WordPress Gravity Forms plugin lets you set dynamic values for fields via shortcode ( merge tag ). You can populate a field with a date value using the merge tag {date_mdy}, {date_dmy} etc. These tags Display the current date in the MM/DD/YYYY or DD/MM/YYYY format. But there is no tag for individual parts of date like day, month and year.
Use the code snippet below. It will allow you to use 3 custom merge tags .
- {date_d} – to show the day number.
- {date_m} – to show the month number.
- {date_y} – to show the year number.
