Question

PHP cookie problem

Asked by: rae_rae

I have the following code:
                  // check if the user id and password combination exist in database
                  $query  = "SELECT us_email, us_pass, us_type FROM us_user_ WHERE us_email = '$us_email'";
                  $result = mysql_query($query);
                  while($row = mysql_fetch_array($result, MYSQL_ASSOC))
                  {      
                        $us_email = $row['us_email'];
                        $pass     = $row['us_pass'];
                        $us_type  = $row['us_type'];
                        $ck_exp   = "login_exp";
                        $ck_typ   = "login_typ";
                        $expire   = time()+3600;
                        setcookie($ck_exp, $expire);      
                        setcookie($ck_typ, $us_type);
                  }


Notice the "setcookie($ck_typ, $us_type);" which is what I'm having difficulty with.
The cookie is read by:
                              if ( $_COOKIE[ck_typ] == admin ) {
                                    $_SESSION['db_is_logged_in'] = true;
                                    header("Location: processor.php?sender=admin_cpanel");
                              }
                              if ( $_COOKIE[ck_typ] != admin ) {
                                    $_SESSION['db_is_logged_in'] = true;
                                    header("Location: processor.php?sender=user_cpanel");
                              }

I am an admin in this system but my cookie keeps redirecting me to user_cpanel.

Please help me resolve this issue.

you have set
      $ck_typ   = "login_typ";

and your if condition is
  if ( $_COOKIE[ck_typ] == admin ) {

now if the value of    $ck_typ was admin then
      $ck_typ   = "admin";
your check for the if condition should be
   if ( $_COOKIE["ck_typ"] == "admin" ) {
                              $_SESSION['db_is_logged_in'] = true;
                              header("Location: processor.php?sender=admin_cpanel");
                        /* Make sure that code below does not get executed when we redirect. */
                    exit;
                         }

I have also tried many different things like:
                              $ck_typ = $HTTP_COOKIE_VARS["ck_typ"];

                              if ( $ck_typ == "admin" ) {
                                    $_SESSION['db_is_logged_in'] = true;
                                    header("Location: processor.php?sender=admin_cpanel");
                              }
                              if ( $ck_typ != "admin" ) {
                                    $_SESSION['db_is_logged_in'] = true;
                                    header("Location: processor.php?sender=user_cpanel");
                              }
and I've even echoed out the value of $ck_typ which seems to be null

are cookies allowed in ur system ?
the cookie wont be read on the same page. I assume that your check for   $_COOKIE[ck_typ] == admin is on the next page ?

 

by: rae_raePosted on 2006-08-08 at 21:07:01ID: 17276533

Cookies are enabled in the browser.
I have the following function in an includes script:
      // What type of user
      function redirect () {
            if ( $_COOKIE["ck_typ"] == "admin" ) {
                  $_SESSION['db_is_logged_in'] = true;
                  header("Location: processor.php?sender=admin_cpanel");
            }
            if ( $_COOKIE["ck_typ"] != "admin" ) {
                  $_SESSION['db_is_logged_in'] = true;
                  header("Location: processor.php?sender=user_cpanel");
            }
      }
But it still takes me to user_cpanel

 

by: sajuksPosted on 2006-08-08 at 21:12:16ID: 17276547

where is the include script  ? On the same page as where you are setting the cookie ? Then that wont work.
for ex
<?php
$value = 'something from somewhere';
setcookie("TestCookie", $value);
echo "Value of cookie is ".$_COOKIE["TestCookie"];
?>
this wont return any value.
The cookie will be set only when the page is redirected /reloaded.

 

by: rae_raePosted on 2006-08-08 at 21:16:49ID: 17276555

require ("_includes/CheckLoggedIn.php");

It is in another folder. I'm going to try echoing out the value in the required script.
Brb.

What a drag....
      // What type of user
      function redirect () {
            if ( $_COOKIE["ck_typ"] == "admin" ) {
                  $_SESSION['db_is_logged_in'] = true;
                  echo $_COOKIE[ck_typ];
                  exit();
                  header("Location: processor.php?sender=admin_cpanel");
            }
            if ( $_COOKIE["ck_typ"] != "admin" ) {
                  $_SESSION['db_is_logged_in'] = true;
                  echo $_COOKIE[ck_typ];
                  exit();
                  header("Location: processor.php?sender=user_cpanel");
            }
      }
Doesn't print anything whatsoever :[

 

by: sajuksPosted on 2006-08-08 at 21:19:11ID: 17276562

if the cooies are set on the same page, you could try something like this

$ck_typ= 'admin'; //instead of setting the value in a cookie , get it in a variable and pass that value
redirect($ck_typ);

  function redirect ($ck_typ ="") {
          if ( $ck_typ == "admin" ) {
               $_SESSION['db_is_logged_in'] = true;
               header("Location: http://search.google.com?sender=admin_cpanel");
               exit;
          } else {
               $_SESSION['db_is_logged_in'] = true;
               header("Location: http://search.google.com?sender=user_cpanel");
               exit;
          }
     }

did u try out the example i set ?
from where are you getting the value of admin ? In your select does us_type reflect that ?
   $us_type  = $row['us_type'];
    then       $ck_typ   =    $us_type ;
try echoing the value here for $ck_type.

 

by: rae_raePosted on 2006-08-08 at 22:03:14ID: 17276666

I'm still trying to impliment your example. Unfortunately, now if I login as admin or not, I am taken to admin_cpanel. I'm going to see if I made a mistake but so far, I don't see one.

 

by: sajuksPosted on 2006-08-08 at 22:15:18ID: 17276688

can u post the source code of your whole page (if its not too long).
are u deleting ur cookies on logout ? It might be that as you already are logged in as admin its redirecting you to the admin panel

 

by: rae_raePosted on 2006-08-08 at 23:05:58ID: 17276820

That helps so thanks.

Why the B grade ? Curious to know.

 

by: rae_raePosted on 2006-08-09 at 11:57:55ID: 17281895

It's not actually a stable solution for some reason. I do very much appreciate your help though and I did learn from you. I never knew that the cookie would not activate until the page re-loaded. I also got some great ideas as far as the new function is concerned. I'm still trying to get it to work flawlessly though. Unfortunately, the cookie is only set for the first three clicks at best ;[
