How To Add SportsEvent Schema Json-ld Code Inside PHP Code WordPress

- 1 answer

I am a beginner trying to put together SportsEvent Schema code for my website. I have managed to get to this point. I created custom fields and mapped them to the Schema Properties. I can't seem to get past this point. I'm running into an error when I activate the plugin - Parse error: syntax error, unexpected ';', expecting ')' in /home/uhkcj8xz70dl/public_html/wp-content/plugins/football-schema/football_schema.php on line 21

You're mixing in some ; where you need , because it's an array of values and you added an endif when you didn't need one. Try this.

function addschema() //Function for Schema.org
{
    global $post;
    if (is_singular('post')) { //only for post type matches
        $schema_sportsevent = array(
            '@context'  => "http://schema.org",
            '@type'     => "SportsEvent",
            'name' => get_the_title($post->ID),
            'description' => get_the_content($post->ID),
            'url' => get_permalink(),
            'startDate' => get_post_meta( get_the_ID(), 'start_date' ),
            'endDate'=> get_post_meta( get_the_ID(), 'end_date' ),
            'image'   => get_the_post_thumbnail_url($post->ID),

            'competitor' => array(array(
                '@type' => "SportsTeam",
                'name'   => "Team A",
                'image'   => get_post_meta( get_the_ID(), 'logo_left' )),
                array('@type' => "SportsTeam",
                'name'   => "Team B",
                'image'   => get_post_meta( get_the_ID(), 'logo_left' ))
            ),


            'location' => array(
                '@type' => "Place",
                'name'   => get_post_meta( get_the_ID(), 'venue_name' ),
                'address' => array(
                '@type' => "PostalAddress",
                'postalCode'   => get_post_meta( get_the_ID(), 'zip_postal_code' ),
                'streetAddress'   => get_post_meta( get_the_ID(), 'street_address' ),
                'addressLocality'   => get_post_meta( get_the_ID(), 'locality_city' ),
                'addressRegion'   => get_post_meta( get_the_ID(), 'address_region' ),
                'addressCountry'   => get_post_meta( get_the_ID(), 'country' ),
            )
            )
        );
        echo '<script type="application/ld+json">' . json_encode($schema_sportsevent) . '</script>'; 
    //encode schema for matches
    }
}

That should generate JSON like this. Although my post didn't have some of the post_meta to fill in some of the pieces.

{
  "@context": "http://schema.org",
  "@type": "SportsEvent",
  "name": "some stuff",
  "description": "",
  "url": "http://192.168.33.10/wordpress/blog/2019/11/28/some-stuff/",
  "startDate": [],
  "endDate": [],
  "image": false,
  "competitor": [
    {
      "@type": "SportsTeam",
      "name": "Team A",
      "image": []
    },
    {
      "@type": "SportsTeam",
      "name": "Team B",
      "image": []
    }
  ],
  "location": {
    "@type": "Place",
    "name": [],
    "address": {
      "@type": "PostalAddress",
      "postalCode": [],
      "streetAddress": [],
      "addressLocality": [],
      "addressRegion": [],
      "addressCountry": []
    }
  }
}
