Codeigniter控制器controller继承问题实例分析,codeigniter控制器
本文实例讲述了Codeigniter控制器controller继承问题。分享给大家供大家参考,具体如下:
在项目中经常用到这样一种情况,后台中每个页面都要判断Session来确定用户是否登陆状态.对于在Codeigniter中,那么就会考虑每个控制器继承一个公用控制器。
比如:AdminBase 为应用后台的公用的控制器,在每一个应用后台控制器里面都来继承公共的AdminBase ,但是同时要确保AdminBase 也是继承CI_Controller的。
前台HomeBase也是同样的道理。
具体实现很简单,只要在application/core下面新建MY_Controller.php,如下
(MY_是可配置的,application/config/config.php 文件并找到这一项:$config['subclass_prefix'] = 'MY_';)
class MY_Controller extends CI_Controller { function __construct() { parent::__construct(); } } class AdminBase extends MY_Controller { function __construct() { parent::__construct(); ...... } ...... } class HomeBase extends MY_Controller { function __construct() { parent::__construct(); ...... } ...... }
然后在application/controllers里面的控制器就可以继承了,比如application/controllers/admin/blog.php中
class Blog extends AdminBase { function __construct() { parent::__construct(); ...... } ...... }

Since Windows has become the gaming platform of choice, it's even more important to identify its gaming-oriented features. One of them is the ability to calibrate an Xbox One controller on Windows 11. With built-in manual calibration, you can get rid of drift, random movement, or performance issues and effectively align the X, Y, and Z axes. If the available options don't work, you can always use a third-party Xbox One controller calibration tool. Let’s find out! How do I calibrate my Xbox controller on Windows 11? Before proceeding, make sure you connect your controller to your computer and update your Xbox One controller's drivers. While you're at it, also install any available firmware updates. 1. Use Wind

In function inheritance, use "base class pointer" and "derived class pointer" to understand the inheritance mechanism: when the base class pointer points to the derived class object, upward transformation is performed and only the base class members are accessed. When a derived class pointer points to a base class object, a downward cast is performed (unsafe) and must be used with caution.

Learning Laravel from scratch: Detailed explanation of controller method invocation In the development of Laravel, controller is a very important concept. The controller serves as a bridge between the model and the view, responsible for processing requests from routes and returning corresponding data to the view for display. Methods in controllers can be called by routes. This article will introduce in detail how to write and call methods in controllers, and will provide specific code examples. First, we need to create a controller. You can use the Artisan command line tool to create

Inheritance and polymorphism affect the coupling of classes: Inheritance increases coupling because the derived class depends on the base class. Polymorphism reduces coupling because objects can respond to messages in a consistent manner through virtual functions and base class pointers. Best practices include using inheritance sparingly, defining public interfaces, avoiding adding data members to base classes, and decoupling classes through dependency injection. A practical example showing how to use polymorphism and dependency injection to reduce coupling in a bank account application.

Inheritance error debugging tips: Ensure correct inheritance relationships. Use the debugger to step through the code and examine variable values. Make sure to use the virtual modifier correctly. Examine the inheritance diamond problem caused by hidden inheritance. Check for unimplemented pure virtual functions in abstract classes.

Encapsulation technology and application encapsulation in PHP is an important concept in object-oriented programming. It refers to encapsulating data and operations on data together in order to provide a unified access interface to external programs. In PHP, encapsulation can be achieved through access control modifiers and class definitions. This article will introduce encapsulation technology in PHP and its application scenarios, and provide some specific code examples. 1. Encapsulated access control modifiers In PHP, encapsulation is mainly achieved through access control modifiers. PHP provides three access control modifiers,

Detailed explanation of C++ function inheritance: Master the relationship between "is-a" and "has-a" What is function inheritance? Function inheritance is a technique in C++ that associates methods defined in a derived class with methods defined in a base class. It allows derived classes to access and override methods of the base class, thereby extending the functionality of the base class. "is-a" and "has-a" relationships In function inheritance, the "is-a" relationship means that the derived class is a subtype of the base class, that is, the derived class "inherits" the characteristics and behavior of the base class. The "has-a" relationship means that the derived class contains a reference or pointer to the base class object, that is, the derived class "owns" the base class object. SyntaxThe following is the syntax for how to implement function inheritance: classDerivedClass:pu

In the Laravel learning guide, calling controller methods is a very important topic. Controllers act as a bridge between routing and models and play a vital role in the application. This article will introduce the best practices for controller method calling and provide specific code examples to help readers better understand. First, let's understand the basic structure of controller methods. In Laravel, controller classes are usually stored in the app/Http/Controllers directory. Each controller class contains multiple
