Adding to array in session

[AndyW2387]

Hi
I'm quite a newbie and have been struggling with sessions (!)

What I'm trying to do is to add submitted values from a textfield (or ID number) to an array which is in a $_SESSION. ( It's for a book site where customers can click on buttons next to books that come up on a search, each book id is submitted into a session and then they can go to a form page which will have all the books they are interested in filled out automatically in a text area field - or at least that's the idea)

Anyway I can't get the session to "remember" the data submitted to the array between pages. At present there's just a simple test form with a textbox & submit button going to a processing page with the following code :

<?php
 
 
session_start();
 
$AddStuff = $_POST['TestText']; 
 
 
if(isset($_SESSION['stuff']))
 
  $stuff[] = $AddStuff;
 
else
 
  $stuff = array();
 
  $_SESSION['stuff']=$stuff;
 
$stuffNumber = sizeof($stuff);
 
 
?>
 

The array $stuff() never gets more than 1 and I think it should surely retain the data by adding elements on each submission ? What am i doing wrong and can someone help me out please ?

PS ( Apart from not increasing the size of he array the above works alright )

thanks in advance

Andy

Heya, Andy. Welcome to TSDN!

The easiest way to do this is to:

$__form =& $_SESSION['_FORM'];
foreach( $_POST as $_key => $_val )
{
    $__form[$_key] = $_val;
}
 

Note that we are copying to $_SESSION['_FORM'] instead of $_SESSION. This is to prevent a User from hacking the form and setting arbitrary session values.

Hi

Thank you for your reply. The problem is that I need to add items to an array. Let's say a user selects one book by clicking on the relevant button, they then select another book by clicking on its button and a third book by clicking on its button as well - you have 3 books or whatever the number selected is - there is a "CONTINUE" button to take you to the form which then fills out the "Books selected" text area automatically.

I need the ids or details of all 3 books to appear in the text area box. If it was just a question of one book at a time - I wouldn't bother wih sessions - I would just post - or rather send a GET request to a processing page and fill in the relevant stuff using that.
But that means the customer can only choose one book at a time which is a nuisance - and i thought i could use sessions and arrays to get around it.

Do you see my problem ?
