[SOLVED] Help with validating form email addresses

[Sportbob]

Hello,  I would like to limit a form email field to only send to two domains. The below code works great for one domain (domain1), but what if I also want to allow users to send to (domain2) as well? Thanks for looking!

 

if(empty($var)) {

//do nothing

} else if (!eregi("^[A-Z0-9._%-]+@[A-Z0-9._%-]+domain1.edu", $var)) {

  die ("<p>Error - please go back and enter a valid domain1 email address. Form does not allow EPHI sent outside of domain1.</p>");

}

I believe you can just put a | between the two domains:

(domain1.edu | domain2.edu)

 

That should tell it to accept either domain1 or domain2.

 

You can test regular expressions here: http://regexlib.com/RETester.aspx

Yeah, I would agree with Nightslyr, using a complex regular expression wouldn't be necessary for a definite amount of domains allowed. You should just use a wild card before the domain, or check to see if the domain even exists in the string.

Thank you for the reply's.  (domain1.edu | domain2.edu) returned the die error, as did [domain1.edu | domain2.edu] or [domain1 | domain2].edu.  I will continue looking into alternative solutions.  Thanks again.

It should be something like

 

if((!strpos($email, 'domain1.edu')) || (!strpos($email, 'domain2.edu'))) {
  die('Please enter a valid e-mail address.');
}
else {
  // do something else...
}

I notice you're using ereg where I normally use preg, so perhaps the rules are different.

 

But you have domain.edu in your regexp.  That dot does not match a dot, it matches anything.  What you want is:

domain[.]edu or domain\.edu

 

Also, if you want multiple domains, try changing +domain1.edu to:

+(domain1)|(domain2)[.]edu

Thank you all very much for your replies.  I was able to resolve the issue with roopurt18's suggestion!  Thank you!  Final version below.

 

if(empty($var)) {

//do nothing

} else if (!eregi("^[A-Z0-9._%-]+@[A-Z0-9._%-]+(domain1)|(domain2)[.]edu", $var)) {

  die ("<p>Error - please go back and enter a valid email address. Form does not allow EPHI sent outside of domain1 or domain2</p>");

}
