single ecart var to hold multiple values?

I have a item that can be chossen for more than one location and they are choosen from a group of checkboxs which I just made a simple loop for :

<?php do { ++$i?>

<input <?php if (isset($_POST['Pub_'.$i])) {echo "checked=\"checked\"";} ?> type="checkbox" name="Pub_<?php echo $i;?>" value="<?php echo $row_rs_member_list['ID'];?>" /><?php echo $row_rs_member_list['PUB_NAME']; ?><br />

<?php } while ($row_rs_member_list = mysql_fetch_assoc($rs_member_list)); ?>

so from this I can end up with 1 to 20 or more values "Pub_1=123&Pub_3=124" and so on... I wanted to know if I could store this sting in a ecart column in this format?

I tried to make it sort the value in an array but it would not store it correctly

do {
if (isset($_POST['Pub_'.++$iurl])) {
$Publist[] = $_POST['Pub_'.$iurl];
}
} while ($iurl != $totalRows_rs_member_list); $iurl = 0;

if you name the checkboxes using the same name and "[]" at the end, the values will already be stored in an array
<input type="checkbox" name="Pub[]" value="<?php echo $row_rs_member_list['ID'];?>" />

you can then convert the array to a comma separated list using the implode function:

<?php echo(implode(", ", $_POST['Pub'])); ?>

Hi Jason
Hi Jason, I finely got it to work, thanks for pointing me in the right direction used this eventually.

// page post defualts
$ProductPubList = implode(", ", $_POST['Pub']);
$SelectedPubList = explode(", ", $ProductPubList);

// load item selected options from cart contents sent from viewcart page
$array1 = $LWV->DisplayInfo("Publist");
$pubarraylist = explode(", ", $array1)

<?php if ((in_array($row_rs_member_list['ID'], $SelectedPubList, TRUE)) ||(in_array($row_rs_member_list['ID'],$pubarraylist,TRUE))) {echo "checked=\"checked\"";} ?> type="checkbox" name="Pub[]" value="<?php echo $row_rs_member_list['ID'];?>" />

glad to hear you have it working.
