Magento 1 – Set Page Title After loadLayout and renderLayout

modulepage-titleseo

I need to set some tags(title, description) after i render a layout.
I know how to set the titles via layout files:

<reference name="head">
 <action method="setTitle" translate="title"><title>Your Title</title></action> 
</reference>

or via code by accessing head block element and calling setTitle('your title') method on it

$this->getLayout()->getBlock('head')->setTitle('your title');

but i need the titles to be dynamically fetched from an item from a collection.

If i go with the controller approach i will be loading the same element twice since i need to load the product to get the fields to set them as Title and Description and again in the block to show it in the product page.

Is it wise to save it with Mage::register('variable', 'value');?
Should i create the entire layout programatically and assign the data with $this->getLayout()->getBlock('your.block.name.in.the.layout')->assign('data', $data);?

When you are talking about a product, you should try to get the product before the renderLayout call, to access the head block and get the product from Mage::registry('product') or Mage::registry('current_product')

Magento – Get page title without prefix or suffix

The quick and dirty way to do it.

To cut prefix:

<?php 
$prefix = Mage::getStoreConfig('design/head/title_prefix');
$title = $this->getLayout()->getBlock('head')->getTitle();
$processedTitle = trim(substr($title, strlen($prefix)));
?>
<h1><?php echo $processedTitle;?></h1>

To cut suffix:

<?php 
$suffix = Mage::getStoreConfig('design/head/title_suffix');
$title = $this->getLayout()->getBlock('head')->getTitle();
$processedTitle = substr($title, 0, strlen($suffix) * -1);
?>
<h1><?php echo $processedTitle;?></h1>

Add Javascript File to Head for Create Block in Magento

The layout and blocks are kind of in a 'one direction' relation. I mean you can reference blocks in the layout but you cannot load layout files when creating an instance of a block. Actually you could but it's not the best idea to do so. Layouts should be called by the controllers.
When manually creating an instance of a block it has nothing to do with the layout files.
As for the second part, adding a js to the head, you have the right idea. It's done like you tried:

Mage::app()->getLayout()->getBlock('head')->addJs('js/path/here.js');

BUT... If the head block is already rendered then it has no effect. You have to make sure the js is added to the head after loadLayout() has been called in the controller action and before you call renderLayout() in the same action.
