Need help finding proper location for new thread code in register.php...

[fly]

I set my forum up to auto generate a thread for our new users after they confirm the email address. The code works, but not all the time. I'm guessing that I have it in the wrong area in the register.php script. Can someone here point me to where it should go?

I suck at PHP coding, so thanks for your help.

Here is the code I'm using:

PHP Code:

// ########## START THREAD CREATION ##########
            $forumid = $pmoptions['regforum'];
            $foruminfo = fetch_foruminfo($forumid);
            $post[title] = $pmoptions['regpmtitle'];
            $post[message] = $pmoptions['regpmtext'];
            $post[poststarttime] = TIMENOW;
            $post[posthash] = md5($post[poststarttime] . $bbuserinfo['userid'] . $bbuserinfo['salt']);
            $post['emailupdate'] = 9999;
            build_new_post('thread', $foruminfo, array(), 0, $post, $errors);
            // ########## END THREAD CREATION ########## 


and I put it after this line in register.php:

PHP Code:

// delete activationid
        //$DB_site->query("DELETE FROM " . TABLE_PREFIX . "useractivation WHERE userid=$userinfo[userid] AND type=0");
