我在结账页面中为产品添加了删除按钮。

代码-

function add_delete( $product_title, $cart_item, $cart_item_key ) {

    if (  is_checkout() ) {
        /* Get Cart of the user */
        $cart     = WC()->cart->get_cart();
        foreach ( $cart as $cart_key => $cart_value ){
           if ( $cart_key == $cart_item_key ){
                $product_id = $cart_item[\'product_id\'];
                $_product   = $cart_item[\'data\'] ;

                /*Add delete icon */
                $return_value = sprintf(
                  \'<a href="%s" class="remove" title="%s" data-product_id="%s" data-product_sku="%s" data-cart_item_key="%s">&times;</a>\',
                  esc_url( WC()->cart->get_remove_url( $cart_key ) ),
                  __( \'Remove this item\', \'woocommerce\' ),
                  esc_attr( $product_id ),
                  esc_attr( $_product->get_sku() ),
                  esc_attr( $cart_item_key )
                );

                /* Add product name */
                $return_value .= \'&nbsp; <span class = "product_name" >\' . $product_title . \'</span>\' ;

                return $return_value;
            }
        }
    }else{

        $_product   = $cart_item[\'data\'] ;
        $product_permalink = $_product->is_visible() ? $_product->get_permalink( $cart_item ) : \'\';
        if ( ! $product_permalink ) {
            $return_value = $_product->get_title() . \'&nbsp;\';
        } else {
            $return_value = sprintf( \'<a href="%s">%s</a>\', esc_url( $product_permalink ), $_product->get_title());
        }
        return $return_value;
    }

}
add_filter (\'woocommerce_cart_item_name\', \'add_delete\' , 10, 3 );

它工作得很好。但它刷新整个页面以删除产品，这与购物车页面不同。

Cart页面使用ajax删除产品。我也在尝试做同样的事情。但是，问题是我对Ajax知之甚少。

这是我试过的。

JavaScript

jQuery(document).ready(function($){

$(document).on(\'click\', \'tr.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(\'.shop_table\');

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

    $.ajax({
        type: \'POST\',
        dataType: \'json\',
        url: wc_checkout_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 );
                });
            }
        }
    });
});

});

还有PHP

function warp_ajax_product_remove()
{
    // Get order review fragment
    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_order_review();
    $woocommerce_order_review = ob_get_clean();
}

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

它会删除产品，但不会更新签出页面。

你们能帮帮我吗？非常感谢。

$.ajax({
    type: \'POST\',
    dataType: \'json\',
    url: wc_checkout_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 );
            });
        }
        jQuery(\'body\').trigger(\'update_checkout\');
    }
});

   jQuery( function($){
    if (typeof woocommerce_params === \'undefined\')
        return false;

    console.log(\'defined\');
