Introduction:

One common functionality that store owners often need is to retrieve the quantity of a particular product in a customer’s cart. In this post, we’ll walk you through the steps to achieve this using WooCommerce hooks and functions. Let’s dive in!

Step 1: Identify the product to retrieve its quantity

To begin with, you need to know the product ID or product SKU for the item whose quantity you want to retrieve. You can find this information in the WooCommerce Products section in your WordPress dashboard. Once you have the product ID or SKU, you can proceed to the next step.

Step 2: Create a custom function to get the product quantity

Now, you need to create a custom function that will retrieve the quantity of the specified product from the cart. You can add this function to your theme’s functions.php file or in a custom plugin file. Here’s a sample code snippet:

function get_product_quantity_from_cart( $product_id ) {
  $quantity = 0;

  // Check if the cart is not empty
  if ( ! WC()->cart->is_empty() ) {
    // Loop through the cart items
    foreach ( WC()->cart->get_cart() as $cart_item ) {
      // Check if the current cart item matches the specified product ID
      if ( $cart_item['product_id'] == $product_id ) {
        // Update the quantity
        $quantity = $cart_item['quantity'];
        break;
      }
    }
  }

  return $quantity;
}

This function checks if the WooCommerce cart is not empty and then loops through the cart items. If the product ID matches the specified product, it retrieves the quantity and breaks the loop.

Step 3: Use the custom function in your theme or plugin

Now that you have the custom function, you can use it in your theme or plugin to display the quantity of the specified product in the cart. For example, you can call the function like this:

$product_id = 123; // Replace with your product ID
$quantity = get_product_quantity_from_cart( $product_id );
echo 'The quantity of product ID ' . $product_id . ' in the cart is: ' . $quantity;

This will output the quantity of the specified product in the cart.

Conclusion:

Retrieving the quantity of a product in the WooCommerce cart is a straightforward process. By creating a custom function and using it in your theme or plugin, you can efficiently access this information and use it for various purposes like displaying stock availability, offering dynamic discounts, or managing shipping options. With a bit of creativity, you can customize your WooCommerce store to better serve your customers and improve their shopping experience.
