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: Now I wonder what I have to do in my script to make dhtml sub menu be displayed horizontal instead of vertical. I want them to display vertical be left - aligned and be shown by a white Background. How can I achieve this?
A: You should set the following parameters:
var smColumns=0;
var smOrientation=1; //horizontal orientation of submenus
set white backcolor for submenus
["itemWidth=60px","itemBackColor=#FFFFFF,#FFFFFF","itemBorderWidth=0","itemBorderStyle=none,",
"itemBorderColor=#FFFFFF,", "fontColor=#404040,#404040","fontDecoration=none,underline"],
Q: Is there any way of setting the height of individual items in a vertical menu as I need to have some buttons bigger than others.
A: You can use <br> tags in the item text.
For example:
["Samples<br>Samples","", "", "", "", "", "", "", "", ],
Q: The menu has a problem with newlines. The menu builds correctly (layout ok) but when pressed on the button nothing happens
At some point, in the DHTML menu, we have the following in the javascript:
var menuitems = [
["|Print HTML","javascript:alert('HTML print: Only the 7 most recent orders on the screen \n will be printed because of space limitations on paper.');printResult('4'); ","","", ,"_parent",,] ]
As you can see we have a newline (\n) between the words "screen" and "will". But when we click on the button nothing happens. If we remove the newline and we click on the button then we first get the alert box. After pressing the OK button the function printResult is called.
Is there any way for us to still use the newline character in the menuItems variable?
This can be easily reproducible. That's why I haven't made an example.
A: Try to write in the following way \\n:
["|Print HTML","javascript:alert('HTML print: Only the 7 most recent orders on the screen \\n will be printed because of space limitations on paper.');printResult('4'); ","","", ,"_parent",,]
