It is very simple to use pure PHP multi file Upload. Look into this script

View

<form method="post" action="<?php echo base_url('users/upload/'); ?>" enctype="multipart/form-data">
    <label for="upload">Select : </label>
    <input type="file" name="userfile[]" id="userfile" multiple="multiple" />
    <input type="submit" name="fsubmit" id="fsubmit" value="Upload" />
</form>

Controller

public function album($id)
{
    if (isset($_FILES['userfile']['name'])) {
        // total files //
        $count = count($_FILES['userfile']['name']);
        // all uploads //
        $uploads = $_FILES['userfile'];

        for ($i = 0; $i < $count; $i++) {
            if ($uploads['error'][$i] == 0) {
                // FCPATH = root directory project
                move_uploaded_file($uploads['tmp_name'][$i], FCPATH . 'assets/gallery/' . $uploads['name'][$i]);
                echo $uploads['name'][$i] . "
";
            }
        }
    }
}

Hope this helps. Thanks!!
