ThinkPHP实现动态包含文件的方法_php实例
本文实例讲述了ThinkPHP实现动态包含文件的方法。分享给大家供大家参考。具体分析如下:
问题描述:在做项目的时候遇到问题,也是很常见的问题,一般主页包含头部和脚步,为了方便管理,这些都需要使用包含文件来实现,ThinkPHP提供了包含文件的方法,以上是最简单的包含的操作的方式,但是在运行的过程中我发现,在请求的时候只是请求的是模板文件,也就是所谓的静态包含,但是如果遇到菜单是动态生成的就很难办了.
在网上找到一个解决办法:使用Widget
1、我们在页面中实现一个分类显示的Widget,首先我们要实现我们首先定义一个Widget控制器层 CateWidget,如下:
public function menu(){
return 'menuWidget';
}
}
注意是在Widget包中定义,和一般的Action还是有区别的
2、然后,我们在模版中通过R方法调用这个Widget(扩展Widget方式在模版中使用的是W方法),如果对R函数不了解的参考这里.(http://www.thinkphp.cn/info/134.html)
{:R('Cate/Menu','','Widget')}
执行后的输出结果是:menuWidget
3、如果,CateWidget类的menu方法改成:
public function menu(){
echo 'menuWidget';
}
}
4、模版中的用法则需要改成:
5、如果需要在调用Widget的时候 使用参数,可以这样定义:
public function menu($id,$name){
echo $id.':'.$name;
}
}
6、模版中的参数调用,使用:
则会输出 5:thinkphp
7、来一个复杂一点的例子:
public function menu(){
$menu = M('Cate')->getField('id,title');
$this->assign('menu',$menu);
$this->display('Cate:menu');
}
}
8、CateWiget类渲染了一个模版文件Tpl/Cate/menu.html,调用模版的灵活也是使用这种方式实现Widget的区别(Widget扩展方式中需要调用renderFile方法渲染模版)。
在menu.html模版文件中的用法:{$key}:{$title}
希望本文所述对大家的ThinkPHP框架程序设计有所帮助。

When creating a virtual machine, you will be asked to select a disk type, you can select fixed disk or dynamic disk. What if you choose fixed disks and later realize you need dynamic disks, or vice versa? Good! You can convert one to the other. In this post, we will see how to convert VirtualBox fixed disk to dynamic disk and vice versa. A dynamic disk is a virtual hard disk that initially has a small size and grows in size as you store data in the virtual machine. Dynamic disks are very efficient at saving storage space because they only take up as much host storage space as needed. However, as disk capacity expands, your computer's performance may be slightly affected. Fixed disks and dynamic disks are commonly used in virtual machines

Quark Netdisk and Baidu Netdisk are currently the most commonly used Netdisk software for storing files. If you want to save the files in Quark Netdisk to Baidu Netdisk, how do you do it? In this issue, the editor has compiled the tutorial steps for transferring files from Quark Network Disk computer to Baidu Network Disk. Let’s take a look at how to operate it. How to save Quark network disk files to Baidu network disk? To transfer files from Quark Network Disk to Baidu Network Disk, you first need to download the required files from Quark Network Disk, then select the target folder in the Baidu Network Disk client and open it. Then, drag and drop the files downloaded from Quark Cloud Disk into the folder opened by the Baidu Cloud Disk client, or use the upload function to add the files to Baidu Cloud Disk. Make sure to check whether the file was successfully transferred in Baidu Cloud Disk after the upload is completed. That's it

When deleting or decompressing a folder on your computer, sometimes a prompt dialog box "Error 0x80004005: Unspecified Error" will pop up. How should you solve this situation? There are actually many reasons why the error code 0x80004005 is prompted, but most of them are caused by viruses. We can re-register the dll to solve the problem. Below, the editor will explain to you the experience of handling the 0x80004005 error code. Some users are prompted with error code 0X80004005 when using their computers. The 0x80004005 error is mainly caused by the computer not correctly registering certain dynamic link library files, or by a firewall that does not allow HTTPS connections between the computer and the Internet. So how about

Recently, many netizens have asked the editor, what is the file hiberfil.sys? Can hiberfil.sys take up a lot of C drive space and be deleted? The editor can tell you that the hiberfil.sys file can be deleted. Let’s take a look at the details below. hiberfil.sys is a hidden file in the Windows system and also a system hibernation file. It is usually stored in the root directory of the C drive, and its size is equivalent to the size of the system's installed memory. This file is used when the computer is hibernated and contains the memory data of the current system so that it can be quickly restored to the previous state during recovery. Since its size is equal to the memory capacity, it may take up a larger amount of hard drive space. hiber
