我的代码有什么问题？它不获取计数，但正在插入数据库。

function r_rate_recipe()
{
    global $wpdb;
    $output = array(\'status\' => 1);
    $post_id = absint($_POST[\'rid\']);
    $rating = round($_POST[\'rating\'], 1);
    $user_ip = $_SERVER[\'REMOTE_ADDR\'];

    $rating_count = $wpdb->get_var(
        "SELECT COUNT(*) FROM \'" . $wpdb->prefix . "racipe_ratings\'
            WHERE recipe_id=\'" . $post_id . "\' AND user_ip=\'" . $user_ip . "\'"
    );


    if ($rating_count > 0) {
        wp_send_json($output);
    }


    $wpdb->insert(
        $wpdb->prefix . \'racipe_ratings\',
        array(
            \'recipe_id\' => $post_id,
            \'rating\' => $rating,
            \'user_ip\' => $user_ip
        ),
        array(\'%d\', \'%f\', \'%s\')
    );
    $output[\'status\'] = 2;
    wp_send_json($output);
}
