If the validation passes, our controller will continue executing normally.

Sometimes you may wish to stop running validation rules on an attribute after the first validation failure.

Validating web forms is a critical skill for any web developer, ensuring that the data that's submitted is complete, accurate, and nonmalicious before it's sent off to the server.

Join author Ray Villalobos in this course as he shows how to validate input from site visitors with HTML5, Java Script, and j Query and then process the data with PHP.

In addition, all of the validation errors will automatically be flashed to the session.

With more and more personal information being stored on the Web—credit card data, social security numbers, maiden names, favorite pets—today's PHP developer cannot afford to be ignorant when it comes to security.

Sadly, most beginning programmers fail to understand the truth about security: there is no such thing as "secure" or "insecure." The wise programmer knows that the real question is a site is.

Once any piece of data is stored in a database, in a text file, or on a Post-it note in your office, its security is compromised.

``The run()`` method only returns TRUE if it has successfully applied your rules without any of them failing. This method initializes the validation class and loads the form helper and URL helper used by your view files. Based on whether the validation was successful it either presents the form or the success page.

Code Igniter lets you set as many validation rules as you need for a given field, cascading them in order, and it even lets you prep and pre-process the field data at the same time.
