Codeigniter - PHP array return a single data - php

Question

I've a file uploader. I do the overwrite through the data. It makes me upload these data:
- Pict1.jpg
- Pict12.jpg
- Pict13.jpg
But when I tried to return it, its only showing pict1.jpg. Here the code
Controller:
function send(){
$mariupload = $this->upload_gambar($_FILES['gambar']);
if ($mariupload === FALSE) {
$upload = false;
}
if($upload = false){
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
} else {
$dataupload = $mariupload;
echo $dataupload;
}
private function upload_gambar($files){
//config buat upload gambar
$config['upload_path'] = 'path to upload';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = '1024';
$config['overwrite'] = '0';
$this->load->library('upload', $config);
$gambar = array();
if (is_array($files['name']) || is_object($files['name'])){
foreach ($files['name'] as $key => $gambar) {
$_FILES['gambar[]']['name']= $files['name'][$key];
$_FILES['gambar[]']['type']= $files['type'][$key];
$_FILES['gambar[]']['tmp_name']= $files['tmp_name'][$key];
$_FILES['gambar[]']['error']= $files['error'][$key];
$_FILES['gambar[]']['size']= $files['size'][$key];
$fileName = $gambar;
$images[] = $fileName;
$config['file_name'] = $fileName;
$this->upload->initialize($config);
if ($this->upload->do_upload('gambar[]')) {
$dataupload = $this->upload->data('file_name');
return $dataupload.'<br>';
} else {
$mariupload = false;
}
}
}
}
When i try to echo $dataupload in upload_gambar function, it works as an array. But its returning as a single data to send() function. Any idea?

Answer 1

Because you are sending just single file
$mariupload = $this->upload_gambar($_FILES['gambar']);
change this to
$mariupload = $this->upload_gambar($_FILES);
then in your upload_gambar handle it as foreach

Answer 2

You have a return inside the loop. A return will interrupt the loop as the function will not continue to be executed. Try to feed up an array instead.
Replace
return $dataupload.'<br>';
With
$return[] = $dataupload;
And at the end of the function append:
return $return;

I finally found the solution. Thanks to Jovi Wang on Facebook (https://www.facebook.com/jovi.wang.96?fref=ufi) . This is the clean code:
function send(){
$try = $this->upload_multiple($_FILES['gambar']);
if(!$try = false){
$anu= $this->upload_multiple($_FILES['gambar']);
foreach($anu as $key => $anu2){
echo $anu2.'<br>';
}
}
public function upload_multiple($files)
{
// echo '<pre>';
// print_r($files);
// echo '</pre>';
$config['upload_path'] = 'path to upload';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = 1024;
$config['overwrite'] = 0;
$config['encrypt_name'] = TRUE;
$this->load->library('upload');
$this->upload->initialize($config);
$data = array();
foreach($files['name'] as $key => $value)
{
if ( ! empty($files['name'][$key]))
{
$_FILES['gambar_single']['name'] = $files['name'][$key];
$_FILES['gambar_single']['name'] = $files['name'][$key];
$_FILES['gambar_single']['type'] = $files['type'][$key];
$_FILES['gambar_single']['tmp_name'] = $files['tmp_name'][$key];
$_FILES['gambar_single']['error'] = $files['error'][$key];
$_FILES['gambar_single']['size'] = $files['size'][$key];
if ($this->upload->do_upload('gambar_single'))
{
$data[] = $this->upload->data('file_name');
}
else
{
$data[] = $this->upload->display_errors();
}
}
else
{
$data[] = 'empty upload';
}
}
return $data;
}
