How can I set a date to NULL in Yii?

Question

I have a date column that usually takes values as dd.MM.yyyy. Its validation rule in the model\'s rules() is this:

array(\'start, e         


        

Answer 1

The trivial fix for this is not to set the value at all during creation:

if (!empty($csv_data)) {
  $user->start = $csv_data;
}

This way, the date will not be set and thus appear as empty, which also passes validation.
