php - 表单不向mysql表插入信息？

Question

您好，我的论坛评论表单出现问题。基本上我试图允许用户阅读用户帖子并对其发表评论，表单数据应该插入到 mysql 中。

我需要插入的值是comment_id(用户的 session ID)和post_id(他们评论的帖子的ID)以及他们输入的内容。

由于某种原因，这没有被插入到 mysql 中，并且出现了我回显的成功消息，没有任何错误。有人可以告诉我哪里出了问题吗？

谢谢

这里缺少一些表名称:

$sql = "INSERT INTO ptb_forum_comments (comment_id, post_id, content) VALUES (NULL, '".$_SESSION['user_id']."', '".$profile_id."', '".$content."');";

如您所见，您有 3 个表名称和 4 个值。
