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.
Sometimes we get lost trying to search by a HAS_MANY relation using CActiveRecord or CActiveDataProvider in Yii 1.1. This article is a series of drills that try to describe the practical techniques of searching by a HAS_MANY relation.
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.
In this article I'll try to explain how to use standard quick search fields in CGridView with customized columns.For example:
We have a record in a database with field switch having 0 or 1 values.
After that we want a user to see on or off instead 1 or 0.
So we do the usual thing:
