Layout Handles

The Observer/LayoutLoadBefore.php observer dynamically adds a layout handle to every blog page request. These handles allow targeted layout customization per page type.

Layout Handles

Handle	Page	Layout File
`orangecollar_blog_index`	Blog post listing	`view/frontend/layout/orangecollar_blog_index.xml`
`orangecollar_post_view`	Single post page	`view/frontend/layout/orangecollar_post_view.xml`
`orangecollar_category_view`	Category archive	`view/frontend/layout/orangecollar_category_view.xml`
`orangecollar_tag_view`	Tag archive	`view/frontend/layout/orangecollar_tag_view.xml`
`orangecollar_author_view`	Author archive	`view/frontend/layout/orangecollar_author_view.xml`
`orangecollar_search_results`	Search results	`view/frontend/layout/orangecollar_search_results.xml`

How Handles Are Added

The handle name is constructed as orangecollar_{controller}_{action}:

Controller name: the request controller name (set by the Router based on the URL pattern matched)
Action: the controller action name (index, view, results)

For the post view controller, the handle is orangecollar_post_view. For the blog index controller, it is orangecollar_blog_index.

Using Layout Handles in Your Theme

To add content to the blog listing page sidebar in your theme:

File: app/design/frontend/Your/Theme/OrangeCollar_WordPressIntegration/layout/orangecollar_blog_index.xml

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <body>
        <referenceContainer name="sidebar.main">
            <block class="OrangeCollar\WordPressIntegration\Block\Sidebar\Categories"
                   name="blog.sidebar.categories"
                   template="OrangeCollar_WordPressIntegration::sidebar/categories.phtml"
                   after="-"/>
        </referenceContainer>
    </body>
</page>

To apply changes to all blog page types at once, use a layout update that references all six handles.
