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: The menu is very large and I am concerned about load speed.
Does the ajax like technology just load the top tabs and then only the sub menus if they are clicked? I have clicked true and added 5 as there are 5 submenus but it does not seem to make any difference.
What can I do to speed up the javascript onclick menu?
A: Check that you've set the following parameter:
var dm_writeAll=0;Q: Can I install the menu using my buttons? I might be able to do it if the buttons used only one image, but they use two images. One is light and the other dark.
I also have some questions:
1) Will the menu stay in view when the user scrolls down?
2) I'm not even sure I care if the menu stays in view, because I believe that is done using php and is not good for SEO. The file that the search engines see is index.html while the file that visitors see is home.php. I think it would be better for SEO to have a normal .html page. Are you able to do that?
A: See how you should make image-based menus: if item text is empty, icon fields will be used as item images.
For example:
["", "index.html", "menu1a.gif", "menu1b.gif", "Home Page"]
1) You should use floatable feature.
See the following parameter:
var floatable=1;
2) You can generate search engine friendly code using Deluxe Tuner:
"Tools/Generate SE-friendly Code".
Q: Is it possible to expand vertical collapse menu in a predefined way?
A: You can expand some items by default.
Add '+' sign before items text in that case:
["+Deluxe Tree: XP Style","", "deluxe-tree.files/xpicon1_s.gif", "", "", "XP Title Tip", "", "0", "", "", ],
["|Home","testlink.htm", "deluxe-tree.files/icon1_s.gif", "deluxe-tree.files/icon1_so.gif", "", "Home Page Tip", "", "", "", "data-new.js", ],
"Deluxe Tree: XP Style" item will be expanded by default in that case.
Use var texpanded=1; parameter to expand all menu items by default.
Use function dtreet_ext_expandItem (itemID, expand) API function to expand the specificmenu items dynamically:
