Multiple files upload in Codeigniter - php

Question

I want to upload multiple files using single element. So I try this example.
Multiple files upload (Array) with CodeIgniter 2.0
This is my form
<form enctype="multipart/form-data" class="jNice" accept-charset="utf-8" method="post" action="http://xxxx.dev/admin/add_estates">
<fieldset>
<label>Title * : </label>
<input type="text" class="text-long" value="" name="title">
<label>Description : </label>
<textarea class="mceEditor" rows="10" cols="40" name="description"></textarea>
<label>Image : </label>
<input type="file" multiple="" name="images[]">
<button class="button-submit" type="submit" name="save" id="">Save</button>
</fieldset>
</form>
This is my controller
public function add_estates()
{
$data['page_title'] = "© IDEAL - Administrator - Real State - Add Real Estate";
$data['main_content'] = 'admin/add_estates';
if ($this->input->post() !== FALSE) {
$this->load->library('form_validation');
$this->form_validation->set_rules('title', 'Career Title', 'trim|required');
if ($this->form_validation->run() !== FALSE) {
$title = $this->input->post('title');
$description = $this->input->post('description');
if (!empty($_FILES['images']['name'][0])) {
if ($this->upload_files($title, $_FILES['images']) === FALSE) {
$data['error'] = $this->upload->display_errors('<div class="alert alert-danger">', '</div>');
}
}
if (!isset($data['error'])) {
$this->admin_model->add_estate($title, $description, $image_name);
$this->session->set_flashdata('suc_msg', 'New real estate added successfully');
redirect('admin/add_estates');
}
}
}
$data['suc_msg'] = $this->session->flashdata('suc_msg');
$this->load->view('layout_admin', $data);
}
This is my file upload method
private function upload_files($title, $files)
{
$config = array(
'upload_path' => './upload/real_estate/',
'allowed_types' => 'jpg|gif|png',
'overwrite' => 1,
);
$this->load->library('upload', $config);
foreach ($files['name'] as $key => $image) {
$_FILES['images']['name']= $files['name'][$key];
$_FILES['images']['type']= $files['type'][$key];
$_FILES['images']['tmp_name']= $files['tmp_name'][$key];
$_FILES['images']['error']= $files['error'][$key];
$_FILES['images']['size']= $files['size'][$key];
$config['file_name'] = $title .'_'. $image;
$this->upload->initialize($config);
if ($this->upload->do_upload($image)) {
$this->upload->data();
} else {
return false;
}
}
return true;
}
But it give You did not select a file to upload. every time. What is the issue?

Answer 1

I change upload method with images[] according to #Denmark.
private function upload_files($path, $title, $files)
{
$config = array(
'upload_path' => $path,
'allowed_types' => 'jpg|gif|png',
'overwrite' => 1,
);
$this->load->library('upload', $config);
$images = array();
foreach ($files['name'] as $key => $image) {
$_FILES['images[]']['name']= $files['name'][$key];
$_FILES['images[]']['type']= $files['type'][$key];
$_FILES['images[]']['tmp_name']= $files['tmp_name'][$key];
$_FILES['images[]']['error']= $files['error'][$key];
$_FILES['images[]']['size']= $files['size'][$key];
$fileName = $title .'_'. $image;
$images[] = $fileName;
$config['file_name'] = $fileName;
$this->upload->initialize($config);
if ($this->upload->do_upload('images[]')) {
$this->upload->data();
} else {
return false;
}
}
return $images;
}

You should use this library for multi upload in CI

public function index() {
$user = $this->session->userdata("username");
$file_path = "./images/" . $user . '/';
if (isset($_FILES['multipleUpload'])) {
if (!is_dir('images/' . $user)) {
mkdir('./images/' . $user, 0777, TRUE);
}
$files = $_FILES;
$cpt = count($_FILES ['multipleUpload'] ['name']);
for ($i = 0; $i < $cpt; $i ++) {
$name = time().$files ['multipleUpload'] ['name'] [$i];
$_FILES ['multipleUpload'] ['name'] = $name;
$_FILES ['multipleUpload'] ['type'] = $files ['multipleUpload'] ['type'] [$i];
$_FILES ['multipleUpload'] ['tmp_name'] = $files ['multipleUpload'] ['tmp_name'] [$i];
$_FILES ['multipleUpload'] ['error'] = $files ['multipleUpload'] ['error'] [$i];
$_FILES ['multipleUpload'] ['size'] = $files ['multipleUpload'] ['size'] [$i];
$this->upload->initialize($this->set_upload_options($file_path));
if(!($this->upload->do_upload('multipleUpload')) || $files ['multipleUpload'] ['error'] [$i] !=0)
{
print_r($this->upload->display_errors());
}
else
{
$this->load->model('uploadModel','um');
$this->um->insertRecord($user,$name);
}
}
} else {
$this->load->view('uploadForm');
}
}
public function set_upload_options($file_path) {
// upload an image options
$config = array();
$config ['upload_path'] = $file_path;
$config ['allowed_types'] = 'gif|jpg|png';
return $config;
}

<?php
if(isset($_FILES[$input_name]) && is_array($_FILES[$input_name]['name'])){
$image_path = array();
$count = count($_FILES[$input_name]['name']);
for($key =0; $key <$count; $key++){
$_FILES['file']['name'] = $_FILES[$input_name]['name'][$key];
$_FILES['file']['type'] = $_FILES[$input_name]['type'][$key];
$_FILES['file']['tmp_name'] = $_FILES[$input_name]['tmp_name'][$key];
$_FILES['file']['error'] = $_FILES[$input_name]['error'][$key];
$_FILES['file']['size'] = $_FILES[$input_name]['size'][$key];
$config['file_name'] = $_FILES[$input_name]['name'][$key];
$this->upload->initialize($config);
if($this->upload->do_upload('file')) {
$data = $this->upload->data();
$image_path[$key] = $path ."$data[file_name]";
}else{
$error = $this->upload->display_errors();
$this->session->set_flashdata('msg_error',"image upload! ".$error);
}
}
return json_encode($image_path);
}
