Top Tip: XHTML with Zend Form Elements

When you render a Zend_Form, the elements will render to HTML compliance rather than XHTML compliance, even if you have doctype('XHTML1_STRICT');?> at the top of your layout script. Practically, this means that all the input elements do not end in “/>“.

To resolve this, you need to call the doctype() view helper prior to rendering your form.

Within my projects, I do this within a front controller plug-in called ViewSetup that looks a little like this:


class App_Controller_Plugin_ViewSetup extends Zend_Controller_Plugin_Abstract
{
public function dispatchLoopStartup(Zend_Controller_Request_Abstract $request)
{
// setup the layout
Zend_Layout::startMvc();

$viewRenderer = Zend_Controller_Action_HelperBroker::getStaticHelper('viewRenderer');
$viewRenderer->init();

$view = $viewRenderer->view;
$view->doctype('XHTML1_TRANSITIONAL');

$view->headMeta()->appendHttpEquiv('Content-Type', 'text/html;charset=utf-8');
}
}

Obviously, this class lives in the file library/App/Controller/Plugin/ViewSetup.php.

As you can see, I also set up the meta tag for the content-type to UTF-8 ready for rendering later.

  1. Very helpful indeed! Thanks for sharing. By the way, it appears that you have a mismatched single quote type in appendName().

    I think this ′was meant to be this '

  2. Rob,
    I may be wrong(wouldn't be the first time) but for 'Content-Type' shouldn't you be using $view->appendHttpEquiv('Content-Type', 'text/html;charset=utf-8')?
