Code Snippet: breadcrumb showing or not showing 1st level/or single menu items

[swagmani]

Hi Matthias,

did you try it with a simply show_menu2 call? Look at the dokumentation of show_menu2, I'm pretty shure you can reach this with only one single line in your template, wich is much more better as to add whole functions in the template.

I did look at the docs for 'show_menu2', there was 2 examples of breadcrumb but neither could turn off the breadcrumb output when viewing a first level menu item. I also read in another forum about another module for breadcrumbs but the link was dead;

So i thought this modified function was okay, perhaps like you say not the best solution adding a function into template but i figure whether this function is called or another similar function called its still processing time and well, this little function works. 

cheers,

Matt

I was trying to limit the breadcrumbs output so as not to show first level menu items and after looking a little deeper into function  show_breadcrumbs()  and playing with the current parameters I didn't think this was possible?

For my example I copied & renamed the function  show_breadcrumbs()  into my templates index.php as per below and added a new parameter to the beginning of the sequence of parameters in the function.

I imagine this conditional statement could be coded better/differently as it may not be aware of conditions for advanced situations?

          if (count($bca)==1 && $noRootLevel==1)
