Error in php snippet using tokens: Show profile field if it isn´t empty
You must refer to the actual field in your snippet. Try something like:

&lt;?php 
global $user;    
if (isset($user-&gt;profile-curso-basico[LANGUAGE_NONE][0]['value'])) {
  echo $user-&gt;profile-curso-basico[LANGUAGE_NONE][0]['value'];
} ?&gt;
