Template Include crashing browser

Question

I am creating a plugin which requires use of custom templates so using the following code to use the templates:

add_filter('template_include', 'hhavideo_set_template');
 function hhavideo_set_template( $template ){
  if(is_archive('hhavideo') && 'archive-hhavideo.php' != $template ){
   $template = include( plugin_dir_path( __FILE__ ) . 'templates/archive-hhavideo.php');
  }
  if(is_singular('hhavideo') && 'single-hhavideo.php' != $template ){
   $template = include( plugin_dir_path( __FILE__ ) . 'templates/single-hhavideo.php');
  }
  return $template;
 }

When that code is used, both templates crash my browser (Firefox), I sometimes get the error message that I have used the maximum execution time of 60 seconds.

The templates only have get_header and get_footer in them, the site runs perfectly fine on other pages.

What am I doing wrong, is there a better way to call the template files from the plugin?

Edit: Error I am now getting:

Warning: include(1) [function.include]: failed to open stream: No such file or directory in /wp-includes/template-loader.php on line 74

You have a couple mistakes in your code:

• is_archive() does not accept any parameters

is_archive() does not accept any parameters. If you want to check if this is the archive of a custom post type, use is_post_type_archive( $post_type )

• Instead of using include( plugin_dir_path( __FILE__ ) . 'my-template.php');, use dirname( __FILE__ ) . 'my-template.php';

• Single templates has its own filter, single_template, so split your function so that you have your template_include for the archive page separately

Try something like this

add_filter('template_include', function ( $template ) {

    if( is_post_type_archive( 'hhavideo' ) ){
        $template = dirname( __FILE__ ) . '/templates/archive-hhavideo.php';
    }
    return $template;

}, PHP_INT_MAX, 2 );

add_filter( 'single_template', function ($single_template) {

    if ( is_singular( 'hhavideo' ) ) {
        $single_template = dirname( __FILE__ ) . '/templates/single-hhavideo.php';
    }
    return $single_template;

}, PHP_INT_MAX, 2 );
