yii?删除约束
数据表category: category_id category_titlesubcategory:subcategory_id subcategory_category(与category_id关联) 在删除category表的数据时,要确保category_id在subcategory_category中不存在控制器: public function actionDelete($id) { if(Yii::app()->request->isPostRequest) { $model=$this->loadModel($id); $results = Category::getSubCategorySet($id); //查找当前category_id是否在subcategory_category中存在 //存在的话,就要提醒用户 //我这里是通过抛异常来提醒用户的,但我不想要错误编号的出现 //或者你们有更好的方法可以告诉我 if($results!=0){ throw new CHttpException(400,'This title is use on sub-category management'); }else{ $model = $this->loadModel($id); $model->category_status = 'D'; if ($model->validate()) { $model->save(); } // $model->delete(); // if AJAX request (triggered by deletion via admin grid view), we should not redirect the browser if(!isset($_GET['ajax'])) $this->redirect(isset($_POST['returnUrl']) ? $_POST['returnUrl'] : array('admin')); } }

你改下异常的那个view去掉错误编号好了

不是异常之后还是会显示一些内容吗?会有个默认的view,叫error还是什么的.
在那个view里把错误标号不显示是不是可以满足你要求?
SiteController.phppublic function actionError() { if($error=Yii::app()->errorHandler->error) { if(Yii::app()->request->isAjaxRequest) echo $error['message']; //去掉这个就不会显示错误信息 但错误编号还在 Error:400 else $this->render('error', $error); } }site视图下有 error.php 整个删掉都没影响

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,

Article discusses late static binding (LSB) in PHP, introduced in PHP 5.3, allowing runtime resolution of static method calls for more flexible inheritance.Main issue: LSB vs. traditional polymorphism; LSB's practical applications and potential perfo

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.

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.

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.
