Session data

[Anon]

I am running into a small problem with apending data to my sessions.

When adding only 1 set of data it works great!

output looks like this:
list_no|i:2;USER_NO|s:5:"35438";SELLERTYPE|s:5:"Owner";NAME|s:8:"45674576";URL|s:5:"76476";DURATION|s:7:"90 Days";LISTINGS|s:1:"C";TYPE|s:4:"Sale";PRICE|s:4:"4567";STARTPRICE|s:4:"4576";BIDINC|s:4:"4567";DESCRIPTION|s:10:"4567457647";PAY|a:1:{i:0;s:4:"Visa";}

My problem is, that the user has the option to add more than one of these entries, I can not figure out how to get them to stack.

Meaning having list_no 1 (with data) and list_no 2 (with data).

Here is the line of code that I have tried so far.

if(!isset($list_no)){
$list_no = 1;
session_register(list_no);
} else {
$list_no++;

}

for($i = 1; $i < $list_no; $i++){
	session_register(USER_NO);
	session_register(SELLERTYPE);
	session_register(NAME);
	session_register(URL);
	session_register(DURATION);
	session_register(LISTINGS);
	session_register(TYPE);
	session_register(PRICE);
	session_register(STARTPRICE);
	session_register(BIDINC);
	session_register(DESCRIPTION);
	for($i = 0; $i < count($PAY); $i++){
	$pay2[] = $PAY[$i];
	session_register(PAY);	
		}

	}

This obviously isnt working, all it is doing is changing list_no to ++ from previous and is not stacking the data.

Any help is appreciated.... i am a bit sick at the moment, maybe that has something to do with my problem 😉

Well, you have a number of problems here.

1. You don't say where the variable values are coming from, so I'm going to guess they are coming from form fields. If that is the case, you are simply setting the same values in the session over and over again in your loop since the variable names never change.

2. <i>$list_no</i> is itself only a single variable name that never changes, so the best you can do is replace its value every time.

3. You use the same loop control variable <i>$i</i> in two nested loops. Bad. Can cause big headaches.

4. I can't tell what you are trying to do with $PAY; you move the contents in $pay2 but never do anything else with them.

What you need to do if you want to stack these "lists" is to put them into a two dimensional array:

=====================
if (!is_set($myLists) {
&nbsp;$myLists = array();
&nbsp;session_register('myLists');
}

$numLists = sizeof($myLists);
$curListIdx = $numLists +1;

$newData = array{};
$newData['USER_NO'] = $USER_NO;
$newData['SELLERTYPE' = $SELLERTYPE;
$newData['NAME'] = $NAME;
$newData['URL'] = $URL;
// rest here

$myLists[$curListIdx] = $newData;

That will store all the entries in a multidimensional array called $myLists in the current session. Each time they add one and press 'SUBMIT', it will tag a new array onto the end of $myLists with its values. When you want the data later, you can loop through the array and retrieve all the data.
