Today I will show you how to handle multiple file upload step by step.

• Validate the user input (see below for details).
• Protect (escape) your application output according to context (see below for a few output types, mostly HTML and SQL).
• Test your application in debug mode.
  Set the constant YII_DEBUG to true (by default, it is defined in index.php) and put alongside error_reporting(E_ALL);. Then errors and warnings will stop the execution an...

One of the things you will find tricky to implement is the the sorting and filtering of a GridView's column that displays related model data.

Assume we want to use a single HTML form to collect input for both model A and model B, and we want to display input errors (if any) in the same error summary box. We can define the following action code:

By popular demand, today I will be revisiting my previous Yii Framework 2 Getting Started Guide and updating it with what is currently available in the Yii Framework 2 Repository. Provide here is an super simple example CRUD application that will help you get started using the framework.

Maybe it looks simple, but some time ago I need some time to find a solution of this case. I finally got it, and I want to share that I also experienced such cases. So that it can make reference.

Some times the core validation rules provided by Yii won't satisfy all your needs, so you'll need to create your very own validation rule.

Lets say we have two models and relation between them:

If we take a look at the blog demo we have 3 major parts of our view rendering. They are:

This page is created to supply short directions and general tips for managing a Yii application in NetBeans IDE.

In this article, we describe the directory structure used by yiiframework.com - the official Yii framework website. While this structure may look overly complicated for small projects or may not be optimal in some sense, we believe it is appropriate for medium or large projects in a team development environment. In fact, we have successfully used the similar structure in some other big projects.
