WooCommerce: Deny Checkout Based on Cart Weight

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!

Where to add custom code?

You should place PHP snippets at the bottom of your child theme functions.php file and CSS at the bottom of its style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my guide "Should I Add Custom Code Via WP Editor, FTP or Code Snippets?" and my video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything went 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.

      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, how can I use this code with a min weight for checkout? I tried 

    $min_weight

    instead of 

    $max_weight

    and also tried to change the value to a negative value like 

    $max_weight = -10;

    , but both won’t work unfortunately. Thanks!

    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.
