robert_gsfame Posted July 23, 2009 Share Posted July 23, 2009 Does anyone have the solution for this. i actually want to create a login form but when username textbox left blank, alert popup started to appear stated "Username cannot left blank", else it comes to page2.php and POST the username. Page2: $username = $_POST['username']; echo $username; Please help me for page1 (*Don't relate this to sql database*) Quote Link to comment Share on other sites More sharing options...
GingerRobot Posted July 23, 2009 Share Posted July 23, 2009 You can use Javascript to test the user's data prior to submission, but this should be used only to make things more user-friendly; you must check all data server-side too. If you google for javascript alert boxes and javascript form checking then you'll find what you need, whilst you can use the strlen fuction to test the length of the username in your PHP script (after trimming any whitespace i'd imagine).
