If you’re running an online store using WooCommerce, you’ll want to ensure that your customers have a seamless shopping experience. One way to achieve this is by allowing them to easily update their cart as they add or remove products. In this post, we’ll show you how to update the WooCommerce cart by adding PHP code.

Step 1: Locate the WooCommerce Cart Template

The first step is to locate the WooCommerce cart template. This is the file that controls how the cart is displayed on your website. To find it, go to your theme directory and look for the folder named “woocommerce“. Inside this folder, you’ll find a file named “cart.php”. This is the file we’ll be working with.

Step 2: Add the PHP Code

Next, we need to add the PHP code that will allow us to update the cart. Open the “cart.php” file in your text editor and find the line of code that displays the quantity of each product in the cart. It should look something like this:

<?php echo $product['quantity']; ?>

Replace this line with the following code:

<input type="number" name="quantity[<?php echo $cart_item_key; ?>]" value="<?php echo $product['quantity']; ?>" class="input-text qty text" />

This will replace the quantity display with an input field where customers can manually enter the quantity they want. The code also includes the cart item key, which is required to update the cart.

Step 3: Add the Update Button

Now that we have the input field, we need to add a button that customers can click to update the cart. Below the input field, add the following code:

<button type="submit" name="update_cart" value="Update cart" class="button">Update cart</button>

This code will add a button labeled “Update cart” that customers can click to update the cart with their desired quantities.

That’s it! With these changes, your customers can now easily update their cart as they shop on your website.
