I have "bastelt" a navigation-tag with the following features:
- show only one menu level you want to see
- auto startlevel > shows sublevels. you can write startlevel and level count
- link to parent menu, yes or no, name of parent or diffrent name
- hide one ore more menus
- one style for navigation-tag or for every menu
- special style for active link and for back link
- separator between menus
I hope there are not so much mistakes in the script but I have tested and everything was working...
Latest Update: 15.03.2006, 22:30
- changed some code for valid html
- The active Link has now a 'id=current'
- I added a new parameter ($xtra_menu_style). It can be 0 or 1. When 1 and $start_level_name = 0 (auto), the "div" and "ul" "active" tag of every sub menu get a extra style (style name = $style + alias from parent menu). So it`s possible, that a dynamic sub menu can change the color or anything else depending from the parent menu.
Code: Select all
<?php
// parameter(9): {NAV_ANY_LEVEL:$start_level_name:$auto_start_level:$auto_level_depth:$back_link:$hide_level:$style:$xtra_menu_style:$xtra_li_style:$separator}
// $start_level_name: name of parent menu, 0=>auto, shows act level, string=>alias of parent menu
// $auto_start_level: startlevel from which menus are shown. only if $start_level_name <> 0, number=>number of startlevel >=0
// $auto_level_depth: count of shown levels starting from $auto_start_level. only if $start_level_name <> 0, number=>number of levels to show >=0
// $back_link: link to parent menu. only if $start_level_name <> 0, 0=>no link, 1=>link name is name of parent menu, string=>different name
// $hide_level: menus to hide. if more, separete with ",". 0=>no hidden menus, string=>alias of menus to hide
// $style: name of style for div,ul,li. string=>style name
// $xtra_menu_style: every menu (div, ul) get a style. only if $start_level_name <> 0, $style + alias of parent menu. 0=>no, 1=>yes
// $xtra_li_style: every "li" get a style. $style + alias of menu. 0=>no, 1=>yes
// $separator: separator between menus. 0=>no, string=>separator
// always write 0 for unused parameters
// style from active menu: $style + _active
// style from link to parent menu: $style + _back
// example: {NAV_ANY_LEVEL:mynavi:2:1:back:0:mystyle:0:0:|}
// standard (for starting and testing): {NAV_ANY_LEVEL:0:0:0:0:0:any_navi:0:0:0}
// installation: make a file ("reptag_nav_any_level.php") in "phpwcms_template\inc_script\frontend_render" and copy the script in the file
