Mutationevent :: Validate.js :: exemples. All About Validation in CakePHP 1.2 – Part 2 « Another Cake Bake. In my previous article I discussed the new constructs for Model::validate. This article follows on from this and is a run down of the new validation methods and rules available. First up there are a couple of regular expressions defined, which are the same from CakePHP 1.1 and are pretty self explanatory. These are VALID_NOT_EMPTY, VALID_NUMBER, VALID_EMAIL, and VALID_YEAR (between 1000-2999). The general format of the following validation methods is var $validate = array('field' => array('rule' => 'ruleName')); Where parameters are required, such as between and cc, the format is var $validate = array('field' => array('rule' => array('ruleName', 'param1', 'param2')); alphaNumeric Allows only digits and a-z or A-Z. between Checks that a strings length is between a min and max value. blank Checks if a field is empty and treats whitespace characters as empty. cc Credit Card Number validation, includes luhn check and Card Type to number format.

"But aren't there already a ton of validation plugins out there? " Not convinced? A single line of jQuery to select the form and apply the validation plugin, plus a few annotations on each element to specify the validation rules. Of course that isn't the only way to specify rules. After trying to submit an invalid form, the first invalid element is focused, allowing the user to correct the field. You're probably looking for If not, read on. Notable features of the demo: Examples. Here you will see LiveValidation in action, and the code that makes it all happen, to serve as examples of its capabilities and as tutorials to get you started. IMPORTANT - As you probably already know, relying on client-side validation alone is a very bad idea. Always perform appropriate server-side validation as well.
The purpose of this library, and javascript validation in general, is not to replace server-side validation, but make the act of filling in a form less daunting for a user, and to save them time. Contents Homepage example Top First up, just in case you were wondering, the homepage example consists of 2 validations - Presence to make sure it is filled in, and Format to check that the value entered contains ‘hello’ in any case.
