Redirecting user links to their profile2 pages

Question

I'm using the profiles2 module for my user profiles. I want to keep the user accounts hidden, and instead, use the profiles for public viewing. I disabled user pictures in users, and added an image field to the profile entity. When users post comments, the links point back to the user account. How can I change that behavior so links point back to that user's profile page? Also, how can I display the profile pics for these comments? Essentially, I'm wanting the normal user functionality to occur with profiles instead of users.

Answer 1

This can be done with a combination of

hook_preprocess_username (make links go to profile path)

Something like:

function MYTHEME_preprocess_username(&$variables) {
  $account = $variables['account']
  if($profile = profile2_load_by_user($account, 'profile_type')){
    // This gets passed onto theme_username
    $variables['link_path'] = 'user/' . $variables['uid'].'/profile/path';
    // Possibly:
    // $type = $profile->type();
    // $path = profile2_page_get_base_path($type) . '/' . $account->uid
  }
}

and then the picture override in

hook_preprocess_user_picture (override user picture)

Something like:

function MYTHEME_preprocess_user_picture(&$variables) {

  $account = variables['account'];
  if($profile = profile2_load_by_user($account, 'profile_type')){
    // You could use a custom 'display' parameter, e.g image_style
    $image = field_view_field('profile2', $profile, 'field_image');
    $variables['user_picture'] = render($image);
  }

}

Answer 2

Drilling down a bit, the picture there is generated inside comment.tpl.php by the user-picture.tpl.php template, inside of which it relies upon the $user_picture variable.

So, the easiest way might be to put something along these lines in your theme's template.php...

YOURTHEME_preprocess_user_picture(&$variables) {

  $account=$variables['account'];

  $variables['user_picture'] = // whatever you want it to be instead of the default

}

...with whatever logic you need based upon the user information passed in via the $account variable.

This would also have a possible added benefit of overriding this everywhere a user picture is similarly themed.
