I saw many posts that community newbie is confuse in image/photo upload with random name.

CFormatter is one of Yii's core components and used to format values displayed in widgets like CGridView or CDetailView. All classic formats like numbers, text, urls or datetime are supported but you may have to use a formatting rule that isn't built in. Let's say we want to display arrays of strings (like tags associated with a product model). When using CDetailView we would usually make use of PHPs implode function to create a simple string value of all values in the $product->tags array.
After a lot of research, everything I found on adding date range searching to a CGridView advanced search form seemed to involve adding two new public variables (e.g. $date_from, $date_to), 'safe' rules for the new variables, and a rather chunky if/elseif/else check in the search() method. This probably isn't a hassle for most, but because many of the tables in my database contain two or three and sometimes four date columns (e.g. date_created, date_modified, date_deleted etc.), it meant I was having to add up to eight public variables, the corresponding safe rules, and modifying the search() criteria for each date attribute. So, I set about creating a better way and I thought I'd share my work with the community.
When using CListView to display multiple views next to each other, we can use the $index variable inside the viewFile to achieve this. As far as i know there is no extension or out-of-the-box functionality for this, so we need to apply a little hack:
