如何在PHP代码WordPress中添加SportsEvent模式Json-ld代码

Question

我是一个初学者，试图将我网站的SportsEvent Schema代码组合在一起。我已经设法做到这一点。我创建了自定义字段并将其映射到架构属性。我似乎无法超越这一点。激活插件时出现错误-Parse error: syntax error, unexpected ';', expecting ')' in /home/uhkcj8xz70dl/public_html/wp-content/plugins/football-schema/football_schema.php on line 21

您在需要;的某些,中进行混合，因为它是一个值数组，并且在不需要一个endif时添加了一个。试试这个。

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
    }
}

那应该生成这样的JSON。尽管我的帖子没有一些post_meta来填写一些片段。

{
  "@context": "http://schema.org",
  "@type": "SportsEvent",
  "name": "some stuff",
  "description": "",

  "image": false,
  "competitor": [
    {

    {
