I lost my path to finding the solution and need help immediately. I have a php page called list.php which shows list of products with BUY icon on each product. Once the BUY button clicked, it will directing to action.php (which contain script to add into the database) and then return into the same page using header(location:list.php?id=$r[id_product]). I want to show a popup message "the product is now added to cart" after returned into the list.php. How to do that?

You can you
cookie
and after returning just check if there is specifiedcookie
or not and if there is, show message.However if you using
ajax
you don't need a cookie, just add pop-up function in ajax parsing function, something like thatfunction addToBasket(itemId) { var x = new XMLHttpRequest(); x.open('GET', '/ajax/action.php?add=' + itemId, true); x.onreadystatechange = function() { if (x.readyState == 4) && (x.status == "200") { var responseObj = eval('(' + x.responseText + ')'); if (responseObj.status == 0) window.alert('The product successfully added to your basket'); else window.alert('An error has occured during the processing the data. Please try again later'); } }; x.send(null);
action.php
code example<?php // ... $response = array('status' => 1); if (isset($_GET['itemId'] && $_GET['itemId'] != '') { $item_id = htmlspecialchars($_GET['itemId']); if (is_numeric($item_id) { put_in_table($item_id); $response = array('status' => 0); } } // output an Ajax response header('Content-Type: application/javascript'); echo json_encode($response); ?>
