I'm trying to create an array to display the last 5 products a customer has viewed.
The array is a 2 dimensional array like below...
$RView= array(
array( ID => "1001", RefCode => "Ref_01", Name => "Name_01" ),
...
array( ID => "1005", RefCode => "Ref_05", Name => "Name_05" )
);
The array values are retrieved from the products recordset and is designed to function as follows when a customer visits a product page.
1. Page will check if a Session Array exists.
2a. If yes, an array variable is created from existing Session.
2b. If no, a new array is created.
3. Array will add the new product details.
4. Array will count if there are more than 5 existing products in the array.
5a. If yes, it will remove the oldest.
5b. If no, moves to step 6.
6. A Session is created/updated from the revised Array.
My current effort is attached below...
Many thanks for any help.
<?php
session_start()
// Get or Create Array
IF (isset($_SESSION['sessRView'])) {
$RView = ($_SESSION['sessRView']); }
ELSE {
$RView = array(array());
}
// Append currently viewed Product to Array
array(array_unshift($RView, $row_rsPrd['PrdID'], $row_rsPrd['RefCode'], $row_rsPrd['Name']));
// Check if more than 5 products exist in Array, if so delete.
IF (sizeof($RView) > 5) {
array(array_pop($RView)); }
// Update Session for next page
$_SESSION['sessRView'] = $RView;
// Display Array
for ($row = 0; $row < 5; $row++)
{
echo "<ul>";
echo "<li><a href='?PrdID=".$RView[$row]["PrdID"]."'>".$RView[$row]["RefCode"]."</a> : ".$RView[$row]["Name"]."</li>";
echo "</ul>";
}
?>
