Magento – Override catalog page title

catalogmagento-1.7

I want to override page title of catalog pages to include selected attributes and subcategories.

e.g. "Shoes – Adidas – Red | Brand"

What observer or model should I override to modify the page title? And how can I get current category?

Thank you very much!

You can easily change the title of the page.

Get the block head and set the title e.g.

// app/code/core/Mage/Page/Block/Html/Head.php:388
Mage::app()->getLayout()->getBlock('head')->setTitle($title);

The current category can be found here:

Mage::registry('current_category');

And the event to use? Good question. I would probably hook into core_block_abstract_to_html_before and check wether the block is Mage_Page_Block_Html_Head

public function changeTitle(Varien_Event_Observer $observer) {
    $block = $observer->getBlock();
    if($block instanceof Mage_Page_Block_Html_Head) {
        $block->setTitle(Mage::registry('current_category')->getName());
    }
}

You have to add a few more checks, e.g. you are on a category page or product page. And you have to check whether current_category exists.

Magento – Magento EE 1.13 catalog routing

(Thought I'd posted an answer similar to Alan's, but I hadn't. Sitting here in LocalStorage. But, I can tag onto his answer with an interesting solution theory.)

The CMS router adds itself to the Front Controller instance by observing the controller_front_init_routers event after the Admin and Standard routers are added. With a little config XML, it would be possible to switch this to the controller_front_init_before event, thereby adding the CMS router first, meaning its match()ing logic will run before the others.

To test this theory, drop the following into app/etc/local.xml:

<frontend>
    <events>
        <!-- fire observer for different event -->
        <controller_front_init_before>
            <observers>
                <cms>
                    <class>Mage_Cms_Controller_Router</class>
                    <method>initControllerRouters</method>
                </cms>
            </observers>
        </controller_front_init_before>
        <!-- disable the original observer -->
        <controller_front_init_routers>
            <observers>
                <cms>
                    <type>disabled</type>
                </cms>
            </observers>
        </controller_front_init_routers>
    </events>
</frontend>

See if this solves the problem.

Incidentally, the CMS router will adjust the request path in the same way as the URL rewrite model.

Magento – Category ID’s order

I hope someone comes up with a better solution, because I'm pretty sure mine if far from being perfect, sub-optimal, and VERY hacky. Anyway, when I need the most specific category related to a product, I do something like this:

$categoryIds = $product->getCategoryIds();
$collection = Mage::getModel('catalog/category')->getCollection()
        ->addAttributeToSelect('name')
        ->addAttributeToFilter('entity_id', $categoryIds)
        ->addAttributeToFilter('is_active', 1);
$collection->getSelect()->order('level DESC')->limit(1);

$name = $collection->getFirstItem()->getName();

By sorting the categories by their level, you will get the most specific one by calling getFirstItem(). Hopefully there's a better/easier way to do it which I'm not aware of, but this one works for sure.

I should note that, in case you have 2+ categories which are on the same level, you will get only one of them, specifically the first one which appears in the collection. The result is not so easy to predict, but it was usually good enough for what I needed to do.
