Hi. I need to allow blank upload field in model.
Model:
public $logo;
...
public function rules()
{
return array(
array('manufacturer_name, 'required'),
...
array('logo', 'file', 'types'=>'jpg, gif, png'),
...
);
}
When I select and upload image, it works well, but I want to allow to leave empty upload field (in case that user don’t want to change logo).
Now empty field shows me error "[color=#555555][font=Arial, Helvetica, sans-serif]Logo cannot be blank.[/font][/color]". But logo is not in required rule…
