Pattern Constraint for email in backoffice

[Former Member]

Hi ,

I have an email field in one of my custom model.

I want to use the below regex pattern to be used for validating in backoffice. \\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,20}\\b

Tried to use PatternConstraint,but it was always throwing invalid email even i enter valid email.

Could some one please throw light on the same?

Your RegEx, \\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,20}\\b seems to invalid for email. It does not even pass an email address like a@b.com. You can check a Java RegEx using an online tool like https://www.freeformatter.com/java-regex-tester.html .

You can try a RegEx like the one given below from the link I have mentioned above:

 ^[-a-z0-9~!$%^&*_=+}{\'?]+(\.[-a-z0-9~!$%^&*_=+}{\'?]+)*@([a-z0-9_][-a-z0-9_]*(\.[-a-z0-9_]+)*\.(aero|arpa|biz|com|coop|edu|gov|info|int|mil|museum|name|net|org|pro|travel|mobi|[a-z][a-z])|([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}))(:[0-9]{1,5})?$
