Yii : CGridView – Create Custom Column

I have a field which contains one character to represent project status (eg: F=Finished, S=Start, P=Pending, etc)

By default, CGridView will display one character value, but we want CGridView to display its description taken from other table, this is what I did:

First, create a component, let’s name it MyComponent. You can do it by create MyComponent.php and save it in component folder, I write something like this:

class MyComponent extends CApplicationComponent 
 public function getProjectStatus($statusCode)

 $rs = Yii::app()->db->createCommand($sql)->queryAll();

 $data = array();

 foreach($rs as $item){

 $statusCode = $item['STATUS_CODE'];
 $description = $item['DESCRIPTION'];

 $data[$statusCode] = $description;
 return $data[$statusCode]; 

This way, you can call the function like this

Then, replace the field name in your views (admin.php) with something like this

array('header' => 'Project Status', 'value' => 'Yii::app()->mycomponent->getProjectStatus($data->PROJECT_STATUS)'),

Some people suggest the function should be static

Yii version: 1.1.10

Adminer – Set Number of Rows to Display

I’ve ever wrote how to set this on PhpMyAdmin, now I want to do it on Adminer. I want Adminer to show 200 records when I select a table. I’ve try it using Adminer v4.1.0 and v4.2.0 both for MySQL english only.

I just search the string “selectLimitProcess(){” with no quote off course and then replace its default number from 50 to 200, you can use any number you want.
