Looking for someone to point me in the right direction on how to write an addon to limit registrations from a specific domain, ie. only [email protected] for example.

    Now trying to build my first plugin for Vanilla. Coming up with this:

    Parse error: syntax error, unexpected '{' in /home/forum/html/plugins/LimitRegistrations/default.php on line 19

    This is the line: if (!StringEndsWith($User['Email'], '') {

    not sure why. The other { } are balanced...

    <?php if (!defined('APPLICATION')) exit();
    // Define the plugin:
    // the 'LimitRegistrations' is the name of the Plugin folder
    $PluginInfo['LimitRegistrations'] = array(
        // just the name to display of the plugin below
        'Name' => 'LimitRegistrations',
        // a brief description
        'Description' => 'This plugin limits registrations to specific domains.',
        // each time you update plugin update version so you can upload it.
        'Version' => '1.0',
        'Author' => "Anonymoose"  // the author
    class LimitRegistrations extends Gdn_Plugin {
    public function UserModel_BeforeRegister_Handler($Sender, $Args) {
       $User = $Args['User'];
       if (!StringEndsWith($User['Email'], '') {
          $Sender->Validation->AddValidationResult('Email', 'We only allow people from');
          $Args['Valid'] = FALSE;
        // this allows you to enable and disable plugin
      public function Setup() {
    //class LimitRegistrations

    Changing line 19 to this:

    if (!(preg_match("/$/i", $User['Email']))) {

    Yes. After all, I did, and it is now posted as the LimitRegistrations plugin. The next step might be to add more features like limiting registrations by IP and so on and to add configuration form the dashboard. Otherwise, it just works.

  • At which line to add fake email

    @Anonymoose the plugin need update for vanilla 2.3
    @Todd Could you also take a look? the piece of code might not work under 2.3

  • Never mind, just replace $User['Email'] above into $Args['RegisteringUser']['Email']
