Removing Titles from Custom Post Type

[dwmytai]

I added a custom post-type for specific certificates on my site. Link here: dw-testing/wordpress

I've removed post titles from showing up on all the pages, but need them to also be removed for these Certificate pages.

I tried:

PHP Code:

function child_remove_certificate_titles() {
    if ( is_certificate() && ! is_certificate_template( 'certificate_blog.php' ) )
        remove_action( 'genesis_post_title', 'genesis_do_post_title' );
} 


which is similar to the function I used to remove the titles from all the Pages.

Also, I want the search results for the Certificate pages to show the full post, links included, not an excerpt (trying to reduce the number of clicks necessary).

Any advice would be appreciated! Thanks,
