我在一个项目中使用三个文件：index.php、class.php和styles.css.

我的所有函数都驻留在 class.php 文件中的 php 类中：

<?php

class Club
{
    //Private Data
    private $HostName;      //typically "localhost"
    private $UserId;
    private $Password;
    private $DBName;
    private $Con;           //MySQL Connection
    //Public Methods
    //Constructor
    public function __construct($host = NULL, $uid = NULL, $pw = NULL, $db = NULL)
    {
        $this->HostName = $host;
        $this->UserID = $uid;
        $this->Password = $pw;
        $this->DBName = $db;

        //Connect to Database
        $this -> Con = mysqli_connect($host, $uid, $pw, $db);
        if(mysgli_connect_errno($this -> Con))
        {
            echo "Failed to connect to MySQL; " . mysqli_connect_error();
        }

    }
    //Destructor
    public function __destruct()
    {
        //Close connection
        mysqli_close($this -> Con);
    }
    public function DisplayMembers()
    {
            }
            function DisplayAbout()
    {
            }
            function DisplayRegistrationForm()
    {
        echo("<h2>Become a Club Member</h2>

        <form name='register' method='post' action=''>
            <table>
                <tbody>
                    <tr>
                        <td width='80px'>

                        <td width='300'>

                    </tr>
                    <tr>
                        <td>
                            <label>Last Name: </label>

                        <td>

                        <td>

                    </tr>
                    <tr>

                    </tr>
                    <tr>
                        <td colspan='2' style='text-align: center;'>

                        </td>
                    </tr>
                </tbody>
            </table>    
        </form>");
    }
            function ProcessRegistrationForm()
    {
            }
            private function Get_Members_From_DB()
    {
            }
            private function Get_Members_Interests_From_DB($MemberEmail)
    {
            }
            private function Get_Interests_Types_From_DB()
    {
            }
 }
 ?>

我一生都无法弄清楚在表单部分的操作部分中放置什么以便在ProcessRegistrationFunction()课堂内使用。所以基本上，DisplayRegistrationForm()在文件中调用index.phpa div，然后我希望它ProcessRegistrationFunction()在类中被处理。但是，我似乎无法弄清楚如何做到这一点。

您可以将表单数据发送到 index.php 本身，然后将任何数据发送到您的流程函数。实现这一点的最佳方法是更改​​表单以将数据收集为数组。

这里myFormArray将存储有关表单的所有信息

<input id='firstname' type='text' name='myFormArray[firstname]' value='' required/>

<input id='lastname' type='text' name='myFormArray[lastname]' value='' required/>

提交表单时，可以在 index.php 中访问此值

所以在你的 index.php

 if(isset($_POST["submit"]){
    $formData = $_POST["myFormArray"]; // dont forget to sanitize any post data
   //than you can call your class function and pass this data
   $class = new class();
   $class->ProcessRegistrationFunction($formData);
 }

您的 ProcessRegistrationFunction($data) 现在将以数组形式包含所有数据..

您可以对其进行迭代并获取各个值

注意：你的类中有很多语法错误..还有更好的方法来实现这个类..你应该始终避免在你的类中使用 html 代码..

在正确输入类型时，您可以避免不必要的错误

 'if(mysgli_connect_errno($this -> Con))'

它应该是

 'if(mysqli_connect_errno($this -> Con))'
