In the past 2 days we have talked about the use of Facebook Connect module.
Drupal 7 – Allow Facebook login using Facebook Connect
Drupal 7 – Override the Facebook Connect login button theme
In this post, i will show you how to render the Facebook Login button programmatically in the Drupal user registration and login page.
The following code will render the Facebook Login button programmatically.
$user_profile = fbconnect_user_profile();
$attr = array();
if (variable_get('fbconnect_fast_reg', 0) && variable_get('fbconnect_reg_options', 0)) {
$attr = array('perms' => 'email');
}
$ss__facebook_connect = fbconnect_render_button($attr);
Eureka!
