Drupal. How to use an image field from the profile node instead of user picture (avatar)

Julia 19/01/2010

I've recently had to make default pictures for user pictures,
but they had to be defferent for different user roles.

I used the module content_profile
and created two profile content types for Student and Teacher roles.
So I decided to change a user picture derectly in my theme.

I change the preprocess function mytheme_preprocess_user_picture from the user module in the template.php file:

<?php
function mytheme_preprocess_user_picture(&$variables) {
$variables['picture'] = '';
  
    $account = $variables['account'];
    
    $user = user_load(array('uid' => $account->uid));    
    $roles = $user->roles;
    $profile = '';    
    if (is_array($roles)) {      
      if (array_search('student', $roles)) {
          $profile = 'studentprofile';
      } else if (array_search('sensei', $roles)) {
          $profile = 'profile';
      }
    }
    
    if (!empty($profile)) {
      $node_profile = content_profile_load($profile, $account->uid);
      $field_photo = content_fields('field_photo', $profile);
      
      $picture = content_view_field($field_photo, $node_profile);
    } else {
    
        // from default preprocess_user_picture:
        if (!empty($account->picture) && file_exists($account->picture)) {
          $picture = file_create_url($account->picture);
        }
        else if (variable_get('user_picture_default', '')) {
          $picture = variable_get('user_picture_default', '');
        }
    
        if (isset($picture)) {
          $alt = t("@user's picture", array('@user' => $account->name ? $account->name : variable_get('anonymous', t('Anonymous'))));
          $variables['picture'] = theme('image', $picture, $alt, $alt, '', FALSE);
          if (!empty($account->uid) && user_access('access user profiles')) {
            $attributes = array('attributes' => array('title' => t('View user profile.')), 'html' => TRUE);
            $variables['picture'] = l($variables['picture'], "user/$account->uid", $attributes);
          }
        }
        // 
        
    }
    $variables['picture'] = $picture;
}
?>
