Call a specific PHP function with AJAX?

Please support our JavaScript / DHTML / AJAX advertiser: PostgreSQL or MySQL? Compare and contrast the two most popular open source databases

Call a specific PHP function with AJAX?

Dec 23rd, 2008

Hi guys,

I was wondering if it was possible to call a specific PHP function using AJAX instead of calling a whole page. An example:

 Help with Code Tags 
 JavaScript / DHTML / AJAX Syntax (Toggle Plain Text) 
function MakeRequest()
{
	var xmlHttp = getXMLHTTP();
 
	xmlHttp.onreadystatechange = function()
	{
		if(xmlHttp.readyState == 4)
		{
			document.getElementById('provinceDiv').innerHTML =
			xmlHttp.responseText;
		}
	}
 
	xmlHttp.open("GET", "FindProvinces.php", true);
	xmlHttp.send(null);
}
function MakeRequest()
{
	var xmlHttp = getXMLHTTP();
 
	xmlHttp.onreadystatechange = function()
	{
		if(xmlHttp.readyState == 4)
		{
			document.getElementById('provinceDiv').innerHTML =
			xmlHttp.responseText;
		}
	}

	xmlHttp.open("GET", "FindProvinces.php", true);
	xmlHttp.send(null);
}

I already have a PHP function (in a class) that retrieves the provinces/states from the database based on the country. I was wondering if it was possible to call this function instead of having to make a new file (in this case FindProvinces.php) that calls the function. Thanks in advance.

I am sure PHP has some sort of MVC architecture implementation wherein the controller handles the requests and delegates it to an appropriate entity.

 Help with Code Tags 
 javascript Syntax (Toggle Plain Text) 
// Here /operations is mapped to a PHP file which acts as a 
// controller and performs the delegation activity based on
// the operation requested, here, find-provinces
xmlHttp.open("GET", "/operations/find-provinces", true);
xmlHttp.send(null);
// Here /operations is mapped to a PHP file which acts as a 
// controller and performs the delegation activity based on
// the operation requested, here, find-provinces
xmlHttp.open("GET", "/operations/find-provinces", true);
xmlHttp.send(null);

Maybe posting this PHP related query in the PHP sub-forum might bring out some good responses since this seems more like a server-side url mapping/configuration issue.
