how to unzip uploaded zip file? - php

Question

I am trying to upload a zipped file using codeigniter framework with following code
function do_upload()
{
$name=time();
$config['upload_path'] = './uploadedModules/';
$config['allowed_types'] = 'zip|rar';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_view', $error);
}
else
{
$data = array('upload_data' => $this->upload->data());
$this->load->library('unzip');
// Optional: Only take out these files, anything else is ignored
$this->unzip->allow(array('css', 'js', 'png', 'gif', 'jpeg', 'jpg', 'tpl', 'html', 'swf'));
$this->unzip->extract('./uploadedModules/'.$data['upload_data']['file_name'], './application/modules/');
$pieces = explode(".", $data['upload_data']['file_name']);
$title=$pieces[0];
$status=1;
$core=0;
$this->addons_model->insertNewModule($title,$status,$core);
}
}
But the main problem is that when extract function is called, it extract the zip but the result is empty folder. Is there any way to overcome this problem?

Answer 1

$zip = new ZipArchive;
$res = $zip->open($fileName);
if($res==TRUE)
{
$zip->extractTo($path.$fileName);
echo "<pre>";
print_r($zip);//to get the file type
$zip->close();

Answer 2

try this :
<?php
exec('unzip filename.zip');
?>

Answer 3

Hmm.., I think you set an incorrect path of your uploaded zip file OR your destination path ('./application/modules/') is incorrect.
Try this :
$this->unzip->extract($data['upload_data']['full_path'], './application/modules/');
I use this -> $data['upload_data']['full_path'], to make sure that it's a real path of the uploaded file.
Hope it helps :)

Answer 4

same problem i faced few min back.if you observe carefully you find
please copy zip file and paste to folder contain programe file(.php) after that you
i think file is not store in temp folder.
if(preg_match("/.(zip)$/i", $fileName))
{
$moveResult= move_uploaded_file($fileTmpLoc, $fileName);
if($moveResult == true)
{
$zip = new ZipArchive;
$res = $zip->open($fileName);
if($res==TRUE)
{
$zip->extractTo($path.$fileName);
echo "<pre>";
print_r($zip);
$zip->close();
} else {
echo 'failed';
}
}
unlink($fileName); // Remove the uploaded file from the PHP temp folder
//exit();
}`

class Upload extends CI_Controller {
function __construct(){
parent::__construct();
// load ci's Form and Url Helpers
$this->load->helper(array('form', 'url'));
}
function index(){
$this->load->view('upload_form_view', array('error' => ' ' ));
}
function file_upload(){
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'zip';
$config['max_size'] = '';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload()){
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form_view', $error);
}else{
$data = array('upload_data' => $this->upload->data());
$zip = new ZipArchive;
$file = $data['upload_data']['full_path'];
chmod($file,0777);
if ($zip->open($file) === TRUE) {
$zip->extractTo('./uploads/');
$zip->close();
echo 'ok';
} else {
echo 'failed';
}
$this->load->view('upload_success_view', $data);
}
}
}

In case anyone comes here for same question, just add chmod($file,0777); to the original code posted yetAnotherSE. That solves the issue of empty files.
