Support » Plugin: EU VAT for WooCommerce - Validate & Exempt » Validation starts after first character and hides form

  • Resolved nemoprofeta

    (@nemoprofeta)


    I’ve been using the plugin for some months and I had no problems. Suddenly now it has a strange behavior.
    I sell digital products. So I normally hide fields such as the address when the customer is checking out. If he wants the invoice, he has to flag a checkbox.
    This shows the fields including the one to add the VAT number.

    If validation is enabled, though, when the first character of the VAT number is added, the fields are concealed again. I think it is an issue with jQuery. When I disable validation everything behaves correctly.

    I made a video to show you what happens. Here it is https://www.youtube.com/watch?v=fh3gyU0JHFY

  • Hi @nemoprofeta,

    Hmm… Could you please let me know how did you add that “Mi serve la fattura” checkbox? Via some plugin or with some custom JS code? If it’s a plugin – please let me know which one is it. And if it’s the code, maybe you could post the code here?

    Also – maybe you can tell me which our plugin’s previous version worked fine on your server, so I could check the changelog to find which changes could cause this.

    Thanks for your answer and sorry for the late reply. The checkout page has been customized through the functions.php file.

    Unfortunately I don’t know which one was the last working version.

    I paste below the whole functions.php file

    Hi @nemoprofeta,

    Thanks for the code. Please give me a day or two to analyze it. Will get back to you as soon as possible.

    Hi @nemoprofeta,

    I’ve checked the code and it seems that the problem is in lines 418-433. I’ve commented it and it started to work normally. By the way, this code also produces a lot of “Maximum call stack size exceeded” errors on your site (you can see that on your checkout page by clicking right mouse button, then “Inspect” and then “Console”). So I’ve commented this:

    
    /*
    // Intercetto i refresh del box PayPal e rimuovo il testo "Italian Indie"
    $("body").on('DOMSubtreeModified', "#payment", function() {
        $( "label[for='payment_method_paypal'] " ).html(function() {
            return $(this).html().replace('Italian Indie', '');
        });
    
        // Nascondo i campi facoltativi (dopo il caricamento asincrono)
        $( '#billing_company_field' ).hide();
        $( '#billing_country_field' ).hide();
        $( '#billing_address_1_field' ).hide();
        $( '#billing_address_2_field' ).hide();
        $( '#billing_postcode_field' ).hide();
        $( '#billing_city_field' ).hide();
        $( '#billing_state_field' ).hide();
        $( '#billing_eu_vat_number_field' ).hide();
    
    });
    */
    

    Now the only problem is that initially with “Mi serve la fattura” checkbox unchecked, other fields are still visible. To fix that I’ve added $( document ).ready( function() {} ) to lines 407-415, i.e.:

    
    // Nascondo i campi facoltativi (al caricamento della schermata)
    $( document ).ready( function() {
        $(".page-id-28651 #billing_company_field").hide();
        $('#billing_country_field').hide();
        $('#billing_address_1_field').hide();
        $('#billing_address_2_field').hide();
        $('#billing_postcode_field').hide();
        $('#billing_city_field').hide();
        $('#billing_state_field').hide();
        $('#billing_eu_vat_number_field').hide();
    } );
    

    Please take a look and let me know if it’s ok now.

    P.S. And if that will help and you like the plugin, please consider leaving me a rating.

    Thanks a lot. I’ll try soon!
