upload multiple image with different name using codeigniter - php

Question

I am trying to upload the three images from html form,with three different names.But it shows error
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['file_name'] = $this->input->post('mobile_name').'_front.jpg';
$config['overwrite'] = TRUE;
$this->load->library('upload', $config);
if ($this->upload->do_upload('files'))
{
$_POST['mobile_img1']= $this->upload->data()['file_name'];
}
else
{
echo "image upload fails";
exit();
}
This my codeigniter code to upload one image.
I have three image input field in html code
<div class="row">
<div class="col-md-4 col-md-offset-4">
<div class="form-group">
<label class="control-label">Mobile Image Front</label>
<input type="file" name="mobile_img1" class="filestyle" data-placeholder="No file">
</div>
<div class="form-group">
<label class="control-label">Mobile Image Back</label>
<input type="file" name="mobile_img2" class="filestyle" data-placeholder="No file">
</div>
<div class="form-group">
<label class="control-label">Mobile Image Side</label>
<input type="file" name="mobile_img3" class="filestyle" data-placeholder="No file">
</div>
</div>
</div>
in this html field i need to upload the first input as mobilename_front.jpg , second as mobilename_back.jpg and third as mobilename_side.jpg and also i need to upload this names in db.Give some ideas to implement this,

My controller:
<?php
class My_Controller extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->library('upload');
}
public function file_upload(){
$files = $_FILES;
$cpt = count($_FILES['mobile_img']['name']);
for($i=0; $i<$cpt; $i++)
{
$mobileView=(($i == 0)?"_front":(($i == 1)?"_back":"_side")); //Here i assign first image(i = 0) as _front, second image(i = 1) as _back,third image(i = 2) as _side
$_FILES['mobile_img']['name']= $files['mobile_img']['name'][$i].$mobileView.time();// time() for time in seconds becauze we may need if same name uploaded file name
$_FILES['mobile_img']['type']= $files['mobile_img']['type'][$i];
$_FILES['mobile_img']['tmp_name']= $files['mobile_img']['tmp_name'][$i];
$_FILES['mobile_img']['error']= $files['mobile_img']['error'][$i];
$_FILES['mobile_img']['size']= $files['mobile_img']['size'][$i];
$this->upload->initialize($this->set_upload_options());
$this->upload->do_upload();
$fileName = $_FILES['mobile_img']['name'];
$images[] = $fileName;
}
$fileName = implode(',',$images);
$this->my_model->upload_image($fileName);
}
private function set_upload_options()
{
// upload an image options
$config = array();
$config['upload_path'] = './upload/'; //give the path to upload the image in folder
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '0';
$config['overwrite'] = FALSE;
return $config;
}
}
