How to filter by field (multiple choice)?

Question

MODX

I don't understand how to make such a request. Resources have a "multiple choice" field, where the type of fuel "Gasoline", "Diesel" is selected. There is also a multiple choice in the filter on the site (with checkboxes) Gasoline Diesel
If a person selects Gasoline and Diesel in the filter, you need to display the results of who in the admin panel is selected in the list (multiple) Gasoline, Diesel, Gasoline and Diesel
If in the admin panel there is a single list everything is simple

if(isset($_GET['fuel_type']) && !empty($_GET['fuel_type'])) {
  $where[] = 'fuel_type IN (' . implode(',', $_GET['fuel_type']) . ')';	
}

But I don’t understand how to do with the plural

Answer 1

Have you seen how the value of such a field is stored in the admin panel? Look, I think it will immediately become clear what request to write.
