[wp-hackers] array_push on update_user_meta

[Gregory Lancaster]

I thought so.  One more question if you dont mind helping;

This is the function I wrote to determine what button to show on page load.
 But regardless if someone has been friended or not, it shows the add
friend option.  Is something wrong with this?


function friend_status($author_id) {
global $wpdb, $current_user;
      get_currentuserinfo();

  //authorID is the userID of the profile owner

  $active_user = $current_user->ID;
  $active_user_friends = get_user_meta($active_user, 'friends');

  if (in_array($author_id, $active_user_friends)) {
  $friend_status = "<button id='remove_friend'>Remove Friend</button>";
  } else {
  $friend_status = "<button id='add_friend'>Add Friend</button>";
  }

 return $friend_status;
}

Then on page:  echo $friend_status;
