WooCommerce Cart Page Hooks Visual Representation

Here’s the visual representation of the cart page hooks mentioned above. 

This list covers the most commonly used hooks on the WooCommerce cart page, allowing you to add, modify, or remove content at specific sections to customize the appearance and functionality of the cart page. 

Remember that WooCommerce is highly extensible, and additional hooks can be added by third-party plugins or custom code. For more details and specific use cases, it is recommended to consult the official WooCommerce documentation.

Following is the detail and example of each hook. 

1. woocommerce_before_cart

This hook is used to display content before the cart page. It is typically used to add introductory text, notices, or promotional messages at the top of the cart page.

1.1. Add Text Using the woocommerce_before_cart Hook

To use the woocommerce_before_cart hook, we need to create a function to output the desired text before the cart. Then we need to use the add_action() to hook our custom function. 

The first parameter of the add_action() function is the hook name (woocommerce_before_cart), and the second parameter is the name of our custom function (woosuite_add_text_before_cart).

Following is the code example of using the woocommerce_before_cart hook. 

function woosuite_add_text_before_cart() {
    echo '<p>This is a custom text displayed before the cart.</p>';
}
add_action( 'woocommerce_before_cart', 'woosuite_add_text_before_cart' );

1.2. Final Results

Following is the result after adding the above code to my demo store. 

2. woocommerce_before_cart_table

This hook allows you to add content before the cart table. It can be used to display additional information, notices, or custom HTML elements above the cart items.

2.1. Add Text Using the woocoommerce_before_cart_table Hook

To use the woocommerce_before_cart_table hook, we need to create a function woosuite_add_text_before_cart_table() to output the desired text before the cart. Then we need to use the add_action() to hook our custom function. 

The first parameter of the add_action() function is the hook name (woocommerce_before_cart_table), and the second parameter is the name of our custom function (woosuite_add_text_before_cart_table).

Following is the code example of using the woocommerce_before_cart_table hook. 

function woosuite_add_text_before_cart_table() {
    echo '<p>This is a custom text before the cart table.</p>';
}
add_action( 'woocommerce_before_cart_table', 'woosuite_add_text_before_cart_table' );

3.1. Add Content Using the woocommerce_before_cart_contents Hook

To use the woocommerce_before_cart_contents hook, we need to create a function woosuite_custom_content_before_cart_items() to output the desired text before the cart. Then we need to use the add_action() to hook our custom function. 

The first parameter of the add_action() function is the hook name (woocommerce_before_cart_contents), and the second parameter is the name of our custom function (woosuite_custom_content_before_cart_items).

Following is the code example of using the woocommerce_before_cart_contents hooks.

This hook allows you to add content inside each cart item’s name. It can display additional details, such as variations, attributes, or custom labels alongside the product name.

4.1. Customize the Product Name Using the woocommerce_cart_item_name Hook

The following code defines a function named woosuite_custom_cart_item_name that accepts three parameters: $product_name, $cart_item, and $cart_item_key. This function will be called when the woocommerce_cart_item_name filter hook is triggered.

Inside the function, the product ID is extracted from the $cart_item array using $cart_item[‘product_id’] and stored in the $product_id variable.

The product name is then modified by adding a custom prefix using the concatenation operator (.). The modified product name is stored back in the $product_name variable.

Finally, the modified product name is returned using the return statement from the function.

The add_filter() function registers the woosuite_custom_cart_item_name function as a filter callback for the woocommerce_cart_item_name hook. The priority is set to 10, and the number of accepted arguments is set to 3 (matching the parameters of the callback function).

Code: 

function woosuite_custom_cart_item_name($product_name, $cart_item, $cart_item_key) {
    // Get the product ID
    $product_id = $cart_item['product_id'];
    
    // Modify the product name
    $product_name = 'Custom Prefix: ' . $product_name;
    
    // Return the modified product name
    return $product_name;
}
add_filter('woocommerce_cart_item_name', 'woosuite_custom_cart_item_name', 10, 3);

After adding the above code to my demo store, here are the final results.

5. woocommerce_cart_item_quantity

This hook displays content for the quantity field of each cart item. It can modify the quantity input field or add custom elements related to the item quantity.

5.1. Add Custom Label Before Each Item’s Quantity 

The code defines a function named woosuite_custom_cart_item_quantity that modifies the display of the quantity for each item in the WooCommerce cart. It takes three parameters: $product_quantity, $cart_item_key, and $cart_item.

Inside the function, it retrieves the product title associated with the cart item using the get_the_title function and stores it in the variable $product_name.

Then, it adds a label before the quantity value by modifying the $product_quantity variable. The label is created using an HTML span element with a class of “quantity-label” and the text “Quantity:”.

Finally, the modified $product_quantity is returned.

The code also includes a hook that adds the woosuite_custom_cart_item_quantity function as a filter for the woocommerce_cart_item_quantity hook with a priority of 10 and a parameter count of 3. 

This ensures that the woosuite_custom_cart_item_quantity function is called when the cart item quantity is displayed, allowing it to modify the output.

Code: 

function woosuite_custom_cart_item_quantity($product_quantity, $cart_item_key, $cart_item) {
    $product_name = get_the_title($cart_item['product_id']);
    
    // Add a label before the quantity
    $product_quantity = '<span class="quantity-label">Quantity:</span> ' . $product_quantity;

    return $product_quantity;
}
add_filter('woocommerce_cart_item_quantity', 'woosuite_custom_cart_item_quantity', 10, 3);

6. woocommerce_cart_item_price

This hook is responsible for displaying content for the price of each cart item. It is commonly used to modify how the item price is displayed, add custom formatting, or include additional pricing information or text.

6.1. Add Custom Text Before the Price Using the woocommerce_cart_item_price Hook

The code defines a function named woosuite_modify_cart_item_price that modifies the item’s displayed price in the WooCommerce cart. It takes three parameters: $price, $cart_item, and $cart_item_key.

The function appends a custom text “(Special Offer: Purchase 3 and Get 20% Off)” before the original price. The modified price is stored in the variable $modified_price.

Finally, the modified price is returned from the function, and the function is hooked to the woocommerce_cart_item_price filter with a priority of 10 and 3 parameters. This means that whenever the cart item price is displayed, this function will be called to modify and return the price.

Code:

function woosuite_modify_cart_item_price($price, $cart_item, $cart_item_key) {
    
    // Example: Add a custom text before the cart item price.
    $modified_price = '(Special Offer: Purchase 3 and Get 20% Off)  ' . $price;

    return $modified_price;
}
add_filter('woocommerce_cart_item_price', 'woosuite_modify_cart_item_price', 10, 3);

I simply created a function(woosuite_add_custom_coupon_message()) and added the content I wanted to display below the coupon button. After that, using the add_action() function, I specified the location(woocommerce_cart_coupon) where I wanted to display the content and called the function. 

It is a very simple example, but you can add whatever code you want inside the function. 

Code:

// Add a custom message below the coupon field on the cart page
function woosuite_add_custom_coupon_message() {
    echo '<p>This is a custom coupon message.</p>';
