Multiple file upload in php

Question

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...

Answer 1

Here is a function I wrote which returns a more understandable $_FILES array.

function getMultiple_FILES() {
    $_FILE = array();
    foreach($_FILES as $name => $file) {
        foreach($file as $property => $keys) {
            foreach($keys as $key => $value) {
                $_FILE[$name][$key][$property] = $value;
            }
        }
    }
    return $_FILE;
}

Answer 2

this simple script worked for me.

<?php

foreach($_FILES as $file){
  //echo $file['name']; 
  echo $file['tmp_name'].'</br>'; 
  move_uploaded_file($file['tmp_name'], "./uploads/".$file["name"]);
}

?>

HTML

1. create div with id='dvFile';

2. create a button;

3. onclick of that button calling function add_more()

JavaScript

function  add_more() {
  var txt = "<br><input type=\"file\" name=\"item_file[]\">";
  document.getElementById("dvFile").innerHTML += txt;
}

PHP

if(count($_FILES["item_file"]['name'])>0)
 { 
//check if any file uploaded
 $GLOBALS['msg'] = ""; //initiate the global message
  for($j=0; $j < count($_FILES["item_file"]['name']); $j++)
 { //loop the uploaded file array
   $filen = $_FILES["item_file"]['name']["$j"]; //file name
   $path = 'uploads/'.$filen; //generate the destination path
   if(move_uploaded_file($_FILES["item_file"]['tmp_name']["$j"],$path)) 
{
   //upload the file
    $GLOBALS['msg'] .= "File# ".($j+1)." ($filen) uploaded successfully<br>";
    //Success message
   }
  }
 }
 else {
  $GLOBALS['msg'] = "No files found to upload"; //No file upload message 
}

In this way you can add file/images, as many as required, and handle them through php script.

I run foreach loop with error element, look like

 foreach($_FILES['userfile']['error'] as $k=>$v)
 {
    $uploadfile = 'uploads/'. basename($_FILES['userfile']['name'][$k]);
    if (move_uploaded_file($_FILES['userfile']['tmp_name'][$k], $uploadfile)) 
    {
        echo "File : ", $_FILES['userfile']['name'][$k] ," is valid, and was                      successfully uploaded.\n";
    }

    else 
    {
        echo "Possible file : ", $_FILES['userfile']['name'][$k], " upload attack!\n";
    }   

 }

Answer 5

It's not that different from uploading one file - $_FILES is an array containing any and all uploaded files.

There's a chapter in the PHP manual: Uploading multiple files

If you want to enable multiple file uploads with easy selection on the user's end (selecting multiple files at once instead of filling in upload fields) take a look at SWFUpload. It works differently from a normal file upload form and requires Flash to work, though. SWFUpload was obsoleted along with Flash. Check the other, newer answers for the now-correct approach.

Answer 6

I know this is an 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 file path
  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!
