How to upload multiple files using codeigniter - php

Question

I want to upload multiple files using codeigniter.
I have two types of images beforeimage and afterimage. After uploading each image I make entry in database.
I am creating thumbnail as well. To amke it ease I created a separate function, but its not working. this logic works for single image upload.
Html
controller
foreach($_FILES["beforepicture"]['name'] as $key=>$files){
//if(isset($_FILES["beforepicture"]['name']) && $_FILES["beforepicture"]['name'] != ''){
$imagestatus = $this->upload_images($files,'beforepicture');
if(isset($imagestatus['name'])){
$inputdata = array('image' => $imagestatus['name'],
'lead_id' =>$inserted_id,
'user_id'=>$this->session->userdata['userdata']['userid'],
'when'=>'before');
$this->common_model->save('lead_images',$inputdata);
//}
}
}
function upload_images($data = NULL,$inputname=NULL){
if($data){
$this->load->library('image_lib');
// echo '<pre>';
// print_r($_FILES);
$new_name = time().$data;
$config = array(
'upload_path' => getcwd()."/assets/themes/default/avatars/",
'allowed_types' => "gif|jpg|png|jpeg",
'overwrite' => TRUE,
'max_size' => "2048000", // Can be set to particular file size , here it is 2 MB(2048 Kb)
// 'max_height' => "768",
//'max_width' => "1024",
'file_name' => $new_name
);
$this->load->library('upload', $config);
$this->upload->initialize($config);
//$this->upload->initialize($config);
if($this->upload->do_upload($inputname))
{
$image_data = $this->upload->data();
//thumb1
$config = array(
'source_image' => $image_data['full_path'], //path to the uploaded image
'new_image' => getcwd()."/assets/themes/default/avatars/thumb", //path to
'maintain_ratio' => true,
'width' => 180,
'height' => 200
);
$this->image_lib->initialize($config);
$this->image_lib->resize();
$message = array('name' => $image_data['file_name']);
}else
{
//echo $this->upload->display_errors(); die;
$message = array('failed' => $this->upload->display_errors());
}
return $message;
}
}

Try this
<?php
class My_Controller extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->library('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];
$this->upload->initialize($this->set_upload_options());
$this->upload->do_upload();
$fileName = $_FILES['userfile']['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;
}
}
