CalcBuilder Tutorial

The Date field shows a calendar picker and validates the entry against your date format.

Key settings

• The display format follows Date format on the calculator Preferences tab (e.g. d/m/Y).
• Use a mask (Date 00/00/0000) if you want a plain typed date.

In code

$variable holds the string the visitor picked. Convert it with DateTime::createFromFormat('d/m/Y', $variable) to do date maths (age, days between, due date).

Part of the Form Fields reference. All types are demonstrated together in the Field Types Showcase.
