How to change link on breadcrumbs

Hello,

Thank you for contacting the support.

You can modify and use this filter to modify the link of the second element of the breadcrumbs:

/**
 * Allow changing or removing the Breadcrumb items
 *
 * @param array       $crumbs The crumbs array.
 * @param Breadcrumbs $this   Current breadcrumb object.
 */
add_filter( 'rank_math/frontend/breadcrumb/items', function( $crumbs, $class ) {
    $crumbs[1][1] = 'https://www.google.com/'; // Add the desired URL
    return $crumbs;
}, 10, 2);

You can replace https://www.google.com/ in the above code with the desired URL.

Here’s a guide that you can follow to add the filter to the website:

Hope this helps.

Thank you.

Hello,

Please share a few current URLs and the new URLs so that we can see if there’s a pattern.

Looking forward to hearing back from you.

Thank you.

Hello,

You will need to modify the filter I shared previously and add conditions to it as the future URLs are following a different pattern.

For the current URLs, you can modify and try using the below filter:

add_filter( 'rank_math/frontend/breadcrumb/items', function( $crumbs, $class ) {
	$url = explode('/', $crumbs[1][1]);
	if(end($url) === ''){
		array_pop($url);
	}
	$url[count($url)-1] .= '-guide';
	$crumbs[1][1] = implode('/', $url);
    return $crumbs;
}, 10, 2);

Hope this helps.

Thank you.
