Views Breadcrumbs using Arguments
For most of my clients, I need to create Breadcrumbs. Seemingly easily, breadbrumbs is an area that is a bit more involved than most features in Drupal. There's a great module out there called custom_breadcrumbs. The module works great for the display of breadcrumbs on all node pages, but doesn't (yet) work with views.
After doing some research about a solution for view pages, here's my favorite pick: Views Arguments.
For a simple overview page (that uses views), add a "Global: Null" Argument. Within that argument, select "Provide default argument" and select "PHP Code". In here, you can use the drupal_set_breadcrumb function. That function accepts an array of link titles and paths. Here's an example:
$breadcrumb .= l('Is The Box Butler For Me?', 'use-cases');
To make this work, it's important to select "Display All Values" for "Action to take if argument does not validate", otherwise the view gets messed up.
To be on the safe side, I've attached a screenshot of the arguments code for this (live) example: http://theboxbutler.com/use-cases.
