Date conversion to database date

Question

I am using Kohana 3.1

Model:

    public function filters()
    {
        $filters = parent::filters();

        $filters['birthday'] = array(
            array('date', array('Y-m-d', strtotime(':value')))
        );

        return $filters;
    }

birthday input(form value):

23/05/1989

database output:

1969-12-31

What am I doing wrong?

Answer 1

public function filters()
{
    $filters = parent::filters();

    $filters['birthday'] = array(
        array(function($value) {
            return date('Y-m-d', strtotime($value));                
        })
    ); 

    return $filters;
}
