ZF2 provides HeadScript and InlineScript Helpers to inject <script> elements in the template typically located inside the <head> tag, or at the very bottom of the closing </body> tag. To inject Title, Meta Keywords, Meta Description, headScript, and inlineScript in the view:
<html>
<head>
<?php echo $this->headTitle(); ?>
<!-- Display Meta Keywords and Description along with Viewport -->
<?php echo $this->headMeta()->appendName('viewport',
'width=device-width, initial-scale=1.0') ?>
<meta charset="utf-8">
<?php echo $this->headScript(); ?>
</head>
<body>
...
<?php echo $this->inlineScript(); ?>
</body>
</html>
And, you'll assign script tag in the Controller like this:
public function indexAction()
{
$renderer = $this->getServiceLocator()->get(
'Zend\View\Renderer\PhpRenderer');
$renderer->headTitle('Head Title');
$renderer->headMeta()->appendName('keywords', 'Meta Keywords');
$renderer->headMeta()->appendName('description', 'Meta Description');
$env = getenv("APPLICATION_ENV");
if ($env == "production") {
// Only add the script in the "production" environment.
$script = $this->getServiceLocator()->get('viewhelpermanager')
->get('inlineScript');
// No need to add beginning or ending <script> tags, as they
// will be automatically inserted by the appendScript method.
$script->appendScript(
'$(document).ready(function() { alert("Hello"); });',
'text/javascript',
array('noescape' => true)); // Disable CDATA comments
}
return new ViewModel();
}
