Answer 1

public function createEmployee(){
      $code = $_POST['emp_code'];
      $s_name = $_POST['name_emp'];
      $hiring_date = $_POST['hiringdate'];
      $salary = $_POST['salary_emp'];
      $nb_hours = $_POST['nb_hours'];
      $taux_remun = $_POST['t_remun'];

         $query = "INSERT INTO employees (id, code, s_name, hiring_date, salary, nb_hours, taux_remun) VALUES ('', :code, :s_name, :hiring_date, :salary, :nb_hours, :taux_remun)";

         $this->conn->query($query);
         $this->conn->bind('code', $this->code);
         $this->conn->bind('s_name', $this->s_name);
         $this->conn->bind('hiring_date', $this->hiring_date);
         $this->conn->bind('salary', $this->salary);
         $this->conn->bind('nb_hours', $this->nb_hours);
         $this->conn->bind('taux_remun', $this->taux_remun);

         $this->conn->execute();
         return $this->conn->rowCount();

   }

在插入查询中，您输入了id，它的值是''，但是由于字段是自动递增的，因此没有意义，因为您将其放在数据库中时认为该''字段是用于自动递增的代码，因此在您的插入查询中删除ID并删除''，然后直接从代码开始。
