KoolAjax - Great PHP Ajax FrameworkFullVersion 3.0.0.0 released on 10/22/2012

Request class is used for advanced users who find that our built-in callback and updatepanel are not enough and want to build a custom ajax request.

In above example, upon selection of customer, the customerNumber will be sent to server. At server-side, the orders of that customer will be queried and sent back to client-side in table format. At client-side, on receiving the response from server, the onDone event handle will be called to display out the result.

<?php
	require $KoolControlsFolder."/KoolAjax/koolajax.php";
	$koolajax->scriptFolder = $KoolControlsFolder."/KoolAjax";
	echo $koolajax->Render();
?>
<form is="form1" method="post">
	Select customer to view order details:
	<select id="cbbCustomer" onchange="select_customer()">
		<option value="">--</option>
		<?php
			$result = mysqli_query($db_con, "select customerNumber,customerName from customers limit 0,10");
			while($row= mysqli_fetch_assoc($result))
			{
				echo "<option value='".$row["customerNumber"]."'>".$row["customerName"]."</option>";
			}	
		?>
	</select>
	<div id="orderSummary" style="padding-top:10px;width:300px;"></div>
	<script type="text/javascript">
		function select_customer()
		{
			var request = new KoolAjaxRequest({
				method:"post",		
				url:"Process.php",				
				onDone:function(result){
					//Show orders of customers
					document.getElementById("orderSummary").innerHTML = result;
				}			
			});
			var _customerNumner = document.getElementById("cbbCustomer").value;
			if(_customerNumner!="")
			{
				request.addArg("customerNumber",_customerNumner);
				koolajax.sendRequest(request);				
			}
		}
	</script>	
</form>

<?php 
	require "../../../../Resources/config.php";	
	$db_con = mysqli_connect($dbhost,$dbuser,$dbpass,$dbname);
	$customerNumber = $_POST["customerNumber"];
 
	$result = mysqli_query($db_con, "select orderNumber,orderDate, status from orders where customerNumber=$customerNumber");
 
	echo "<table border='1'>";
	echo "<tr><th>Order Number</th><th>Order Date</th><th>Status</th></tr>";
 
	while($row=mysqli_fetch_assoc($result))
	{
		echo "<tr>";
		echo "<td>".$row["orderNumber"]."</td>";
		echo "<td>".$row["orderDate"]."</td>";
		echo "<td>".$row["status"]."</td>";
		echo "</tr>";				
	}
	echo "</table>";
	mysqli_close($db_con);
