Do you want to learn how to use WooCommerce hooks? You’re in the right place! In this guide, we will show you how to use action and filter hooks. Besides, we will provide you with many examples that you can apply to your WooCommerce store!

When you install WooCommerce on your website, you have access to a long list of new hooks that extend your possibilities to develop a customized solution. WooCommerce hooks work the same as native WordPress hooks and allow you to execute custom scripts on any WooCommerce page.

Similar to WordPress hooks, there are two types of WooCommerce hooks: action or filter. The action hook allows you to insert some script, while the filter hooks receive original data and return it with some kind of modification.

Syntax of WooCommerce hooks

WooCommerce hooks follow the same syntax as WordPress hooks.

Action hook

add_action(‘name_of_the_action_hook’,’your_action_hook_funcion’);

Filter hook

add_filter(‘name_of_the_filter_hook’,’your_filter_hook_funcion’);

After declaring the hook, you have to add your scripts in the function:

function your_action_hook_funcion(){
# your code here
}

Filter hooks must return some data in a parameter of the function:

function your_filter_hook_function($data){
# your code that modifies $data
return $data;
}

To see a WooCommerce hook in action, paste the following code in the functions.php file of your Child Theme:

add_action( 'woocommerce_product_meta_start', 'quadlayers_woocommerce_hooks');
function quadlayers_woocommerce_hooks() {
echo '<img src="https://kokohai.com/wp-content/uploads/2020/02/logo-kokohai-tienda-de-merchandising-de-anime-y-maga-e1584570981420.png">'; // Change to desired image url
}

This is the most basic example, where you are adding an image to all product pages. The image will be displayed under the Add to cart button, before metadata of the product.

As you can see, the name of the hook, woocommerce_product_meta_start, is self-explanatory and tells you exactly where this hook allows you to insert your code.

Useful examples of WooCommerce Hooks

Now, let’s have a look at some examples of useful things you can do with WooCommerce hooks.

NOTE: Before you start, we recommend you create a child theme. If you’re not familiar with them, you can check out our guide on how to create a child theme and the list of the best child theme plugins.

If you’re just starting with hooks, you can simply copy these scripts and paste them in the functions.php file of your child theme. Then, as you feel more comfortable, you can edit the scripts and create a different logics.

Add a description to the Shop Page

By default, the Shop Page doesn’t show the description. However, you can enable it using the woocommerce_archive_description hook as follows:

function quadlayers_shop_description() {
$description = '<p>Welcome to my shop, please be generous and buy many things, thank you.</p>';
echo $description;
}

add_action('woocommerce_archive_description', 'quadlayers_shop_description');

Add information note after Add to Cart button

WooCommerce cart hooks allow you to insert custom scripts in many sections of the cart page. Here, we’ll show you how to add a text after the Add to cart button.

This script will print a custom text after the Add to Cart button.

add_action( 'woocommerce_after_add_to_cart_form', 'quadlayers_after_addtocart_button' );
function quadlayers_after_addtocart_button() {
	// NOTE: replace your category slugs for 'music' && replace /delivery-costs/ for a valid url
	if ( is_product() && has_term( array( 'music' ), 'product_cat' ) ) {
		echo '<div style="clear: both"></div><div style="margin-top: 10px">;<a href="/delivery-costs/" target="_blank" rel="noopener"><i class="fa fa-truck" aria-hidden="true"></i>  Spend $ 100 and get free delivery;</a></div>
'; } }

You can use this to promote discounts that require minimum spending or free delivery for example.

Code explanation

• The hook woocommerce_after_add_to_cart_form prints the HTML code after the button.
• We check if the current page is a product page and if it has our specified category.
• Use category slug within an array. This way, you can check several categories.
• Echoed content allows HTML tags, variables, and anything else within the PHP scope.

Add text to a specific product taxonomy

Now, let’s see how to use WooCommerce hooks to display a message in products with a specific tag. For example, we’ll show a message offering a discount for certain products.

Remember to tag the product first.

add_action( 'woocommerce_before_single_product', 'my_product_notice_function' );
function my_product_notice_function() { 
if ( is_product() && has_term( ‘discount-25’,'product_tag' ) ) {
echo '<p><strong>This product applies for a 25% discount for the next 48 hours!</strong></p>';
}
}

Code explanation

1. 1. We use woocommerce_before_single_product hook to display a message on the top of the product page.
   2. Inside the function, we use a conditional on is_product() to make sure that it’s a product page.
   3. And has_term() checks if the current product has the “discount-25” tag.
   4. Then, print your message in the if statement.

Block purchase from logged out users

WooCommerce hooks allow you to disable the Add to cart button on product pages for logged out users. This can be useful for products or offers only available for subscribers or members. To complete the example, we will add a second hook to display a message when the purchase button is disabled.

The woocommerce_is_purchasable filter hook will block the purchase and the woocommerce_before_single_productaction hook will display the message.

add_action( 'woocommerce_before_single_product', 'quadlayers_add_message');
add_filter( 'woocommerce_is_purchasable', 'quadlayers_block_admin_purchase' );
function quadlayers_block_admin_purchase($block) {
if ( is_user_logged_in() ):return true;
else:return false;
endif;
}

function quadlayers_add_message( ){
if ( !is_user_logged_in() ):echo '<H2 style="margin-bottom:25px; text-align:center; background-color:red; font-weight:bold; color:wheat;">PLEASE LOGIN TO PURCHASE THIS PRODUCT</h2>';
endif;
}

Code explanation

1. We use the action hook to print a message and the filter hook to disable the Add to cart button.
2. The woocommerce_is_purchasable filter hook will be true if the user is logged in and false if they’re logged out.
3. We also use a conditional if() statement to apply the conditions only to logged out users in both functions (Add to cart button disabled and the message).
4. Finally, we’ve added some CSS styling to the message, enclosed in an H2 HTML tag.
