我目前有一个在数据库中创建项目的表单，然后在下一步中，它允许用户为该列表上传多个图像。这两个部分都单独工作，但我需要能够将第一页的$cid插入图像上传的查询中，以确定它对应于哪个列表
这是允许用户上传多个图像的页面
<?php require_once 'config.php';
// Start the session
session_start();
// Require the classes for the page
require_once '../../assets/imageClass.php';
// create a new object class
$objects = new imageClass();
// set page variables
$path = '../';
$title = 'image upload';
$replace = 'content';
$message = '';
// Connect to the database
if(isset($_POST['image_upload'])){
// Filter all of the $_POST data
$objects->filterEverything($_POST);
// Declare shorthand for the id value if there is $_POST data
$cid = $objects->clean['cid'];
}
else{
// Filter all of the $_GET data
$objects->filterEverything($_GET);
// Declare shorthand for the id value if there is $_GET data
$cid = $objects->clean['cid'];
}
?>

这是的上传功能

希望这能有所帮助。
请在每个文件的顶部使用摘录（$_REQUEST）。此函数将变量发布并获取到全局变量，如果包含该文件或调用另一个文件，则可以使用这些全局变量。然后回声$cid。
对于插入函数使用了这个。
$sql="INSERT INTO images (`id`,`listing`,`original_image`,`thumbnail_image`,`ip_address`) VALUES (NULL, $cid, '$name', '$thumbnail', '$ip');";
mysql_query($sql);
