如何以编程方式将架构代码插入wordpress，使其自动适用于目标post类型

我需要将这个模式json代码添加到WordPress中。我知道如何将此添加到个人帖子中，但我正在寻找一种情况，在这种情况下，我不需要为每个帖子手动添加此内容。我想插入代码，以便它能自动为我所针对的特定文章类型工作，在本例中，该类型是匹配的。我不知道该怎么办。我有一些自定义字段，我想用php在代码中插入这些字段，但我不确定这样做是否可行。请帮忙，谢谢

<script type="application/ld+json">
{
    "@context":"http://schema.org",
    "@type":"SportsEvent",
    "name": "Team A vs Team B",
    "description": "Team A vs Team B for League Match",
    "startDate": "2020-03-01",
    "endDate": "2020-03-01",
    "competitor": [
    {
        "@type": "SportsTeam",
        "name": "Team A",
        "image":"https://example.com/wp-content/uploads/2015/03/650.png"
        },
    {
        "@type": "SportsTeam",
        "name": "Team B",
        "image":"https://example.com/wp-content/uploads/2015/03/680.png"
    }
    ],
    "location": {
        "@type": "Place",
        "address": "Stadium of Team A"
    }
}
</script>

{
“@context”：”http://schema.org",
“@type”：“SportsEvent”，
“姓名”：“A队对B队”，
“描述”：“联赛A队对B队”，
“起始日期”：“2020-03-01”，
“截止日期”：“2020-03-01”，
“竞争对手”：[
{
“@type”：“SportsTeam”，
“姓名”：“A队”，
“图像”：https://example.com/wp-content/uploads/2015/03/650.png"
},
{
“@type”：“SportsTeam”，
“姓名”：“B队”，
“图像”：https://example.com/wp-content/uploads/2015/03/680.png"
}
],
“地点”：{
“@type”：“Place”，
“地址”：“A队体育场”
}
}

您可以将此函数添加到主题的

functions.php

文件中

function sports_event_schema() {
echo '
<script type="application/ld+json">
{
    "@context":"http://schema.org",
    "@type":"SportsEvent",
    "name": "Team A vs Team B",
    "description": "Team A vs Team B for League Match",
    "startDate": "2020-03-01",
    "endDate": "2020-03-01",
    "competitor": [
    {
        "@type": "SportsTeam",
        "name": "Team A",
        "image":"https://example.com/wp-content/uploads/2015/03/650.png"
        },
    {
        "@type": "SportsTeam",
        "name": "Team B",
        "image":"https://example.com/wp-content/uploads/2015/03/680.png"
    }
    ],
    "location": {
        "@type": "Place",
        "address": "Stadium of Team A"
    }
}
</script>';
}
if ( 'Matches' == get_post_type() ) {
 add_action('wp_footer', 'sports_event_schema');
}

{
“@context”：”http://schema.org",
“@type”：“SportsEvent”，
“姓名”：“A队对B队”，
“描述”：“联赛A队对B队”，
“起始日期”：“2020-03-01”，
“截止日期”：“2020-03-01”，
“竞争对手”：[
{
“@type”：“SportsTeam”，
“姓名”：“A队”，

},
{
“@type”：“SportsTeam”，
“姓名”：“B队”，
“图像”：https://example.com/wp-content/uploads/2015/03/680.png"
}
],
“地点”：{
“@type”：“Place”，
“地址”：“A队体育场”
}
}
';
}
if（'Matches'==get_post_type（））{
添加动作（'wp_页脚'，'sports_event_schema'）；
}

另一个选项是直接在页眉或页脚中添加json，并仅添加if语句：

<?php if ( 'Matches' == get_post_type() ) : ?>
<script type="application/ld+json">
{
    "@context":"http://schema.org",
    "@type":"SportsEvent",
    "name": "Team A vs Team B",
    "description": "Team A vs Team B for League Match",
    "startDate": "2020-03-01",
    "endDate": "2020-03-01",
    "competitor": [
    {
        "@type": "SportsTeam",
        "name": "Team A",
        "image":"https://example.com/wp-content/uploads/2015/03/650.png"
        },
    {
        "@type": "SportsTeam",
        "name": "Team B",
        "image":"https://example.com/wp-content/uploads/2015/03/680.png"
    }
    ],
    "location": {
        "@type": "Place",
        "address": "Stadium of Team A"
    }
}
</script>

<?php endif; ?>
