AyKay47 Posted January 25, 2012 Share Posted January 25, 2012 holy big text batman.. you are receiving these "notices" (they aren't errors) because you are attempting to call on $_POST values that do not exist upon page load. if(isset($_POST['username']) && isset($_POST['password'])) { $username = $_POST['username']; $password = $_POST['password']; } Quote Link to comment Share on other sites More sharing options...
Drongo_III Posted January 25, 2012 Share Posted January 25, 2012 check if it's set first? i.e. if(isset($_POST['password'], $_POST['username'])){ $username = $_POST['username']; $password = $_POST['password']; } else { Do whatever........ } Quote Link to comment Share on other sites More sharing options...

Drongo_III Posted June 6, 2012 Share Posted June 6, 2012 Hello Your problem looks to be on your form. You have named the field "passsword" - note the incorrect spelling of password (you have added three S's). The php script is then looking for 'password' - with the correct spelling. This is why you are getting undefined index. Your form is posting "passsword" but your php script is looking for "password" in the post array. Hope that fixes it!
