下载错误php之前发送电子邮件

Question

我在下载错误之前遇到了电子邮件问题

Warning: count(): Parameter must be an array or an object that implements Countable in /wp-content/plugins/email-before-download/includes/class-email-before-download-db.php on line 56

如何解决此问题？

Answer 1

为防止该错误。替换

 if (count($query) > 0) { 

与

 if (is_array($query) && count($query) > 0) {
