How do I save uploaded files with password protected ZIP file.
so I want to upload my files then I need to save them in password protection ZIP file
I think I need to make changes in processor.php. Could you help me @patrick
The file dmxConnectLib/lib/zip/Processor.php must be edited. I checked the PHP documentation and see that it is possible to password protect zip files since PHP version 7.2.
https://www.php.net/manual/en/ziparchive.setencryptionname.php
I have added it to the PHP file but I haven’t tested it, perhaps you can test it and improve when needed. The actions zip, zipdir, unzip and dir should now accept an extra options password. Creating a zip archive with password requires PHP 7.2.

Thank you @patrick your quick solution ,
but when I try, I encounter 2 problems.
-
I dont know how to assign the password (password will come from $_POST) in server connect UI
-
If I don’t define a password, it gives me the error message as follows.
- code: 0
- file: “/var/www/vhosts/bendensonraya.com/httpdocs/dmxConnectLib/lib/zip/Processor.php”
- line: 74
- message: “syntax error, unexpected ‘return’ (T_RETURN)”

Oh, that was some old code, I first tried to add the password to the create, but later moved it to the action methods. You can remove line 71 and 72.
You can pass the password using the options in the json. You have to edit the action file by hand, Wappler doesn’t know about the new password option.
The $password argument should also be removed from the create function.
public static function create($zipfile) {
I cant see the problem … sorry @patrick

Do you have PHP 7.2 or higher?
yes higher
PHP/7.2.24
Test the example from the the php documentation on your server.
https://www.php.net/manual/en/ziparchive.setencryptionname.php
It is possible that the ZIP extension for PHP is not compiled correctly. It needs to be compiled with libzip-dev >= 1.2.0.

Hello @patrick,
Php version : 7.3.12
now I can upload any file and save it as ZIP file. but an encrypted zip file does not occur. (I cant set password to zip file)
Current Libzip Version 1.3.2
Processor.php
Serverconnect Steps and JSON detail
there isnt any error . can you help ?
Yes example is working
In the zip step, shouldn’t it be {{upload1.path}} instead of just {{upload1}}
zip file created without password
Try changing in Processor.php:
$this->setEncryptionName($file, ZipArchive::EM_AES_256);
to:
$this->setEncryptionName(basename($file), ZipArchive::EM_AES_256);
