Validating a form heart dating soul mate
Passwords need to be stored encrypted in the database or elsewhere and any backups should also be encrypted.The form below has three input fields: username, pwd1 and pwd2. If a false value is returned then the form submission is cancelled.You might also want to spice up your forms using HTML5 Form Validation as we've done further down the page.In most browsers - those that support Java Script 1.5 (Firefox, Chrome, Safari, Opera 7 and Internet Explorer 8 and higher) - you can use more powerful regular expressions. The code presented above is fine in that it checks everything that we wanted to check, but uses a lot of code to test each requirement individually and present different error messages.The password won't appear on the screen as you type and most browsers also won't 'remember' the values entered in fields as they do with other form elements.In some cases, such as on mobile devices, displaying the password may improve usability without compromising security.
All we have changed from the previous example is to add some extra attributes to the form input fields.The simplest way to do this is to have the password entered twice, and then check that they are identical.Another method is to display what they've entered as part of a 'confirmation page'.The code presented below would then be used for letting the user change their password.
Instead of as this lets the browser (and the user) know that the contents of that field need to be secured.Some text editors (not just vi) also allow them when searching for or replacing text. This is a new technique available in modern browsers and definitely the way of the future.
