Jul 25, 2016 am 08:52 AM

  1. php;toolbar:false">/*public function actionReport()
  2. {
  3. $sql = "select * from {{goods}}";
  4. $criteria=new CDbCriteria();
  5. $result = Yii::app()->db->createCommand($sql)->query();
  6. $pages=new CPagination($result->rowCount);
  7. $pages->pageSize=2;
  8. $pages->applyLimit($criteria);
  9. $result=Yii::app()->db->createCommand($sql." LIMIT :offset,:limit");
  10. $result->bindValue(':offset', $pages->currentPage*$pages->pageSize);
  11. $result->bindValue(':limit', $pages->pageSize);
  12. $goodsInfo=$result->query();
  13. $this->render('index',array(
  14. 'goodsInfo'=>$goodsInfo,
  15. 'pages'=>$pages,
  16. ));
  17. }*/
复制代码
  1. foreach($goodsInfo as $v){
  2. ?>
  3. }
  4. ?>
  5. //分页widget代码:
  6. $this->widget('CLinkPager',array('pages'=>$pages));
  7. ?>
  8. 商品name 价格 更新时间
复制代码

方式二,使用自己的分页类来完成分页 1,控制器代码:

  1. public function actionIndex(){

  2. $goods_m=goods::model();

  3. //1.获得商品总的记录数目

  4. $cnt = $goods_m -> count();

  5. //2. 实例化分页类对象

  6. $page = new Page($cnt, 2);

  7. //3. 重新按照分页的样式拼装sql语句进行查询

  8. $sql = "select * from {{goods}} $page->limit";
  9. $goodsInfo = $goods_m -> findAllBySql($sql);

  10. //4. 获得分页页面列表(需要传递到视图模板里边显示)

  11. $pageList = $page->fpage();

  12. $this->renderPartial('index',array('goodsInfo'=>$goodsInfo,'pageList'=>$pageList));

  13. }

复制代码

2,视图代码:

  1. foreach($goodsInfo as $v){
  2. ?>
  3. }
  4. ?>
  5. echo $pageList;
  6. ?>
  7. 商品name price create_time
复制代码

分页类要放到能自动加载到的目录下就行;

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

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.
