Hey there, i am knocking my brain out here … I am trying to generate a zip file based on image paths coming from a url parameter. Ended up using the zipArchive standard like this way: https://itsolutionstuff.com/post/php-how-to-create-zip-file-and-download-using-ziparchive-example.html. Also tried this method https://processwire.com/api/ref/wire-file-tools/zip/ before … UNF without any luck on both methods. All I am getting is a zip file with zero bytes. No errors appear. I think the file isn't even been created in the first place and it is just downloading the defined zip file coming from $fileName Here is my code: <?php $lb_images = "[".htmlentities($_GET['images'])."]"; // $lb_images = ['/site/assets/files/1062/image-1.jpg','/site/assets/files/1062/image-2.jpg','/site/assets/files/1062/image-3.jpg', ...] function createZip($files_ = array(), $destination = '', $overwrite = false) { if(file_exists($destination) && !$overwrite) { return false; } $validFiles = []; if(is_array($files_)) { foreach($files_ as $file) { if(file_exists($file)) { $validFiles[] = $file; } } } if(count($validFiles)) { $zip = new ZipArchive(); if($zip->open($destination,$overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true) { return false; } foreach($validFiles as $file) { $zip->addFile($file,$file); } $zip->close(); return file_exists($destination); }else{ return false; } } $fileName = 'my_zip_'.time().'.zip'; $files_to_zip = $lb_images; $result = createZip($files_to_zip, $fileName); header('Content-Description: File Transfer'); header('Content-Type: application/octet-stream'); header('Content-Disposition: attachment; filename=' . $fileName); header('Content-Transfer-Encoding: binary'); header('Expires: 0'); header('Cache-Control: must-revalidate'); header('Pragma: public'); header('Content-Length: ' . filesize($fileName)); ob_clean(); flush(); readfile($fileName); exit; ?>
