Help with $_session[points]

noswad · May 18, 2006

Hi.

I have a page using sessions to obtain data from my database.

For example -

session_start();
echo("Your balance is $_SESSION[points] ");

So if a user has 10 points, it will display 'Your balance is 10'.

If the session picks up nothing in the database (I mean an empty field, not 0 points) is there a script I can implement so that the page doesnt display an empty line.

Thanks for reading and I will donate all my NP$ to any one who finds a solution!

Something like this?

PHP:

<?php

session_start();

if($_SESSION['points'] == '')
{
  echo '';
}
else
{
  echo 'Your balance is '.$_SESSION['points'];
}

?>

And no need for the NP$

Instead of $_SESSION['points'] == '', I would use !isset($_SESSION['points'])

Thanks for the replies. I think I may need to adapt on what I originally posted.

Basically, in the example below, if the field in the database for the session 'used' is empty I want 'Points Left:' to move up one line on the web page.

session_start();
echo("Points: $_SESSION[points] ");
session_start();
echo("Used: $_SESSION[used] ");
session_start();
echo("Points Left: $_SESSION

");

At the moment, because the session 'used' is empty my page is displaying like this:

Points: 3

Points Left: 3

Where as I want it to display like this:

Points: 3
Points Left:3

And then when the user finally uses 1 point, I will update the databse so that the page auto displays like this:

Points: 3
Points Used: 1
Points Left: 2

Thanks again and sorry for not been clear initially

PHP:

session_start();
echo "Points: ". str_replace("\n","",str_replace("\r","",$_SESSION[points]));
echo "Used: ". str_replace("\n","",str_replace("\r","",$_SESSION[used]));
echo "Points Left: ". str_replace("\n","",str_replace("\r","",$_SESSION[left]));
