DESCRIPTION

This feature allows you to make groups of controls work together. If any one of the named controls have a value when checked, then all of them must or the form will be invalid and an error will be displayed.

ATTRIBUTES

groups

This is how the control groups are configured. Each key is used to name a control group and the values are arrays of controls that are grouped together. This way more than one none-or-all requirement can be set on a given form.

At this time, the control group names are ignored, but might be used in the future for linking additional settings together.

METHODS

check

This runs the checks to make sure that for each group of controls, either all have a value or none do.
