Avoid Home Page Load after refresh from some other page using Jquery and PHP techniques

Hi I am using following techniques to Load different pages with menu bar. When ever i click on any menu bar button it loads the pages without page refresh. But When I am in any other page except Home Page and i want to refresh or submit that page it again loads Home page.

Menu

<ul id="navigation"> <li><a href="javascript:loadContent(1);">Home</a></li> <li><a href="javascript:loadContent(2);">Services</a></li> <li><a href="javascript:loadContent(3);">About</a></li> <li><a href="javascript:loadContent(6);">Contact</a></li> </ul>

Jquery PageLoad

function loadContent(id) { $("#pagehandler").load("loadpage.php?pageid="+id+""); }

Page Load in Body

<div id="pagehandler"></div>

php file code

switch($cOption) {
    case 1: 
        $extra = 'home.php';
        header("Location: http://$host$uri/$extra"); 
        break;
            case 2:
        $extra = 'Services.php';
        header("Location: http://$host$uri/$extra"); 
        break;
       开发者_Go百科     case 3:             
        $extra = 'about.php';
        header("Location: http://$host$uri/$extra"); 
        break;


    default:
        echo 'Whoops, didn\'t understand that option: <i>'.$cOption.'</i>';
}

?>`

From this sample code you can understand the process of code execution. When i click ony menu button.

How can i refresh any page using f5 with loading home page.

It seems that you the first branch of the switch statement is executing. Have you verified this?

I would have the home redirect be the default and only check for known values that are no home.
