PFMaBiSmAd Posted June 22, 2012 Share Posted June 22, 2012 To test the year for the <1900 condition, you would write a simple if(){} conditional statement. Link to comment https://forums.phpfreaks.com/topic/264626-validating-date/#findComment-1356225 Share on other sites More sharing options...

Although if really old dates are not allowed there might also be a requirement not to allow future dates - but that wasn't mentioned.
