[Resolved] Sessions---Please!

magic-chef

I am having problems implementing sessions on my site. Here's where I am.

I want to set certain session vars on site entry if it is the beginning of a session. I have read that $SESSION can have security problems if the initial values are not checked and set correctly. Something about isset or empty checks. I forget which one is the most reliable. My next problem is related to some data (2 arrays) I need to have access to for about 3 pages. I wanted to store them in $SESSION but thought it would be good to "register" them. It seems this creates a problem for me.

I need sessions to control access to various pages & as I explained above to hold some arrays for a while. I need help getting my arms around this one...

heres what to do:

at the start of every page you must have:

session_start();

If storing quite small arrays then I would suggest imploding the array so it's just a single string.

e.g.

<?

$array[0] = "none";
$array[1] = "alpha";
$array[2] = "beta";
$array[3] = "gamma";

?>

<?

$array = array('none', 'alpha', 'beta','gamma');

?>

would be turned into:

none|alpha|beta|gamma

This can be done by using the implode function:

<?

$array_stored = implode("|", $array);

?>

then register that array into a session:

<?

session_register("array_stored");

?>

for more than one, seperate with a comma ("one","two");

NOTE: It wont work if you include the '$' in session_register

setting up page links

Every internal site link (that needs session access) must add this at the end of each link:

filename.php?PHPSESSID=<? echo $PHPSESSID; ?>

returning array to it's original form

using explode on the page you want to display the array to it's original form!

(remember to add session_start(); to the top of the page

<?

session_start();

$array_stored = $_SESSION['array_stored'];

$array = explode("|", $array_stored);

// now you can echo session values

echo $array[1]; // will display 'alpha'

?>

I HOPE THIS HELPS!!
