Uploading multiple images with codeigniter to a database - php

Question

My functions upload only one image at a time, when the form is submitted. I can not upload multiple images at once. This is a huge problem because I am building a car-sales website, and people need to upload multiple car images.
My upload.php controller:
<?php
class Upload extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
$this->load->model('upload_model');
}
function index()
{
$this->load->view('common/header');
$this->load->view('nav/top_nav');
$this->load->view('upload_form', array('error' => ' ' ));
}
function do_upload()
{
if($this->input->post('upload'))
{
$config['upload_path'] = './images/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '1024';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}
else
{
$data=$this->upload->data();
$this->thumb($data);
$file=array(
'img_name'=>$data['raw_name'],
'thumb_name'=>$data['raw_name'].'_thumb',
'ext'=>$data['file_ext'],
'upload_date'=>time()
);
$this->upload_model->add_image($file);
$data = array('upload_data' => $this->upload->data());
$this->load->view('upload_success', $data);
}
}
else
{
redirect(site_url('upload'));
}
}
function thumb($data)
{
$config['image_library'] = 'gd2';
$config['source_image'] =$data['full_path'];
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 160;
$config['height'] = 110;
$this->load->library('image_lib', $config);
$this->image_lib->resize();
}
}
My upload_form.php view:
<?php $attributes = array('name' => 'myform');
echo form_open_multipart('/upload/do_upload',$attributes);?>
<input type="file" name="userfile" size="20" />
<input type="submit" value="upload" name="upload" />
<?php echo form_close(); ?>
My upload_model.php Model:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Upload_model extends CI_Model {
public function __construct()
{
parent::__construct();
}
function add_image($data)
{
$this->db->insert('jobs',$data);
}
}
I can't modify the function in a way that allows multiple image upload. I would highly appreciate any kind of guidance or help. Thank you in advance!

$files = $_FILES;
$count = count($_FILES['uploadfile']['name']);
for($i=0; $i<$count; $i++)
{
$_FILES['uploadfile']['name']= $files['uploadfile']['name'][$i];
$_FILES['uploadfile']['type']= $files['uploadfile']['type'][$i];
$_FILES['uploadfile']['tmp_name']= $files['uploadfile']['tmp_name'][$i];
$_FILES['uploadfile']['error']= $files['uploadfile']['error'][$i];
$_FILES['uploadfile']['size']= $files['uploadfile']['size'][$i];
$this->upload->initialize($this->set_upload_options());//function defination below
$this->upload->do_upload('uploadfile');
$upload_data = $this->upload->data();
$name_array[] = $upload_data['file_name'];
$fileName = $upload_data['file_name'];
$images[] = $fileName;
}
$fileName = $images;
what's happening in code??
well $_FILE---->it is an associative array of items uploaded to the current script via the POST method.for further look this LINK
it's an automatic variable avaliable within all scopes of script
function set_upload_options()
{
// upload an image options
$config = array();
$config['upload_path'] = LARGEPATH; //give the path to upload the image in folder
$config['remove_spaces']=TRUE;
$config['encrypt_name'] = TRUE; // for encrypting the name
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '78000';
$config['overwrite'] = FALSE;
return $config;
}
and in your html markup don't don't forget:
Input name must be be defined as an array i.e. name="file[]"
Input element must have multiple="multiple" or just multiple
3.$this->load->library('upload'); //to load library
4.The callback, $this->upload->do_upload() will upload the file selected in the given field name to the destination folder.
5.And the callback $this->upload->data() returns an array of data related to the uploaded file like the file name, path, size etc.
