When i had created this functionality then i found some difficulties and not got much idea from wiki and forums. so, i think this will be useful for newbie users and save time of other developers when create related functionality.
I refer Collecting Tabular Input tutorial but not got clear idea for create/update.
CGridView (or CListView) together with CActiveDataProvider is a very powerful combination of the built-in tools of Yii. But how do they work together to accomplish their fantastic functions? And what are you expected to do to use them and to customize their behaviors? This article explains the very basics of them.
This wiki is a step-by-step example explaining how the controller, model and the view's CGridView work together. It explains simple things - as well as more complex things that you will anyway quickly have to know. So, even if you don't use dynamic gridviews, take a morning off and thoroughly work through this tutorial. It should save you lots of struggling.
I saw many posts that community newbie is confuse in image/photo upload with random name.
