ThinkPHP实现在可视化后台管理永久修改前端视图页面的方法
我一直以来就在纳闷意见事情,就是像csdn一样,用户可以自己去修改自己的主页样式,而且是永久性的修改,很多的地方都请到了,把视图样式交给用户这也是未来发展的趋势,想QQ空间装扮,甚至一些建站程序的后台都是这样的,所以,把这个原理明白是非常重要的。
首先这个显然不可能通过前端的来实现,因为前段的东西到用户那里最终是放到内存里面,内存是有易失性,那么就应该是放在后台,同样的,我们也不可能去直接修改后台文件,这样代价非常大,那么就要把他们放入数据库中,数据库中的数据时存在硬盘里面的,不容易丢失,而且通过后台文件也很容易操作,这样的话,思路就来了。
在后台的可视化管理界面,存放各种样式的按钮,表单等,包括具体修改的页面,在数据库里面,存放的是前台视图的样式数据,这中间是缺少一个连接的,但smarty完美的解决了这个问题,而且分离了数据,修改就是修改的数据库的数据,提取就是提取数据库的样式,这就是核心原理。
下面有我的一份实例代码仅供参考:
<?phpnamespace Home\Controller;use Think\Controller;class TestController extends Controller { public function test1(){ $info=D("style"); $temp=$info->select(); $info->id='2'; $info->value=$_POST[value]; $info->save(); $bg=$temp[1]['value']; $size=$temp[4]['value']; echo $bg; echo "<br>"; echo $size; $this->assign(bg,$bg); $this->assign(size,$size); $this->display(); }}
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8"> <title>bg测试</title> <font style="font-size: {$size}">测试赛</font>

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
