Remove Product in the Cart Widget Using AJAX

Remove Product in the Cart Widget Using AJAX

WooCommerce – one and the best extensions for building an online store with which I have worked, but like other extensions it is not ideal. In my projects, I tried to make it better and add useful features to make it even more user-friendly. In this article, we’ll talk about how to remove product in the shopping cart widget using AJAX.

You must change the mini-cart.php template and add the attribute data-cart_item_key to the deletion link


<?php echo apply_filters( 'woocommerce_cart_item_remove_link', sprintf(
    '<a href="%s" class="remove" aria-label="%s" data-product_id="%s" data-product_sku="%s" data-cart_item_key="%s">×</a>',
    esc_url( WC()->cart->get_remove_url( $cart_item_key ) ),
    esc_html__( 'Remove this item', 'deepsoul' ),
    esc_attr( $product_id ),
    esc_attr( $_product->get_sku() ),
    esc_attr( $cart_item_key )
), $cart_item_key ); ?>
If this is not done there will be problems when deleting variable products

Next, we need to add a click event to the product deletion link in the cart. This code should be added to the main JS file of your theme.


// Ajax delete product in the cart
$(document).on('click', '.mini_cart_item a.remove', function (e)
{
    e.preventDefault();

    var product_id = $(this).attr("data-product_id"),
        cart_item_key = $(this).attr("data-cart_item_key"),
        product_container = $(this).parents('.mini_cart_item');

    // Add loader
    product_container.block({
        message: null,
        overlayCSS: {
            cursor: 'none'
        }
    });

    $.ajax({
        type: 'POST',
        dataType: 'json',
        url: wc_add_to_cart_params.ajax_url,
        data: {
            action: "product_remove",
            product_id: product_id,
            cart_item_key: cart_item_key
        },
        success: function(response) {
            if ( ! response || response.error )
                return;

            var fragments = response.fragments;

            // Replace fragments
            if ( fragments ) {
                $.each( fragments, function( key, value ) {
                    $( key ).replaceWith( value );
                });
            }
        }
    });
});

Add action to functions.php file to handle AJAX request


// Remove product in the cart using ajax
function warp_ajax_product_remove()
{
    // Get mini cart
    ob_start();

    foreach (WC()->cart->get_cart() as $cart_item_key => $cart_item)
    {
        if($cart_item['product_id'] == $_POST['product_id'] && $cart_item_key == $_POST['cart_item_key'] )
        {
            WC()->cart->remove_cart_item($cart_item_key);
        }
    }

    WC()->cart->calculate_totals();
    WC()->cart->maybe_set_cart_cookies();

    woocommerce_mini_cart();

    $mini_cart = ob_get_clean();

    // Fragments and mini cart are returned
    $data = array(
        'fragments' => apply_filters( 'woocommerce_add_to_cart_fragments', array(
                'div.widget_shopping_cart_content' => '<div class="widget_shopping_cart_content">' . $mini_cart . '</div>'
            )
        ),
        'cart_hash' => apply_filters( 'woocommerce_add_to_cart_hash', WC()->cart->get_cart_for_session() ? md5( json_encode( WC()->cart->get_cart_for_session() ) ) : '', WC()->cart->get_cart_for_session() )
    );

    wp_send_json( $data );

    die();
}

add_action( 'wp_ajax_product_remove', 'warp_ajax_product_remove' );
add_action( 'wp_ajax_nopriv_product_remove', 'warp_ajax_product_remove' );

Do you want to see how it works?

    Thanks you very much for this but I have one question, from the cart page when I remove a product from de widget the product is removed from the widget but not from the cart product list and if I remove a product from the cart product list it remove the product from the widget.
    Is it possible to have both ways ?
    Hope you understand, thanks you again!)

      Thank you for your question.
      Yes, there is an easy way to do this. You need to add one line of code to the Ajax request.

      $( document.body ).trigger( 'wc_update_cart' );

      It should be something like this

      
      // Ajax delete product in the cart
      $(document).on('click', '.mini_cart_item a.remove', function (e)
      {
          e.preventDefault();
      
          var product_id = $(this).attr("data-product_id"),
              cart_item_key = $(this).attr("data-cart_item_key"),
              product_container = $(this).parents('.mini_cart_item');
      
          // Add loader
          product_container.block({
              message: null,
              overlayCSS: {
                  cursor: 'none'
              }
          });
      
          $.ajax({
              type: 'POST',
              dataType: 'json',
              url: wc_add_to_cart_params.ajax_url,
              data: {
                  action: "product_remove",
                  product_id: product_id,
                  cart_item_key: cart_item_key
              },
              success: function(response) {
                  if ( ! response || response.error )
                      return;
      
                  var fragments = response.fragments;
      
                  // Replace fragments
                  if ( fragments ) {
                      $.each( fragments, function( key, value ) {
                          $( key ).replaceWith( value );
                      });
                  }
             
                  // Update cart
                  $( document.body ).trigger( 'wc_update_cart' );
              }
          });
      });

    Getting this error on WC ver 3.4.3. Block is not a function. Please help.

    $(document).on("click", ".header-cart-item-img", function() {
        let imageBlock = $(this);
    
        $.ajax({
            url: `${cozastore.siteurl}?wc-ajax=remove_from_cart`,
            type: "post",
            data: {
                cart_item_key: imageBlock.data("cartitemkey")
            },
            dataType: "json",
            beforeSend: function () {
                imageBlock.closest("li").block({
                    message: null,
                    overlayCSS: {

                    }
                });
            },
            success: function(resp) {
                if ( ! resp || resp.error )
                    return;
    
                if( resp && resp.fragments ) {
                    $.each( resp.fragments, function( key, value ) {
                        $( key ).replaceWith( value );
                    });
                }
            }
        })
    });

      I think the problem is that this function inside the AJAX request is not available. You need to use it before the AJAX request and not inside using ‘beforeSend’

    Thanks for this code. I would like to make some modifications, but I am a total beginner in JS and AJAX. I added two functions to fade in/out the subtotal amount. Fade out is working fine, because I am calling it right after the click function. But I don’t know where I should put the fade in function. Can you help me with that?

    My functions:
    ` $.fade_out_subtotal = function(){

    $(‘.sidecart-subtotal-amount’).fadeOut(1000);
    }
    $.fade_in_subtotal = function(){

    setTimeout(function(){
    $(‘.sidecart-subtotal-amount’).fadeIn(1000);
    },1000);
    }
    `

      Hello Fabian,

      This is quite difficult to do.

      1. You need to add display:none for your cart counter of products in $fragments. This is code snippet works for me, but I don’t things that it will be work for you. You need change array key for your mini cart template

      $fragments['.tm_cart_widget .tm_cart_label .cart_ajax_data .total_products'] = '<div style="display:none">' . WC()->cart->get_cart_contents_count() . '</div>';

      2. In the $each that is responsible for replacing HTML, you need to add a check. If the key coincides with the number of items in the cart, we add fadeIn.

      if ( fragments ) {
          $.each( fragments, function( key, value ) {
              $( key ).replaceWith( value );
              if( key == '.tm_cart_widget .tm_cart_label .cart_ajax_data .total_products' ) {
                  $( key ).fadeIn(1000);
              }
          });
      }

      3. You also need to add a JS code to display the products count when you first load the page, and delete displat:none This is code snippet you need to insert beyond the click event.

      $( '.tm_cart_widget .tm_cart_label .cart_ajax_data .total_products' ).fadeIn(1000);

      I hope I was helpful 🙂
      Good luck, Alex

        Hi Alex,

        thanks for your reply. I couldn’t achieve what I wanted by following your answer. You were talking about the “WC()->cart->get_cart_contents_count()”. But I need “WC()->cart->get_cart_subtotal();”. Adding “style=display:none;” to my subtotal div didn’t work.

        I used my fade in/out functions and added them to your Ajax widget remove click function. It is working, but the subtotal amount doesn’t fade in nicely after I remove a product from the mini-cart. And if remove all products form the cart, you can see only the subtotal div for a second. After a second it disappears and the “cart is empty” message appears. Guess I need another function for that or the delays are too long.

        How do I post code in your comments? Here is my js code (unformatted):

        mini-cart part for subtotal:

        cart->get_cart_subtotal(); ?>

        JS code:
        $(document).on(‘click’, ‘.sidecart-item-remove’, function (e){

        $.fade_out_subtotal();
        e.preventDefault();

        var product_id = $(this).attr(“data-product_id”),
        cart_item_key = $(this).attr(“data-cart_item_key”);

        $.ajax({
        type: ‘POST’,
        dataType: ‘json’,
        url: wc_add_to_cart_params.ajax_url,
        data: {
        action: “product_remove”,
        product_id: product_id,
        cart_item_key: cart_item_key
        },

        beforeSend: function() {
        $(‘#sidecart-item-id-‘+cart_item_key).fadeOut(500);
        },

        success: function(response) {
        setTimeout(function(){
        if ( ! response || response.error )
        return;

        var fragments = response.fragments;

        // Replace fragments
        if ( fragments ) {
        $.each( fragments, function( key, value ) {
        $( key ).replaceWith( value );
        $.fade_in_subtotal();
        });
        }

        }, 500);

        // Update cart
        $( document.body ).trigger( ‘wc_update_cart’ );

        },

        complete: function(){
        console.log(‘Item removed from sidecart’);
        }
        });

        });

        /**
        * Fade in/out subtotal in sidecart
        */

        $.fade_out_subtotal = function(){
        $(‘.sidecart-subtotal-amount’).fadeOut(500);
        }
        $.fade_in_subtotal = function(){
        setTimeout(function(){
        $(‘.sidecart-subtotal-amount’).fadeIn(500);
        }, 500);
        }

        Regards

        Fabian

          All my comments are only recommendations, if I have an idea, I can voice it, but you should do the rest yourself.

          In similar cases, I never use setTimeout.

          If I want to change the value of something using fade, I am do of something like this

          $('.tm-wishlist-count').fadeOut( 500, function()
          {
              $(this).text("new count").fadeIn();
          });
