A WooCommerce fan asked me: “How do you deny checkout if the cart weight is above a certain threshold?“.
Well, this is straight forward thanks to a WooCommerce core function called “cart_contents_weight” which allows you to get the total weight of your cart, and then the “wc_add_notice” function which shows a notification error.
Enjoy!
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 ) {
$max_weight = 100;
if ( WC()->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' );
}
}
Sadly, it doesn’t work anymore
I find that very unlikely. Did you say it used to work before? What did you do recently in regard to plugin updates etc.?
If this snippet is supposed to be working on the cart page, then it has stopped working…
No, this triggers on the checkout page only
Hello,
your code is good, but it did nothing on the checkout page.
From another code that actually didn’t work, I changed your code trigger from:
woocommerce_after_checkout_validation
to
woocommerce_check_cart_items
which worked for me and is also what I wanted.
Thank you anyway. The altered code is:
add_action( 'woocommerce_check_cart_items', 'bbloomer_deny_checkout_if_weight' ); function bbloomer_deny_checkout_if_weight( $posted ) { $max_weight = 15; if ( WC()->cart->cart_contents_weight > $max_weight ) { $notice = 'Maximálnà hmotnost jedné objednávky je většà než ' . $max_weight . get_option( 'woocommerce_weight_unit' ); wc_add_notice( $notice, 'error' ); } }Nice thank you!
Hello, how can I use this code with a min weight for checkout? I tried
instead of
and also tried to change the value to a negative value like
, but both won’t work unfortunately. Thanks!
Hello Vasco, thanks so much for your comment! Yes, this is definitely possible, but I’m afraid it’s custom work. If you’d like to get a quote, feel free to contact me here. Thanks a lot for your understanding!
how can i restrict bulky items shipping for local and extended area only. No shipping to nation wide for bulky items

Is there a way to modify or adapt this snippet to
1) trigger on combined weight of a specific category
2) trigger a “request for quote” button
Thanks

Is it possible to deny checkout on specific weeks or months? Like for instance, Once the user checkout already last week, he cannot able to checkout this week, should have 2 – 3 weeks to be able to checkout again.

Is it possible to have the invoice payment gateway option open so that the customer can send the order through?
I have to calculate the freight manually over 88kg and I would like to disable the other payments to avoid customers paying through card.

Awesome Snippet 🙂
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.
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
