Magento – Add a custom text field to categories in Magento 2

categorymagento2seo

I want to add a new text area to my categories in Magento2, similar to this, but its for Magento 1: adding custom drop down field to category

Basically there should be a field for each category where my customer can put in some category-based SEO content. I want to echo it later on the sidebar.

How could I achieve this? Bonus points if I can achieve this with pure XML.

You need to create a module that has Setup/InstallData.php with content similar to

public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        $installer = $setup;
        $installer->startSetup();

        $categorySetup = $this->categorySetupFactory->create(['setup' => $setup]);
        $entityTypeId = $categorySetup->getEntityTypeId(\Magento\Catalog\Model\Category::ENTITY);
        $attributeSetId = $categorySetup->getDefaultAttributeSetId($entityTypeId);
        $categorySetup->removeAttribute(\Magento\Catalog\Model\Category::ENTITY, 'bottom_description');
        $categorySetup->addAttribute(
            \Magento\Catalog\Model\Category::ENTITY, 'bottom_description', [
                'type' => 'text',
                'label' => 'Bottom description',
                'input' => 'textarea',
                'required' => false,
                'sort_order' => 101,
                'visible' => true,
                'wysiwyg_enabled' => 1,
                'visible_on_front' => 1,
                'is_html_allowed_on_front' => 1,
                'user_defined' => true,
                'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_STORE,
                'group' => 'General Information',
            ]
        );
        $idg = $categorySetup->getAttributeGroupId($entityTypeId, $attributeSetId, 'General Information');
        $categorySetup->addAttributeToGroup(
            $entityTypeId,
            $attributeSetId,
            $idg,
            'bottom_description',
            46
        );

        //$installer->updateAttribute($entityTypeId, 'bottom_description', 'is_wysiwyg_enabled', 1);
        //$installer->updateAttribute($entityTypeId, 'bottom_description', 'is_html_allowed_on_front', 1);

        $installer->endSetup();
    }

You need to create your own block, or at least one template.
Here is the short version using only a template.
Create the file app/design/frontend/base/default/template/homepage/categories.phtml with this content:

<?php
$rootId = Mage::app()->getStore()->getRootCategoryId();
$categories = Mage::getModel('catalog/category')->getCollection()
    ->addAttributeToSelect('*')
    ->addAttributeToFilter('parent_id', $rootId)
    ->setOrder('position')
    ->addAttributeToFilter('include_in_menu', 1) //this is needed if you want only the categories in the menu
    ->addAttributeToFilter('is_active', 1);

$_helper = $this->helper('catalog/output'); 
?>
<?php if ($categories->count() > 0) : ?>
<ul>
    <?php foreach ($categories as $category) : ?>
       <li>
           <div class="name">
              <a href="<?php echo $category->getUrl()?>" title="<?php echo $this->escapeHtml($category->getName())?>"><?php echo $category->getName()?></a>
           </div>
           <div class="image">
               <?php if ($category->getImageUrl()) :?>
                   <img src="<?php echo $category->getImageUrl()?>" alt="<?php echo $this->escapeHtml($category->getName())?>" />
               <?php endif;?>
           </div>
           <div class="description">
               <?php echo $_helper->categoryAttribute($category, $category->getDescription(), 'description') ?>
           </div>
       </li>
    <?php endforeach;?>
</ul>
<?php endif;?>

Now you need to add this to the homepage content:

{{block type="core/template" template="homepage/categories.phtml"}}

The markup of the template may need some modifications in order to make it a slider, but all the elements you need are there.

There is a cleaner method where you create you own block and move the code that retrieves the categories to a block method and call that method in the template. But the idea is the same.

I haven't tested the code so be careful at syntax errors.

Magento – How to add custom options for categories product sorting in magento admin

You can just add 2 product attributes with the names you want and make them available for sorting.
If you need a custom logic behind it rewrite the method Mage_Catalog_Model_Resource_Product_Collection::addAttributeToSort and add your own case section to handle your attributes.

Here is an example on how it's done for created_at. You can do something similar for your attributes.
