Yeah, we were talking about MOP vars, I just got confused with another one and replied too soon. The example for MOP vars in the other thread covers that
viewtopic.php?f=4&t=14242&p=29268#p29246Still, you'll need to save these MOP vars somewhere that'll last so you can use it later after the registration with some customization. You could save them in the
$_SESSION or in a cookie. That way, for example, if you use the hack to log the person in automatically after creating his account, you could use the MOP var to redirect him there.
If the problem is login, then add
?redirect_to=/?p=123 at the end of the login URL, i.e.
/wp-login?redirect_to=/?p=123. You can get the post/page ID from the MOP vars to create this link dynamically.
Does that help?
