cant carry variable to another page

[optiplex]

i cant carry the value of $t_nick to another page... 

<?php
ob_start();
$host="localhost"; // Host name 
$username="algebraf_admin"; // Mysql username xx
$password="algebraforex_123"; // Mysql password 
$db_name="algebraf_account"; // Database name 
$tbl_name="members"; // Table name

// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

// Define $t_nick and $t_password 
$t_nick=$_POST['t_nick']; 
$t_password=$_POST['t_password'];

// To protect MySQL injection (more detail about MySQL injection)
$t_nick = stripslashes($t_nick);
$t_password = stripslashes($t_password);
$t_nick = mysql_real_escape_string($t_nick);
$t_password = mysql_real_escape_string($t_password);

$sql="SELECT * FROM $tbl_name WHERE t_nick='$t_nick' and t_password='$t_password'";
$result=mysql_query($sql);
// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $t_nick and $t_password, table row must be 1 row

if($count==1){
// Register $t_nick, $t_password and redirect to file "list_details.php"
session_register("t_nick");
session_register("t_password"); 
//echo $t_nick;
//exit;
header("location:list_details.php");
}
else {
echo "Wrong Username or Password";
}

//ob_end_flush();
?>

 

from above, if t_nick and t_password is true, the page will direct to list_details.php... the problem occurs at list_details.php. cannot display any data from database because the t_nick is not carry along.

You aren't calling session_start()

<?php

session_start();

i've call session.. here the coding

session_start();
if(!session_is_registered(t_nick)){
header("location:login.php");
}

 

and still doesn't work...  :'(

You need to update your knowledge of how sessions work.

 

This is what php.net has to say about the function session_register()

 

This function has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 6.0.0. Relying on this feature is highly discouraged.

 

So there you go. Do it like so:

 

session_start(); //place this function at the top of your scripts - it's a good habit to get into.

//now say I want to create a session variable called "name" - there's no need for session_register()
$_SESSION['name'] = "Wayne";

 

See? Easy as a Bangkok hooker.

session_register() is deprecated. Use $_SESSION['variable'] instead.

Nice!

If you are not familiar I suggest reading through the Session Handling section at php.net

 

http://us.php.net/manual/en/book.session.php

 

The examples section will be truly helpful in understanding how to pass variables with sessions.

Nice! 

 

ermmm.. ive put this..

 

$_SESSION['t_nick']='$t_nick';

 

but.. still facing the same problem..

[flyhoney]

$_SESSION['t_nick']='$t_nick';

 

That's just going to set the session variable $_SESSION['t_nick'] equal to the LITERAL string '$t_nick'.

 

Are you using session_start() ?

[optiplex]

i've remove session_start();

still blur  :'(

 

[9three]

On top of your page it MUST have session_start() otherwise $_SESSION will not work properly.

 

So do session_start() THEN set your variables into your session.

 

session_start();
$_SESSION['name'] = 'FirstName!';

ermm.. doesnt work at all ...
