在cake php中获取上传文件的扩展名 [英] get extension of uploaded file in cake php

问题描述

我使用的是cakephp 2.1，我正在尝试上传文件，以及如何获取文件的扩展名。

I am using cakephp 2.1 and i am trying to upload files and how can i retrive the extension of the file.

Id Auto_Increment
username
file_name

Controller / UsersController.php

Controller/UsersController.php

public function register(){
            if ($this->request->is('post')){
                $filename = $this->data['User']['file_name']['name'];
                //$temp_ext = $this->data['User']['resume_file']['ext'];

                $this->Session->setFlash('Extension : ' . $temp_ext);
            }
}

尝试上述代码时，它只给出单个字母像L，r即firt字符的文件名，但不是扩展

When tried the above code, to get extension. it only gives single letters like L, r ie firt character of the filename but not extension

现在如何获得文件的扩展名..我通过这个链接

Now how can i get the extension of the file.. i gone through this link

http://api.cakephp.org/class/file

但无法检索该文件。

向@Julian Hollmann添加调试报告

array(
    'User' => array(
        'file_name' => array(
            'name' => '550992_234300256686731_213914803_n.jpg',
            'type' => 'image/jpeg',
            'tmp_name' => 'D:\xampp\tmp\php866F.tmp',
            'error' => (int) 0,
            'size' => (int) 42292
        )
    )
)

推荐答案

首先，您的数据应在 $ this-> request-> data

如果你想看看里面有什么，只需要 debug（$ this-> request-> data）;

If you want to see what's in there, just do debug($this->request->data);

编辑：
正确的答案是：

The correct answer is:

$filename = $this->request->data['User']['file_name']['name'];
$extension = pathinfo($filename, PATHINFO_EXTENSION);
