Hi guys,

I have a form which send the info to a php page.

I wanted a way where if $email had an "@" and a "." to run the rest of the script else echo 'No email was given'

I know its somthing like this but not sure exactly how to do it.

PHP Code:

if (isset($_GET['email'])) 

{ 

     $email = $_GET['email'];

} 

else 

{

     echo 'No email was given'

}

//Rest of the script here 

How do I put the @ and . thing in there

you can use ereg() function..

Or you can use a quicker method, strstr()

PHP Code:

<?php

if (strstr($email, "@") && strstr($email, "."))

{

echo "Your e-mail looks fine";

}

With that method, '@.' or '.@' will check as correct.

You can check for correct email syntax (xxx@xxx.xxx, xxx@xxx.xx.xx, etc...) with this (the email address is stored as $email):

PHP Code:

<?



if (ereg("^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$", $email))

echo 'Valid email address';

else

echo 'Invalid email address';



?>

Note that this will not check whether or not the address actually exists!

Yes, you are right, I'm just not to good at regexpressions.

Thanks guys it works perfactly

yep. it will work perfectly unless you never know whether the username and/or domain name exists. if you want to get REAL email address (based on DNS resolver), you may take a look at PEAR/network. Anyway, if you don't really care whether users submit fake or real email addresses, simple regex check is enough.
