I am creating a plugin where i have created a custom post type smart-event and I want to serve the single posts under this category via a single page.That's why I have created a single post page named : `single-event.php` directly into plugin folder -like- `event > single-event.php`

And I am using this function to load the single page
--

    function myevent($template) {
    if ('event' == get_post_type(get_queried_object_id()) && !$template) {
        $template = dirname(__FILE__) . '/single-event.php';
    }
    return $template;
    }
    add_action( 'single_template', 'myevent'));

But the single post is being shown in theme single.php page not in the page i have created.

> Below is my CPT register code and i have flush the rewrite mode in permalink settings.

    function eventCPT(){
