I am using ZipArchive with the following code to create zip files. It works well in all browsers on a Mac. But it says the file is invalid on any browser on a Windows computer. I don't understand why. I emailed the supposedly corrupt file from the Windows computer to myself and opened it on my Mac computer, and it worked fine. I also read through all the suggestions on this thread and tried all of them, with no luck.
Do you see anything wrong with my code?
if(extension_loaded('zip')){
if(isset($post['afiles']) and count($post['afiles']) > 0){
$zip = new ZipArchive();
$url = get_stylesheet_directory();
$filepath = $url;
$zip_name = "DSV".time().".zip";
if($zip->open($zip_name, ZIPARCHIVE::CREATE)!==TRUE){
$error .= "Error";
}
foreach($post['afiles'] as $file){
// get the file directory url from the file ID
$path = get_attached_file( $file );
// add each file to the zip file
$zip->addFile($path, basename($path));
}
$zip->close();
ob_clean();
header('Content-type: application/zip');
header('Content-Disposition: attachment; filename="'.$zip_name.'"');
readfile($zip_name);
unlink($zip_name);
}else
$error .= "* Please select file to zip <br/><br />";
}else
$error .= "* You do not have the ZIP extension<br/><br />";
I echoed basename($path) to confirm that there are no slashes. It is simply the filename like "this-is-my-file.docx". Thanks for any insight!
Edit: The exact error in Windows says:
Compressed (zipped) Folders Error
Windows cannot open the folder. The Compressed (zipped) Folder 'C:\Users\krist\Downloads\DWV1620652983.zip' is invalid.
