我正在使用“jquery file upload”脚本。上传照片时，此脚本适用于“UploadHandler.php”。我的问题是，如何将发送/获取变量发送到UploadHandler.php？
这是我的index.php代码：

文件server / php / index.php获取变量，然后你可以将它传递给UploadHandler.php类。
或者您可以直接从UploadHandler.php文件中使用它，但请记住，您必须将其作为全局变量。

这就是我最终在CodeIgniter中执行此操作的方法，您可以使用require（）执行相同的操作：
$params = array("id" => $id, "type" => $type);
$this->load->library('UploadHandler.php', $params);
Kevin B的文档链接可能会提供更好的方法来实现这一目标。
答案 2 :(得分：0)
这个解决方案适用于我，
index.php中的
<?php
session_start();
$_SESSION['passData'] = 'Data';
$passData = $_SESSION['passData'] ;
