Ok, I just sent u a message. I really would like to be able to do that through your plugin, since my client would be able to manage that by himself. However, I also would like to know how to do that through php. I do not know if that is on your scope, so here is the code, which is not working, do you know tell me why?

//https://rudrastyh.com/woocommerce/custom-checkout-validation.html - hook woocommerce_after_checkout_validation did not work
//https://stackoverflow.com/questions/28603144/custom-validation-of-woocommerce-checkout-fields
add_action( 'woocommerce_after_checkout_validation', 'misha_validate_fname_lname', 10, 2);
 
function misha_validate_fname_lname( $fields, $errors ){
 
    if ( strpos( $fields[ 'billing_n_matricula' ], 300) === false   ){
        $errors->add( 'validation', 'Seu número de matrícula parece estar errado, favor digitar o correto.' );
    }
}

It seems the code runs, since I see the validation warning, but it never gets true, to go ahead. Tks!

We have checked the code in detail. The issue is that, the second argument for the strpos will be a string type. Here in the code it is used as an integer type. Please change the code as per the below snippets.

add_action( 'woocommerce_after_checkout_validation', 'misha_validate_fname_lname', 11, 2);
function misha_validate_fname_lname( $fields, $errors ){
    if ( strpos( $fields[ 'billing_n_matricula' ], '300') === false   ){
        $errors->add( 'validation', 'Seu número de matrícula parece estar errado, favor digitar o correto.' );
    }
}

Hope this will help ??

Thank you!
