Breadcrumb ...

Recommended Posts

I've only been playing with PHP for about 4 months so im slowly getting there.

On my test website i've made a breadcrumb trail ... for example it might look something like this

Home >> Customer Information >> Help >> FAQs.

Is it poss to do an if statement on the trail?

So if the breadcrumb trail says Help then do a song and dance  ;D

Cheers
