   Modifying Pre-Post Links in WordPress
   we will learn how to modify the default permalink structure of your WordPress posts using the pre_post_link filter. We will write a function to customize the permalink and then add and remove this filter.

   Step 1: Add the Filter

   function wpdocs_modify_pre_post_link_defaults( $permalink, $post ) {
       // Check if the post type is 'post'
       if ( 'post' === $post->post_type ) {
           // Append '-custom' to the permalink
           $permalink = str_replace( '%postname%', '%postname%-custom', $permalink );
       }
   
       return $permalink;
   }
   
   add_filter( 'pre_post_link', 'wpdocs_modify_pre_post_link_defaults', 10, 2 );

   Step 2: Remove the Filter

   remove_filter( 'pre_post_link', 'wpdocs_modify_pre_post_link_defaults' );
