Question

I’ll first describe my initial problem – I have a few site global variables (such as whether I’m online/offline, the price of the item etc).. I was wondering how best to store/retrieve these as they are needed on most pages.

In the end after some guidance I’ve opted to store them in a DB and create a component class (in Yii) to access them from where ever: e.g. echo Yii::app()->variables->price

I’m new to Yii, and I’ve been searching around but cannot find out how to properly interface a DB (AR Style) connection with a component.. So far I’ve created a Model class and the DB with columns 'id', 'name', 'value'

Just to get the hang of it I’m writing a method: getTestValue() in my component class, but I just don’t know how to go about retrieving the row with name test using Yii’s ActiveRecord. Could someone point me in the right direction please? 🙂

Many thanks!

This should work:

function getTestValue(){
  $myvalobj = YourModelClass::model()->findByAttributes(array('name'=>'test'));
  if($myvalobj!==null)
     return $myvalobj->value;
  return null;
}
