我的网站上有一个表单，可以从前端创建帖子。因此，每次刷新页面时，我都会首先收到以下消息：

您正在查找输入的已用信息的页面。返回该页面可能会导致重复您所做的任何操作。是否要继续？

若页面被刷新，则会执行上一个操作，即创建具有与上一个帖子中相同条目的帖子。代码为：

<form action="" method="post" name="story_form" onsubmit="return vedioform()"  enctype="multipart/form-data">
    <label>Add link to your video</label><br />
    <input type="text" class="input-big" name="cntnt"/>                                       
    <label>Name</label><br />
    <input type="text" class="input-box" name="fname" />                
    <label>Email</label><br />
    <input type="text" class="input-box" name="email"  />
    <label>Your Wix website</label><br />
    <input type="text" class="input-box" name="title"/>
    Excerpt::<input type="text" class="input-box" name="excerpt"/>
    custom:::<input type="text" class="input-box" name="custom"/>
    <label>Your picture (Type: jpeg, jpg, png, gif)</label><br />
    <input type="file" size="60" id="BrowserHidden" onchange="getElementById(\'FileField\').value = getElementById(\'BrowserHidden\').value;" name="thumbnail"/>
    <input type="text" id="FileField" name="filefield" />
    <input type="submit"  class="form-submit" id="submit" value="SUBMIT" name="submit-video"/><br />
</form>

<?php
$title = $_POST[\'title\']; //from your form...
$content=$_POST[\'cntnt\'];
$excerpt=$_POST[\'excerpt\'];
$custom = $_POST[\'custom\'];
//-- Set up post values
$myPost = array(
    \'ID\' => \'\',
    \'post_title\' => $excerpt,
    \'post_excerpt\' => $excerpt,
    \'post_status\' => \'publish\',
    \'post_type\' => \'post\',
    \'post_author\' => $authorID,
    \'post_content\' =>$content,
    \'comment_status\' => \'closed\',
    \'ping_status\' => \'closed\',          
    \'post_category\' => array(\'7\'),
);

$new_post = wp_insert_post( $myPost);
add_post_meta($new_post, \'rating\', $custom, true);
?>
