多文件上传不起作用 [英] Multifile upload is not working
问题描述
我有以下的表单，用户可以选择要上传的文件。这部分是好的，多选择工作：
< form action =upload.phpmethod =post enctype =multipart / form-data>
< input type =filemultiple =multiplename =fileToUpload []id =fileToUpload>
< button type =submitclass =btn btn-primaryvalue =上传图片name =submit>书签文本< / button>
< / form>
以下是用于上传文件的php：
<？php
$ ID = uniqid（）;
mkdir（temp /。$ ID）;
$ target_dir =temp /;
$ target_file = $ target_dir。 /。 $ ID。 /。基名（$ _ FILES [ fileToUpload] [ 名称]）;
$ target = basename（$ target_file，。docx）;
$ uploadOk = 1;
$ imageFileType = pathinfo（$ target_file，PATHINFO_EXTENSION）;
//检查文件是否已经存在
//检查$ uploadOk设置为0是否有错误
if（$ uploadOk == 0）{
echoSorry，your文件没有上传。;
//如果一切正常，尝试上传文件
} else {
if（move_uploaded_file（$ _ FILES [fileToUpload] [tmp_name]，$ target_file））{
回显文件。 basename（$ _FILES [fileToUpload] [name]）。 已上传。
} else {
echo抱歉，上传文件时出现错误。
}
}
？>
我无法使代码正常工作。我尝试了许多不同的方法。我想我需要一个foreach而不是在哪里呢？如果我粘贴upload.php： die（'< pre>。print_r（$ _ FILES [ fileToUpload]，true）。'< / pre>'）; 在PHP的乞讨我得到以下内容：
<$ p数组
（
[name] =>数组
（
[0] => sablonTeszt20150805.docx
[1 ] => sablonTeszt20150805másolat.docx
[2] => sablonTeszt20150805másolat2.docx
）
[type] => Array

如果你想上传多个.docx文件，这是你可以做的。在每个关键步骤中，我都会添加注释，让您了解每一步所发生的事情。
$ b HTML $ b
< form action =index.phpmethod =postenctype =multipart / form-data>
< input type =filemultiple =multiplename =fileToUpload []id =fileToUpload>
< button type =submitclass =btn btn-primaryvalue =上传图片name =submit>书签文本< / button>
< / form>
PHP
< pre $ <？php
if（isset（$ _ POST ['submit']））{
$ ID = uniqid（）;
//文件模式：777
//为每个人读，写和执行
//你应该根据你的需求改变这个文件模式
mkdir（ temp。DIRECTORY_SEPARATOR。$ ID，0777，true）;
$ target_dir =temp。 DIRECTORY_SEPARATOR。 $ ID;
//计数上传的文件数量
$ num_of_files = count（$ _ FILES [fileToUpload] [name]）;
//通过每个文件循环上传
（$ i = 0; $ i <$ num_of_files; ++ $ i）{
$ target_file = $ target_dir。 DIRECTORY_SEPARATOR。基名（$ _ FILES [ fileToUpload] [ 名称] [$ I]）;
$ uploadOk = 1;
//获取文件扩展名
$ ext = strtolower（pathinfo（$ target_file，PATHINFO_EXTENSION））;
检查它是否是.docx文件
if（$ ext ==docx）{
//检查文件是否已经存在
//如果（$ uploadOk == 0）{
echo抱歉，您的文件没有上传，请检查$ uploadOk是否被错误设置为
。
//如果一切正常，尝试上传文件
} else {
if（move_uploaded_file（$ _ FILES [fileToUpload] [tmp_name] [$ i] ，$ target_file））{
echoThe file。基本名（$ _ FILES [ fileToUpload] [ 名称] [$ i]）。 已上传。
} else {
echo抱歉，上传文件时出现错误。
}
}
} else {
echo只允许.docx文件;
}
}
}

注意：为了提供跨平台兼容性，您应该使用PHP的 DIRECTORY_SEPARATOR 常量来写路径字符串，例如..。DIRECTORY_SEPARATOR。foo，因为在Windows上执行的方式是.. \foo../ foo。
I have the following form in which the user can select the files to upload. This part is okay, the multi-select is working:
<form action="upload.php" method="post" enctype="multipart/form-data">
<input type="file" multiple="multiple" name="fileToUpload[]" id="fileToUpload">
<button type="submit" class="btn btn-primary" value="Upload Image" name="submit">Fájlok feltöltése</button>
</form>
And the following php which is used to upload the files:
<?php
$ID = uniqid();
mkdir("temp/" . $ID);
$target_dir = "temp/" ;
$target_file = $target_dir . "/" . $ID . "/" . basename($_FILES["fileToUpload"]["name"]);
$target = basename($target_file,".docx");
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if file already exists
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
?>
I can,t make the code working. I tried many different ways. I suppose that I need a foreach somewhere but where? What am I doing wrong?
update: If I paste upload.php: die('<pre>'.print_r($_FILES["fileToUpload"], true).'</pre>'); at the begging of the php I get the following:
Array
(
[name] => Array
(
[0] => sablonTeszt20150805.docx
[1] => sablonTeszt20150805 másolat.docx
[2] => sablonTeszt20150805 másolat 2.docx
)
[type] => Array
(
[0] => application/vnd.openxmlformats-officedocument.wordprocessingml.document
[1] => application/vnd.openxmlformats-officedocument.wordprocessingml.document
[2] => application/vnd.openxmlformats-officedocument.wordprocessingml.document
)
[tmp_name] => Array
(
[0] => /Applications/MAMP/tmp/php/phpiu1FTX
[1] => /Applications/MAMP/tmp/php/phpHm4xiV
[2] => /Applications/MAMP/tmp/php/phpjKZV72

If you want to upload multiple .docx files, this is what you can do. At every critical step I added comments to make you understand what's happening at each step.
HTML
<form action="index.php" method="post" enctype="multipart/form-data">
<input type="file" multiple="multiple" name="fileToUpload[]" id="fileToUpload">
<button type="submit" class="btn btn-primary" value="Upload Image" name="submit">Fájlok feltöltése</button>
</form>
PHP
<?php
if(isset($_POST['submit'])){
$ID = uniqid();
// file mode: 777
// read, write and execute for everyone
// you should change this file mode based on your requirement
mkdir("temp" . DIRECTORY_SEPARATOR . $ID, 0777, true);
$target_dir = "temp" . DIRECTORY_SEPARATOR . $ID ;
// count the number of files uploaded
$num_of_files = count($_FILES["fileToUpload"]["name"]);
// loop through each file to upload
for($i = 0; $i < $num_of_files; ++$i){
$target_file = $target_dir . DIRECTORY_SEPARATOR . basename($_FILES["fileToUpload"]["name"][$i]);
$uploadOk = 1;
// get the file extension
$ext = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// check if it's a .docx file
if($ext == "docx"){
// Check if file already exists
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"][$i], $target_file)) {
echo "The file ". basename($_FILES["fileToUpload"]["name"][$i]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
}else{
echo "only .docx files are allowed";
}
}
}
?>
Sidenote: In order to provide cross-platform compatibility, you should use PHP's DIRECTORY_SEPARATOR constant to write path strings, e.g. "..".DIRECTORY_SEPARATOR."foo", because the way to do it on Windows would be "..\foo" while on everything else (Linux, UNIX, Mac OS X) it would be "../foo".
