Trigger a JQuery click once product is added to cart on WooCommerce single products

Question

I was trying to make a sidebar using mini-cart.php on woocommerce and so far im doing okay, but i wanted to trigger the sidebar after i click on "add to cart" button on page product.

I found Run javascript code after ajax add to cart event in Woocommerce answer and I made some changes to the code:

add_action( 'wp_footer', 'trigger_for_ajax_add_to_cart' );
 function trigger_for_ajax_add_to_cart() {
 ?>
    <script type="text/javascript">
        (function($){
            $('body').on( 'click', '.single_add_to_cart_button', function(){
                $( ".open-side-cart" ).trigger( "click" );
            });
        })(jQuery);
    </script>
 <?php
}

What I want is to trigger the mini-cart.php sidebar when the user clicks on the ".single_add_to_cart_button" class button, and it works. But as woocommerce reloads the page updating the mini-cart.php , so the trigger works before reloading the page.

Is there a way to trigger after reloading the page?

Answer 1

As you are not using Ajax add to cart, when product is added to cart the page reloads as product data is posted… Then you can check for $_POST['add-to-cart'] to display the active part of your jQuery script, once the page is reloaded as follows:

add_action( 'wp_footer', 'trigger_for_ajax_add_to_cart' );
function trigger_for_ajax_add_to_cart() {
    if ( isset($_POST['add-to-cart']) && $_POST['add-to-cart'] > 0
    && isset($_POST['quantity']) && $_POST['quantity'] > 0 ) :
    ?>
    <script type="text/javascript">
        (function($){
            $( ".open-side-cart" ).trigger( "click" );

            // Display an alert for testing purpose (To be removed)
            alert('".open-side-cart" Click!');
        })(jQuery);
    </script>
    <?php
    endif;
}

Code goes in functions.php file of the active child theme (or active theme). Tested and works.

In some cases you may need to add a delay, so in this case you can replace:

        $( ".open-side-cart" ).trigger( "click" );

by the following code block:

        setTimeout(function(){
            $( ".open-side-cart" ).trigger( "click" );
        }, 500);

Thanks @LoicTheAztec I found an solution.

In my case I was unable to trigger jQuery using $ _POST ['add-to-cart'] .

My solution was to use an alternative method, every time a product is added to the cart a message appears and says "(product name) added to the cart" the text appears inside a div with the class .woocommerce-message .

using this method i created a trigger for every time this message appears will click on the class .open-side-cart and the side cart will appear

The code:

add_action( 'wp_footer', 'trigger_for_ajax_add_to_cart' );

function trigger_for_ajax_add_to_cart() {
    //Only trigger if is single product page
    if ( is_product() )  {
    ?>
            <script type="text/javascript">
                (function($){
                        //If .woocommerce-message is visible
                        $(".woocommerce-message").each(function() {
                                if ($(this).css("visibility") == "visible") {

                                    //Trigger side cart .open-side-cart
                                    setTimeout(function(){
                                        $( ".open-side-cart" ).click();
                                    }, 500);

                                    //Nothing Happen
                                } else {
                                        return false;
                                }
                        });
                })(jQuery);
            </script>
    <?php
    }
}
