Specifying second constructor parameter of HTML_Header_Javascript() object to TRUE forces script to be placed in
array of footer scripts. As HTML_Header renders HTML code that is valid only when placed within <HEAD /> tag,
where footer scripts, the additional action has to be performed when user wants to display footer scripts. And to
get footer scripts one has to invoke Html_Header::get_javascripts_footer() method with optional parameter, which when set to TRUE will render the <SCRIPT> code instead of just returning array of defined scripts. Then place the result somewhere in template or other view.
class Controller_Template extends Controller
{
protected $html_header = NULL;
public function before()
{
// Initialize the header
$this->html_header = new HTML_Header();
// Set the title
$this->html_header->set_title('New awesome page');
// Simple CSS attaching:
$this->html_header->add(new HTML_Header_Stylesheet(array('file' => 'stylesheet.css'));
// Example of wrapping CSS file into conditional comments:
$this->html_header->add(new HTML_Header_Stylesheet(array('file' => 'stylesheet_ie7.css', 'conditional' => 'lt IE 8'));
// Example of common JavaScript file attachment
$this->html_header->add(new HTML_Header_Javascript(array('file' => 'jquery.js')));
// Need a JavaScript somewhere else than in the <HEAD> section? Like just before closing </BODY>? set second parameter of HTML_Header_Javascript constructor to TRUE
$this->html_header->add(new HTML_Header_Javascript(array('file' => 'footer_scripts.js', TRUE)));
// Examples of <META> tag definitions:
$this->html_header->add(new HTML_Header_Meta('keywords', 'Awesome, kohana, KO3'));
$this->html_header->add(new HTML_Header_Meta('description', 'This page shows how to be awesome'));
// This one will override another one, see last parameter. Useful when in need to overwrite description or keywords depending on the page/subpage content
$this->html_header->set_meta(new HTML_Header_Meta('description', 'This META description replaces previous one'), 'description');
// Use array instead of plain parameters for non-standard, (ex. HTML5) meta tag style definition:
$this->html_header->add(new HTML_Header_Meta(array('charset' => 'utf-8')));
// ...results in: <meta charset="utf-8" />
