Email validation does not work ??

[spacepoet]

Hi:

 

I have been trying to get this little email validation to work:

if(empty($Email) || preg_match('~^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})$~',$Email)) {
  $error .= '- Enter your Email.';
}

....

<input type="text" name="Email" size="45" maxlength="50" value="<?php echo $Email; ?>" />

....

 

If the field is empty, it displays the error message, as it should.

 

However, it does not work when looking for a proper email, like: mysite@mysite.com

 

Can anybody tell me what is wrong?

 

I'm stumped on this ...

 

Thanks.

Look at your logic.

if they didn't give an email or it passes the regular expression test, then prompt them for their email address

I don't follow ... That's where I'm stumped on this ... can you give me some direction ...

 

Thanks.

You're checking if the email field is empty or if it is a valid email. When you give it a valid email the condition will be true.

 

Think about it. Really think about it. Then try this:

if(empty($Email) || !preg_match('~^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})$~',$Email)) {

Hi:

 

Thanks - it works great! I see you also have it check for a ".co" extension.

 

I'm not good with RegEx code - never learned much of it.

 

I guess it's time, huh?

 

I'll look at it in better detail, but thanks for the help.

OR perhaps you could use the built in email validator?

 

if($Email == '' or (!filter_var($Email, FILTER_VALIDATE_EMAIL)))

{

die('<br> You completed the Email field incorrectly, please try again');

}
