Structured Data

Structured Data helper classes for WordPress themes.

Supports the following data types:

Installation

You can install the package via Composer:

composer require mindkomm/theme-lib-structured-data

Usage

Put the generated output into the <head> of your HTML.

add_action( 'wp_head', function() {
    // Local Business
    $local_business = new Theme\Structured_Data\Local_Business( $options );
    echo $local_business->generate_jsonld();

    // Website
    $website = new Theme\Structured_Data\Website();
    echo $website->generate_jsonld();

    // Logo
    $logo = new Theme\Structured_Data\Logo( $logo_url );
    echo $logo->generate_jsonld();

    // Social profiles
    $social_profiles = new Theme\Structured_Data\Social_Profile( $social_profiles );
    echo $social_profiles->generate_jsonld();
} );

Website

The class checks if it can find a search.php file in your theme directory and will include a potential search action property accordingly. If you want to have more control over this, you can pass a boolean to the generate_jsonld() function:

// Use SearchAction, ignore check for search.php file.
echo $website->generate_jsonld( true );

Local Business

A Local Business entry can take a lot of data. The following types of data are supported:

Contact Data – Address, phone number, email address, etc.
Geocodes – The latitude and longitude of where the business is located on the map.
Opening hours – The opening hours of a business.

You need to pass this data when you instantiate the class in the form of an array. Here’s an overview over all the options you can pass in:

Usage remarks

It’s up to you how you want to build this data. You can set up a customizer page or you could use an ACF Options Page as an interface to edit these values.
If you don’t provide a value for something, it will be ignored in the output.
Always check your output with the Structured Data Testing Tool.
