength-length;
            jQuery(this).next(".limittext").html('<span class="charnum">' +count+' Characters left</span>');
          }
      });
    });
    </script>

    To disable this update notification, there is no switch in the settings menu or anywhere else in the admin dashboard. To prevent WordPress from showing these information snippets on top of your WordPress dashboard, you shall need to add a PHP code snippet to your functions.php file.

    add_filter('pre_site_transient_update_core','__return_null');
    add_filter('pre_site_transient_update_plugins','__return_null');
    add_filter('pre_site_transient_update_themes','__return_null');

    I'm currently displaying phone numbers like 18003336523. However, I need the number to be formatted in a more human-readable form, for example: 1-800-333-6523.

    <script>
    
    jQuery('.wpcf7-tel').keydown(function (e) {
      var key = e.charCode || e.keyCode || 0;
      $phone = jQuery(this);
    
      // Auto-format- do not expose the mask as the user begins to type
      if (key !== 8 && key !== 9) {
          
    console.log($phone.val().length);
       if ($phone.val().length === 1) {
        $phone.val($phone.val() + '-');
       }
       if ($phone.val().length === 5) {
        $phone.val($phone.val() + '-');
       }   
       if ($phone.val().length === 9) {
        $phone.val($phone.val() + '-');
       }
       if ($phone.val().length === 15) {
        return false;
       }
      }
    
      // Allow numeric (and tab, backspace, delete) keys only
      return (key == 8 || 
        key == 9 ||
        key == 46 ||
        (key >= 48 && key <= 57) ||
        (key >= 96 && key <= 105)); 
     })
     
     .bind('focus click', function () {
      $phone = jQuery(this);
      
      if ($phone.val().length === 0) {
       //$phone.val('(');
      }
      else {
       var val = $phone.val();
       $phone.val('').val(val); // Ensure cursor remains at the end
      }
     })
     
     .blur(function () {
      $phone = jQuery(this);
      
      if ($phone.val() === '(') {
       $phone.val('');
      }
     });
    </script>

    For a WordPress blog, pagination alludes to showing a predetermined number of posts per page. Pagination permits clients the capacity to explore substantially less demanding and more profound into the chronicles. In this post, I will demonstrate that my past instructional exercise about including Pagination without a module in WordPress, can likewise be utilized on Custom Post Types with no alterations. I will likewise demonstrate the means I took to test my past instructional exercise's pagination code and demonstrate that it is as yet substantial for custom post writes.

    <?php
    $paged = (get_query_var('page')) ? get_query_var('page') : 1;          
    $args = array( 'paged'=> $paged,'post_type' => 'product','orderby' => 'post_date','order'=> 'ASC','posts_per_page' => 10,'post_status'=>'publish');        
    
    $query = new WP_Query($args);
    if ($query->have_posts()) : 
    while ($query->have_posts()) : $query->the_post();
        $id=get_the_ID();
    ?> 
          
    <a href="<?php the_permalink() ?>" class="post-title">
        <h2><?php the_title();?></h2>
    </a>
    <div class="post-content"> <?php echo '<p>'.substr(get_the_content(),0,190).'...</p>'; ?> </div>
    
    <?php
    endwhile; endif;
    ?>
     <?php
     echo '<div class="blogPager">';
     echo '<ul class="pagination"> ';
     if( $paged-1 >= 1){
        echo ' <li class="'.($i == $paged ? 'active ' : '').'page button"><a   href="'.get_pagenum_link(($paged-1 > 0 ? $paged-1 : 1)).'"  > Previous</a></li>';
     }
    
    if($query->max_num_pages > 10) {
        for($i=1;$i<=$query->max_num_pages;$i++){
            echo '<li class="'.($i == $paged ? 'active ' : '').'page button"><a  href="'.
           get_pagenum_link($i).'">'.$i.'</a></li>';
    
        }
    }
    if( $query->max_num_pages > $paged  ) {
        echo '<li class="'.($i == $paged ? 'active ' : '').'page button"> <a   href="'.get_pagenum_link(($paged+1 <= $query->max_num_pages ? $paged+1 :
                $query->max_num_pages)).'">Next </a></li>';
    }
    echo '</ul> ';
    echo '</div> ';
    wp_reset_postdata();
    ?>

    You can specify a function identifier in a custom property in your .ajax() call and use the value of that in your ajaxComplete() callback.

    For example, get any ajax property while making your .ajax() call:
    function foo() {
        $.ajax({
            url: 'my-page.php',
        });
    }
    
    And then, use any of ajax property to ajaxComplete() like this:
    $('#my-unique-id').ajaxComplete(function(e, xhr, settings) { // run after all ajax complete 
        if (settings.url == 'my-page.php') { // write condition according to your requirement
            // execute you code
        } else {
            // execute you code
        }
    });

    If you need to change item product prices in Woocommerce Backend Order. Please use the following hook or code

    add_action( 'woocommerce_ajax_add_order_item_meta', 'VP_set_item_quantity', 99, 3 );
    function VP_set_item_quantity( $item_id, $item, $order ) {
        foreach ( $order->get_items() as $order_item_id => $order_item_data ) {
            if ( $order_item_id == $item_id ) {
    
    
                $order_item_data->set_subtotal('20.22');
                $order_item_data->set_total(20.22);
                $order->apply_changes();
                $order->save();

    This action hook allows you to access data for a new user immediately after they are added to the database. The user id is passed to hook as an argument.

    add_action( 'user_register', 'eddpremium_register_fields_save');
    add_action( 'profile_update', 'eddpremium_register_fields_save');
    
    function eddpremium_register_fields_save($user_id) {
    	$u = new WP_User($user_id);
    
    	// Remove role
    	$u->remove_role( 'subscriber' );
    
    	// Add role
    	$u->add_role( 'author' );
    }

    The hook allows meta box registration for any post type. Passes two parameters: $post_type and $post. Note: You can also use add_meta_boxes_{post_type} for best practice, so your hook will only run when editing a specific post type. This will only receive 1 parameter - $post.

    Add this to functions.php
    add_action( 'add_meta_boxes', 'gp_add_meta_boxes' );
    function gp_add_meta_boxes() {
        add_meta_box( 'gp_product', 'Products Options', 'gp_products_callback', 'review', 'normal', 'high' );
    }
    
    function gp_products_callback( $post ) {
        $fname = get_post_meta( $post->ID, 'fname', true );
    
    // reset choices
    	$field['choices'] = array();
    	
    	$users = get_users();
    	?>
    	<select name="cust_user"></select>
    	<?php
    	foreach ($users as $user) {
    		$field[ $user->ID ] = $user->display_name;
    	}
    
        ?>
        <p>First Name: <input type="text" name="fname" value="<?php echo $fname; ?>"></p>
        <?php
    }
