Validating Email Address

**Basher** · 31-08-2003, 04:23 PM

ok, I have developed a PHP script which sends a user there password, kinda a forgot password type thing. Just one thing i really cant work out. I need to validate the email address to ensure it is something@mydomain.com rather than just anyold email address, ie. it must contain mydomain.com at the end of it.

so essentially all i need to do is grab the text from the email address field, trim the contents before that '@' and store this into a variable.

then an if loop, if the variable = 'mydomain.com' then execute the script, else diaply an error message

How would I go about doing this?

Thanks

PHP Code:


<?

//Email validation for a domain - written by Adrian Gurney

// You need to pass a variable called "email" to the script, which will then check that variable



// CONFIGURATION

$domainname = "mydomain.com";

$findstring = "@";



//END CONFIGURATION



$result = strchr($email,$findstring);

$result = substr($result, 1);



If ($result == $domainname) {



?>



<html>

<head>

<title>Agents email validation</title>

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

</head>



<body>

Put your script or file contents here - email is correct

</body>

</html>



<?

}

else

{

?>

<html>

<head>

<title>Agents email validation</title>

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

</head>



<body>

Put error message here - email isnt valid

</body>

<?

}

?>

Im going to start charging for this

You need to pass the variable to the scrip with the name "email" - how you do this is upto you. I suggest you use POST.
