我正在从fronted提交帖子，它有一些自定义字段。我使用ShortCodeAPI在任何页面/帖子中使用该表单。应在下面找到代码。但在提交表单后，什么都没有发生，表单返回。我需要你的帮助。

<?php
//Shortcode API
function apl_video(){
global $current_user;
get_currentuserinfo();
if (!isset($_POST[\'submit\'])) {

?>
<form name="new_post" method="post" action="">

        <tr><td><label for="vid_wid">Video Width</label></td><td><input id="vid_wid" tabindex="2" type="text" name="vid_wid"/></td></tr>
