PHP HTML FORM发送_POST数据，但不是_FILES [英] PHP HTML FORM sends _POST data but not _FILES

问题描述

表格：

 < form class =form-inlineaction =＃id =loginmethod =post> 
< input type =filename =fileid =file> 
< input type =hiddenname =testvalue =testy> 
< input class =btn btn-primary btn-blocktype =submitname =submitvalue =Go> 
< / form> 
  

testy 的值恰好，但没有_FILES上传后。

当我从一个页面发送到另一个页面时，这起作用，但由于我将它全部移到同一页面上，它不再有效。我缺少什么？

$ _ POST ['test'] shows testy < code $
$ b $ p $ $ FILES ['file'] 显示空白

解决方案

您的表单中需要 enctype =multipart / form-data属性：

 < form class =form-inlineaction =＃id =loginmethod =postenctype =multipart /表单数据> 
< input type =filename =fileid =file> 
< input type =hiddenname =testvalue =testy> 
< input class =btn btn-primary btn-blocktype =submitname =submitvalue =Go> 
< / form> 
  

I have a form that sends a file, yet it's not being able to be called after submit.

Form:

<form class="form-inline" action="#" id="login" method="post">
<input type="file" name="file" id="file">
<input type="hidden" name="test" value="testy"> 
<input class="btn btn-primary btn-block" type="submit" name="submit" value="Go">
</form>

The value of testy comes up just fine, but nothing from _FILES after it's uploaded.

This was working when I was sending from one page to another page, but since I moved it all to happen on the same page, it's no longer working. What am I missing?

$_POST['test'] shows testy

$_FILES['file'] shows empty

解决方案

You need enctype="multipart/form-data" attribute in your form:

<form class="form-inline" action="#" id="login" method="post" enctype="multipart/form-data">
<input type="file" name="file" id="file">
<input type="hidden" name="test" value="testy"> 
<input class="btn btn-primary btn-block" type="submit" name="submit" value="Go">
</form>
