Hooks

The starter theme offers a handful of hooks and filters to tap into and customize WordPress functionality. Here is a list of what we include and how to use it in your theme.

add_og_tags()​

Sometimes a client don't use Yoast SEO or another SEO plugin. In those cases, we still want to make sure they have reliable meta tags in place to display robust post cards when content is shared via Facebook, Twitter, etc.

This hook first checks to see if Yoast is active – we don't need to output 2x meta tags.

If Yoast isn't active, we build our meta tags based on a set of conditions as we go:

  • Single posts and pages (but not the front page)
  • Category, Tag, and Custom Taxonomy archives
  • Search Results
  • Blog archive
  • Front page
  • Post Type archives
  • Media pages

Output:

<meta property="og:title" content="Featured Image (Vertical) - wd_s" />
<meta
  property="og:description"
  content="This post should display a featured image, if the theme supports it. Non-square images can provide some unique styling issues. This post tests a vertical featured image."
/>
<meta
  property="og:url"
  content="https://wdunderscores.test/2013/03/15/featured-image-vertical/"
/>
<meta
  property="og:image"
  content="https://wdunderscores.test/wp-content/uploads/2013/03/featured-image-vertical.jpg"
/>
<meta property="og:site_name" content="wd_s" />
<meta property="og:type" content="article" />
<meta
  name="description"
  content="This post should display a featured image, if the theme supports it. Non-square images can provide some unique styling issues. This post tests a vertical featured image."
/>

body_classes()​

Add classes to the <body> tag.

Usage: add_filter( 'body_class', __NAMESPACE__ . '\body_classes' );

Output: Adds class names to the <body> tag based on the location, template type, or browser type.
