php - Yii create a new attribute in the model doesn't work -

i need create new attribute in model , weird happening:

this code, works fine:

class person extends cactiverecord { public $test = "xxx"; public function getrandomtoken() { $temp = $this->test; homecoming $temp; }

this code, not:

class person extends cactiverecord { public $test = md5(uniqid(rand(), true)); public function getrandomtoken() { $temp = $this->test; homecoming $temp; }

why? blank page sec code, no errors.

i need utilize random token create view-page , i'm doing in way:

echo $model->getrandomtoken();

thank support!

if not want overwrite contructor can utilize this:

class person extends cactiverecord { public $test = null; public function getrandomtoken() { if ($this->test == null){ $this->test = md5(uniqid(rand(), true)); } $temp = $this->test; homecoming $temp; }

php yii cactiverecord
