如何在Wordpress中用Ajax传递Javascript对象给PHP

var data = {
    name: 'John',
    age: 30,
    email: 'john@example.com'
};

$.ajax({
    url: ajax_object.ajax_url, // WordPress提供的Ajax URL
    type: 'POST',
    data: {
        action: 'my_ajax_handler', // 自定义的Ajax处理函数名
        data: JSON.stringify(data) // 将对象转换为JSON字符串
    },
    success: function(response) {
        console.log('Success:', response);
    },
    error: function(xhr, status, error) {
        console.log('Error:', error);
    }
});

add_action('wp_ajax_my_ajax_handler', 'my_ajax_handler');
add_action('wp_ajax_nopriv_my_ajax_handler', 'my_ajax_handler'); // 非登录用户处理

function my_ajax_handler() {
    $data = json_decode(file_get_contents('php://input'), true);
    
    // 处理接收到的数据
    $name = $data['name'];
    $age = $data['age'];
    $email = $data['email'];
    
    // 返回响应
    echo 'Received: Name=' . $name . ', Age=' . $age . ', Email=' . $email;
    
    wp_die(); // 结束Ajax调用
}

jQuery(document).ready(function($) {
    $.ajaxSetup({
        beforeSend: function(xhr, settings) {
            if (!/^(GET|HEAD|OPTIONS|TRACE)$/.test(settings.type) && !this.crossDomain) {
                xhr.setRequestHeader("X-Requested-With", "XMLHttpRequest");
            }
        }
    });
});
