使用CakePHP框架實現資料篩選和排序的步驟

//在app/Model目录下创建StudentModel.php文件

class StudentModel extends AppModel {
    public function filterAndSortStudents($name, $age, $score, $sortField, $sortDirection) {
        $conditions = array();

        if (!empty($name)) {
            $conditions['name'] = $name;
        }

        if (!empty($age)) {
            $conditions['age'] = $age;
        }

        if (!empty($score)) {
            $conditions['score'] = $score;
        }

        $order = array($sortField => $sortDirection);

        return $this->find('all', array(
            'conditions' => $conditions,
            'order' => $order
        ));
    }
}

//在app/Controller目录下创建StudentsController.php文件

class StudentsController extends AppController {
    public $components = array('Session');
    public $uses = array('Student');

    public function index() {
        if ($this->request->is('post')) {
            $name = $this->request->data['name'];
            $age = $this->request->data['age'];
            $score = $this->request->data['score'];
            $sortField = $this->request->data['sortField'];
            $sortDirection = $this->request->data['sortDirection'];

            $students = $this->Student->filterAndSortStudents($name, $age, $score, $sortField, $sortDirection);

            $this->set('students', $students);
        }
    }
}

//在app/View/Students目录下创建index.ctp文件
