上传多个文件到服务器和 [英] Upload multiple files to server and

问题描述

我的第一篇文章很温柔​​！我试过寻找这个，有很多类似的帖子，但我似乎无法找到任何完全像我的问题，我已经在这个小时！ ： - /

我使用PHP（5.3）和MySQL构建系统，部分功能是用户需要上传一些基于以前的文件选择。一个示例表格如下：

 < form action =method =postenctype =multipart / form-数据id =uploadFiles> 
< p> 
< label for =file1>上传档案1：< / label> 
< input type =filename =file1id =image> 
< / p> 
< p> 
< label for =file2>上传文件2：< / label> 
< input type =filename =file2id =image2> 
< / p> 
< p> 
< input type =submitname =uploadid =uploadvalue =Upload> 
< / p> 
< / form> 
  

在这个例子中，用户需要上传两个不同的文档。这一切都适用于我，我可以将2个文件保存到服务器，然后通过循环$ _FILES中的文件名，文件类型（pdf，jpg）和用户标识符等将2条记录插入数据库中的表中我的上传类。

然而我试图做的是以某种方式添加名称属性< input name =foo> ，以便文件1在名为document_type的列中具有file1，并且文件2将具有file2。这样我就可以在MySQL中做一个基本的检查，看看用户是否已经上传了相应的文件。

为了切入正题，是否有办法分配或关联我的Upload类中的$ _FILES中的每个文件都具有INPUTname属性，这样当我通过$ _FILES循环时，有一个唯一的document_type？

请让我知道您是否需要关于我的设置的更多信息。

  foreach（$ _FILES as $ inputName => $ uploadedFile）{
 echo $ inputName，'：'，PHP_EOL; 
 print_r（$ uploadedFile）; 
} 
  

输出

  file1：
数组（
'name'=> ... 
'tmp_name'=> ... 
 ... 
）
 file2：
数组（
'name'=> ... 
'tmp_name'=> ... 
 ... 
）
  

My first post so be gentle! I've tried searching for this and there are many similar posts, but I can't seem to find anything exactly like my problem and I have been at this for hours! :-/

I'm building a system in PHP (5.3) and MySQL and part of the functionality is that a user is required to upload some files based on some previous selections. An example form is as follows:

<form action="" method="post" enctype="multipart/form-data" id="uploadFiles">
<p>
<label for="file1">Upload file 1:</label>
<input type="file" name="file1" id="image">
</p>
<p>
<label for="file2">Upload file 2:</label>
<input type="file" name="file2" id="image2">
</p>
<p>
<input type="submit" name="upload" id="upload" value="Upload">
</p>
</form>

In this instance the user is required to upload two different documents. This all works for me and I can save the 2 files to the server and then insert 2 records to a table in the database with the file name, file type (pdf, jpg) and user id etc by looping through "$_FILES" in my Upload class.

What I am trying to do however is somehow add the name attribute <input name="foo"> to the inserted row so that "File 1" would have "file1" in a column called document_type and "File 2" would have "file2". That way I can do a basic check in MySQL to see if the user has uploaded the appropriate files.

To cut to the chase, is there a way to assign or associate the INPUT "name" attribute to each file in $_FILES in my Upload class so that when when I loop through $_FILES, there is a unique document_type?

Please let me know if you require further information regarding my setup.

解决方案

foreach ($_FILES as $inputName => $uploadedFile) {
    echo $inputName, ':', PHP_EOL;
    print_r($uploadedFile);
}

Output

file1:
Array (
    'name' => ...
    'tmp_name' => ...
    ...
)
file2:
Array (
    'name' => ...
    'tmp_name' => ...
    ...
)
