有评论类型评论的问题

嘿伙计们，我想知道我是否可以获得一些我正在为一个项目建设的网站的帮助。它已接近完成但我正在努力完成一部分，这基本上就是评论。

我正在创建一个电影评论网站，有点像IMDB.com，但我的只是为了上课，但我真的很挣扎于我真正想要工作的部分。

对我来说理想的情况是，有人能够输入他们想要搜索的电影，然后在他们推送提交后，他们会被带到另一页。在该页面上的电影信息，如电影名称，描述，流派，评级等......然后在其下面，回顾人们对电影的看法。但是，我不能得到的一件事就是当有人在“阿凡达”中输入电影评论时，但是当他们输入Ghost Rider时，会出现完全相同的评论，如果有意义，我希望它们是分开的。

对于我的桌子，

  • 电影 

    MovieID, Description, Rating, Genre

  • 评论 

    ReviewID, Name, Review, MovieID

对于这部分我只是处于停滞状态，它有点烦我，我看了很多地方，仍然无法找到我正在寻找的东西。 这是我的代码，我很遗憾地告诉我，我不擅长PHP或编程。所有这些都是在Dreamweaver中完成的，所以如果它看起来很乱，那就是原因。

答案 0 :(得分：2)

评论表包含评论，对吗？我可以看到你有一个MovieID列，所以你应该能够使用条件WHERE MovieID = '$current_movie_id'查询数据库，只获得某部电影的评论。
