Adding a date range search for CGridView the easy way

Created 3 years ago by mikewalenTips6 comments – viewed 27,351 times – ( +12 ) – version 1.1
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.

So in this case you have to write a controller action to return you a json encoded list. What if I had a generic action to do this work for me?

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:

Directory independent extensions

Created 5 years ago by GOshaTips3 comments – viewed 10,537 times – ( +16 / -1 ) – version 1.1
Many people want to use downloaded extensions in their own way. As for me most of the extensions require me to correct Yii::import() instructions inside their source code. All these extensions are directory dependent. To avoid the situation described above, I suggest to implement pseudo-anonymous aliases:
