Select page template via url parameter

    I’ve found some old ways of doing this for posts ( for example https://scratch99.com/wordpress/development/how-to-change-post-template-via-url-parameter/), but it doesn’t seem to work for pages. Not sure why. For example, I’d like to be able to do:

    mysite.com/mypage/?template=page_noheaderfooter

    I know my template works because if I select it in the page editor it produces the result I want. Here’s the code I’ve been playing with which I modified slightly from the example provided above:

    function template_query_vars($vars) {
    return array(‘template’) + $vars;
    }
    add_filter(‘query_vars’, ‘template_query_vars’);

    function url_template($template) {
    global $wp;
    if ($wp->query_vars[‘template’]==’full’) {
    return dirname( __FILE__ ) . ‘/page_noheaderfooter.php’;
    }
    else {
    return $template;
    }
    }

    add_filter(‘template_include’, ‘url_template’);`

    If it’s literally a $_GET parameter you don’t need to use any query vars. Those were if you were wanting to use an endpoint. Personally, I would use locate_template() instead of what you’re currently using. An example could look something like this:

    /**
 * Change template based on $_GET value
 *
 * @param String $template
 *
 * @return String $template
 */
function prefix_template_mods( $template ) {
	
	// Check if our GET parameter exists and holds a specific value
	if( isset( $_GET['template'] ) && 'page_noheaderfooter' == $_GET['template'] ) {
		
		// Attempt to locate our template
		$new_template = locate_template( array( 'page_noheaderfooter.php' ) );
		
		// If a template was found, switch it
		if( ! empty( $new_template ) ) {
			$template = $new_template;
		}
		
	}
	
	return $template;
	
}
add_filter( 'template_include', 'prefix_template_mods' );
