Q: I’d like to know how to populate the navigation bar menu from a database?
A: Please, see the example of .php file.The content of .php file depends on your database structure.
<?php
// The example for PHP/MySQL.
// MySQL database has the table "menuTable" that contains data for menu items.
// The table has the following fields:
// 1. "text" - item text
// 2. "link" - item link
// 3. "icon1" - item icon (normal state)
// 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>
var menuParam1 = value1;
var menuParam2 = value2;
var menuParam2 = value2;
...
var menuItems = [
// Write Javascript code for menu items
echo getMenuItems();
?>
];
</script>
Q: I couldn't understand where to put copied SE Friendly code for the dhtml top menu.
A: You should generate search engine friendly code and install it on yourpage in the beginning of the BODY tag.
JavaScript Tree Menu is a search engine friendly menu since v1.12.
To create a search engine friendly menu you should add additional html code within your html page:
<div id="dmlinks">
<a href="http://deluxe-menu.com">menu_item_text1</a>
<a href="http://deluxe-tree.com">menu_item_text2</a>
...etc.
</div>
To generate such a code use Deluxe Tuner application.
Run Tuner, load your menu and click Tools/Generate SE-friendly Code (F3).
Q: I am using cross frame menu dropdown. I have three frames: Top, Left and main (middle).
I am using the script and data from your sample file; it works fine. Only problem is submenu is offset to the right. It does not show up exactly down below the top menu.
What could be the problem?
A: JavaScript Tree Menu doesn't work correctly (incorrect submenu position) if youhave complex frame structure.
The problem is in a structure of your frameset.
Mozilla browsers can't determine absolute coordinates for a frame, so submenus drop down with an offset.
You should create, for example, the following frameset structure:
--|------------
| menu
--|------------
|
| submenus
|
Now a top row has 2 columns and all browsers can determine a width of the 1st column in the second row.
You should write init function in the following way in that case:
dm_initFrame("mainframe",1,3,0);
Q: I place all of my files in folders. If I want the Deluxe menu to work I have to have the Deluxe menu saved in each folder for it to work with the files inside those folders.
A: There is no need to copy al files for the menu in each folder.
To install the menu you can use such paths:
<script type="text/javascript"> var dmWorkPath = "../menudir/";</script>
<script type="text/javascript" src="../menudir/dmenu.js"></script>
You can use additional parameters to make menu paths absolute:
var pathPrefix_img = "http://domain.com/images/";
var pathPrefix_link = "http://domain.com/pages/";
These parameters allow to make images and links paths absolute.
For example:
var pathPrefix_img = "http://domain.com/images/";
var pathPrefix_link = "http://domain.com/pages/";
var menuItems = [
["text", "index.html", "icon1.gif", "icon2.gif"],
];
So, link path will be look so:
http://domain.com/pages/index.html
Images paths will be look so:
http://domain.com/images/icon1.gif
http://domain.com/images/icon2.gif
Please, try to use these parameters.
