我有一个表格，填写后会上传 2 个文件(一个是 doc、docx 或 pdf，另一个是图像文件)。我的 Controller 验证表单 ok 并将文件上传到服务器。我的问题似乎是访问上传文件的数组!？

我在表单中的一个名为 $uploaded 的变量中引用了该数组，从错误看来，实际数组似乎被称为“成功”(我认为它是从 upload.php 库中获取这个名称的)我认为然后这包含 2 个元素，称为 [0] 和 [1]，每个元素包含另一个文件属性数组。

我基本上是在兜圈子，试图将这两个文件附加到电子邮件中。我希望有人能够帮助新手？我将 Controller 代码放在下面，如果您需要任何其他代码，请告诉我。

编辑:我更新了下面的代码 我现在取得了一些成功(不多):for 循环现在附加了 1 个文件，但是附加了两次。所以要么我的代码没有正确索引数组，要么数组没有存储两个文件信息？

<?php

最佳答案

最终在 google 的帮助下解决了这个问题:

$uploaded = $this->upload->up(FALSE); //Pass true if you want to create the index.php files
        var_dump($uploaded); 
        $data = array('uploaded_data');

        //Attach the 2 files to email
        foreach($_FILES as $key => $value){
            //var_dump($uploaded['success'][$key]['full_path']); //FOR TESTING
            $file = $uploaded['success'][$key]['full_path'];
            $this->email->attach($file);
            //unlink($file);
        }
