Returns a select tag with options for each of the days 1 through 31 with the current day selected. The date can also be substituted for a hour number. Override the field name using the :field_name option, ‘day’ by default.

Examples

my_date = Time.today + 2.days

# Generates a select field for days that defaults to the day for the date in my_date
select_day(my_time)

# Generates a select field for days that defaults to the number given
select_day(5)

# Generates a select field for days that defaults to the day for the date in my_date
# that is named 'due' rather than 'day'
select_day(my_time, :field_name => 'due')
