I www.jamesbarnsley.com was tasked to find a way to do recursive deletion in Yii. As I asked other developers and looked around the internet the usual answers all came up, use a plugin or use cascade delete at the DB level, but I did not want to do either of these.
I (www.jamesbarnsley.com) found that when using the Yii Bootstrap tabs component you will sometimes want to direct the user to a specific tab and not necessarily the first tab. Yii Bootstrap already provides the "active" variable so you can define whether the tab is the active tab or not in PHP. I generally find though that a PHP solution to this problem is rather cumbersome as every tab component will need the PHP code inserted or you will have to extend the tab component somehow to do it.
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.
It's well known that there are Lazy Loading approach and Eager Loading approach in the relational query. But it's important to note that you should distinguish 2 different modes in the Eager Loading in Yii 1.1.x.
