[Plugin: SI CAPTCHA Anti-Spam] Temporary php files in captcha-temp directory

The files are normal because of a new feature where PHP Sessions are no longer required for the CAPTCHA. The new method uses temporary php files in a /captcha-temp/ folder to store the CAPTCHA codes until validation.

PHP sessions can still be reactivated by unchecking the setting: “Use CAPTCHA without PHP session”. Then the temporary files will no longer be created. But the reason I have to make the optional temporary files method is because some servers have broken PHP session handling, or some other plugins that break the sessions. So this new feature makes my plugin work for many more people out of the box.

Since the last upgrade, that /captcha-temp/ folder was not automatically created on any of the sites I use the plugin. I think something went wrong during the upgrade since I had to create it manually for all web sites.

Besides that the plugin works well and is a life saver, thanx Mike

Hi, Mike.
I am Indra. I have triey wp-content/plugins/si-captcha-for-wordpress/captcha-secureimage/test/captcha_test.php

Using session off, I think there is one drawback there. If the token not match, the php file under wp-content/plugins/si-captcha-for-wordpress/captcha-secureimage/captcha-temp/ will be undelete.
So I just add code below somewhere in my program:

foreach ( glob( $ctf_captcha_dir . ‘*.php’ ) as $filename ) {
@unlink ($filename);
}

it will delete all “zombie” token php file before new one will be generate.

Yeah, I realize the bug in my code and save more recent token and delete all old ones could be great solution. Anyway thx for the great plugin!

If you download the trunk version the fix is included

Sorry I had forgotten to upload the changed file. If you download the install, a new captcha_test.php is included.
