[RESOLVED] Lost Session Array

StevenJ

I have started a session, and I add image id's to a simple 1 dimensionsal array. nothing complicated. as the sql executes in a do while loop, I add the image IDs to the array.

//create array
$search_result_array = array () ;
//register session variable
$_SESSION['search_result_array'] = $search_result_array ;

I know this works because I now echo the output to screen, and after it's complete do a

 echo count($search_result_array) ;

and get the correct number of entries in the array.

when I click on a link, on the page I an going to, I start the session as normal.

I then tried accessing the $_SESSION array variable and I get nothing.

when I do

count($_SESSION['search_result_array']) ;

on this page I get a count of 0?

So I printed out the session ID on both pages, and the session ID is the same?
HELP! please..........

Sayian

paste the results of print_r($_SESSION['search_results_array']) here so i can see them.

StevenJ

page1.php

if (!isset($_SESSION)) { session_start(); }
// create array
$search_result_array = array () ;
//add array to a SESSION variable
$_SESSION['search_result_array'] = $search_result_array ;

print_r($_SESSION['search_result_array']) . "SESSION<br />" ;

gives
Array ( )

print_r($search_result_array) . "<br />" ;

gives
Array ( [188] => 188 [189] => 189 )

so, it's clear that the $_SESSION array is empty BEFORE I go to the next page!

But I have set it up right in the above code?

STUPID ME! doh!

I was assigning the array to the $_SESSION variable before I had populated the array, therefore it was ALWAYS going to be empty.

I'll stick my dunces cap on now.

thanks very much for the tip to use

print_r($search_result_array)

many thanks
