Hi all,

I have a login system for the site. My problem is I am very new to php and battling to understand this. What I want to do is only accept logins from people that have emails from a certain domain. Here is the code I have at the moment. I would think this kind of validation or check would accur here somewhere?

`<?php
// Connects to your Database

mysql_connect("localhost", "dbuser", "dbpassword") or die(mysql_error());

mysql_select_db("dbname") or die(mysql_error());

//This code runs if the form has been submitted

if (isset($_POST['submit'])) {

//This makes sure they did not leave any fields blank

if (!$_POST['username'] | !$_POST['pass'] | !$_POST['pass2'] ) {

    die('You did not complete all of the required fields');

}

// checks if the username is in use

if (!get_magic_quotes_gpc()) {

    $_POST['username'] = addslashes($_POST['username']);

}

$usercheck = $_POST['username'];

$check = mysql_query("SELECT username FROM users WHERE username = '$usercheck'")

or die(mysql_error());

$check2 = mysql_num_rows($check);

//if the name exists it gives an error

if ($check2 != 0) {

    die('Sorry, the username '.$_POST['username'].' is already in use.');

            }

//this makes sure both passwords entered match

if ($_POST['pass'] != $_POST['pass2']) {

    die('Your passwords did not match. ');

}



// here we encrypt the password and add slashes if needed

$_POST['pass'] = md5($_POST['pass']);

if (!get_magic_quotes_gpc()) {

    $_POST['pass'] = addslashes($_POST['pass']);

    $_POST['username'] = addslashes($_POST['username']);

        }

// now we insert it into the database

$insert = "INSERT INTO users (username, password)

        VALUES ('".$_POST['username']."', '".$_POST['pass']."')";

$add_member = mysql_query($insert);

?>

<h1>Registered</h1>

<p>Thank you, you have registered - you may now login</a>.</p>

<?php
}

else
{
?>

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">

<table border="0">

<tr><td>Username:</td><td>

<input type="text" name="username" maxlength="60">

</td></tr>

<tr><td>Password:</td><td>

<input type="password" name="pass" maxlength="10">

</td></tr>

<tr><td>Confirm Password:</td><td>

<input type="password" name="pass2" maxlength="10">

</td></tr>

<tr><th colspan=2><input type="submit" name="submit"
value="Register"></th></tr> </table>

</form>

<?php

}
?> `

<?php

$email = "troll@google.com";

$domain = strstr($email, "@");

if($domain == "@google.com")
{
    echo "registration process will continue...";
}
else
{
    echo "registration process will stop...";
}
