Bit of an awkward one.

The client wants a system where they send us a link e.g. mycraftsite.com?userid=abc123 and from there we need to populate the user table.

I am new to craft but I am assuming the correct way is to use a plugin, grab the header data and somehow insert it using a hook, but I don't see any available for before the site renders.

Can anyone help point me in the right direction?

  • Are the passing in the username and email through the link? How is the password supposed to get set?

You would most likely want to add a controller to your custom plugin, with an 'action' method designed to handle the url request and generate a user; using 'post' or 'get' to pass parameters to the controller action.

In the controller action, you can access your parameters using:

$username = craft()->request->getParam('username');

You can then populate a new User Model using the passed params and save the model.

$user = new UserModel();

$user->username   = $username;
$user->email      = $email;
$user->firstName  = $firstName;
$user->lastName   = $lastName;
    'customField' => $customFieldValue


// We now have a user Id, so assign user to a group
craft()->userGroups->assignUserToGroups($user->id, $groupId);

// or to multiple groups
//craft()->userGroups->assignUserToGroups($user->id, [$groupId, $otherGroupId]);

However, by default, controller actions are only accessible to logged-in users. If you want to allow anonymous access you would need to specifically allow it using the $allowAnonymous property. This definitely introduces some security issues however, so proceed with caution. For example: definitely do not just assign user group(s) blindly from passed parameters or someone might be able to give themselves admin access!

  • That is exactly what I was looking for, thanks! can you recommend the best way of hooking it in? The client will provide this link to be used on initial site load, so I need to hook it in before the site renders initially.

  • It will be enabled as soon as you activate your plugin — so create plugin; place in plugins folder; goto to plugin settings, install and activate. Check out the plugin docs for more info on setting up, installing plugins, etc and/or start with a plugin template like the BusinessLogic Template plugin. Commented Feb 16, 2015 at 22:14
