Is it possible to login using the external_fud_login, but with out it redirecting? is the redirecting important ? i wish to remove redirection ,so that i can use external_fud_login without disturbing my login process.

Also please could you tell me in which file i can find the redirect that takes place during the login using external_fud_login and if possible (cheeky) the line name or function name.

one last last thing. WOW THE API IS EXCELENT, WELL DONE. its the first time i have attempted anything like this in intergration terms and it has been much eaiser than any of the alternatives. also the fudforum support forum looks as though people actauly get help, which was the other element which helped me decide to use the forum.

Thank you

The api does not actually do any redirects, it only generates a "logged in" session id which it returns and sets a cookie for the user.

I think I'm having a similar problem, so I'll post in this thread.

I wanted to get the current login status to use in an external app, and added this function to fudapi.inc.php:

 function fud_get_current_uid()
 {
 	fud_use('cookies.inc');
 	fud_use('users.inc');

 	return _uid;
 }

The page that uses this works OK, but when it's used on a page with a form, and the form is submitted, it ends up redirecting to the forum index page. I haven't dug deep enough yet to figure out why.

So...
- any thoughts on why this might happen?
- should I be obtaining the current UID in a different way?

Thanks!

Maarten.

What was happening was that users.inc called user_init, which called sq_check(), which caused a "Header:" redirect.

I replaced my code with this:

        fud_use('cookies.inc');

        if (!($u = ses_get())) {
                return 0;
        } else {
                return $u->id;
        }

which seems to work fine; pls let me know if there's a better way to get the current UID from an external script.

Maarten.

You shouldn't do this like this. I would suggest reading the session id from the FUDforum cookie, who's name is found in GLOBALS.php (already pre-loaded by FUDPAI) and then running the query on the FUDForum's session table.

Alright, changed to so:

function fud_get_current_uid()
 {
	$sess_id = $_COOKIE[$GLOBALS['COOKIE_NAME']];

	if (empty($sess_id)) {
		return 0;
	}

	$q_str  =
		'SELECT user_id'
		. ' FROM '       . $GLOBALS['DBHOST_TBL_PREFIX']. 'ses'
		. ' WHERE ses_id=' . _esc($sess_id);

	$id = q_singleval($q_str);
	if (null === $id || 2000000000 <= $id) {
		return 0;
	}
	return $id;
}

Edit: Modified to filter out userids of anonymous users. Those will show up as not logged in.

You can also try this one:

<?
function external_fud_get_current_user_id() {
    
    __fud_login_common(1);
    
    $ses_id = $_COOKIE[$GLOBALS['COOKIE_NAME']];
    if(!empty($ses_id) && strlen($ses_id)==32) {
        $sys_id = __ses_make_sysid(($GLOBALS['FUD_OPT_2'] & 256), ($GLOBALS['FUD_OPT_3'] & 16));
        $r = q_singleval("SELECT user_id FROM ".$GLOBALS['DBHOST_TBL_PREFIX']."ses WHERE ses_id="._esc($ses_id)." AND sys_id="._esc($sys_id)." AND user_id<2000000000");
        return $r?$r:0;
    } 
    return 0;
}
?>

It's more safe, as it also checks sys_id.
