Best way to do AJAX

[standerby]

Hi,

I am working on a web page, which has check box, radio button, slider, etc. What I want to accomplish is to display some data retrieved from database using the criteria enforced by those controls. I am using MDB2 for database accessing and it works great. My question is what method I should use for HTML_AJAX to interactive with customer. For instance if a customer check a checkbox it will make a query to database and update the content div.

Thanks,
Lewis

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 <div id="result></div>

in the header area i got
<header>
<script type="text/javascript" src="server.php?client=all&stub=ajaxclass"></script>
 <script type="text/javascript">var remote = new ajaxclass({});</script>
</header>


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
