在HTML表单上传过滤器扩展 [英] Filter Extensions in HTML form upload

问题描述

我有一个简单的HTML上传表单，我想指定一个默认的扩展名（例如* .drp）。我读过这样做的方式是通过输入标签的ACCEPT属性，但我不知道如何。

 < form enctype =multipart / form-dataaction =uploader.phpmethod =POST> 
 Upload DRP File：
< input name =Upload Saved Replaytype =fileaccept =*。drp/>< br /> 
< input type =submitvalue =Upload File/> 
< / form> 
  

编辑
我知道验证可以使用javascript，我希望用户只能在弹出的对话框中看到.drp文件。另外，我对这个应用程序中的服务器端验证并不在意。 对于像你这样的特定格式， 。你可以直接在accept =。drp中传递它，它可以工作。

但没有*

I have a simple HTML upload form, and I want to specify a default extension ("*.drp" for example). I've read that the way to do this is through the ACCEPT attribute of the input tag, but I don't know how exactly.

<form enctype="multipart/form-data" action="uploader.php" method="POST">
Upload DRP File:
<input name="Upload Saved Replay" type="file" accept="*.drp"/><br />
<input type="submit" value="Upload File" />
</form>

Edit I know validation is possible using javascript, but I would like the user to only see ".drp" files in his popup dialog. Also, I don't care much about server-side validation in this application.

解决方案

For specific formats like yours ".drp ". You can directly pass that in accept=".drp" it will work for that.

But without " * "

<input name="Upload Saved Replay" type="file" accept=".drp" />
<br/>
