代码点火器：如果'null'值设置为 0

Question

在我想要的全部，文件是控制器，或者我应该在模型中进行操作？

public function newUser(){
    $param['name'] = $this->input->post("name");
    $param['email'] = $this->input->post("email");
    $param['user'] = $this->input->post("user");
    $param['password'] = sha1($this->input->post("password"));
    $param['state'] = $this->input->post("state"); //<-- this value is a checkbox, if is unckecked the value became 'null'. What I want is to change that 'null' value to 0 before to send to the database.
    $this->mdatabase->newUser($param);
}

谢谢：d。

通过使用 isset，我们可以检查变量是否设置为任何值，或者为null。然后，我们可以应用逻辑来相应地分配您的值。

 public function newUser(){
        $param['name'] = $this->input->post("name");
        $param['email'] = $this->input->post("email");
        $param['user'] = $this->input->post("user");
        $param['password'] = sha1($this->input->post("password"));
        if(!isset($param['state'])
           $param['state'] = 0;
        else if(isset($param['state'])
           $param['state'] = $this->input->post("state");
        $this->mdatabase->newUser($param);
    }

应该为您努力。让我知道它的工作原理。

编辑：有一个语法错误。现在应该工作。
