Is it possible to create a link to send private message to CURRENT USER in the node (to the author of the node content to be more precise). I'm using the Privatemsg module. I was trying to do this with the Display suite dynamic fields, but I am not able.

I found that the Privatemsg module comes with an option to "Display link on the selected content types. So, I have the "contact current member link" right in the content type, but it shows only for logged in users.

Is there any configuration or hook that I can implement to show the same link to anonymous user?

This is the code that shows the link.

function privatemsg_node_view($node, $view_mode) {
  $types = array_filter(variable_get('privatemsg_link_node_types', array()));
  $url = privatemsg_get_link(user_load($node->uid));
  if (in_array($node->type, $types) && !empty($url) && ($view_mode == 'full' || (variable_get('privatemsg_display_on_teaser', 1) && $view_mode == 'teaser'))) {
    $node->content['links']['#links']['privatemsg_link'] = array(
      'title' => t('Contact member'),
      'href' => $url . '/' . t('Message regarding @node', array('@node' => $node->title)),
      'query' => drupal_get_destination(),
      'attributes' => array('class' => 'button radius privatemsg-send-link privatemsg-send-link-node'),
    );
  }
} 

To make it clearer, I don't want anonymous user to send messages. What I want is just a link to log in for anonymous users. Expressing it with pseudo-code...

global $user;

if (isset($user->roles[1])) {
  // Do not show button to Anonymous user and show something else or a button to log in (THE CODE FOR LOG IN)
  echo "something else";
}
else {
  // Show button to logged in user (the code of "Send author a message" button)
}
  • look at this and this post...you can find the answer, or at least can be helpful... – mixerowsky Jul 22 '13 at 23:38
  • mixerowsky, thank you alot for your answer. The links you have shared is very helpful, anyway, i found that privatemsg module comes with an option to "Display link on the selected content types", and with that, you have a link "Send author a message" right in the content type or node that you want. This link can be customized with css and the text can be altered with stringoverrides‎ module. Thank you bro ;) – hailton Jul 23 '13 at 0:22
  • Hello again mixerowsky. Do you know how to show that link to anonymous user also? Thank you – hailton Jul 23 '13 at 3:25
  • @user1754562 Privatemsg links don't work for anonymous. There is an outstanding feature request for this: drupal.org/node/1988848 – Patrick Kenny Jul 23 '13 at 5:05
  • yes, it is impossible to send private message to anonymous user, that user is not registered... – mixerowsky Jul 23 '13 at 11:00

I did it with a Display suite custom code field. With it I am able to use some PHP code.

global $user;
// If the user is anonymous (role=1) show this; otherwise show nothing.
if (isset($user->roles[1])) {
  print l(t('Contact member'), 'user/login', array('attributes' => array('class' => array('radius', 'button'))));
}

So, when the user is logged-in, this code above will be replaced with the contact member link (Send author a message).
