在php中多文件上传 [英] Multiple file upload in php

问题描述

我想上传多个文件并将它们存储在一个文件夹中，并获取路径并将其存储在数据库中...任何您想要做多个文件上传的好例子...

注意：文件可以是任何类型的文件...

解决方案

知道这是一个旧的帖子，但一些进一步的解释可能是有用的人试图上传多个文件...这是你需要做的：

• 输入名称必须定义为数组，例如
  name =inputName []


• 输入元素必须有多个=multiple或多重


• 在您的PHP文件中使用$ _ FILES ['inputName'] ['param '] [index]


• 确保查找 空文件名和路径 ，数组可能包含空字符串。在计数之前使用array_filter（）。
  
  
  

  这里是一个简单的例子（显示相关代码）
  
  

  HTML：
  
  

   < input name =upload []type =filemultiple =multiple/> 
    

  PHP：
  
  

    // $ files = array_filter（$ _ FILES ['upload'] ['name']）;类似于在处理文件之前使用的东西。 
   //计算上传文件的数量
   $ total = count（$ _ FILES ['upload'] ['name']）; 
   
   //遍历每个文件
  （$ i = 0; $ i <$ total; $ i ++）{
   //获取临时文件路径
   $ tmpFilePath = $ _FILES ['upload'] ['tmp_name'] [$ i]; （$ tmpFilePath！=）{
   //设置我们的新文件路径
   $ newFilePath =。 /上传文件/ 。 $ _FILES [上传] [名] [$ i]; 
   
   //将文件上传到临时目录
   if（move_uploaded_file（$ tmpFilePath，$ newFilePath））{
   
   //在此处处理其他代码
   
  } 
  } 
  } 
    

  
  

  I want to upload multiple files and store them in a folder and get the path and store it in the database... Any good example you looked for doing multiple file upload...

  Note: Files can be of any type...

  解决方案

  I know this is a old post but some further explanation might be useful for someone trying to upload multiple files... Here is what you need to do:

  • Input name must be be defined as an array i.e. name="inputName[]"
  • Input element must have multiple="multiple" or just multiple
  • In your PHP file use the syntax "$_FILES['inputName']['param'][index]"
  • Make sure to look for empty file names and paths, the array might contain empty strings. Use array_filter() before count.

  here is a down and dirty example (showing just relevant code)

  HTML:

  <input name="upload[]" type="file" multiple="multiple" />
  

  PHP:

  //$files = array_filter($_FILES['upload']['name']); something like that to be used before processing files.
  // Count # of uploaded files in array
  $total = count($_FILES['upload']['name']);
  
  // Loop through each file
  for($i=0; $i<$total; $i++) {
    //Get the temp file path
    $tmpFilePath = $_FILES['upload']['tmp_name'][$i];
  
    //Make sure we have a filepath
    if ($tmpFilePath != ""){
      //Setup our new file path
      $newFilePath = "./uploadFiles/" . $_FILES['upload']['name'][$i];
  
      //Upload the file into the temp dir
      if(move_uploaded_file($tmpFilePath, $newFilePath)) {
  
        //Handle other code here
  
      }
    }
  }
  

  Hope this helps out!
