    Add Invisible reCaptcha v2 to PROD page for AJAX Add to Cart Form

    We get a lot of bot activity spamming our PROD page attributes which creates carts with spammy links and information.

    So, to combat that, I would like to add the invisible recaptcha v2 to our PROD page for the Add to Cart form.

    We are on the most current update for Miva running the Suivant ReadyTheme.

    Here is what I have done so far using google's guide and some other more generic online guides:

    Code Added to Head Tag:

    Code:
        <script type="text/javascript">
            var onSubmit = function(response) {
                document.getElementById("js-purchase-product").submit(); // send response to your backend service
            };
        </script>
    Code for Add to Cart Form:

    Code:
            <form method="post" action="&mvte:urls:BASK:auto;" name="add" id="js-purchase-product">
                <input type="hidden" name="Old_Screen" value="&mvte:global:Screen;" />
                <input type="hidden" name="Old_Search" value="&mvte:global:Search;" />
                <input type="hidden" name="Action" value="ADPR" />
                <input type="hidden" name="Product_Code" value="&mvte:product:code;" />
                <input type="hidden" name="Category_Code" value="&mvte:global:category_code;" />
                <input type="hidden" name="Offset" value="&mvte:global:Offset;" />

                    e.stopImmediatePropagation();
                    e.preventDefault();
    
                });
    
            };
    
            var addToCart = new addToCart;

    The trouble I am having is:


    Where do I add grecaptcha.execute();?


    I want to keep the functionality of the AJAX Add to Cart and Form Validation.


    Here is a link to a product page for reference: https://www.loveisarose.com/ILYR11.html



    Thanks in advance for any help or light shed on the situation.

    I'd think the most obvious point would be at the start. And if not true, just fail silently.

      I'm not really familiar with adding reCaptcha, however if you need that function to run prior to the submit, I would modify the add to cart function to be onSubmit of the form and add the execute call as an onClick of the button.

        Okay. Thanks guys.

        I would prefer it to run after everything is validated.

        That way the reCaptcha is only executed if all the required attributes are filled out or selected.

        Would that be a similar situation as you suggested Matt?

            Okay.

            Do i also need to change the add to cart button html to onsubmit? or just the function in the Scripts.js file?

            Code:
                                <span onclick="document.forms.add.action = '&mvtj:urls:BASK:auto;'; document.forms.add.elements.Action.value = 'ADPR';">
                                    <input type="submit" value="Add to Cart" data-value="Add to Cart" id="js-add-to-cart" class="button button-block corners uppercase add-to-cart black bg-sky bold" />
                                </span>

              I would append to the button's onClick call.

                I think this is a bit out of my skill set to get working properly.

                Even if I did get it to work, I just realized that if a user has javascript disabled, then they won't be able to add products to the cart. Can't seem to find a current noscript fallback.

                This makes me want to remove reCaptcha for our checkout as well.

                Somehow we still have lots of users with javascript disabled.

                Which is why we have noscript fallbacks all over our site.

                I guess we will have to deal with the bot spam.

                Or perhaps add a hidden field that won't allow forms to submit if it is filled out by a bot.

                Thanks for the help anyways though.

                Appreciate it.
