At a quick glance at the register.php file.. here is what I see.. Well without posting the whole user if statement.. I will just add the part around where *I think* it needs changed.
PHP Code:
if ($moderatenewmembers) {
eval("standarderror(\"".gettemplate("error_moderateuser")."\");");
} else {
$url = str_replace("\"", "", $url);
if (!$url) {
$url = "index.php?s=$session[sessionhash]";
}
eval("standardredirect(\"".gettemplate("redirect_registerthanks")."\",\"".iif(strpos($url,"register")>0,"index.php?s=$session[sessionhash]",$url)."\");");
}
see where it says : $url = "index.php?s=$session[sessionhash]";
I think in that if statement you can change that $url value to whatever you want.
$url = "http://www.somethingsomewhere.com";
or change the other values that have index.php on that page.
I could be wrong.. I will take a look at this here in a bit. Tell me what you think on this.
