Question

I try update num_of_gifts without select use yii active record and CDbCriteria
this is my code:

$attributes = array('num_of_gifts' => 'num_of_gifts'+1);
$condition = 'bla bla';
$params = array(bla bla);
Gifts::model()->updateAll($attributes, $condition, $params);

all I get that “1” at the num_of_gifts cell,
is it possible increase 1 to num_of_gifts? or I need select the amount of num_of_gifts and after it use update?

Answer 1

If you are just updating counters you could use Yii’s updateCounters method.

Example for updating all:

Gifts::model()->updateCounters(array('num_of_gifts'=>1));

That method takes a condition to update a specific record, but if you don’t include a condition it will update all records.

[edit]

If you want to update selected records based on a condition, the format is this:

Gifts::model()->updateCounters(
        array('num_of_gifts'=>1),
        array('condition' => "param = :param"),
        array(':param' => 'paramvalue'),
    );
