It is very hard to determine what this function does 'watthehell'.  Though at a guess. I would say it checks to see if the user is logged in.  Perhaps applies the user details to session variables?  It depends what the check_session function does.

 

Also, remember! Code tags.

check session function is like this ...

 

function check_session($val)

{

  return $val;

 

  $errmsg="Session has been expired.";

  if(isset($val)) return $val;

 

  $this->abort("Session Error ", $errmsg);

//  $this->redirect($this->error_template);

  exit;

}

i just wanted to ask how to use that function is_user() in php code.... 

 

can we use like this

 

<? if is_user()==true { ?>

display message u are logged in

<? } else { ?>

display login box

<? } ?>

[matthewhaworth]

<?php
$login = is_user();
if($login != false) {
?>
You are logged in.
<?php
}
else
{
?>
You are not logged in
<?php>
}
?>

Well it will do if the login form isn't in the if statement..

[watthehell]

the login form is in login.php file and this code i  kept on header.php file

 

<?php

  if ($is_logged==true) {

i need logout here 

  <? }

  else

  {

  ?>

  <? include("login.php");?>

 

  <? } ?>

I think your check_session function is messed up a bit.  You pass it the variable $val, and then, before ANY other code executes, you return $val.  So if you do this: $user = is_user();, then $user == $_SESSION['ISUSER'].  I would assume that would return "Admin", "Guest", "Registered", etc.

 

Please post your whole code so we can see more.  Just those two functions aren't enough to say "OK, here's what's wrong".

thnks for the reply man.... i will post my code here.... later
