Hi there

I'm a newbie in Mahara/PHP.

I'm trying to right a custom plugin (blocktype) in Mahara. I've gone through the tutorial of how to build a blocktype.

What I want to achieve is: storing the username/id of the current logged in user into a variable with end user entering any sort of information apart from clicking Save button.

I have a JS that uses this id to refer some resources in drupal. Also, the end users can share this page with other users.

In short: End users will import their own drupal resources (kind of forum entries) into Mahara pages and share with other users.

Using global $USER, I can get the current logged in userid. I want to save this into a variable in instance_config_form and pass it to render_instance. And I dont want any input fields in the form.

Can some one give me any ideas on how to do this?

Haven't tested it, but that should do it...

    public static function instance_config_form($instance) {
        global $USER;
        $configdata = $instance->get('configdata');
        $userid = (isset($configdata['userid']) && !empty($configdata['userid'] ? $configdata['userid'] : $USER->get('id'));
        
        return array(
            'userid' => array(
                'type'  => 'hidden',
                'value' => $userid,
            )
        );
    }

    public static function render_instance(BlockInstance $instance, $editing=false) {
        $configdata = $instance->get('configdata');
        return $configdata['userid'];
    }

A little explanation:

In function instance_config_form (3rd line: $userid = ...) set user id form value that was written/stored in DB, if it wasn't written yet, than use $USER->get('id')

In function render_instance get value of user id written/stored in the DB and than return that value, that should print it...
