前台如何实现与后台交互,以及如何快速建站!!!

只理解单个页面如何操作,在html混编PHP,然后提交给数据库进行显示。

后台就完蛋了,我的理解是不是也在HTML里面加PHP语句,然后通过后台操作,(别说MVC什么的好吗?)举例说明吧。

有个前台页面,只有一行导航栏,比如说有,"你好"“我好”“他好”。

在这个标签里面嵌入 里面写一个变量, 然后后台点击删除的话, 这里面就木有值了。

我的理解和表达都有问题,在别人看来很简单的问题,我都喜欢把其复杂化,PHP MYSQL的基础已经学完了,
最近要求写一个小项目,可是我理解不透,跟讲师沟通过,也一直在“嗯嗯嗯”的回复,
讲师一走,还是没有理解。 希望有前辈能够深入浅出的说一哈。

如果您硬要说让我去看源码,那我也没什么好说的,我下的最简单的都1M多,而且都是用的MVC框架写的,
这让我如何看的懂。可以不负责任的告诉您,您给我讲清楚这个,我大致就能理解MVC了。 

如果可以顺便帮我解答一下MVC概念,

V是视图,C是控制器,M是模块,
从V提交动作,传达给C,然后通过模块执行返还给C,然后再给相应的动作。

问:
1)我看到的是V吗?(因为我看到的肯定不是V,它只是个模板,这个V是怎么跟前台页面交互的)。

再问:
     最近有一个小项目,我只有4个子“无从下手”,再多四个字,“欲哭无泪”。
1)听说,如果喜欢哪个前台,可以直接保存下来,然后在基础上进行修改,是这样吗?
2)我写不出后台,我现在就敲了20行代码,一个登陆界面,匹配用户后能勉强跳到后台管理页面(空白页,下面就不会写了, 啊啊 ,我是不是特别笨啊)。。。


最近,我又是看MVC,又是看TP,希望能从TP上面理解透MVC,可越看越蛋疼,
还让用MVC实现,我日日日日日。

MVC回答不回答这个不是重点,希望您的回答能让我彻底理解后台跟前台的关系。

题外话“后台不就是增删改查吗”。。。我呸,说的轻巧。

如果您觉得我的基础不够踏实,或者建言让我重新看下基础课程,我觉得也不错,
但是时间紧凑,况且这次的项目就是将以前的知识点结合一下,
如果可能的话,我希望是折中一点,您给我推荐几篇建站俗称的帖子,
能让我明白前后台关系。

最蛋碎的是竟然在搜索引擎搜不到此类文章,是我的关键字不对还是太基础、

讲师是哪个大师...

先不管那么多什么了,你大约应该现在要学的东西是

ajax
你可以搜索一下 jquery 的ajax
也就是使用jquery(js) 点击后触发事件 ajax 获取后台值 这类交互工作.

流程是这样的 html ->click->ajax->php callback->modify html

MVC只是针对大型网站比较方便,易于维护,如果你对MVC架构不是很清楚,对开源的MVC框架不熟悉,自己基础不是很好,我建议你还是用源生的代码去做网站,理解MVC是什么东西,网上有很多回答,至于楼主没有找到明确的答案,我表示不解。

休要质疑我讲师,
您可能有点误会,我们没有学到那里,进度有一个月,MYSQL+PHP基础都已经讲完了,所以有个中级项目,
其实完全不能怪我们讲师,班上N个同学,他们都能懂,就我不会,个人资质问题,jquery+ajax是未来的课程,首先我不会,其次时间也没那么多,还有几天啊。。。。我想要模板,我想要类库,

我需要顿悟,网上别说MVC的资料,PHP都堆成山,
资料虽然多,可我就是没有理解。。。。啊啊啊 啊啊

MVC只是一个架构、一个思维上的约束,既然你已经 只理解单个页面如何操作,在html混编PHP,然后提交给数据库进行显示。
那么你的 读取数据库就是 M,生成页面就是 V,解释传入的数据并形成相应操作就是 C

就你的例子:
有个前台页面,只有一行导航栏,比如说有,"你好"“我好”“他好”。
在这个标签里面嵌入 里面写一个变量, 然后后台点击删除的话, 这里面就木有值了。

前台和后台是分开运行的,所以你需要有一个前后台沟通的机制,为此可通过数据库
当前台的“变量”是从数据库中读取的时,那么后台就可以通过对数据库中的内容的处理来控制前台的行为了

今天讲师单独给我开了个小灶,最后我的理解就是,不分前后台,
前台就是只有一个查询的结果,但是前台也需要连接数据库。然后查询输出到页面,
后台比前台多了些功能,比如删除,增加等。MVC,我再看看视频吧,太痛苦了。

除了数据库外,java后台和jsp页面本身不可以交互吗?

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1? Apr 17, 2025 am 12:06 AM

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values ​​to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
