How to get the parameters of another component from your Bitrix module?

Question

1C-Bitrix

Hello!
The question at first seemed simple, but for the whole day the solution was not found.
In general, I am writing a module for Bitrix, in which I need to get the value of the FILTER_NAME parameter from the arParams of the bitrix:catalog component . I have no idea
how to do this. The arParams array is available only inside this component, but it turns out that I need to somehow "see" this setting from a third-party module.
Maybe someone can suggest something? I already thought about pulling it out with a direct query from the database to the table b_component_params

Answer 1

If, for example, a variable is set in the catalog template and then used in the
<?
$GLOBALS["filter"] = $arParams["FILTER_NAME "];
?>
