Enable Breadcrumbs

Breadcrumbs gives you a function, wpc_get_breadcrumbs(), that returns an SEO-friendly breadcrumb
trail (with schema.org markup for rich results) for the current page.

Enabling

Turn on Tools → Site Tools → Enable Breadcrumbs. The wpc_get_breadcrumbs() function only exists
while that toggle is on.

Usage

The function returns the HTML (it doesn’t print it), so echo it:

// In a theme template:
echo wpc_get_breadcrumbs();

// In a WP Coder snippet's PHP tab:
echo wpc_get_breadcrumbs();

// With custom options:
echo wpc_get_breadcrumbs( [
    'separator'  => '/',
    'taxonomy'   => 'product_cat',
    'label_home' => 'Start',
] );

On the front page it returns an empty string (no trail is shown there).

Options

Pass an array to wpc_get_breadcrumbs( $args ). Defaults:

Option	Default	Purpose
`class-ol`	`breadcrumbs`	CSS class on the wrapping `<ol>`.
`class-li`	`breadcrumb`	CSS class on each item.
`class-link`	`breadcrumb__link`	CSS class on each link.
`class-current`	`breadcrumb__current`	Extra class on the current-page item.
`class-separator`	`breadcrumb__separator`	CSS class on the separator.
`separator`	`‣`	Markup between items.
`taxonomy`	`category`	Which taxonomy supplies the term trail on single posts (e.g. `product_cat`).
`display_current`	`true`	Whether to show the current page as the last crumb.
`label_home`	`Home`	Label for the first (home) crumb.
`label_search`	`Search Results for "%s"`	Current-crumb label on search results.
`label_404`	`Page not found`	Current-crumb label on 404 pages.

⚠ To hide the current crumb, pass 'display_current' => 'false'.

⚠ No CSS is bundled — style the trail yourself using the classes above.

What the trail contains

Context	Trail
Front page	(empty)
Blog posts page	Home → current page title
Post type archive	Home → archive title
Single post/page	Home → archive → parent pages → first term + ancestors → current title
Category / Tag / taxonomy	Home → archive → term ancestors → current term
Search results	Home → “Search Results for …”
404	Home → “Page not found”
Author archive	Home → author name
Date archive	Home → year (→ month) → current

For developers

Two filters let you customize the output:

Filter	What it changes
`wpcoder_breadcrumbs_args`	The options array before the trail is built.
`wpcoder_breadcrumbs_links`	The array of link crumbs before output (to insert or remove items).

add_filter( 'wpcoder_breadcrumbs_args', function ( $args ) {
    $args['separator']  = '›';
    $args['label_home'] = 'Home page';
    return $args;
} );
