Change meta tags in zend framework layout

Steps to change meta tags in zend framework layout

It would recommend setting a view variable for the keywords. For example, in your bootstrap.php you could define default keywords as follows:

<?php

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap {

    protected function _initDoctype() {

        $this->bootstrap('view');

        $view = $this->getResource('view');

        $view->doctype('XHTML1_STRICT');

        $viewRenderer = new Zend_Controller_Action_Helper_ViewRenderer();

        $viewRenderer->setView($view);

        $view->headTitle('Techinfo Tricks Solutions')->setSeparator(' :: ');

        $view->keywords = 'Techinfo Tricks Web Solutions';

    }

In layout.phtml we would have then:

<?php echo $this->headMeta()->appendName('keywords', $this->keywords); ?>

Finally, in your views (or actions) you could change the Meta keywords simply by changing the keywords view variable:

// in an action

$this->view->keywords = 'new kewords';

//or in a view

<?php $this->keywords = 'new kewords'; ?>

For example some thing like this

public function aboutusAction()

{

       $this->view->keywords = 'About US';

}
