I found this handy script on StackExchange that allows for multiple uploads. Except it doesn't work, for me, at least. In the HTML, I have a simple upload form that you can add more upload forms to. So you hit "Add upload" and another input is built. Simple stuff.

Here are the problems:
1. If I choose 1 file to upload, I get the following errors: Message: is_uploaded_file() expects parameter 1 to be string, array given and Message: Undefined offset: 1 repeated 5 times (in reference to the code below), and then shows Message: is_uploaded_file() expects parameter 1 to be string, array given again.
2. If I choose 2 files, I get Message: is_uploaded_file() expects parameter 1 to be string, array given twice.

The error array is always returned as You did not select a file to upload..

What am I doing wrong? Any ideas?

Here's my controller:

Code:
$dir = random_string('alnum', 10);

mkdir('/Applications/MAMP/htdocs/extras/uploads/temp/'.$dir);

$this->load->library('upload');

$error = 0;

for ($i = 0; $i < count($_FILES['userfile']['name']); $i++):

    $_FILES['userfile']['name']                = $_FILES['userfile']['name'][$i];

    $_FILES['userfile']['type']                = $_FILES['userfile']['type'][$i];

    $_FILES['userfile']['tmp_name']        = $_FILES['userfile']['tmp_name'][$i];

    $_FILES['userfile']['error']            = $_FILES['userfile']['error'][$i];

    $_FILES['userfile']['size']                = $_FILES['userfile']['size'][$i];

    $config['upload_path']                         = '/Applications/MAMP/htdocs/extras/uploads/temp/'.$dir;

    $config['allowed_types']                    = 'jpg|jpeg|gif|png';

    $this->upload->initialize($config);

    if ($this->upload->do_upload('userfile')):

        $error += 0;

    else:

        $error += 1;

    endif;

endfor;

if ($error > 0):

    $error = array('error' => $this->upload->display_errors());

    print_r($error);

else:

    $data = array('upload_data' => $this->upload->data());

    print_r($data);

endif;

And my <input>'s look like this:

Code:
&lt;input id="userfile1" name="userfile[]" type="file" /&gt;
