NICE MENUS UPGRADES
|
|
3
|
===================
|
|
4
|
5.x, 6.x-1.x ---> 6.x-2.x
|
|
5
|
-------------------------
|
|
6
|
There is an update hook and you should run update.php to get things moved
|
|
7
|
around properly. Aside from the minor database changes, there are a number of
|
|
8
|
things you should be aware of, especially in light of any customizations you
|
|
9
|
may have made.
|
|
10
|
|
|
11
|
THEME FUNCTIONS:
|
|
12
|
The theme functions have all been RENAMED to be more in line with Drupal
|
|
13
|
standards, so if you are overwriting the functions in your theme's
|
|
14
|
template.php or calling the functions anywhere in your theme, you should
|
|
15
|
update the function names. The old functions were called theme_nice_menu_* and
|
|
16
|
the new ones are theme_nice_menus_*, with an "s" to match the module name.
|
|
17
|
|
|
18
|
NEW JAVASCRIPT:
|
|
19
|
The old JS has been completely removed and replaced with JS that uses the
|
|
20
|
Superfish jQuery plugin. It now fires for ALL browsers by default, unless you
|
|
21
|
turn the JS off in your settings at Administer > Site configuration > Nice
|
|
22
|
menus (admin/build/nice_menus). If you had "Enable IE support" checked under
|
|
23
|
older versions of NM, then the new JS will be on by default. If it was
|
|
24
|
unchecked in your older version, then the update will turn JS off for you by
|
|
25
|
default. If you turn JS off on the site (or a visitor comes without JS
|
|
26
|
enabled), IE6 will no longer get the dropdown effect, but all other browsers
|
|
27
|
will fall back to CSS-only dropdowns.
|
|
28
|
|
|
29
|
CSS IDs and CLASSES:
|
|
30
|
The menu-$menuid ID has been changed to a CLASS to avoid invalid HTML when
|
|
31
|
displaying the multiple menus which use the same menu ID. If you have custom
|
|
32
|
CSS that depends on the menu ID then you need to change it to a class. For
|
|
33
|
example:
|
|
34
|
#menu-3 {color: #ff0};
|
|
35
|
would need to be changed to
|
|
36
|
.menu-3 {color: #ff0};
|
|
37
|
|
|
38
|
IE-Specific Class removed
|
|
39
|
The legacy "ie-over" class which was added for IE compatibility in the past
|
|
40
|
has been replaced with a generic, non-browser-specific, "over" class since
|
|
41
|
this is used by Superfish and should be general.
|
|
42
|
|
|
43
|
5.x ---> 6.x
|
|
44
|
------------
|
|
45
|
Due to the menu system changes from 5 to 6, when you upgrade Nice Menus, your
|
|
46
|
blocks will "forget" what menu they were set to. So take note of the blocks
|
|
47
|
and menu settings prior to upgrade, then reset them after the upgrade. See the
|
|
48
|
issue at http://drupal.org/node/524688 for more information.
|
|
49
|
|
|
50
|
|
|
51
|
4.7 ---> 5.x
|
|
52
|
------------
|
|
53
|
The CSS class has changed to change the underscore (_) to a dash (-)
|
|
54
|
The 4.7 version of class="nice_menu" is now class="nice-menu" in version 5.
|
|
55
|
You will need to adjust any Custom CSS you have added to account for this.
|
|
56
|
The default CSS that comes with nice_menus uses this new convention already.
|
|
57
|
|
|
58
|
Also note that the layout CSS for the module has been broken out into a
|
|
59
|
separate CSS file (nice_menus_default.css). You have the option of replacing
|
|
60
|
this file by creating a separate customized CSS file, and overriding the
|
|
61
|
default CSS file at Administer -> Themes -> Configure -> Global settings ->
|
|
62
|
"Path to custom nice menus CSS file".
