// 4. "icon2" - item icon (mouseover state)
function getMenuItems()
{
$jsItems = '';
// Select all records from table "menuTable"
$allItems = mysql_query('SELECT * FROM menuTable;');
// Extract items data from database and build Javascript code for menuItems
while ($itemData=mysql_fetch_array($allItems))
{
$jsItems .= '["'.$itemData['text'].'", "'.$itemData['link'].'", "'.$itemData['icon1'].'", "'.$itemData['icon2'].'"],';
}
// Return Javascript code
return $jsItems;
}
?>
<script>

Q: Could you also tell me where I should place the images I wish to use in the menu, eg arrows. When I select an image to use they are not appearing in the preview, or when I launch deluxe-menu.html?
A: Please, check images paths within data .js file.
For example, if you have data.js file here:
c:/website/data.js
and your images are stored here:
c:/website/images/
you should set image name so (for example):
var arrowImageMain = ["images/arrow1.gif", "images/arrow2.gif"];
If you use Tuner, you should save data .js file before you'll selectimages. When you save .js file it means that you set a root directoryfor the project, so Tuner can make all selected images with relativepaths.
