登錄和注冊php程序

Question

我想知道將代碼放置在什么位置/我的checkLogin.php，以便在單擊“注冊”時將其帶到注冊表單。 我不確定應該在哪里放置代碼或應該使用什么命令制作代碼，以便單擊注冊按鈕時，它不會告訴我我沒有填寫用戶名或密碼。

checkLogin.php：

<?php
/* connection info */
ini_set("display_errors","on");
error_reporting(E_ALL | E_STRICT);
ini_set("include_path","../../includes");
include("dbinfo.inc");
$cxn = mysqli_connect($host,$user,$password,$dbname) 
    or die("Couldn't connect to server.");

?>

/*  Program name: checkLogin.php

 *  all the form fields for blank fields.

Answer 1

嘗試將整個登錄或注冊系統寫入一個文件，或者最好將其寫入命名空間：

namespace myfile;
class Membership {
     public function exists() { returns true/false; }
     public function signup() { returns true/false; }
     public function signin() { returns true/false; }
}

並通過以下方式連接到您的名稱空間：

require 'membership.php';
use Membership as ms;
$obj = new ms\membership ();
$obj->signup(array('username'=>'' ,'password' => ''));

並與您的庫一起使用，而不是分離。

Answer 2

我要在這里暗中刺傷，但是您有注冊按鈕，我們假裝它看起來像這樣：

<a href="mylogin.php?register">Register</a>

請參閱如何將?register部分添加到URL？

然后，您可以執行以下操作：

include isset($_GET['register']) ? "register.inc" : "login.inc";
