我是一个初学者，试图为我的网站整理 SportsEvent Schema 代码。我已经做到了这一点。我创建了自定义字段并将它们映射到架构属性。我似乎无法超越这一点。当我激活插件时遇到错误 -Parse error: syntax error, unexpected ';', expecting ')' in /home/uhkcj8xz70dl/public_html/wp-content/plugins/football-schema/football_schema.php on line 21

你在一些;你需要的地方混合，,因为它是一个值数组，当你不需要一个时，你添加了一个endif。试试这个。
