Multiple file upload in CodeIgniter using MY_Upload – meet my library extension

The CodeIgniter’s upload library is great. But it only works for single file uploads. So I thought that an extension to allow for multiple files upload would be a nice addition to CI’s upload library. Hence, allow me to present you MY_Upload. The extension is hosted on Github. So go there and download it.

After downloading the repo, just move libraries/MY_Upload.php to your application/libraries/ directory.

How to use it:

First of all, let’s make the view for uploading multiple files:

<!DOCTYPE html>
<title><?php echo $title; ?></title>
<h1>Upload multiple files</h1>
<?php echo form_open_multipart();?>
<p>Upload file(s):</p>
<?php echo form_upload('uploadedimages[]','','multiple'); ?>
<br />
<br />
<?php echo form_submit('submit','Upload');?>
<?php echo form_close();?>

Now, in a controller’s method, if a form was submited, we set the configuration and load the library:

$config = array(
'upload_path' => './upload/',
'allowed_types' => 'jpg|gif',
'max_size' => '2048',
'multi' => 'all'

// load Upload library

As you can see, the $config array has a new key: “multi“. This key can accept one of three values:

  • ‘all’ = only upload if all files are uploaded
  • ‘halt’ = halt uploading after first encountered error
  • ‘ignore’ = ignore errors and continue uploading remaining files

Once we’ve loaded the library, we can simply call do_upload() on our input element:


Take care here: $this->upload->do_upload() returns FALSE only if an error was encountered AND:

  • either the user tried to upload only one file;
  • or the user tried to load more than one file BUT the $config[‘multi’] was set to ‘all‘.

After the upload, we can retrieve the data of the uploaded files with $this->upload->data():

echo '<pre>';
$uploaded = $this->upload->data();
echo '</pre>';

Also, in case of upload errors, we can retrieve the errors with $this->upload->display_errors:

echo '<pre>';
echo '</pre>';

If you have any problems in implementing or you think that we can implement something new, please write a comment below. Enjoy!


    1. Hello, when you load the library, inside the configuration array you should also mention a ‘multi’ key which can accept “all”, “halt” or “ignore” as value.
