Multiple Images not uploading Only Last Select Image Uploaded - php

Question

I am uploading multiple images in codeigniter framework. When i select multiple images, it upload only last selected image.
Below is my controller code, where i am doing wrong?
$files = $_FILES;
for($i=0; $i< count($_FILES['item_image']['name']); $i++)
{
$_FILES['item_image']['name']= $files['item_image']['name'][$i];
$_FILES['item_image']['type']= $files['item_image']['type'][$i];
$_FILES['item_image']['tmp_name']= $files['item_image']['tmp_name'][$i];
$_FILES['item_image']['error']= $files['item_image']['error'][$i];
$_FILES['item_image']['size']= $files['item_image']['size'][$i];
$this->upload->initialize($config);
if ($this->upload->do_upload('item_image'))
{
$file_name=$this->upload->data('file_name');
$newdata = array(
'item_id'=>$last_id,
'image_name'=>$file_name
);
$this->Item_model->add_item_image($newdata);
$newdatatwo = array(
'item_image'=>$file_name
);
$this->Item_model->update_item($newdatatwo,$last_id);
$data['error_or_success_message'] = $this->session->set_flashdata('error_or_success_message', 'Item added Successfully!');
}else{
$data['error_or_success_message'] = $this->session->set_flashdata('error_or_success_message', 'Some Error, Please Try Again!');
}
}

Answer 1

The second condition in your for loop gets redefined in the first line of your for loop. I would check to make sure that isn't causing errors.

Refer The Below Code
Controller Code
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Multiple_upload extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->helper('form');
$this->load->helper('url');
}
public function index()
{
$this->load->view('upload');
}
public function Upload()
{
$files = $_FILES;
$config['upload_path'] = 'common_assets/images';
$config['allowed_types'] = 'jpg|gif|png';
$config['max_size'] = '';
$config['remove_spaces'] = true;
$config['overwrite'] = true;
$config['max_width'] = '';
$config['max_height'] = '';
$config['max_filename'] = 0;
foreach ($_FILES['item_image']['name'] as $key => $value)
{
$_FILES['item_image']['name']= $files['item_image']['name'][$key];
$_FILES['item_image']['type']= $files['item_image']['type'][$key];
$_FILES['item_image']['tmp_name']= $files['item_image']['tmp_name'][$key];
$_FILES['item_image']['error']= $files['item_image']['error'][$key];
$_FILES['item_image']['size']= $files['item_image']['size'][$key];
$this->load->library('upload', $config);
$this->upload->initialize($config);
if (!empty($value))
{
if (!$this->upload->do_upload('item_image'))
{
$error = array('error' => $this->upload->display_errors());
print_r($error);
exit();
}else{
$file_name=$this->upload->data('file_name');
//**********Database Entry*********************
// $newdata = array(
// 'item_id'=>$last_id,
// 'image_name'=>$file_name
// );
// $this->Item_model->add_item_image($newdata);
// $newdatatwo = array(
// 'item_image'=>$file_name

// $this->Item_model->update_item($newdatatwo,$last_id);
}
}
}
echo "<pre>Uploaded Successfully"; die;
}
}

//This works for me:
$config['upload_path'] = 'common_assets/images';
$config['allowed_types'] = 'jpg|gif|png';
$config['max_size'] = '';
$config['remove_spaces'] = true;
$config['overwrite'] = true;
$config['max_width'] = '';
$config['max_height'] = '';
$config['max_filename'] = 0;
$this->load->library('upload', $config);
foreach ($_FILES as $fieldname => $fileObject) {
if (!empty($fileObject['name'])) {
$this->upload->initialize($config);
if (!$this->upload->do_upload($fieldname)) {
$errors = $this->upload->display_errors();
redirect('error_page', $errors);
} else {
$data = array($fieldname => $this->upload->data());
extract($data[$fieldname]);
$$fieldname = $file_name;
}
}
}
$array_to_save = array('tbl_name_field_1' => $file_name_from_post_1,
'tbl_name_field_2' => $file_name_from_post_2);
