Upload multiple files/images using PHP

                        You can upload single file and image easily in PHP. Now we are going to know how to upload multiple files and images using PHP. You can upload more than one images or files at the time using PHP. It can done using by array concepts.

Form for upload multiple images:

               
                     First you need to make form for upload more images. Your form should be like following:

<form action="#" method="post" enctype="multipart/form-data">
<input type="file" name="file[]" id="file" multiple="multiple">
<input type="file" name="file[]" id="file" multiple="multiple">
 <input type="submit" id="submit" name="submit" value="submit">
 </form>

                  You should add enctype="multipart/form-data" for upload files. You can see above where the name of file tag should be array like name="file[]" for store multiple values.

Upload multiple images using PHP:


                       Similarly upload single image, you will get image values by $_FILES['file']['name'] in PHP while submitting a form. You need temporary name of image to pass one of the parameter in move_uploaded_file() in order to upload files. If you've a single image, then you can upload easily by move_uploaded_file($_FILES['file']['tmp_name'],$name). But you need to upload multiple images. So you've to get values as an array. Then upload each image using loop. Consider the following example. Here it describes how to get temporary name of each image one by one using loop in PHP.


<?php
if(isset($_POST['submit']))
{
 $name=$_FILES['file']['name'];
 foreach($name as $val => $name1)
 {
   $file_name=$name1;
   $tmp=$_FILES['file']['tmp_name'][$val];
  move_uploaded_file($tmp,$_SERVER['DOCUMENT_ROOT'].'img/'.$file_name);
 }
}

?>
<html>
<body>
<form action="#" method="post" enctype="multipart/form-data">
<table>
<tr><td><input type="file" name="file[]" id="file" multiple="multiple"></td></tr>
<tr><td><input type="file" name="file[]" id="file" multiple="multiple"></td></tr>
<tr><td><input type="submit" id="submit" name="submit" value="submit"></td></tr>
</table>
</form>
</body>
</html>

             
     
     Where,
                move_uploaded_file() - to upload files to desired location.
                $_SERVER['DOCUMENT_ROOT'] gives the root directory of current script executing.
You can upload multiple files as well as images using this PHP script.
