function views_handler_filter::exposed_info

Tell the renderer about our exposed form. This only needs to be overridden for particularly complex forms. And maybe not even then.

Return value

array|null: For standard exposed filters. An array with the following keys:

• operator: The $form key of the operator. Set to NULL if no operator.
• value: The $form key of the value. Set to NULL if no value.
• label: The label to use for this piece.

For grouped exposed filters. An array with the following keys:

• value: The $form key of the value. Set to NULL if no value.
• label: The label to use for this piece.
