ProductCollection::get_filter_by_taxonomies_query()privateWC 1.0

Return a query to filter products by taxonomies (product categories, product tags, etc.)

For example: User could provide "Product Categories" using "Filters" ToolsPanel available in Inspector Controls. We use this function to extract its query from $tax_query.

For example, this is how the query for product categories will look like in $tax_query array: Array

(
	[taxonomy] => product_cat
	[terms] => Array
		(
			[0] => 36
		)
)

For product tags, taxonomy would be "product_tag"

Метод класса: ProductCollection{}
