Adding a date range search for CGridView the easy way

Created 2 years ago by mikewalenTips5 comments – viewed 21,585 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.

Directory independent extensions

Created 4 years ago by GOshaTips3 comments – viewed 9,644 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:

A simple action for CJuiAutoComplete

Created 4 years ago by tydeas_drTips9 comments – viewed 32,322 times – ( +16 / -1 ) – version 1.1
More or less I use auto-complete field for a form. CJuiAutoComplete is a yii widget for this purposes. The common use case is to make an ajax request and retrieve a list from the database. 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?
