This is a reference to be used for Model rule validation and is compiled from the Yii documentation and code. The purpose is to have all the information gathered in one place instead of scattered. This reference is not an intro.
See The Definitive Guide to Yii, Declaring Validation Rules for a tutorial.
A common source of confusion among new Yii users is how the 'safe' validator works, how it works with other validators, and why it's necessary in the first place. This article means to clear up this confusion, as well as explain the notion of Massive Assignment.
How do you read and handle tabular data submission via form in Yii framework 2.0? Sometimes we want to collect user input in a batch mode. That is, the user can enter the information for multiple model instances and submit them all at once. We call this tabular input because the input fields are often presented in an HTML table.

When you're filling up a form of a CActiveRecord (using CActiveForm for example), usually you'll construct your code so that in case of validation error you'll get back the form with the error displayed back to you, typically when CActiveForm.errorSummary() is used. This is how its done by Gii.
The yii2-field-range extension enables you to easily setup ActiveField range fields with Bootstrap styling. You basically can setup two attributes joined together like a single field with combined validation error block.
