Jernx

Guys,

Please help me. I am testing something. I have 3 fill in fields and on page 3 I want to show all the results. Im trying to remind the result in sessions, but is only saves the last one. Can you please help me how to save the variables in the session? Underhere my script:

<?php
session_start();
$SESSION['paginanummer'] == '0';
if (isset($POST['getal1']))$SESSION['$getal1'] = $POST['getal1'];
if (isset($POST['getal2']))$SESSION['$getal2'] = $POST['getal2'];
if (isset($POST['getal3']))$SESSION['$getal3'] = $POST['getal3'];
?>

$_SESSION['paginanummer'] == '0'; is making a comparison, not an assignment. I think you mean:

$_SESSION['paginanummer'] = '0';

Hi J_70,

No, cause if I use $_SESSION['paginanummer'] = '0' nothing works anymore. With == '0' it is available to go through all field without filling in something.

j_70

When I run you page, I only see one data entry field. Give your switch statement, I would only expect to see one since $_SESSION['paginanummer'] does not appear to be set anywhere. Where / how are you setting this session variable?

Please use the board's [noparse]
[/noparse] BBcode tags when posting PHP code as it makes your code much easier to read and analyze. You should go back now and edit your post to include these tags.

Rather than playing guess-and-check with programming syntax, what are you trying to do? If you are trying to assign the value of 0 to the $SESSION['paginanummer'] variable, then == is the incorrect operator - use =.
This code:
```
$_SESSION['$getal1'] = $_POST['getal1'];
```
seems highly suspicious. You do realize that the index you're using is $getal1, that is, a literal dollar sign, followed by "getal1", right?
Where are $getal1, $getal2, etc. ever defined?
