JSON+LD Schema

This module helps you dynamically create schemas from within your templates. Each schema can be configured to meet your requirements. You can even add your own ProcessWire schema classes to the module.

MarkupJsonLDSchema Module v0.1.1

General information

This module is all about arrays, either PHP or JSON+LD. JSON+LD schema arrays give your web pages a vastly improved chance of high visibility in SERPs and, at Google's whim, deliver more engaging results than simply a title, link and brief description.

While the inherent structure of a schema is pre-defined, there are 1000s of combinations.

This module helps you dynamically create schemas from within your templates. Each schema can be configured to meet your requirements. You can even add your own ProcessWire schema classes to the module.

There are plenty of reference sites and guides to learn more about json+ld schemas. Try these for starters:

• https://developers.google.com/schemas/
• http://jsonld.com
• https://www.jamesdflynn.com/json-ld-schema-generator/

There are also a few very informative posts in the ProcessWire forums.

Installation

• Available on GitHub at https://github.com/clipmagic/MarkupJsonLDSchema
• Login to ProcessWire > go to Modules > click "Refresh". You should see a note that a new module was found. Install the module. Configuration is not compulsory. It's simply a shortcut to populating an Organization or Business type schema. Worth it though!

Usage

Basic usage

In your template:

<?php $jsonld = $modules->get('MarkupJsonLDSchema'); ?>
 <script type="application/ld+json">
 	<?php $jsonld->render('LocalBusiness'); ?>
 </script>

This will output a LocalBusiness schema as per the data saved in the module configuration page.

Overriding schema elements

A more complex example using the $options array in _footer.php:

<?php
    $jsonld = $modules->get('MarkupJsonLDSchema');
    $options = array(
        'logo' => $pages->get(1)->images->first->width(200)
    );
 ?>
<script type="application/ld+json">
<?php
    switch ($page->template) {
        case 'home':
            echo $jsonld->render('WebSite', $options);
            echo $jsonld->render('LocalBusiness', $options);
            break;
        case 'blog-post':
            echo $jsonld->render('Article');
            echo  $jsonld->render('BreadcrumbList');
            break;
        default:
            echo $jsonld->render('WebPage', $options);
            echo $jsonld->render('LocalBusiness', $options);
            echo  $jsonld->render('BreadcrumbList');
            break;
         }
    ?>
</script>

Any value in the default schema may be overwritten in the $options array, eg:

<?php 
    $jsonld = $modules->get('MarkupJsonLDSchema');
    $options["@type"] = "RealEstateAgent"
?>
<script type="application/ld+json">
    <?php $jsonld->render('LocalBusiness',$options); ?>
</script>

Would render the schema "@type" as "RealEstateAgent" instead of "LocalBusiness".

Custom schema elements

You can add to the pre-defined schema arrays with the use of the 'custom' key in the $options array, eg:

$jsonld = $modules->get("MarkupJsonLDSchema");
$options = array();
$options["custom"] = array (
  "foo" => "bar",
  "foo2 => array (
  		"@type" => "FooBar",
  		"name" => "Mary Contrary",
  )
)
<script type="application/ld+json">
  <?php $jsonld->render('LocalBusiness',$options); ?>
</script>

Would render the default LocalBusiness schema plus the items in the $options["custom"] array.
