大家好，我在使用Ajax过滤自定义帖子类型“资源”时遇到问题。我试图通过两种分类法过滤帖子，然后在提交按钮上的单击事件上激活Ajax调用。我不断收到“0”响应，但不确定我遗漏了什么。如果有人能帮助我，我将不胜感激！干杯，桑尼

以下是我的jQuery：

    function filterResources(){
        var the_topic_filter = $(\'#the_topic_selecter\').val();
        var the_resourcetype_filter = $(\'#the_resourcetype_selecter\').val();

        $(\'#results\').html(\'\');
        $(\'#results\').html(\'<tr><td colspan="5" class="thinking"><img src="/wp-content/themes/limenetwork/images/ajax-spinner.gif" /></td></tr>\');

        // AJAX CALL
        var data = {
            action: \'resourcehub_filter\',
            send_the_topic_filter : the_topic_filter,
            send_the_resourcetype_filter : the_resourcetype_filter,
        };

        // RESPONSE
        jQuery.post(ajaxurl, data, function(response) {
            $(\'#results\').html(\'\');
            $(\'#results\').html(response);

            if(!$.trim(response)){
                $(\'#results\').html(\'<tr><td colspan="5" class="thinking">We could not find any resources, please try again.</td></tr>\');
            }

        });

    }

// RESOURCE HUB FILTER

add_action( \'wp_ajax_resourcehub_filter\', \'resourcehub_filters\' );
add_action( \'wp_ajax_nopriv_resourcehub_filter\', \'resourcehub_filter\' );

function resourcehub_filter() {

    // GET VARS

    $the_topic_filter = $_POST[\'send_the_topic_filter\'];
    $the_resourcetype_filter = $_POST[\'send_the_resourcetype_filter\'];

    // LOOP ALL RESOURCES  (filter)
    global $post;

    // FOR NO FILTERS SELECTED

    if( $the_topic_filter == "" && $the_resourcetype_filter == ""){

        $args = array(
            \'post_type\' => \'resource\',
            \'post_status\' => \'publish\',
