在MySQL数据库中为新闻通讯添加三个新字段

[英]Adding three new fields in MySQL database for newsletter

 原文  2015-04-17 15:25:11  4   3    php/ html/ mysql/ ajax/ newsletter

问题描述

我具有有关PHP和MySQL的基本知识，但知识不足，无法从头开始创建新闻通讯。

我在Git Hub上找到了我喜欢的新闻通讯教程，并且希望通过一些小的改动在我的网站中实现该新闻通讯。

我在HTML代码中添加了三个额外的字段（全名，电话号码和URL）

当有人订阅时事通讯时，我想将这三个字段添加到MySQL数据库中。 目前，MySQL数据库中仅显示注册ID，电子邮件和注册日期。

如果有人可以帮助我在MySQL数据库中添加三个新字段，我将不胜感激。 一直试图使时事通讯工作几个小时而没有任何运气。

这里有很多问题：

SEND.PHP（缺少url参数） 

<?php
require 'inc/Database.class.php';
require 'inc/Newsletter.class.php';

if (!empty($_POST)) {
  $name= $_POST['full-name'];
  $email = $_POST['signup-email'];
  $phone = $_POST['phone-number'];
  $url = $_POST['website-url'];

  Newsletter::register($email, $name, $phone, $url);
}

NEWSLETTER.CLASS.PHP（将参数添加到register方法中并使用USE THEM） 

public static function register($p_email, $p_name, $p_phone, $p_url) {
       self::$email    = $p_email;
       self::$datetime = date('Y-m-d H:i:s');
       self::$name     = $p_name;
       self::$phone   = $p_phone;
       self::$url      = $p_url;

CREATE_TABLE.SQL添加这些列 

 CREATE TABLE `signups` (
   `signups_id` int(10) NOT NULL AUTO_INCREMENT,
   `signup_email_address` varchar(250) DEFAULT NULL,
   `signup_date` datetime DEFAULT NULL,
   `signup_url` varchar(250) DEFAULT NULL,
   `signup_name` varchar(100) DEFAULT NULL,
   `signup_phone` varchar(20) DEFAULT NULL,
    PRIMARY KEY (`signups_id`)
  ) ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

然后将它们添加到您的sql插入中： 

    $sql = "INSERT INTO signups (signup_email_address, signup_date, signup_url, signup_name, signup_phone) VALUES (:email, :datetime, :url, :name, :phone)";
    $q = $pdo->prepare($sql);
    $q->execute(
                    array(':email' => self::$email, ':datetime' => self::$datetime), ':url' => self::$url, ':name' => self::$name, ':phone' => self::$phone);

这很简单。 首先，您的Create_table查询将如下所示 

CREATE TABLE `signups` (

signups_id int（10）非空AUTO_INCREMENT， signup_email_address varchar（250）DEFAULT空， signup_date datetime DEFAULT空，full_name varchar（100）非空，phone_number整数（20）非空，主键（ signups_id ））ENGINE = MyISAM默认字符集= utf8;

在第二步中，检查电话号码，注册电子邮件和全名是否不能为空。 

        self::$full_name= $_POST['full-name'];
        self::$PhoneNo= $_POST['phone-no'];

在第三步中，在您的插入查询中进行这些更改

$ sql =“插入注册（signup_email_address，signup_date，full_name，phone_number）VALUES（：email，：datetime，：full_name，：phoneNo）”；

希望你有主意

在SEND.php中，您将发送三个参数，但在NEWSLETTER.CLASS.PHP中则不接收 

Newsletter::register($email, $text, $number); SEND.php

public static function register($email) { // NEWSLETTER.CLASS.PHP

更改为 

public static function register($email, $text, $number) { // NEWSLETTER.CLASS.PHP

然后您需要优化查询， 

if (!$data_exists) {
            $sql = "INSERT INTO signups (signup_email_address, signup_date, db_field_name, db_field_email,db_field_number) VALUES (:email, :datetime, :any_variable_for_name, :any_variable_for_email, :any_variable_for_number)";
            $q = $pdo->prepare($sql);

            $q->execute(
                array(':email' => self::$email, ':datetime' => self::$datetime, ':any_variable_for_name' => $name, ':any_variable_for_email' => $email, ':any_variable_for_number' => $number));

            if ($q) {
                $status  = "success";
                $message = "You have been successfully subscribed";
            } else {
                $status  = "error";
                $message = "An error occurred, please try again";
            }
        } else {
            $status  = "error";
            $message = "This email is already subscribed";
        }

这可能会对您有所帮助。
