If any fields are not valid, the form will not be submitted and the user will be informed with error messages for the fields that are causing problems.To get started, we'll create an HTML page that include a form with the id "contact". It should contain an label, an input (or textarea), and a span that will contain the error message.In the example each field is checked by a different function.You could as well have each field checked by the same function. Php dynamic pages Perl/cgi scripts My SQL databases Password protected folders Advanced log file stats Spam & Virus checked mail Auto-installed scripts: Forums, Chat, Shop, Photo album, Livehelp etc.The form in HTML will look like this: tag improves usability.Clicking on the label will move the mouse cursor to the input with the id specified in the for attribute.

By validating form responses before accepting them, we can alert users to their errors before they submit the form.All credit cards are 16 digits and the 16th digit can be calculated based on the first 15 numbers.This means you can use Java Script to check for, and alert the user to, credit card typos.If the data is invalid, the input box should be red.Therefore, we'll create CSS classes to represent these possible outcomes.
