                'headline'         => get_the_title(),

?>
        <script type="application/ld+json"><?php echo wp_json_encode( $metadata ); ?></script>
<?php
    
$metadata = [
  "@context" => "https://schema.org",
  "@type" => "LiveBlogPosting",
  "name" => "storename",
  "image" => "https://staticqa.store.com/wp-content/themes/faf/images/store-logo.png",
  "@id" => $storeid,
  "url" => "",
  "telephone" => $storephone,
]
                
?>
        <script type="application/ld+json"><?php echo wp_json_encode( $metadata ); ?></script>
<?php
});
