file upload - Yii form builder -

i've been working on yii-based application. , i've faced weird thing...

what i'm trying add together input(type=file) form. form created via form builder(cform class). input not going appear.

my code. controller/action:

$model=mymodel::model()->findbypk(700); $model->scenario='my-scenario'; $form=new cform('path.to.forms.my-form', $model); $this->render('view', array('form'=>$form));

view:

echo $form

form config:

return array( 'attributes' => array( 'enctype' => 'multipart/form-data', ), 'elements' => array( 'name' => array( 'type' => 'text', ), 'image' => array( 'type' => 'file', ), ), 'buttons' => array( 'save' => array( 'type' => 'submit', 'label' => 'save', ), ), );

model:

//..... public $image; // .... public function rules() { homecoming array( //... array('image', 'file', 'types'=>'png', 'on'=>'my-scenario'), ); }

with code above expected see 2 fields - text , file. text 1 appears.

if alter file validator to, say, required - works, need file validator.

i'm using yii version 1.1.13.

the intresting code above works expected before yii(1.1.9). known bug in new version? if yes - there solution? or have rollback previous version?

thanks in advance.

update:

if add together sec validator (one file , 1 required) work?

no, doesn't. believe found why. see bellow.

it seems caused line in cform..

yes, correct. yesterday, armed debugger went deeper:)

cformelement::getvisible() calls cmodel::isattributesafe() , cmodel::getsafeattributenames().

cform::getsafeattributenames() gets model validators , leaves safe ones. can see cfilevalidator not safe.

so, doesn't matter how many safe validators(required or other) have attribute assigned. cform::getsafeattributenames() removes whitelist if there @ to the lowest degree 1 unsafe(file). file validator unsafe since 1.1.12 version. why worked me in 1.1.9 :)

hence problem in cfilevalidator(or @ to the lowest degree connected it) , not in cform.

the 1 solution can see far creating own validator extended cfilevalidator marked safe , using instead of built in. can't imagine problems may cause(i believe yii developers had reason making unsafe).

i hope helpful somebody.

update 2

array('image', 'file', 'safe'=>true, 'types'=>'png', 'on'=>'my-scenario')

this validation rule(explicit safe=true) works.

if add together sec validator (one file , 1 required) work? ran myself.

it seems caused line in cform:

if($element->getvisible()) { ... }

the getvisible checks active validators current model scenario , leaves out inputs aren't used in current validator rules. i've ended commenting things out in our custom cform model our system, if allow me know if find works improve you.
