I'm developing a wordpress site that is just a part of a bigger website developed with Drupal.
As I want just one registering form (at the Drupal website) I would like to know when a user arrives to the WordPress site if he/she is logged into the Drupal site (I have that already done) and then register this user using its unique user name and the same password for all them (as I cannot get the password from the Drupal site).
Is there anyway of registering that user silently and them logging he/she automatically? Or any alternative option you may think about?
Thank you in advance ))
