//if($reg==1){
//$msg1="<font color=\"#FF0000\"><b>Your details have been added, please login</b></font>";
//}elseif($reg==2){
//$msg1="<font color=\"#FF0000\"><b>You have been successfully logged out.</b></font>";
//}

if(isset($_POST['submit'])){
if( empty($_POST['uname']) && (empty($_POST['upass']))){
header( "Location:Messages.php?msg=1" ); 
exit();
}
//transfer to shorter var
$n=$_POST['uname'];	
$p=$_POST['pwd'];

include('config.php');

$sql="SELECT * FROM customer WHERE uname='$n' AND pwd=MD5('$p')"; 
$query=mysql_query($sql) or die("Queryfailed:".mysql_error());
if (mysql_num_rows($query) != 0) { 

$mytime=time();
$mytime=date("H:i:s A",$mytime);
$_SESSION['time'] = $mytime;
$_SESSION['status'] = 'logged';
$_SESSION['username'] = $n;

header("location:welcome.php");
exit;
} else {
$_SESSION['status'] = 'not logged';
header("Location:Messages.php?msg=2" ); 
exit();
}
}

as you can see above there is a $first name...the firstname is stored in the table which is associated with that login id.

welcome page (page 2)

<?
session_start();
if ( empty($_SESSION['username'])){
header("location:default.php");
exit;
}

?>

There's a lot of code to look through for a vague problem.

On your second page, do print_r($_SESSION) and you will see all the session vars.

In your first script you do

$first_name = $_SESSION['first_name'];

But I never see you assign it INTO the session.

bhavin_85 · February 12, 2007

yep i tihnk thats the problem, how do i assign it to the session? bearing inmind that it isinformation which is in the same table as the login information so in effect i need the page to recognise the login id, then get the other information in that same table row...and print it on the second page

Jessica · February 12, 2007

You did it down here:

$mytime=time();

$mytime=date("H:i:s A",$mytime);

$_SESSION['time'] = $mytime;

$_SESSION['status'] = 'logged';

$_SESSION['username'] = $n;

$mytime=time();

$mytime=date("H:i:s A",$mytime);

$_SESSION['time'] = $mytime;

$_SESSION['status'] = 'logged';

$_SESSION['username'] = $n;

yea but those are not details from the same row in the table that has the login id...if you look at my previous post i explain what i mean...sorry u replied while i was editing my post thanks 4 the uber speedy replied though

Jessica · February 12, 2007

That is how you assign a variable to the session. Are you asking how to get the information from the table? Look at the mysql functions on php.net or read a tutorial here...

bhavin_85 · February 12, 2007

ok ive had a look on php.net and im not sure what i should be lookin for....how do i call the fields from the database? ??? do i need to run a query that returns all of the fields then use that? or does sessions give me the ability to do that?

sorry for askin the basic questions but im a total n00bie to php

Jessica · February 12, 2007

That's why I'm advising you to read a tutorial, like the ones on this site.

OR:

http://us2.php.net/mysql_query

The second example here: Example 1356. Valid Query

bhavin_85 · February 12, 2007

ive had a read of that stuff....am i right in sayin that to get the information i have to write an sql query that will get all of the fields from the database. Ok so now i only need to figure one thing out...i need to transfer my customer_id from the first page to the second so i can run the sql query on the second page by matching the customer id signed in with to the customer id in the table...so how would i bring the id from the first pag to the next?

Jessica · February 12, 2007

$p = md5($p);

$sql="SELECT * FROM customer WHERE uname='$n' AND pwd='$p'";

$result = mysql_query($sql);

if (!$result) {

$row = mysql_fetch_assoc($result);

$_SESSION['fname'] = $row['fname'];

}

bhavin_85 · February 12, 2007

cheers 4 that

had to tweak it abit so that it worked with my code

$sql="SELECT * FROM customer WHERE uname='$n' AND pwd=MD5('$p')"; 
$query=mysql_query($sql) or die("Queryfailed:".mysql_error());
if (mysql_num_rows($query) != 0) { 
$row = mysql_fetch_assoc($query);
$_SESSION['first_name'] = $row['first_name'];
