Custom Fields – Format Checking

Just came across this when using the specific format “Date” within custom field creation:

The JS regex that validates the format is this:

(/^[0-9]{2}/[0-9]{2}/[0-9]{4}$/)

This doesn’t check for a valid date according to the dd/mm/yyyy format stated, rather it checks for any 2 digits separated by forward slashes (with any 4 digits on the end).

In order to have the format validated for a real date I’ve updated my regex to:

(/^(0[1-9]|1[1-2])/([0-2][1-9]|3[0-1])/(19|20)[0-9]{2}$/)

(I’ve changed mine to be mm/dd/yyyy format, with the year having to be within the 20th or 21st century)

Not perfect, but at least it guarantees I get a date in mm/dd/yyyy format.
