set dynamic post title

Hello,

Thank you for contacting Rank Math about setting a dynamic post title using the current year variable.

The default post title does not support Rank Math variables. To enable support for Rank Math variables you will need to add the following code snippet to your theme’s functions.php file:

function rm_title_replace_vars( $title ) {
    return RankMath\Helper::replace_vars( $title );
}
add_filter( 'the_title', 'rm_title_replace_vars', 10, 2 );

add_filter( 'rank_math/frontend/title', function( $title ) {
    $title = get_the_title();
    return $title;
});

I hope that answers you. Let us know if you have questions. We are here to help.
