Magento: Change canonical URL for particular category only

In Magento, if you want to change canonical URL for just one category or quite a few categories, and don’t want to affect rest of the canonical URLs then do the following.

Note that this is helpful when you already have canonical URL in the page and want to REPLACE it with new url. If you don’t have canonical URL at all then you might want to ignore the first action tag in the below code.

– Go to the category page you want to change canonical URL in Magento Admin
– Click the tab “Custom Design”
– In the Custom Layout Update textbox, paste this:

1

<reference name="head">
    <action method="removeItem" block="head">
        <item>link_rel</item>
        <name>http://loca.lho.st/old-canonical-url</name>
    </action>
    <action method="addLinkRel" translate="title">
        <rel>canonical</rel>
        <href>http://loca.lho.st/new-canonical-url</href>
    </action>
</reference>

Change http://loca.lho.st/old-canonical-url and http://loca.lho.st/new-canonical-url with your desired URLs and save the category.

Basically first action tag in the code removes old canonical URL and second action tag adds the canonical URL with the new value you specify.

You may also need to clear cache.

HTH!

<?php
require_once('app/Mage.php');
umask(0);
Mage::app('admin');
set_time_limit(0);

$category = Mage::getModel('catalog/category');
$tree = $category->getTreeModel();
$tree->load();

$ids = $tree->getCollection()->getAllIds();

if ($ids)
{
     foreach ($ids as $id)
  {
     $cat = Mage::getModel('catalog/category');
     $cat->load($id);
     if($cat->getLevel()==3 && $cat->getIsActive()==1)
     {
        $category1 = Mage::getModel('catalog/category')->load($cat->getId());
        $products = Mage::getResourceModel('catalog/product_collection')
                                ->addAttributeToSelect('name')
                             ->addCategoryFilter($category1);
        echo "<b>".$cat->getName()."</b><br>";
        foreach ($products as $product) { //print_r($product->getData());exit;
                echo " &nbsp; &nbsp; &nbsp; " . $product->getName() . " - ". $product->getSku() . "<br/>";
        }
     }
  }
}
?>

Note the line which checks category getLevel()==3, you can change this line to get different subcategory levels by adjusting it.
For root category, getLevel() should be 1.
For all the main/primary categories, getLevel() should be 2.
For all the subcategories, getLevel() should be 3.
For all the subsubcategories, getLevel() should be 4.
and so on…

Above script will get you all the category and subcategories products, products assigned to each and every categories of your store.

Magento delete empty categories and sub-categories

Remove all empty categories and sub-categories in Magento. When there are empty categories, the website shows empty page in those categories in frontend. Create a file in the magento root, I will name it rmvEmptyCats.php, with following code:

1
2
3
4
5
6
7
8
9
10
11
12
13
14

require "app/Mage.php";
umask(0);
Mage::app();

$categoryCollection = Mage::getModel('catalog/category')->getCollection()
    ->addFieldToFilter('level', array('gteq' => 2)); //greater than root category id

foreach($categoryCollection as $category) {
    if ($category->getProductCount() === 0) {
        $category->delete();
    }
}

echo 'Empty Categories Deleted!';

Now you can easily run it by navigating to http://loca.lho.st/rmvEmptyCats.php and wait for the message Empty Categories Deleted!

Note that this is going to DELETE those categories with zero product count.
