HTML 5 multi file upload with PHP
提问by kylex
Here is the code I have, and I'm wondering what I'm doing wrong that it doesn't display the name.
这是我的代码，我想知道我做错了什么，它没有显示名称。
<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:
以及不起作用的处理信息：
foreach ($_FILES['imageURL'] as $files[]) {
echo $files['file'];
}
Edit:
编辑：
When changing my foreach loop to:
将我的 foreach 循环更改为：
foreach ($_FILES['imageURL'] as $file) {
echo $file['name'];
}
Still nothing prints out.
仍然没有打印出来。
However, when I do something like this:
但是，当我做这样的事情时：
foreach ($_FILES['imageURL']['name'] as $filename) {
echo $filename;
}
The filename does print. I don't know what that implies though.
文件名确实打印。我不知道这意味着什么。
SOLVED UPDATE:
解决更新：
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.
正如 John Conde 所链接的，上传多个文件时的数组交错结构与上传单个文件时的不同。要使用 foreach，我们必须重构数组。
$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;
NOW we can use foreach to loop:
现在我们可以使用 foreach 来循环：
foreach ($files as $file) {
echo $file['name'];
}

Instead of using for() and recounting the number of items in the array, you can use a more elegant foreach()
您可以使用更优雅的 foreach()，而不是使用 for() 并重新计算数组中的项目数
$files=array();
$fdata=$_FILES['file'];
if(is_array($fdata['name'])){
foreach ($fdata['name'] as $i => $d) {
$files[] = array(
'name' => $d,
'tmp_name' => $fdata['tmp_name'][$i]
);
}
}
else $files[]=$fdata;

Maybe I'm wrong, but wouldn't setting multiple=""turn multiple uploads off? Just use multipleby itself, as shown in the HTML5 specor, for XHTML compatibility, multiple="multiple":
也许我错了，但是设置不会multiple=""关闭多个上传吗？只需单独使用multiple，如HTML5 规范中所示，或者，对于 XHTML 兼容性，multiple="multiple"：
<input type="file" name="imageURL[]" id="imageURL" multiple />
