Codeigniter controller controller inheritance problem example analysis, codeigniter controller
This article describes the Codeigniter controller controller inheritance problem with an example. Share it with everyone for your reference, the details are as follows:
In projects, there is often a situation where each page in the background must judge the Session to determine whether the user is logged in. For Codeigniter, each controller will be considered to inherit a common controller.
For example: AdminBase is the public controller of the application background. Each application background controller inherits the public AdminBase, but at the same time, make sure that AdminBase also inherits CI_Controller.
The same is true for HomeBase at the front desk.
The specific implementation is very simple, just create a new MY_Controller.php under application/core, as follows
(MY_ is configurable, go to application/config/config.php file and find this item: $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(); ...... } ...... }
Then the controller in application/controllers can be inherited, such as application/controllers/admin/blog.php
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.

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

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,

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
