为什么图像上传失败php的is_uploaded_file检查？ [英] Why does image upload fail php's is_uploaded_file check?

问题描述

我有一个允许图片上传的html表单，但是上传的图片现在因为某种原因没有通过is_uploaded_file检查。

为什么上传失败is_uploaded_file检查？

HTML：

 < form enctype =multipart / form-dataid =RecipeAddFormmethod =post
 action =/ recipes / addaccept-charset =utf-8> 
 <！ -  ---省略标记 - > 
< input type =filename =data [Recipe] [image]value =id =RecipeImage/> 
 <！ -  ---省略标记 - > 
< / form> 
  

PHP：

  //返回false 
 echo is_uploaded_file（$ file ['tmp_name']）？'true'：'false'; 
  

我在$ file或$ _FILES数组上做了一个转储：

 数组
（
 [name] => add或remove.jpg 
 [type] => image / jpeg 
 [tmp_name] => E：\\xampp\\tmp\\phpB9CB.tmp 
 [error] => 0 
 [size] => 71869 
）
  

文件大小不是太大，错误是0。它是否会失败is_uploaded_file检查？

解决方案

可能是Windows的问题，因为它是区分大小写的，如果路径不匹配是不同的。尝试使用 realpath（$ file ['tmp_name']）

I have a html form that allows image uploads, but the image uploaded now fails the "is_uploaded_file" check for some reason.

So why does the upload fail the is_uploaded_file check?

HTML:

<form enctype="multipart/form-data" id="RecipeAddForm" method="post"
action="/recipes/add" accept-charset="utf-8">
    <!--- Omitted Markup -->
    <input type="file" name="data[Recipe][image]" value="" id="RecipeImage" />
    <!--- Omitted Markup -->
</form>

PHP:

// returns false
echo is_uploaded_file($file['tmp_name'])?'true':'false'; 

I did a dump on the $file or $_FILES array:

Array
(
    [name] => add or remove.jpg
    [type] => image/jpeg
    [tmp_name] => E:\\xampp\\tmp\\phpB9CB.tmp
    [error] => 0
    [size] => 71869
)

File size is not too large, and the error was 0. So why does it fail the is_uploaded_file check?

解决方案

Might be a problem with windows, since it's case sensitive and will not match if the path is different. Try using realpath($file['tmp_name'])
