Question

I have tried the below to display the form fields without the form start and end tag, but it seems that it doesn’t display the errors.

public function render()
{
    $output = '';

    foreach($this->getElements() as $element)
        $output .= $element->render();

    return $output;
}

Any ideas why doesn’t it display the errors ?

Answer 1

Take a look at the implementation of CFormModel::render here; there are a few interconnected methods that render taps into immediately following.

To specifically answer your question, in line 459 of the above we see

$output.=$this->getActiveFormWidget()->errorSummary($model)."\n";

That’s how Yii injects the error summary. And here you can see how a CFormInputElement renders itself; again, there is an explicit call to code that renders the error in the method renderError which is below.
