WooCommerce: Deny Checkout Based on Cart Weight

A WooCommerca fan asked this question on a Facebook group, so I had to write a snippet about it: “How do you deny checkout if the cart weight is above a certain threshold?“. Well, this is straight forward, so there you go!

WooCommerce: show checkout error if weight exceeds a threshold

PHP Snippet: Deny WooCommerce Checkout Processing if Cart Weight > Threshold

 */

add_action('woocommerce_after_checkout_validation', 'bbloomer_deny_checkout_if_weight');

function bbloomer_deny_checkout_if_weight( $posted ) {
global $woocommerce;
$max_weight = 100;
if ( $woocommerce->cart->cart_contents_weight > $max_weight ) {
   $notice = 'Sorry, your cart has exceeded the maximum allowed weight of ' . $max_weight . get_option('woocommerce_weight_unit');
   wc_add_notice( $notice, 'error' );
}
}

Where to add this code?

You can place PHP snippets at the bottom of your child theme functions.php file (before "?>" if you have it). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such delicate files - if you need more guidance, please take a look at my free WooCommerce Customization video tutorial.

Does this snippet still work?

Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7.

  1. Awesome Snippet ๐Ÿ™‚

    I want to ask if there any way this will only show up for a regular customer, I have the wholesale plugin for WooCommerce and I don’t want that notice for that user role.

    Thanks a lot for sharing this with the community.

    1. James – thanks so much for your comment! Yes, this is possible – but unfortunately this is custom work and I cannot provide a complementary solution here via the blog comments. If you’d like to get a quote, feel free to contact me here. Thanks a lot for your understanding! ~R

  2. […] up from the other day’s snippet (deny checkout based on cart weight), you might want to show what is the current Cart Weight on the cart and checkout page. So here you […]
