用PHP上传HTML 5多文件 [英] HTML 5 multi file upload with PHP

问题描述

这是我的代码，我想知道我做错了它没有显示名称。

 < form action =self.phpmethod =postenctype =multipart / form-data> 
< input type =filename =imageURL []id =imageURLmultiple =/> 
< input type =submitvalue =submitname =submit/> 
< / form> 
  

处理信息不起作用：

  foreach（$ _FILES ['imageURL'] as $ files []）{
 echo $ files ['file']; 
 
  

编辑：

将我的foreach循环更改为：

  foreach（$ _FILES ['imageURL'] as $文件）{
 echo $ file ['name']; 
} 
  

仍然没有打印出来。

然而，当我做这样的事情时：

  foreach（$ _FILES ['imageURL'] ['name' ] as $ filename）{
 echo $ filename; 
} 
  

文件名不会打印。我不知道这意味着什么。

已解决更新：

由John Conde链接，上传多个文件时的阵列交错结构与上传单个文件时不同。要使用foreach，我们必须重组数组。

  $ files = array（）; 
 $ fdata = $ _ FILES ['imageURL']; 
 if（is_array（$ fdata ['name']））{
 for（$ i = 0; $ i< count（$ fdata ['name']）; ++ $ i）{
 $ files [] = array（
'name'=> $ fdata ['name'] [$ i]，
'type'=> $ fdata ['type'] [ $ i]，
'tmp_name'=> $ fdata ['tmp_name'] [$ i]，
'error'=> $ fdata ['error'] [$ i]，
'size'=> $ fdata ['size'] [$ i] 
）; 
} 
} else $ files [] = $ fdata; 
  

现在我们可以使用foreach循环：

  foreach（$ files as $ file）{
 echo $ file ['name']; 
} 
  

解决方案

试用

  foreach（$ _FILES ['imageURL'] as $ file）{
 echo $ file ['name']; 
}

Here is the code I have, and I'm wondering what I'm doing wrong that it doesn't display the name.

<form action = "self.php" method="post" enctype="multipart/form-data">
<input type="file" name="imageURL[]" id="imageURL" multiple="" />
<input type="submit" value="submit" name="submit" />
</form>

And the processing info that isn't working:

foreach ($_FILES['imageURL'] as $files[]) { 
    echo $files['file'];
}

Edit:

When changing my foreach loop to:

foreach ($_FILES['imageURL'] as $file) { 
    echo $file['name'];
}

Still nothing prints out.

However, when I do something like this:

foreach ($_FILES['imageURL']['name'] as $filename) { 
    echo $filename;
}

The filename does print. I don't know what that implies though.

SOLVED UPDATE:

As linked to by John Conde, the array interlace structure is different when uploading multiple files than when uploading a single file. To use foreach, we must restructure the array.

$files=array();
$fdata=$_FILES['imageURL'];
if(is_array($fdata['name'])){
for($i=0;$i<count($fdata['name']);++$i){
        $files[]=array(
    'name'    =>$fdata['name'][$i],
    'type'  => $fdata['type'][$i],
    'tmp_name'=>$fdata['tmp_name'][$i],
    'error' => $fdata['error'][$i], 
    'size'  => $fdata['size'][$i]  
    );
    }
}else $files[]=$fdata;

NOW we can use foreach to loop:

foreach ($files as $file) { 
    echo $file['name'];
}

解决方案

Try

foreach ($_FILES['imageURL'] as $file) { 
    echo $file['name'];
}
