Form Submission - Using a function within a PHP cl

问题:

I am using three files on a project: index.php, class.php, and styles.css.

All my functions reside within a php class in the class.php file:

<?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'>
                            <label>First Name: </label>

                        <td width='300'>

                    </tr>
                    <tr>
                        <td>
                            <label>Last Name: </label>
                        </td>
                        <td>
                            <input id='lastname' type='text' name='lastname' value='' required/>
                        </td>
                    </tr>
                    <tr>

                        </td>
                        <td>
                            <input id='email' type='text' name='email' value='' required/>
                        </td>
                    </tr>
                    <tr>
                        <td>
                            <label>Gender: </label>
                        </td>
                        <td>

                    </tr>
                    <tr>
                        <td>
                            <label>Interested in: </label>
                        </td>
                        <td id='check'>

                        </td>
                    </tr>
                    <tr>
                        <td colspan='2' style='text-align: center;'>
                            <input id='submit' type='submit' name='submit' value='Sign Up'/>
                        </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()
    {
            }
 }
 ?>

I cannot for the life of me figure out what to put in the action section of the form portion in order to use the ProcessRegistrationFunction() within the class. So basically, the DisplayRegistrationForm() is called in the index.php file in a div, and then I want it to be processed by the ProcessRegistrationFunction() within the class. However, I cannot seem to figure out how to do this.

回答1:

you can send your form data to index.php itself and than send whatever data to your process function. the best way to implement this will be is to change your form to collect data as an array.

here myFormArray will store all the information about the form

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

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

this value can be accessed in your index.php when you submit the form

so in your 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);
 }

your ProcessRegistrationFunction($data) will now have all the data in an array form..

you can iterate over it and fet the individual values

Note: there are lot of syntax error in your class.. also there is better way to implement this class.. for one you should always avoid html code inside your classs..

回答2:

while typing type correctly so u can avoid unwanted errors

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

it should be

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