This is a hack to allow the current menu and sub menu selection to be high-lighted.
It could also form the base for a breadcrumb block.

I hope this is the right forum.

The idea is to add a .current var to the $blocks array that is used by system_block_mainmenu.html.
Smarty logic can then be used to make the current selection look different.

A bread crumb block could loop through the $blocks the way system_block_mainmenu.html does and use only the .current links to make a bread crumb trail.

limitations:
If you have a module as your default page, the home link will not be high lighted.

3 files are changed:
Changes required to modules/system/blocks/system_blocks.php
Changes required to system_block_mainmenu.html
Changes optional to /xoops.css to indicate the current menu choice.

system_blocks.php: (Only the function b_system_main_show()
is changed. Here it is.)

// GPP added .current to module and sublink allow color menu and bread crumbs
// NB:: requires changes to system_block_mainmenu.html!

/* GPP seems to generate the info for the menu

Thanks - Grant.

this seems like exactly the thing i'm looking for

but could you please give a little more indication on how i can display a breadcrumb using this code? that would help a lot, thanx!

edit: woops, something went wrong, sorry for the double post, my bad.

The best solution would be create a new block for the breadcrumb.
But, if you don't need the side menu, you could use a different system_block_mainmenu.html and the menu block will make a bread crumb.
WTF is up with the preview here ???
(warning I'm thinking off the top of my head and haven't tried this code:)

<{$block.lang_home}> <{foreach item=module from=$block.modules}> <{if ( $module.current == 1 )}> <{$module.name}> <{/if}> <{foreach item=sublink from=$module.sublinks}> <{if ( $sublink.current == 1 )}> <{$sublink.name}> <{/if}> <{/foreach}> <{/foreach}>

thanks a lot, gppetersen

i'm very busy with other stuff at the moment, but i'll definitely try it as soon as i can

cheers!

it doesnt work and i'm afraid i'm too big a xoopsn00b to understand why

i updated system_blocks.php (Only the function b_system_main_show())

and then tried adding the code of your last post in a template (maybe that isn't what you meant?).

Did this get fixed/working?

Would love to have breadcrumb capability

Did you update module System after editing system_blocks.php ?!

Quote:
Just dirty thinking...
If you define current as string (f.e "0|1"), you can have slightly modified CSS after it, and use instead of current
td#mainmenu pair like
td#mainmenu0
td#mainmenu1
and have CSS-classes in template changed with smarty-var accordinly

BTW - I'll try your idea in my new theme

Where is this found?

system_block_mainmenu.html

xoops 2.0.10

Many thanks
