bcn_display_json_ld is a display function for Breadcrumb NavXT that generates Schema.org BreadcrumbList compliant JSON-LD markup. It will generate a breadcrumb trail for the current page (resource, not post type). The following is the function’s prototype
bcn_display_json_ld($return = false, $reverse = false, $force = false)- $return the first parameter, it is a boolean and controls whether or not the breadcrumb trail is returned or echoed. Set to true to return the assembled breadcrumb trail string. It defaults to false if no value is passed in.
- $reverse the third parameter, it is a boolean and controls the order the breadcrumbs are arranged within the trail. Set to true to have the current item’s breadcrumb show up first in the breadcrumb trail (this is revered of the normal behavior). It defaults to false if no value is passed in.
- $force the fourth parameter, it is a boolean and controls whether or not generation of the breadcrumb trail should be forced (e.g. should the internal caching mechanism be bypassed). It defaults to false if no value is passed in.
