i guess $zip->open is not working
here is my code
function rmdir_recursive($dir) {
foreach(scandir($dir) as $file) {
if ('.' === $file || '..' === $file) continue;
if (is_dir("$dir/$file")) rmdir_recursive("$dir/$file");
else unlink("$dir/$file");
}
rmdir($dir);
}
if(isset($_POST))
{
if($_FILES["file"]["name"]) {
$filename = $_FILES["file"]["name"];
$source = $_FILES["file"]["tmp_name"];
$type = $_FILES["file"]["type"];
$name = explode(".", $filename);
$accepted_types = array('application/zip', 'application/x-zip-compressed', 'multipart/x-zip', 'application/x-compressed');
foreach($accepted_types as $mime_type) {
if($mime_type == $type) {
$okay = true;
break;
}
}
$continue = strtolower($name[1]) == 'zip' ? true : false;
if(!$continue) {
echo "The file you are trying to upload is not a .zip file. Please try again.";
}
/* PHP current path */
$path = dirname(__FILE__).'/packages/'; // absolute path to the directory where zipper.php is in
$filenoext = basename ($filename, '.zip'); // absolute path to the directory where zipper.php is in (lowercase)
$filenoext = basename ($filenoext, '.ZIP'); // absolute path to the directory where zipper.php is in (when uppercase)
$targetdir = $path . $filenoext; // target directory
$targetzip = $path . $filename; // target zip file
/* create directory if not exists', otherwise overwrite */
/* target directory is same as filename without extension */
if (is_dir($targetdir)) rmdir_recursive ( $targetdir);
mkdir($targetdir, 0777);
/* here it is really happening */
if(move_uploaded_file($source, $targetzip)) {
$zip = new ZipArchive; // create object
$res = $zip->open($targetzip); // open archive
if ($res === TRUE) {
$zip->extractTo($targetdir); // extract contents to destination directory
$zip->close();
echo 'extraced successed';
}else{
echo 'extraced failed';
}
echo "Your .zip file was uploaded and unpacked.";
} else {
echo "There was a problem with the upload. Please try again.";
}
}
