Is there a signup functionality?
If you have version 4.0+ this feature is implemented and you only need to switch it on inside configuration file.
For versions 3.0 and below:
If you want sign up functionality you can download php form that register users to FileGator from here. Put this script inside main filegator/ folder and update settings if necessary. You can access this script with a direct link (example: http://yoursite.com/filegator/signup.php).
This is a “Beta” functionality, currently not supported but this can be a good starting point for building your own custom signup form. Don’t forget to read “Security Notes” FAQ if you are allowing users to signup.
If you want to add “Sign Up” button on FileGator login form Open filegator/include/views/login.php and right after this line:
<input class="nice radius button" type="Submit" name="submit" value="Sign in">
add another line with this code and replace yoursite.com with your own site name:
<input class="nice radius secondary button" style="float:left;" type="Submit" value="Sign up" onclick="window.location='http://yoursite.com/filegator/signup.php'; return false;">
