add_filter( 'wc_order_statuses', 'ts_rename_order_status_msg', 20, 1 );
function ts_rename_order_status_msg( $order_statuses ) {
    $order_statuses['wc-completed']  = _x( 'Order Received', 'Order status', 'woocommerce' );
    $order_statuses['wc-processing'] = _x( 'Your Order is being processed', 'Order status', 'woocommerce' );
    $order_statuses['wc-on-hold']    = _x( 'Your Order is on hold', 'Order status', 'woocommerce' );
    $order_statuses['wc-pending']    = _x( 'Your Order is pending', 'Order status', 'woocommerce' );
    return $order_statuses;
}

You will see that the order status has changed. We used the hook wc_order_statuses here and attached our function ts_rename_order_status_msg to it. The $order_statuses array that we passed as the argument contains the status messages as its first value.

The status messages also change in the front-end, where you check your order status under My account->Orders:

There are two other places though where the Woocommerce order status message gets displayed i.e. in the top menu inside the Admin Dashboard, and also in the dropdown for Bulk Actions:

These status messages can be changed too using two other hooks to which we will attach two other functions.

Add the below code to the functions.php file of your child theme to change the status message in the top menu:

foreach( array( 'post', 'shop_order' ) as $hook )
    add_filter( "views_edit-shop_order", 'ts_order_status_top_changed' );
function ts_order_status_top_changed( $views ){
    if( isset( $views['wc-completed'] ) )
        $views['wc-completed'] = str_replace( 'Completed', __( 'Order Received', 'woocommerce'), $views['wc-completed'] );
    if( isset( $views['wc-processing'] ) )
        $views['wc-processing'] = str_replace( 'Processing', __( 'In Process', 'woocommerce'), $views['wc-processing'] );
    if( isset( $views['wc-on-hold'] ) )
        $views['wc-on-hold'] = str_replace( 'On hold', __( 'Order on Hold', 'woocommerce'), $views['wc-on-hold'] );
    if( isset( $views['wc-pending'] ) )
        $views['wc-pending'] = str_replace( 'Pending payment', __( 'Payment Pending', 'woocommerce'), $views['wc-pending'] );
        return $views;
}

You can see that we have used views_edit-shop_order hook here to simply replace the String values that each array key (for different order status messages) contains.

Now, the last place that we have to change the order status messages (if necessary) is the Bulk Actions dropdown that we highlighted above. For this, we will use yet another code snippet and add it to the same functions.php file:

add_filter( 'bulk_actions-edit-shop_order', 'ts_bulk_actions_order_status', 20, 1 );
function ts_bulk_actions_order_status( $actions ) {
    $actions['mark_processing'] = __( 'Mark as In Process', 'woocommerce' );
    $actions['mark_on-hold']    = __( 'Mark as Order on Hold', 'woocommerce' );
    $actions['mark_completed']  = __( 'Mark as Order Received', 'woocommerce' );
    return $actions;
}

Here, the bulk_actions-edit-shop_order hook is being used to change the values of the different actions that are applied to orders.

You can see that the order status messages will have changed in this dropdown:

/*

*/

function woocommerce_quantity_input_min_callback( $min, $product ) {
	$min = 2;  
	return $min;

add_filter( 'woocommerce_quantity_input_min', 'woocommerce_quantity_input_min_callback', 10, 2 );

/*

*/

function woocommerce_quantity_input_max_callback( $max, $product ) {
	$max = 5;  
	return $max;
}
add_filter( 'woocommerce_quantity_input_max', 'woocommerce_quantity_input_max_callback', 10, 2 );

 //Sanitize $color if "#" is provided 
        if ($color[0] == '#' ) {
         $color = substr( $color, 1 );
        }
 
        //Check if color has 6 or 3 characters and get values
        if (strlen($color) == 6) {
                $hex = array( $color[0] . $color[1], $color[2] . $color[3], $color[4] . $color[5] );
        } elseif ( strlen( $color ) == 3 ) {
                $hex = array( $color[0] . $color[0], $color[1] . $color[1], $color[2] . $color[2] );
        } else {
                return $default;

        //Convert hexadec to rgb
        $rgb =  array_map('hexdec', $hex);
 
        //Check if opacity is set(rgba or rgb)
        if($opacity){
         if(abs($opacity) > 1)
         $opacity = 1.0;
         $output = 'rgba('.implode(",",$rgb).','.$opacity.')';
        } else {
         $output = 'rgb('.implode(",",$rgb).')';
        }
 
        //Return rgb(a) color string
        return $output;
}

Here’s a usage example how to use this function for dynamicaly created CSS:

$color = '#ffa226';
$rgb = hex2rgba($color);
$rgba = hex2rgba($color, 0.7);
 
/* CSS output */
 
echo ' 
 div.example{
  background: '.$rgb.';
  color: '.$rgba.';
 }

1. You have access to $order

Hooks (do_action and apply_filters) use additional arguments which are passed on to the function. If they allow you to use the “$order” object you’re in business. Here’s how to get all the order information:

// Get Order Dates
$order->get_date_created();
$order->get_date_modified();

// Get Order User, Billing & Shipping Addresses

// Get Order Status
$order->get_status();
 
// source: https://docs.woocommerce.com/wc-apidocs/class-WC_Order.html

2. You have access to $order_id

If you have access to the order ID (once again, usually the do_action or apply_filters might give you this), you have to get the order object first. Then do the exact same things as above.

// Get $order object from order ID
 
$order = wc_get_order( $order_id );
 
// Now you have access to (see above)...
 
$order->get_id()
$order->get_formatted_order_total( )
// etc.
// etc.

function get_custom_email_html( $order, $heading = false, $mailer ) {

	$template = 'emails/my-custom-email-i-want-to-send.php';

	return wc_get_template_html( $template, array(
		'order'         => $order,
		'email_heading' => $heading,
		'sent_to_admin' => false,
		'plain_text'    => false,
		'email'         => $mailer
	) );

}

// load the mailer class
$mailer = WC()->mailer();

//format the email
$recipient = "someone@somewhere.com";
$subject = __("Hi! Here is a custom notification from us!", 'theme_name');
$content = get_custom_email_html( $order, $subject, $mailer );
$headers = "Content-Type: text/html\r\n";

//send the email through wordpress
$mailer->send( $recipient, $subject, $content, $headers );

    function cuteHide(el) {
        el.animate({opacity: '0'}, 130, function(){
            el.animate({height: '0px'}, 130, function(){
            });
        });
    }

    function cuteUnhide(el) {
        el.animate({height: '100%'}, 130, function(){
            el.animate({opacity: '1'}, 130, function() {
            });
        });
    }
    function cuteRemove(el) {
        el.animate({opacity: '0'}, 150, function(){
            el.animate({height: '0px'}, 150, function(){
                el.remove();
            });
        });
    }

Are you looking for a way to track post views without a plugin using post meta? While there’s probably a plugin for this, we have created a quick code snippet that you can use to track post views without a plugin using post meta in WordPress.

Instructions:

Add this code to your theme’s functions.php file:

function getPostViews($postID){
    $count_key = 'post_views_count';
    $count = get_post_meta($postID, $count_key, true);
    if($count==''){
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, '0');
        return "0 View";
    }
    return $count.' Views';
}
function setPostViews($postID) {
    $count_key = 'post_views_count';
    $count = get_post_meta($postID, $count_key, true);
    if($count==''){
        $count = 0;
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, '0');
    }else{
        $count++;
        update_post_meta($postID, $count_key, $count);
    }
}
 
// Remove issues with prefetching adding extra views
remove_action( 'wp_head', 'adjacent_posts_rel_link_wp_head', 10, 0); 

Optionally add this code as well to a column in the WordPress admin that displays the post views:

// Add to a column in WP-Admin
add_filter('manage_posts_columns', 'posts_column_views');
add_action('manage_posts_custom_column', 'posts_custom_column_views',5,2);
function posts_column_views($defaults){
    $defaults['post_views'] = __('Views');
    return $defaults;
}
function posts_custom_column_views($column_name, $id){
    if($column_name === 'post_views'){
        echo getPostViews(get_the_ID());
    }
}

This part of the tracking views code will set the post views. Just place this code below within the single.php file inside the WordPress Loop.

<?php setPostViews(get_the_ID()); ?>

Note about fragment caching: If you are using a caching plugin like W3 Total Cache, the method above to set views will not work as the setPostViews() function would never run. However, W3 Total Cache has a feature called fragment caching. Instead of the above, use the following so the setPostViews() will run just fine and will track all your post views even when you have caching enabled.

<!-- mfunc setPostViews(get_the_ID()); --><!-- /mfunc -->

The code below is optional. Use this code if you would like to display the number of views within your posts. Place this code within the Loop.

<?php echo getPostViews(get_the_ID());?>

Usage example:

/* Here's a usage example how to use this function for dynamicaly created CSS */
 
$color = '#ffa226';
$rgb = hex2rgba($color);
$rgba = hex2rgba($color, 0.7);
 
/* CSS output */
 
echo '	
	div.example{
	 background: '.$rgb.';
	 color: '.$rgba.';
	}
';
