Question

I try it via my Zend_form:

$output .= $this->_view->render('admin/form.phtml'
                , array('id' => $this->getName()
                    , 'action' => $this->getAction()
                    , 'method' => $this->getMethod()
                    , 'enctype' => $this->getEnctype()
                    , 'data' => array('code' => $code
                                    , 'name' => $name
                                    , 'description' => $description)));

but when i <?php echo $this->enctype; ?> in admin/form.phtml i got nothing.

admin/form.phtml is rendered correctly

Choosing render just displays the output, Zend does not pass your data to the view. But Using view partials, you could achieve that.

From the documentation,

The Partial view helper is used to render a specified template within
its own variable scope. The primary use is for reusable template
fragments with which you do not need to worry about variable name
clashes. Additionally, they allow you to specify partial view scripts
from specific modules.
