我创建了一个名为classperson.php的文件，我在其中声明了所有变量。 

<?php
class person1
{
    var $location;
    var $effective;
    var $training;
    var $treated;
    var $effort;
    var $information;
    var $recognition;
    var $valued;
    var $supervisor;
    var $informed;
    var $job;
    var $treats;
    var $satisfy;
    var $workgroup;
    var $utc;
    var $skills;

    function set_location($new_location)
    {
        $this->location=$new_location;
    }
    function get_location()
    {
        return $this->location;
    }


    function set_effective($new_effective)
    {
        $this->effective=$new_effective;
    }
    function get_effective()
    {
        return $this->effective;
    }



    function set_training($new_training)
    {
            $this->training=$new_training;
    }
    function get_training()
    {
            return $this->training;
    }



    function set_treated($new_treated)
    {
        $this->treated=$new_treated;
    }
    function get_treated()
    {
        return $this->treated;
    }




    function set_effort($new_effort)
    {
        $this->effort=$new_effort;
    }
    function get_effort()
    {
        return $this->effort;
    }



    function set_information($new_information)
    {
        $this->information=$new_information;
    }
    function get_information()
    {
            return $this->information;
    }



    function set_recognition($new_recognition)
    {
        $this->recognition=$new_recognition;
    }
    function get_recognition()
    {
        return $this->recognition;
    }



    function set_valued($new_valued)
    {
        $this->valued=$new_valued;
    }
    function get_valued()
    {
            return $this->valued;
    }



    function set_supervisor($new_supervisor)
    {
        $this->supervisor=$new_supervisor;
    }
    function get_supervisor()
    {
        return $this->supervisor;
    }



    function set_informed($new_informed)
    {
        $this->informed=$new_informed;
    }
    function get_informed()
    {
        return $this->informed;
    }



    function set_job($new_job)
    {
        $this->job=$new_job;
    }
    function get_job()
    {
            return $this->job;
    }



    function set_treats($new_treats)
    {
        $this->treats=$new_treats;
    }
    function get_treats()
    {
        return $this->treats;
    }



    function set_satisfy($new_satisfy)
    {
        $this->satisfy=$new_satisfy;
    }
    function get_satisfy()
    {
            return $this->satisfy;
    }



    function set_workgroup($new_workgroup)
    {
        $this->workgroup=$new_workgroup;
    }
    function get_workgroup()
    {
            return $this->workgroup;
    }



    function set_utc($new_utc)
    {
        $this->utc=$new_utc;
    }
    function get_utc()
    {
        return $this->utc;
    }



    function set_skills($new_skills)
    {
        $this->skills=$new_skills;
    }
    function get_skills()
    {
        return $this->skills;
    }
}
?>

后来我把这个文件包含在oopossurvey.php中。这是一个有5页的表格

我的问题是，这是在php中使用面向对象的概念来创建或创建表单的正确方法吗？或者我应该创建更多对象还是进行任何更改？

我试图在所有页面上包含文件classperson.php，但是当我使用下一个按钮时出现错误。

提前致谢

1 个答案:

答案 0 :(得分：3)

首先，您所谓的“页面”仅用于客户端，但对于PHP，它只是一个脚本。所以没有任何意义，例如多次执行session_start（），因为每次将数据发送到服务器时，脚本都会从头开始再次运行。当它到达当前页面的末尾时也不会停止运行。

其次，这个通过会话变量确定调查步骤的想法本身就有点生锈，而且没有正确实施。我很确定它不起作用（虽然我没有运行代码）。在会话中存储变量没什么不好，但我的建议是你应该以某种方式重新思考逻辑。例如，您可以在每个表单中使用一些隐藏的输入来检查用户的调查步骤，并在PHP文件中为每个页面添加一些switch{}()个案例。

第三，不要太困惑，你应该分开逻辑和表达。我的意思是 - 为所有表单使用单独的文件，并使用单独的文件接受来自用户的数据，将其写下来（如在您的示例中 - 在会话中），并选择接下来要显示的页面。通过这种方式，您可以更轻松地本地化错误，并且可以更好地解决问题。

至于你在PHP中使用类的问题：通常你应该只包括一次类，不需要重新包含它，例如在此文件中，您将处理所有逻辑。然后，您可以创建该类的实例并使用它。无论如何，我有一种感觉，你有点匆忙，在我看来，你早期开始使用OOP技术 - 最好一步一步走。尝试使这个脚本在没有类的情况下工作。什么时候它会将逻辑提取到一个类。那样你就能更好地理解一切：）
