Use the frm_range_end_field_synced_settings filter to choose which settings the end field of a date or time range copies from its start field. The 2 fields of a range describe a single choice, so some settings belong to the pair. You change them on the start field, and the end field takes them from there.

Requirements

• Formidable Forms Pro 7.0 or later.
• A Date field with Date Range turned on, or a Time field with Time Range turned on.

Usage

add_filter( 'frm_range_end_field_synced_settings', 'my_range_end_field_synced_settings', 10, 2 );

Parameters

• $settings (array): The field option names the end field copies. 'required' stands for the field's Required setting. By default, the list is:
  • Date and Time ranges: 'required', 'unique', 'read_only' and 'admin_only' (the field's Visibility setting).
  • Date ranges also: 'start_year' and 'end_year' (the year range).
  • Time ranges also: 'linked_date_field'.
• $field_type (string): The type of the range, 'date' or 'time'.

When the settings are copied

The end field copies each setting in the list in 2 cases:

• When the end field is created.
• Each time the form is saved. The end field then takes the values the start field was saved with.

The form builder also keeps the default settings in step while you edit, and locks them on the end field. Settings you add with this filter aren't locked or kept in step in the builder. They're copied when the form is saved.

Examples

add_filter( 'frm_range_end_field_synced_settings', 'my_sync_required_message', 10, 2 );
function my_sync_required_message( $settings, $field_type ) {
	$settings[] = 'blank';

	return $settings;
}

add_filter( 'frm_range_end_field_synced_settings', 'my_sync_unique_message', 10, 2 );
function my_sync_unique_message( $settings, $field_type ) {
	if ( 'date' === $field_type ) {
		$settings[] = 'unique_msg';
	}

	return $settings;
}

Limitations

• A copied setting replaces the end field's own value when the form is saved. Any change made on the end field is overwritten.
• Removing a default setting from the list stops it from being copied on save. The form builder still keeps it in step and locks it on the end field.
