Sample

This sample provides a simple demonstration of how you could handle the activation and removal of menu items based on some server side variable value, such as a variable that handles the user name of the logged in user.

Here's how the sample works:

When the page is first accessed the code completely removes the "Utilities" menu item from the toolbar and displays "not logged in" in the first item of the toolbar.
If you enter a name (it can be anything since the sample doesn't really check the entered name) the name will be displayed in the first menu item of the toolbar, the "Utilities" menu will become visible but the "DHTML Menu Builder" submenu will be disabled.
Finally, if you login using "root" (just enter root in the textbox and click Login), the "Utilities" menu will become visible and the "DHTML Menu Builder" item will become enabled.

Here's the code that does the magic:

<script language="javascript" type="text/javascript">

  dmbAPI_Init();

  // Since the DynAPI does not support items that have been disabled form within
  DHTML Menu Builder,
// we need to disable them here, using the API.

dmbAPI_setItemState(dmbAPI_getItemByCaption("UserName"),
false);

dmbAPI_setItemState(dmbAPI_getItemByCaption("|"),
false);

  var n;

  // Because we are going to be working with the UserName
  toolbar item it is a good idea

  // to store its id in a variable so, every time we need to reference it we
  can just

  // use the value in the variable.  

    var c = dmbAPI_getItemByCaption("UserName");

    // So, let's see if the server-side variable $UserName
    contains any data

<? if(!isset($UserName) || ($UserName=="")) { ?>

  // The variable contained no data, which means
that no one has logged in, 

  // so we're going to disable the Utilities menu. 

  n = dmbAPI_getItemByCaption("Utilities");

  dmbAPI_removeTBItem(n);

<? } ?>

// Let's check now if the user "root" has logged in

<? if($UserName != "root") { ?>

  // The user name variable does not match "root" so the root user is not logged in.

  // In this case, we need to disable the  "DHTML Menu Builder" menu. 

  n = dmbAPI_getItemByCaption("DHTML
    Menu Builder");

  dmbAPI_setItemState(n,
    false);

  dmbAPI_setColor(n, "#C8C8C8");

<? } ?>

  // Finally, let's display the current;y logged in user
    name 

    n = dmbAPI_getItemByCaption("UserName");

    dmbAPI_setCaption(n, "<?
    echo (isset($UserName) && $UserName!="")?$UserName:"(not logged in)"; ?>");

</script>
