如何从帖子中抓取数据到班级 [英] How to grab data from post to a class

问题描述

如果我有一个表格，例如(不是所有的代码只有一个字段和我的输入):

<form id="registration" method="post" action="results.php"><label for="first_name">名字:</label><input type="text" id="first_name" name="first_name" maxlength="100" tabindex="1"/><input type="submit" id="login_submit" name="submit" value="Submit"/align="right"></表单>

是否可以从表单中获取数据，然后将该数据输出到另一个页面.我现在拥有的方式只是将帖子从表单回显到页面:

我不知道如何开始，但我希望帖子中的数据先去上课.因此，如果我创建一个名为registeredUser 的类，我将如何从表单中获取该数据?

解决方案

你好，我觉得你需要先了解一些OPP教程

你想要的例子

class RegisterUser {私人 $firstName;私人 $lastName;私人 $emailAddress;函数__构造(){$this->firstName = isset($_POST['first_name']) ?$_POST['first_name'] : null;$this->lastName = isset($_POST['last_name']) ?$_POST['last_name'] : null;$this->emailAddress = isset($_POST['email_address']) ?$_POST['email_address'] : null;}函数开始(){if (empty($this->firstName) || empty($this->lastName) || empty($this->emailAddress)) {throw new Exception("不允许空帖");}别的{//做一些 stuiffecho "注册完成";}}}$register = new RegisterUser();如果(！空($_POST)){$register->start();}

If I have a form such as (not all the code just one field and my input):

<div id="login_form">
<form id="registration" method="post" action="results.php">
<label for="first_name"> First Name: </label>
<input type="text" id="first_name" name="first_name" maxlength="100" tabindex="1" />

<input type="submit" id="login_submit" name="submit" value="Submit"/ align="right">

</form>
</div>

Is it possible to grab the data from the form and then output that data to another page. The way I have it now I am just echoing the post from a form to a page:

<?php

$first_name = $_POST['first_name'];
$last_name = $_POST['last_name'];
$email_address = $_POST['email_address'];


echo 'Hello ';
echo "{$first_name} {$last_name}";
echo '<br/>';
echo '<br/>';
echo 'We have your email address as: "';

echo "{$email_address}"; 
echo '"';


 ?> 

Im not sure how to get started but I would like the data from post to go to a class first. So if I create a class called registeredUser how would I grab that data from my form?

解决方案

Hello I think you need some tutorials on OPP first

Example of what you want

class RegisterUser {
    private $firstName;
    private $lastName;
    private $emailAddress;

    function __construct() {
        $this->firstName = isset($_POST['first_name']) ? $_POST['first_name'] : null;
        $this->lastName = isset($_POST['last_name']) ? $_POST['last_name'] : null;
        $this->emailAddress = isset($_POST['email_address']) ? $_POST['email_address'] : null;
    }

    function start() {
        if (empty($this->firstName) || empty($this->lastName) || empty($this->emailAddress)) {
            throw new Exception("Empty Post not allowed");
        }

        else
        {
            // Do some stuiff
            echo " Registration Done";
        }
    }
}

$register = new RegisterUser();
if(!empty($_POST))
{
    $register->start();
}
