by default, the add to cart behavior on your pages will save the page name in a session variable, and that session is used in the continue shopping behavior.
on the cart page, the continue shopping code will look like:
<?php
// WA eCart Continue Shopping
if (isset($_POST["eCart1_Continue_100"]) || isset($_POST["eCart1_Continue_100_x"])) {
$Redirect_redirStr="";
if (true && isset($_SESSION['WAEC_ContinueRedirect'])) {
$Redirect_redirStr=siteToPageRel($_SESSION['WAEC_ContinueRedirect']);
}
if ($Redirect_redirStr != "") {
$eCart1->redirStr = $Redirect_redirStr;
}
$eCart1->cartAction = "Continue";
}
?>
if you don't want to use the session and would rather hard code the redirect, change the following line in the continue code block:
$eCart1->redirStr = $Redirect_redirStr;
to:
$eCart1->redirStr = "product_results.php";
