Custom Post Type Rewrite Rule

Question

My theme uses the following code:

'rewrite' => array('slug' => $this->safe_name . '-detail'),

which produces this slug:

http://www.example.com/estate-detail/4-bedroom-property-for-sale/

I need to get rid of the 'estate-detail' part so I changed the rule to just:

'rewrite' => array('slug' => ' '),

This produces the slug as:

http://www.example.com//4-bedroom-property-for-sale/

How do I get rid of the double forward slash?

Answer 1

add_filter( 'post_type_link', 'filterslash_post_type_link', 11, 2);

function filterslash_post_type_link( $post_link, $post ){
    $post_link = home_url("/$post->post_name/");
    return $post_link;
}
