如何过滤WordPress的数据列表

function custom_filter() {
    global $typenow;
    global $wp_query;
        if ( $typenow == \'invitation_code\' ) { // Your custom post type slug
        $plugins = array( \'Searh-By-dealer-role\', \'Searh-By-distributer-role\',\'Used code\',\'availabel code\'); // Options for the filter select field
        $current_plugin = \'\';
        if( isset( $_GET[\'slug\'] ) ) {
            $current_plugin = $_GET[\'slug\']; // Check if option has been selected
        } ?>
        <select name="slug" id="slug">
            <option value="all" <?php selected( \'all\', $current_plugin ); ?>><?php _e( \'All\', \'wisdom-plugin\' ); ?></option>
            <?php foreach( $plugins as $key=>$value ) { ?>
            <option value="<?php echo esc_attr( $key ); ?>" <?php selected( $key, $current_plugin ); ?>><?php echo esc_attr( $value ); ?></option>
            <?php } ?>
        </select>
    <?php }
    }

    function custom_filter_data_by_slug( $query ) {
    global $pagenow;
    global $wpdb;
    // Get the post type
    $post_type = isset( $_GET[\'post_type\'] ) ? $_GET[\'post_type\'] : \'\';

    if ( is_admin() && $pagenow==\'edit.php\' && $post_type == \'invitation_code\' && isset( $_GET[\'slug\'] ) && $_GET[\'slug\'] !=\'all\' ) {

        if($_GET[\'slug\'] == "0")//search by dealer
        {
            $query->query_vars[\'meta_key\'] = \'userrole\';
            $query->query_vars[\'meta_value\'] = \'dealer\';



        }
        elseif($_GET[\'slug\']== "1")//search by distributer
        {
            $query->query_vars[\'meta_key\'] = \'userrole\';
            $query->query_vars[\'meta_value\'] = \'distributors\';


        }
        elseif($_GET[\'slug\']== "2")//used code
        {

            $query->query_vars[\'meta_key\'] = \'userlimit\';
            $query->query_vars[\'meta_value\'] = \'0\';

        }
        elseif($_GET[\'slug\']== "3")
        {
            //add_filter(\'posts_where\',\'data_where\',10,2);
            //below code not working

            $sql12 = "SELECT * FROM wp_posts WHERE ID IN(SELECT post_id FROM wp_postmeta WHERE meta_key=\'userlimit\' and meta_value > 0)";
            $results = $wpdb->get_results($sql12);
            return $results;


        }

    }
    }



}


$this->loader->add_action( \'restrict_manage_posts\', $plugin_admin, \'custom_filter\' );
$this->loader->add_filter(\'parse_query\',$plugin_admin,\'custom_filter_data_by_slug\');

使用此挂钩

但是用slug==3编写的代码不起作用。。

Apply_Filters(‘the_content’)-是否使其忽略快捷代码？

我正在使用apply_filters(\'the_content) 因此，我可以在后端的wp编辑器中看到格式正确的内容。但是，这也会呈现内容中的短代码。我希望它忽略短代码，对其余内容进行过滤，基本上与发帖时一样。如果您在后端查看帖子内容，您将看到短代码，但如果您在网站的页面内查看它，您将看到呈现的短代码（其结果）。这可能吗？
