我试图使用以下函数（在functions.php中）向购物车添加自定义价格：

//Change cart item price
function add_custom_price_callback( $cart_object ) {

$custom_price = intval($_POST[\'p_m\']);
$target_product_id = intval($_POST[\'s_o_v\']);         

foreach ( $cart_object->cart_contents as $value ) {

    //Single product
    if ( $value[\'product_id\'] == $target_product_id ) {
        $value[\'data\']->price = $custom_price;
    }
    //For variation
    if ( $value[\'variation_id\'] == $target_product_id ) {
        $value[\'data\']->price = $custom_price;
    }

}    
die();    
}

add\\u操作（“wp\\u ajax\\u add\\u custom\\u price”，“add\\u custom\\u price\\u callback”）；add\\u操作（“wp\\u ajax\\u nopriv\\u add\\u custom\\u price”，“add\\u custom\\u price\\u callback”）；add\\u操作（“woocommerce\\u before\\u calculate\\u totals”，“add\\u custom\\u price\\u callback”）；如果我对变量使用静态值，那么函数可以工作，但我需要通过Ajax调用动态设置变量。

我使用以下方法在“functions.php”中添加了Ajax：

//jQuery / Ajax on site
function site_scripts() {
    //jQ
    wp_enqueue_script( \'ww_site_script\', get_stylesheet_directory_uri() . \'/js/ww_site_script.js\', array( \'jquery\' ), null, true );
    //Ajax
     wp_localize_script( \'ww_site_script\', \'ajax_p\',
            array( \'ajax_url\' => admin_url( \'admin-ajax.php\' ) ) );

}
add_action( \'wp_enqueue_scripts\', \'site_scripts\' );

下面是我的Ajax调用：

//Send ajax values    
$( \'.single_add_to_cart_button\' ).click(function() {
    console.log(s_o_v); 
    console.log(p_m);

    var data = {
        action: \'add_custom_price\',
        p_m: p_m,
        s_o_v : s_o_v
    };

    $.post( ajax_p.ajax_url, data, function(response) {
        console.log( response );
    }, \'json\');
    });

“控制台日志（响应）；”获取在函数中回显但admin ajax返回0的值。如何将值发送到“add\\u custom\\u price\\u callback”函数？

function add_custom_price_callback() {
    $custom_price = intval($_POST[\'p_m\']);
    $target_product_id = intval($_POST[\'s_o_v\']);         

    foreach ( WC()->cart->get_cart() as $key=>$value ) {

        //Single product
        if ( $value[\'product_id\'] == $target_product_id ) {
             $value[\'data\']->set_price($custom_price);
        }
        //For variation
        if ( $value[\'variation_id\'] == $target_product_id ) {
             $value[\'data\']->set_price($custom_price);
        }
   }
   //to check if is work or not       
   wp_send_json(array($value[\'data\']->get_price($custom_price)));   
}
