I could use sample code for enabling EPR with CPTs

FWIW – future strugglers, it’s butt-simple to edit line 93 of the plug-in to something like this:

$post_types = apply_filters( ‘epr_post_types’, array( ‘post’, ‘page’, ‘report’ ) );

It works, just replace ‘report’ above with your CPT name.

It would be nice to do this the proper way, but for now, it’s working.

Or, to make it work with all post types, change line 93 to:

$post_types = array_values( get_post_types( array( ‘public’ => true, ‘_builtin’ => false ), ‘names’ ) );

Although I’m not sure that wouldn’t bloat the bejeezus out of your database.

This seems to work for me

add_filter( 'epr_post_types', 'my_function' );
function my_function( $content_types ){
	$content_types = array('my_content_type');
	return $content_types;
}

That works, thank you!
