Hello @kartik,

The validation feature built into Laravel lets you check lots of things, including if a value already exists in the database. Here's an overly simplified version of what you need. In reality you'd probably want to redirect back to the view with the form and show some error messages.

// Get the value from the form
$input['email'] = Input::get('email');

// Must not already exist in the `email` column of `users` table
$rules = array('email' => 'unique:users,email');

$validator = Validator::make($input, $rules);

if ($validator->fails()) {
    echo 'That email address is already registered. You sure you don\'t have an account?';
}
else {
    // Register the new user or whatever.
}

);

Laravel has built-in human readable error messages for all its validation. You can get an array of the these messages via: $validator->messages();

Hope it helps!!

Thank You!!
