is there a way to get all queued scripts/styles into a template without `get_header()`?

Question

in my main plugin page i check if a certain page is visited if so, i load a certain template. in the following way:

add_filter( 'template_include', array($this, 'includeTemplate'), 99 );
public function includeTemplate($template){ 
    global $wp_query;
    if(is_page() && $wp_query->query['pagename'] == 'my_page_name'){
       include(plugin_dir_path( __FILE__ ).'templates/my_page_name.php');
       die;
    }
    return $template;
}

my question is how can i load all the queue scripts and styles to this template without using the_header()

I've tried :

global $wp_scripts;
foreach( $wp_scripts->queue as $handle ) :
    echo $handle . ' | ';
endforeach;

The above echoed admin-bar

Thanks.

Answer 1

the_header() does not even seem to be native WP function?

Technically getting header isn't what really causes styles and scripts to load, it's wp_head() call that should be made there (and wp_footer() call in footer). So they are likely what you should be using.

If you do need something lower level you might want to look at:

• wp_print_styles()
• wp_print_head_scripts()
• wp_print_footer_scripts()

Answer 2

Untested, but you should be able to run the wp_enqueue_scripts filter yourself.

do_action('wp_enqueue_scripts');

That should give you the best chance of loading scripts and styles without also loading other things that might be hooked into (rightly or wrongly) [wp_head'][2], [wp_footer][3], or thewp_print_styles` hook, which seems to be subject to abuse.

You may also want

do_action('wp_print_head_scripts');

and

do_action('wp_print_footer_scripts');
