rmdir($dir);
}
// upload and check the file is in valid format
if($_FILES["zip_file"]["name"]) {
$filename = $_FILES["zip_file"]["name"];
$source = $_FILES["zip_file"]["tmp_name"];
$type = $_FILES["zip_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) {
$message = "The file you are trying to upload is not a .zip file. Please try again.";
}
/* PHP current path */
$path = dirname(__FILE__).'/'; // 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);
//UNZIPPING THE ZIP FILE CODE
if(move_uploaded_file($source, $targetzip)) {
$zip = new ZipArchive();
$x = $zip->open($targetzip); // open the zip file to extract
if ($x === true) {
$zip->extractTo($targetdir); // place in the directory with same name
$zip->close();
unlink($targetzip);
}
$message = "Your .zip file was uploaded and unpacked.";
} else {
$message = "There was a problem with the upload. Please try again.";
}
}
