[SOLVED] Calender script not working with session

matt.sisto · March 18, 2009

Does anybody know why my cal.php does not work with the session, it just redirects to the loginform1.php.

cal.php
<?php
session_start();

  if (!isset($_SESSION['username']))
    {
   header("Location: loginform1.php");
   echo ("Welcome $session[username]");
   exit();
    }
?>

Where are you setting the session?

Also, there's no need to echo stuff to the user, or exit() after you've redirected them to login.php. They won't even see it so there's not much point...

pkSML · March 18, 2009

Obviously, you're not properly logged in.

Just for the moment, copy and paste this data at the VERY TOP of your cal.php script.

<?php
session_start();
echo "<PRE>"; var_dump($_SESSION); echo "</PRE>";
exit();
?>

What output does it give?

matt.sisto · March 18, 2009

array(1) {
  ["username"]=>
  &NULL
}

Unless of course the re-direct fails..

I'm setting the session in the logincheck1.php script

<?php
  
session_start();
require "dbconn2.php";

//Using the function mysql_real_escape_string() AFTER a connection
//has been established will clean incoming variables and prevent
//users from tampering with your SQL by inserting some of their own
$email_address = mysql_real_escape_string($_POST['email_address']);
$passwd = mysql_real_escape_string($_POST['passwd']);
$id = mysql_real_escape_string($_POST['id']);


if($id == 'client') {
   $sql = "SELECT * FROM client WHERE email_address='".$email_address
        ."' AND passwd='".$passwd."'";
   $result = mysql_query ($sql, $connection) or die ("Could not perform query $sql <br />".mysql_error());
   $row = mysql_fetch_row($result);
}
else if($id == 'consultant') {
   $sql = "SELECT * FROM consultant WHERE email_address='".$email_address
        ."' AND passwd='".$passwd."'";
   $result = mysql_query ($sql, $connection) or die ("Could not perform query $sql <br />".mysql_error());
   $row = mysql_fetch_row($result);
}
else if($id == 'organisation') {
    $sql = "SELECT * FROM organisation WHERE email_address='".$email_address
        ."' AND passwd='".$passwd."'";
   $result = mysql_query ($sql, $connection) or die ("Could not perform query $sql <br />".mysql_error());
   $row = mysql_fetch_row($result);
}
else{
   echo 'Incorrect type';
}

if ($row != null)

{
      $_SESSION['username'] = $row['first_name'];
      header("Location: index.php");
      exit();
}

else
{
	header("Location: loginform1.php");
	exit();
}
     
?>

if ($row != null)

{
      $_SESSION['username'] = $row['first_name'];
      header("Location: index.php");
      exit();
}

You might change these lines of code to this (just for testing purposes):

if ($row != null)

{
      $_SESSION['username'] = $row['first_name'];
echo "<PRE>" . var_dump($row) . "</PRE>";
/*      header("Location: index.php");
      exit();*/
}

Post the output of that.

matt.sisto · March 18, 2009

array(10) { [0]=>  string(1) "7" [1]=>  string(1) "1" [2]=>  string(7) "Malcolm" [3]=>  string(1) "X" [4]=>  string(0) "" [5]=>  string(0) "" [6]=>  string(19) "[email protected]" [7]=>  string(0) "" [8]=>  string(10) "0000-00-00" [9]=>  string( "password" }

pkSML · March 18, 2009

Here's the answer:

$row = mysql_fetch_row($result);

If you change that to mysql_fetch_array, you should get your desired results.

You can also change this line:

$_SESSION['username'] = $row['first_name'];

to this:

$_SESSION['username'] = $row[2]; // assuming Malcolm is in the first_name column per your example
