Extend validation to Shopping Cart

Hi Jason,

At this moment there’s no way in the plugin to run the validation rules at the cart. There would (could) be some conflicts such as address fields that aren’t set yet on the cart page.

It might be possible with some custom code to accomplish this, but I haven’t tested / done that before.

Cheers,
Jeroen

G’day Jeroen,

It’ll be great to insert a couple of snippets into functions.php to get your plugin working in the Shopping Cart page.

I need 2 condition validations.
Firstly, to check the cart contents for at least one parent category.
And secondly, to check the cart contents for another category against the shipping state.

Please advise. Thank you in advance.

Hi Jason,

You may want to check the Advanced Messages plugin of mine; this would allow you to add messages to the cart, though it wouldn’t stop people from entering the checkout.

Otherwise I’d advise to hire a developer to help with your specific requirements.

Hope that helps!

Have a great day!

I found in “/includes/wcasv-validation-functions.php” on line 118, with this line of code.

add_action( 'woocommerce_after_checkout_validation', 'wcasv_add_checkout_validation_messages' );

Is it possible to add this additional code?

add_action( 'woocommerce_add_to_cart_validation', 'wcasv_add_checkout_validation_messages' );

Hi Jason,

That would probably be when someone tries to add a product to the cart, and not in the cart itself. Also, I don’t think the notice created in that function will stop the validation, the ‘woocommerce_add_to_cart_validation’ is a filter and not a action, requiring a ‘return false’ to stop the validation.

It is close though, maybe your webdeveloper can help you customize it a bit to fit your exact requirements ??

Cheers,
Jeroen

If that’s the case, then I’ll add the snippet from
