Question

I have a Yii dropdown which loads a table of cities, states, zipcodes, lat and lon. When loading the state dropdown, it takes forever. Is there a way to speed up the query to cut down on pageload time? I’ve included my view:

echo $form->dropDownList($model,'State', CHtml::listData(Zipcodes::model()->findAll(),
'State', 'State', 'State'), array('empty'=>'-- Choose State --'));

The table is 41,000 entries. Setting the $groupField in listData() didn’t seem to give any noticeable improvements.

Using CDbCriteria, I set the “GROUP BY” for the query:

$stateGroupBy = new CDbCriteria; // i got that bitch criteria. bitches love criteria!
$stateGroupBy->group = 'State'; // group by state
echo $form->dropDownList($model, 'State', CHtml::listData(Zipcodes::model()->findAll($stateGroupBy), 'State', 'State'), 
        array('ajax' => 
            array(
                  'type'=>'POST', //request type
                  'url'=>CController::createUrl('search/dynamiccities'), #we don't have to use search/, we could just say dynamiccities
                  'update'=>'#Zipcodes_City',
                  /*'data'=>'js:jQuery(this).serialize()'*/
                  ),
            'empty'=>'-- Choose State --')
        );

I flaked out in getting back to this, but this cut down on the load significantly.
