Enhancing email address validation

(0) ShareShare
ReportReport
Posted on by Ric835 31

Hi,

I'm using the built-in functionality with Power Apps, to validate if an email address is in the correct format:

IsMatch(dcvalEmailTMP.Text, Match.Email)

 

For the most part this does its job, however, it doesn't prevent users putting spaces or 2 x periods in an email address.

e.g. the following bad email addresses are still getting through:

joe.bloggs@outlook..com or joe.bloggs@ outlook. com

 

Could anyone suggest a way of enhancing the validation, to disallow these bad addresses?

 

Many thanks

    Almost. The video talks about pre-defined patterns which is what I was already using.

    However, he did have another video which mentioned using a regex. 

    I've now found a good regex to cover it from http://www.regexlib.com This seems to work:

     

    ^[a-zA-Z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-zA-Z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-zA-Z0-9](?:[a-zA-Z0-9-]*[a-zA-Z0-9])?\.)+(?:[a-zA-Z]{2}|aero|asia|biz|cat|com|coop|edu|gov|info|int|jobs|mil|mobi|museum|name|net|org|pro|tel|travel)$

     

    Thanks for the hint.
