这应该行得通。这是当你点击bookbarklet时，press this获取帖子id的方式。

add_action( \'load-post-new.php\', \'prefix_save_it\' );
function prefix_save_it() {
    // define some basic variables
    $quick = array();
    $quick[\'post_status\'] = \'draft\'; // set as draft first
    $quick[\'post_category\'] = isset($_POST[\'post_category\']) ? $_POST[\'post_category\'] : null;
    $quick[\'tax_input\'] = isset($_POST[\'tax_input\']) ? $_POST[\'tax_input\'] : null;
    $quick[\'post_title\'] = isset($_POST[\'post_title\'] ? $_POST[\'title\'] : null;
    $quick[\'post_content\'] = isset($_POST[\'post_content\']) ? $_POST[\'post_content\'] : null;

    // insert the post with nothing in it, to get an ID
    $post_ID = wp_insert_post($quick, true);
    if ( is_wp_error($post_ID) )
        wp_die($post_ID);

        $quick[\'ID\'] = $post_ID;
        wp_update_post($quick);
    }
    return $post_ID;
}
