上传时，$ _FILES为空 [英] $_FILES Empty When Uploading

问题描述

在尝试访问 $ _ FILES 数组时，PHP返回错误

When trying to access the $_FILES array, PHP returns the error

Undefined index：picture。

"Undefined index: picture".

在我的 php.ini 文件，文件上传已打开，任何用户都可以在 / tmp 目录中写入。在HTML表单中，enctype被设置为multipart / form-data。有趣的是，上传文件的基本名称打印出来，所以我相信PHP实际上已经看到了该文件，但上传它的一些问题。
有人可以就这个问题的潜在解决方案提供建议吗？顺便说一下，我使用的是PHP5。

In my php.ini file, File Uploads are turned on, and any user can write in the /tmp directory. In the HTML form, enctype is set to "multipart/form-data". Interestingly enough, the basename for the uploaded file prints so I believe that PHP has actually seen the file, but has some problem uploading it. Can someone provides suggestions on potential solutions to this problem? By the way, I am using PHP5.

PHP文件片段

Snippets from PHP File

echo "Picture=" . $_POST['picture'] . "<br/>";
$uploadedPic = $_FILES['picture']['tmp_name'];

HTML表单

<form action="PHPFile.php" method="post" enctype="multipart/form-data">

<p> Picture </p>
<input type = "file" id="picture" name="picture"/>

</form>

推荐答案

如果它是 $ _ POST ['picture'] ，那么它的逻辑，你不会在 $ _ POST中找到上传的文件数据，它位于 $ _ FILES

On what line do you get that warning? If it is the one with $_POST['picture'], then its logical, you wont find uploaded file data in $_POST, it is in $_FILES
