NAVIGATION
View submenu conditionally
I put together a combined horizontal and vertical navigation, the vertical (sub) menu will be displayed only when actually sub-menu items are available (this is for example the case on the product pages, but not at home).

You can not automate everything within a CMS!
Some menu solution can be implemented only by custom logic.
But it's important - if possible do NOT use inline PHP. In your case it goes as follows:
In the template, add to the area where the vertical menu is to appear
[Note: All the “numbers” are levels of structure IDs]
Create a new file navi_left_right.php in template/inc_script/frontend_render/.. and fill in the following code:
{VERTMENU}
<?php // ---------------------------------------------------------------- // obligate check for phpwcms constants if (!defined('PHPWCMS_ROOT')) { die("You Cannot Access This Script Directly, Have a Nice Day."); } // ---------------------------------------------------------------- // Simple "View submenu conditionally" // Forum: http://forum.phpwcms.org/viewtopic.php?p=90950#p90950 // Autor: Oliver Georgi 2007/08/26 // ---------------------------------------------------------------- $_vertmenu = ''; if(isset($LEVEL_ID[1])) { $_vertmenu = trim( buildCascadingMenu( 'F,' . $LEVEL_ID[1] . ',' ) ); // this is exactly the same as {NAV_LIST_UL: F,start_level_id, } // but built with php function behind if( $_vertmenu ) { $_vertmenu = '<div class="menu">' . $_vertmenu . '</div>'; } else { $_vertmenu = ''; } } $content['all'] = str_replace( '{VERTMENU}', $_vertmenu, $content['all'] ); ?>
Use {VERTMENU} on the site in the template where you want to appear the result….
