Adding a quantity in WooCommerce is pretty simple. You just need to add a few lines of code to your functions.php file. You can do this by going to your WordPress Dashboard and navigating to Appearance > Editor.

Once you’re in the editor, find the functions.php file on the right hand side and click on it. Then, scroll down to the very bottom of the file and add the following code:

// Add a custom field to each product in the cart

add_filter( ‘woocommerce_checkout_cart_item_quantity’, ‘add_custom_field_to_cart_item_quantity’, 10, 3 );

function add_custom_field_to_cart_item_quantity( $product, $cart_item, $cart_item_key ) {

// Get the value from our custom field

$product[‘quantity’] = WooCommerce_quantity_input( array(

‘input’ => get_post_meta( $product->id, ‘my-custom-field’, true ),

‘max’ => $product->get__stock(),

‘min’ => ‘0’,

‘step’ => $product->get__stock(‘min’),

), $product, false );

return $product; }

PRO TIP: If you are planning to add a quantity in WooCommerce, be aware that there is a potential for errors. Make sure that you have a backup plan in place in case something goes wrong.

Conclusion:

That’s it! You’ve now added a quantity input field to your WooCommerce products. This is a great way to give your customers more control over their purchase.
