[toplisek]

I need help as I would like way to keep a single braedcrumb file if there is value without element. if there is value for element, it should be added code in braedcrumb file as following:
[PHP]$bc->elements[1]->subdirs=array("Mainproducts101.php","Mainproducts102.php");[/PHP]

Need correct code with IF script and control value of element.

I'm not sure if your question is entirely clear. Can you please restate your problem differently and maybe give an example?
