This code will allow multiple files upload in codeigniter Framework with Javascript based file validation.

Create a new controller or add the following code to your existing controller.

public function do_upload()

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


	$data['page_name']              = 'imgupload'; // change this to your view name
        $data['page_title']             = 'Bulk Uploader'; //change this to your page title
        $this->load->view('backend/admin/index', $data); //change this accordingly to your application

private function set_upload_options()
//  upload an image options
    $config = array();
    $config['upload_path'] = 'uploads/demo'; //change this to your uploading path
    $config['allowed_types'] = 'jpg'; //change this to your allowed file types with | seperator
    $config['max_size']      = '0'; //change this to your max file size upload
    $config['overwrite']     = FALSE; // change this to TRUE if you want to allow overwrite

    return $config;

Add the following code to your view

<?php echo form_open_multipart('admin/do_upload');?> //change this to your controller name
<input id="buf" type="file" required multiple name="userfile[]" size="20" onchange="CheckFileName()" />
<input type="submit" value="upload" />

We have also used javascript validation for above script, Here is the JS Code

function CheckFileName() {
        var fileName = document.getElementById("buf").value
        if (fileName.split(".")[1].toUpperCase() == "JPG")
            return true;
        else {
            alert("File with " + fileName.split(".")[1] + " is invalid. Upload a valid file with JPG extensions");
            document.getElementById("buf").value = "";
        return true;
