WooCommerce emails add reply to header

A client was having issues with bounce back due to customers entering incorrect email addresses, so I updated the outbound email address used by WooCommerce to “[email protected]”, this meant any bounce backs would go to a null mailbox instead of to their mains “[email protected]” mailbox. However, this meant when customers hit reply, it would reply to the noreply@ mailbox. Using this code, I was able to set a Reply-To header, so customers could still reply to emails.

Code

Drop this into your functions.php file and edit as required.

function woocommerceEmailAddReplyTo($headers = ”, $id = ”, $order)
{
	$replyToName = get_bloginfo(‘name’);
	$replyToEmail = get_bloginfo(‘admin_email’);

	if (is_array($headers)) {
		$headers[‘Reply-to’] = $replyToName . ‘ < ‘ . $replyToEmail . ‘>’;
	} else {
		$headers .= ‘Reply-to: ‘ . $replyToName . ‘ < ‘ . $replyToEmail . ‘>’ . “\r\n”;
	}

	return $headers;
}
add_filter(‘woocommerce_email_headers’, ‘woocommerceEmailAddReplyTo’, 10, 3);

WooCommerce admin filter products by image

A client recently asked me to add a filter to the WooCommerce admin products list so they can filter items based on if the item had an image or not. This allowed them to easily find products which had missing images so they could correct.

Why not take a look how to filter by on sale items?

Code

/*

 */
function custom__woocommerce_filter_by_hasimage($output) {
    global $wp_query;
    
    $selected = 0;
    if (isset($_GET[‘product_hasimage’])) {
        $selected = (int)$_GET[‘product_hasimage’];
    }
    
    $output .= ‘

			<option value=””>Filter by image</option>
			<option value=”1″ ‘ . (($selected === 1) ? ‘selected=”selected”‘ : ”) . ‘>Has Image</option>
			<option value=”2″ ‘ . (($selected === 2) ? ‘selected=”selected”‘ : ”) . ‘>Has No Image</option>
		</select>
	‘;
    
    return $output;
}
add_action(‘woocommerce_product_filters’, ‘custom__woocommerce_filter_by_hasimage’);



/*

    if (!is_admin() || $_GET[‘post_type’] != “product” || !isset($_GET[‘product_hasimage’]) || (int)$_GET[‘product_hasimage’] <= 0) {
        return $where;
    }
    
    // Is filter applied

WooCommerce delayed webhooks using actions scheduler

Recently been contacted by a user who needed the ability to delay the WooCommerce webhooks by x time, this would allow other processes happening on the site to finish instead of firing the webhook straight away, for example waiting for the payment process to finalise. Delaying webhooks is not common practice, however some time special case arises!

Take a look at actions scheduler if you wish to read more into the scheduler system used by WooCommerce.

Code

The following code allows you to delay several WooCommerces webhooks by a set duration (seconds) and also run in two modes.

Single Webhook, creates 1 single webhook but delayed by x seconds.
Multi Webhook, creates 2 webhooks, the normal webhook created by WooCommerce and a second repeat webhook which runs x seconds later.

function filter_woocommerce_webhook_deliver_async($true, $instance, $arg) {
    // Replace default schedule action? (single web hook fired, with delay)
    // Or schedule a seperate delayed action (default webhook fied with a second delayed web hook)
    $singleWebhook = false;
    
    // Target webhook topics
    $targetWebhookTopics = [
        ‘order.updated’,
    ];
    
    // Delay time in seconds
    $delayTime = 300;
    
    // If order.update, we want to create a seperate delayed webhook via schedule actions
    if (in_array($instance->get_topic(), $targetWebhookTopics)) {
        $payload = [‘webhook_id’ => $instance->get_id(), arg => $arg];
        $group = $singleWebhook ? ‘woocommerce-webhooks’ : ‘woocommerce-webhooks-delayed’;
        
        // Schedule a single action to run in 5 minutes, to cause the order.update to fire (delayed)
        // Make sure to run as_next_scheduled_action so multiple instances are not scheduled if one is already scheduled
        if (as_next_scheduled_action(‘woocommerce_deliver_webhook_async’, $payload, $group) === false) {
            as_schedule_single_action(time() + $delayTime, ‘woocommerce_deliver_webhook_async’, $payload, $group);
        }
    }
    
    return $true;
};
add_filter(‘woocommerce_webhook_deliver_async’, ‘filter_woocommerce_webhook_deliver_async’, 10, 3);

Fix WooCommerce webhook loop when using WooCommerce API

Problem (Quick)

Updating a product via the WooCommerce API would fire an update webhook, causing a loop of webhook and API activity which never ended.

Problem

Created a script which keeps stock levels synced between WooCommerce and a stock management system, WooCommerce WebHooks are used to set products stock levels in near real time. Using WooCommerce API new stock levels are pushed to WooCommerce, however with each API push this would trigger a product updated webhook, causing my script to reinforce the stock levels via API (causing an unlimited updating loop).

Solution

We can use woocommerce_webhook_should_deliver filter to control if a webhook should be delivered.

The following example shows how I used the clients IP address (in this example my scripts server) to stop webhook delivery for any requests from that IP address, this allows my script to use the API and webhooks will never be delivered.

function custom_woocommerce_webhook_should_deliver($shouldDeliver, $webhookObject, $arg) {
	// Is this a REST request?
        if (defined(‘REST_REQUEST’) && REST_REQUEST) {
		// Determine IP address
		if (!empty($_SERVER[‘HTTP_CLIENT_IP’])) {
			//check ip from share internet
			$ip = $_SERVER[‘HTTP_CLIENT_IP’];
		} elseif (!empty($_SERVER[‘HTTP_X_FORWARDED_FOR’])) {
			// to check ip is pass from proxy
			$ip = $_SERVER[‘HTTP_X_FORWARDED_FOR’];
		} else {
			$ip = $_SERVER[‘REMOTE_ADDR’];
		}
		
		if ($ip == ‘123.123.123.123’) {
			$shouldDeliver = false;
		}
	}

	return $shouldDeliver;
}
add_filter(‘woocommerce_webhook_should_deliver’, ‘custom_woocommerce_webhook_should_deliver’, 10, 3);

WooCommerce fix slow or delayed webhooks and achieve instant webhook firing

I’ve recently been working on a project which synced data between WooCommerce and an internal warehouse system, I was utilising the WooCommerce webhooks to achieve near real time syncing between the two systems, without having the creating API scripts to poll for data on a regular basis.

The Problem?

There was a delay ranging from couple seconds to 1 minute, WooCommerce uses a system called actions scheduler, this is an improved wordpress cron, allowing background processing to occur within WordPress for single or recurring actions. This is great and what WooCommerce utilises for its web hook system, however it is backed by the word press cron and the next load of scheduled actions will run on the next cron run (every 1 minute).

For this project, I needed the web hooks to fire as soon as the button was clicked, and a possible delay up to 1 minute was to long.

Fix

Disable async web hooks, web hooks will not fire as soon as they are created as part of the browser request.

/*
 * WooCommerce Disable async webhook delivery
 */
function custom_woocommerce_disable_async_webhook() {
	return false;
}
add_filter(‘woocommerce_webhook_deliver_async’, ‘custom_woocommerce_disable_async_webhook’);

/*

function custom_woocommerce_disable_async_webhook() {

return false;

}

add_filter(‘woocommerce_webhook_deliver_async’, ‘custom_woocommerce_disable_async_webhook’);

I would recommend you test your site after doing this change, for example order webhooks will fire when a customer creates a new order, which could lead to a slow user experience.

WooCommerce admin products filter by on sale

I needed the ability to filter the WooCommerce products list within admin by products which where on sale. This was to allow the client to easily find products they have put on offer within certain categories. The below code achieves this.

It does need some work, as it currently ignores the on sale start and end dates, however you should be able to easily modify it for this purpose.

/*

function custom_woocommerce_filter_by_onsale($output) {

    $selected = filter_input(INPUT_GET, ‘product_sale’, FILTER_VALIDATE_INT);
    if ($selected == false) {
        $selected = 0;
    }
	
	$output .= ‘

			<option value=””>Filter by sale</option>
			<option selected=”selected” value=”1″>On sale</option>
			<option selected=”selected” value=”2″>Not on sale</option>
		</select>
	‘;
	
	return $output;
}
add_action(‘woocommerce_product_filters’, ‘custom_woocommerce_filter_by_onsale’);

WooCommerce products filter by tags within admin

Need the ability to filter the WooCommerce products list within admin by tags? Snippet of code below is for you. This concept can be edited for other purposes.

This can be easily changed to work in different scenarios.

WordPress remove Yoast SEO post filters

Yoast SEO is a great SEO tool, I install it on most of the websites I build, but somes times I just dont need or want the filters it adds at the top of the admin posts pages. The most annoying one is when it adds it to products on a WooCommerce store.

Below snippet will remove the Yoast SEO filters from admin.

This could be upgraded for future use, for example only remove fields on WooCommerce product lists.

/*

Fix for WooCommerce schema data missing brand and mpn

UPDATED 25/10/2021 to comply with latest google changes.

Today I came across and issue where Google Search Console was complaning products “brand” and “mpn” where missing from the products schema / rich snippets data. You can checking using the rich snippet testing tool by Google found here.

I fixed my issue by adding a WordPress filter using the “woocommerce_structured_data_product” filter option. This allows you to add new data to the already generated WooCommerce data.

This is an example. You will need to change for your implementation.

/*
 * Rich Snippet Data
 * Add missing data not handled by WooCommerce yet
 */
function custom_woocommerce_structured_data_product ($data) {
	global $product;
	
	$data[‘brand’] = $data[‘brand’] = [‘@type’ => ‘Brand’, ‘name’ => $product->get_attribute(‘pa_manufacturer’) ?? null];
	$data[‘mpn’] = $product->get_sku() ?? null;
	
	return $data;
}
add_filter( ‘woocommerce_structured_data_product’, ‘custom_woocommerce_structured_data_product’ );
