thinkphp模板使用问题
在thinkphp里面结合使用smarty模板,都已经配置好了,在IndexAction.class.php文件里面使用$this->display("login")没有问题,但是另外一个文件DefaultAction.class.php文件里面同样使用,则出现以下问题:
Fatal error: Call to a member function display() on a non-object in E:\php\AppServ\www\DLP\ThinkPHP\Lib\Think\Core\Action.class.php on line 103
其中Action.class.php那边的代码是:
protected function display($templateFile='',$charset='',$contentType='text/html')
{echo $templateFile;
if(false === $templateFile) {
$this->showTrace();
}else{
$this->view->display($templateFile,$charset,$contentType);
}
}
有没有出现过同样问题的大哥,给个帮助...
回复讨论(解决方案)
应该是 DefaultAction.class.php 这个文件的问题,你看下它的类名以及继承类名是否正确
应该不是tp里的错误,而是你控器中哪个display引用出了问题,好好检查一下。
我也出现过,因为Action用了构造函数
function __construct()
{
//content
}
在TP中要用
function __construct()
{
parent::__construct;
}

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
