For a certain client, we had to create a custom permalink structure for a certain category of posts. We could’ve created a custom post type and that would’ve accomplished that task as well. However, that was out of the scope of the project.
Here is what we ended up with:
add_filter( 'category_link', 'custom_category_permalink', 10, 2 );
function custom_category_permalink( $link, $cat_id ) {
$slug = get_term_field( 'slug', $cat_id, 'category' );
if ( ! is_wp_error( $slug ) && 'testimonials' === $slug ) {
$link = home_url( user_trailingslashit( '/testimonials/', 'category' ) );
}
return $link;
}
add_action( 'init', 'custom_rewrite_rules' );
function custom_rewrite_rules() {
add_rewrite_rule(
'testimonials(?:/page/?([0-9]{1,})|)/?$',
'index.php?category_name=testimonials&paged=$matches[1]',
'top' // The rule position; either 'top' or 'bottom' (default).
);
add_rewrite_rule(
'testimonials/([^/]+)(?:/([0-9]+))?/?$',
'index.php?category_name=testimonials&name=$matches[1]&page=$matches[2]',
'top' // The rule position; either 'top' or 'bottom' (default).
);
}
This is just a starting point. Going through the WordPress Codex, you will find that the possibilities are endless.
