load plugin core file only in one page

Hi,

Well, there is no option, but it could be doable, programatically. Try adding this custom code to the functions.php in your theme/child theme directory. Before editing, please make sure to have a full site back-up just in case!

add_filter( 'asl_stop_loading', 'asl_stop_loading_condition', 10, 1 );
function asl_stop_loading_condition( $stop ) {
	if ( !DOING_AJAX ) {
		if ( get_the_ID() != 1234 ) {
			$stop = true;
		}
	}
	
	return $stop;
}

Whenever this funtion returns true, the plugin stops loading. In this example, if the current page ID is not 1234, the plugin does not load further.
You can use this to check the current page ID or whatever condition you want.

Best,

Maybe a different variation, but the previous should work as well.

add_filter('asl_stop_loading', 'asl_stop_loading_on_pages', 10, 1);
function asl_stop_loading_on_pages($return) {
	// Page IDs where the plugin should be loaded
	$pages_to_load_on = array(1, 2, 3);
	
	// -- Don't change anything below this --
	$url = home_url(add_query_arg(array()));
	$current_page = url_to_postid($url);

	if ( wp_doing_ajax() || $current_page === false ) {
		return false;
	} else {
		return !in_array($current_page, $pages_to_load_on);
	}
}

Change the $pages_to_load_on variable to the page IDs, where the plugin assets should be loaded.

Make sure to clear the site cache as well, otherwise it may have no effect whatsoever.

Best,
