如何解决带有评论类型评论的问题
| 大家好,我想知道我是否可以在我为一个项目构建的网站上获得一些帮助。它几乎完成了,但是我正在努力进行其中的一部分,这基本上是评论。 我正在创建一个电影评论网站,有点像IMDB.com,但我的课程只适合上课,但是我真的很努力地工作。 对我来说,理想的情况是让某人能够键入他们想要搜索的电影,然后在他们提交后将他们带到另一个页面。在该页面上,电影信息,例如电影名称,描述,类型,等级等。然后在其下,回顾人们对电影的看法。但是,我无法获得的一件事是,当有人键入Avatar时,会出现电影评论,但是当他们键入Ghost Rider时,会出现完全相同的评论,如果可以的话,我希望他们分开。 对于我的桌子, 电影MovieID,Description,Rating,Genre
评论
ReviewID,Name,Review,MovieID
我在这方面一直处于停滞状态,这有点困扰我,我已经看了很多地方,但仍然找不到我要寻找的东西。
这是我的代码,很遗憾地通知我,我在PHP或编程方面不是很擅长。而且所有这些操作都是在Dreamweaver中完成的,因此,如果看上去很乱,那就是为什么。

解决方法
评论表包含评论,对不对?我可以看到那里有一个MovieID列,因此您应该能够以条件
WHERE MovieID = \'$current_movie_id\'
查询数据库,以便仅获取特定电影的评论。
