Sam:
Based on your code the value for $this->data['Outlet']['photo'] is an array
instead of a string field indicated by $validate and "$this->set('photo',
$filename)". This suggests that the type for $this->data['Outlet'][
'photo'] is transitioning from an array to a string. You would have to
make sure that $this->data['Outlet']['photo'] contains a string value when
validate() is executed. Is it possible that your afterValidate function is
supposed to be beforeValidate?
