AJAX PHP variable request

[webnoob]

I have a graph that i need to be dynamic in the sense that a user would click a checkbox and select which info will be displayed. I can do this using php, but i want a seamless transition done. My thoughts are AJAX SO basically i need a way to send a a request to a php page lets say graph.php with a variable set liek so:

graph.php?id=1

Can someone point me in the right direction regarding this please, i presume i can use the onCheck on the check box and have a small function to handle the ajax request, Just to summerize:

Checkbox Clicked --> Request to php page with a variable set --> Return the php page.

Thanks for the help in advanace

Hi There,

I just had a similar issue and there are a lot of "packages" out there that can help you do this.

I found one called PHPLiveX that is very lightweight and does only exactly that - executes a PHP function and returns the return value for you to write with JavaScript.

There are a few examples included with the package - take a look:

yeah, lots of Ajax libraries out there to help you out.
Check out http://mootools.net
and you can do something like

//xhtml
<input type='checkbox' value='foo' onclick="
new Ajax('http://yoururl/ajaxpage.php', {method:'post',postBody:'id='+this.value,onComplete:ajaxCallback{).request()" />

//js
//the php page should return back xml
function ajaxCallback(obj) {
    this.transport.responseXML.getElementsByTagName('bar')
    ...
}
