hey lewis!

first see the examples how to setup the PEAR_AJAX server.php and to start
the class. when you got this, you should end up with a class you start via
the server.php. in this class you can put functions to interact with your
form. i show you an example how i made this for a project from myself...

in this func a user uses a radiobutton so re-sort the search results

class ajaxclass {

function ajaxclass(){
}

function updateorder($order, $pageID){

if(!empty($_SESSION['query'])){

require_once 'HTML/AJAX/Action.php';
$objAction =& new HTML_AJAX_Action();

if($order=='zuname'){
$_SESSION['query']['order'] = 'zuname';
}

if($order=='company'){
$_SESSION['query']['order'] = 'company';
}

if($order=='lastEdit'){
$_SESSION['query']['order'] = 'lastEdit';
}


if($_SESSION['query']['output']=='adressen'){
$output = utf8_encode(queryOutputAdresses($_SESSION['query'],$pageID));
}else{
$output = utf8_encode(queryOutputMarketing($_SESSION['query'],$pageID));
}

$objAction->assignAttr('result', 'innerHTML', $output); // 'result' is
the ID of an html element
return $objAction;
}

}


on the HTML side i call this func with:
onclick="ajaxclass.updateorder('company','$pageID');"

and the ajax output goes to

src="server.php?client=all&stub=ajaxclass">




sorry my english is not the best and this example might not be perfect
either, but maybe you get a glimpse how to use PEAR_AJAX

have fun,
superfly

and the ajax output goes to
src="server.php?client=all&stub=ajaxclass">
 var remote = new ajaxclass({});

some parts of my posts didnt get throu the nable security and i think i posted a bug :(


< h e a d e r >
< script type="java.... src="sever.php..." >
< script type="java.... >
var remote = new ajaxclass({}); // we need to start the class too

the js eventcall should then be -> onclick="remote.updateorder('company','<?=$pageID?>');"

now it should work ;)
