function date_parts_element

Creates form elements for one or more date parts.

Get the order of date elements from the provided format. If the format order omits any date parts in the granularity, alter the granularity array to match the format, then flip the $order array to get the position for each element. Then iterate through the elements and create a sub-form for each part.

Parameters

array $element: The date element.

object $date: The date object.

string $format: A date format string.

Return value

array: The form array for the submitted date parts.
