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: A lot of things have come in between... Just a few more Q's before I order.
1)
At the bottom of the page you refer to below, there is a table showing the tmenuItems array, itemInd and " submenuInd ". But in the examples on the same page, the function "dtreet_ext_getItemIDByIndex" takes the arguments (menuInd, itemInd). Is the argument "menuInd" the same as "submenuInd" referred to in the javascript menu design??
2)
When I highlight an item on "onload" I need to expand that item's parent(s), right? What will happen to other, already expanded nodes when I do that? Will they still be expanded or collapsed?
A: 1) menuInd is the index of a tree menu on a page, >= 0.
First menu - menuInd=0
Second menu - menuInd=1
Third menu - menuInd=2
Fourth menu - menuInd=3
...
2) Yes, the already expanded nodes will be expanded.
Q: We're working on new website and including your html menu systems.
Here's what we're trying to do and it keeps giving us an error (using MS Frontpage for development):
1) We have created a single leftnav menu that will appear on all of the pages of our website.
2) We've created an html page called leftnav.htm that is only this menu. It works just fine when we preview within Frontpage. The leftnav.htm and all the menu .js files are in a unique folder within the site.
3) We then have a template page that is the base template for many of the pages on our website. There is a layout table in this template into which we do an Includepage to bring in the leftnav.htm. When we try to preview this page with the menu included, we get a script error that says "Object expected" on line #155 (the .js file only has 154 lines of code).
We're stuck. Is there a problem with how we're trying to implement the html menu systems?
A: It is possible that you'll have an error in the Frontpage's preview.
Try to open your page in browser. If you'll have the same error,please send send us a copy of your html pages (including .js files) and we will check it.
Q: The buttons show up just fine in IE, but not in the other browsers. I am using Frontpage for my html.
A: Your file names are incorrect.
For example, now you have:
Button gold side 2 NEW.GIF
Button purple side 2 NEW.GIF
Firefox and Opera cannot open a file with blanks in the name.
Please, rename your files, for example:
Button_gold_.GIF
Button_purple.GIF
Your menu will work fine.
