PHP And AJAX

I want to make signup from using php and ajax, can anyone help me with it? I am new to ajax so dont know how to do it.

Thanks

 

I like using jquery for ajax.

So you would want to look into using jquery and the .post and .get functions that it offers.

Jquery Code Example:
What you see here is when the button that has an id="logmein" is clicked it sends the textboxes with the ids of password and user to user_login.php. Then it requests a response and expects JSON to come back. If the php echos success=1 then the login is good and you can send them to the main page with their session information.

$("#logmein").click(function(){
	$.post("user_login.php",
	{
	user: $("#user").val(),
	password: $("#password").val()
	},function(data){
	if (data.success == 1){
	location.href= "user_index.php?user="+data.user+"&session="+data.session;
	}
	},"json");
	});

Code (markup):

In you php you would take the username and password posts and compare them to your database and then output your data in json format.

Example:

$jsonoutput = array('user'=>$user,'session'=>$session,'success'=>1);
echo json_encode($jsonoutput );

PHP:

Hope this helps

 

I agree, use a pre-developed library if you want the easiest Ajax entry point. Personally, I like prototype, but jquery, and mootools are also great libraries.

 

Learning jquery or mootools is definately the best way. I learned ajax the hard way, and libraries cut development time in half.

 

When I started learning aJax XAJAX php library was the easiest way to get started, it's pretty easy to use and does everything you will need.

Just read the tutorial on here: http://xajaxproject.org/
