Custom post type single page template

I tried adding the page-attributes support but the template option isn’t available

add_filter('single_template', 'my_single_template');
function my_single_template($single) {
	if(file_exists(get_template_directory() . '/single-' . get_the_ID() . '.php'))
		return get_template_directory() . '/single-' . get_the_ID() . '.php';
	return $single;
}

Then just create a file single-90.php,that’s ok!

That worked perfect man!!!!

I’m very thankful!

@Gyrate360 – the website in your user profile appears to be violating WordPress’s domain name/trademark policy –

I used the function above to use a custom single post, but no success.
I used a custom post type for my store so the pages won’t be mixed with regular site pages.
I have example.com/store/checkout
and I used single-842.php based on the page checkout id.
Still not displaying checkout page based on single-842.php
I am using wordpress 3.8

Have you tried it with a single.php template for your custom post type (single-store.php if store is the custom post type name).

Here is another way to get a template based on the post id:

add_filter( 'template_include', 'single_id_template', 99 );

function single_id_template( $template ) {

	$post_id = get_the_ID();

	if ( is_single() &&  $post_id ) {
		$_template = locate_template( array( 'single-' . $post_id .'.php'  ) );
		$template = ( $_template ) ? $_template : $template;
	}

	return $template;
}

Thanks, the above functions works great. I have a solution, but it was too lengthy. I added the template page option to the custom post type, but it’s ended up been on other pages.

keesiemeijer, THANKS a lot for last snippet, it saved a lot of time to me =)
