php-表单未保存到数据库

2019-10-11 05:24:48  阅读:72  来源: 互联网

标签:php mysql forms



我制作了一个5K运行表单,其中用户输入有关他/她的基本信息(名字,姓氏,电子邮件,组织,是否参加活动,以及在查看豁免表单后选中一个复选框.

我在最后放置了一个提交按钮.我无法将表单连接到数据库.我已经尝试进行连接,并在mySql中创建了一个名为“ basicInfo”的表,这对编码来说是新手,因此,我感谢所能获得的所有帮助,并且坚持使用它.

到目前为止,这是我的代码

这是针对submitted.php(下一页)

<html>
    <head><title>Your form has been submitted</title></head>
    <body>
    <h1>See you at the 5K Run/walk for Memo.</h1>
    <p class="content">Your form has been submitted.</p>

    <p class="content">Click <a href="index.php">here</a> to go back to the main page.</p>
    </body>
</html>

解决方法:

基本上有两种使用表单将数据发送到数据库的方法.第一种方法是让人们填写表格并将数据发送到下一页.您可以添加Java脚本来检查填写的数据是否满足您的要求并立即做出响应.例如.是否已填写所有必填字段.下一页将处理数据并将其发送到MySQL服务器.您可以使用的表单方法是POST / GET.第二种方法是在一个页面上显示表单,并在同一页面上处理数据(PHP_SELF或通过在表单操作中引用同一页面).第二种方法要求代码非常结构化.如果需要检查数据是否已提交.接下来,您需要验证是否有效.如果表单已提交且输入有效,则数据将提交到数据库,并向访问者显示“谢谢您提交表单.我们将尽快与您联系”之类的文本.如果提交了表单并且数据无效,则访问者应停留在同一页面上,并显示错误消息,例如“以下字段需要填写:….”,并显示表单.如果未提交表单(第一次访问),则访问者应获得显示的表单.

最容易设置的方法是第一种方法,第二种是我认为最好的方法,但是我建议您从第一种方法开始.第一种方法运行后,您可以添加Javascript和/或将其更改为第二种方法.

表结构:

  `name` varchar(100) DEFAULT NULL,
  PRIMARY KEY (id_organisations)
) ENGINE=InnoDB;


CREATE TABLE IF NOT EXISTS basicinfo (

  `time` datetime NOT NULL,
  PRIMARY KEY (id)
) ENGINE=InnoDB;

SQL FIDDLE

重要的是要注意,这仅仅是一个开始.我没有测试过,因此请记住这一点.我不理解您的代码的某些部分,所以我不得不做一些猜测工作.

编辑:删除旧数据库并导入结构和数据:

DROP TABLE IF EXISTS basicinfo;
DROP TABLE IF EXISTS organisations;


CREATE TABLE organisations (
      id_organisations int(11) NOT NULL AUTO_INCREMENT,
      `name` varchar(100) DEFAULT NULL,
      PRIMARY KEY (id_organisations)
    ) ENGINE=MyISAM DEFAULT CHARSET=latin1;


CREATE TABLE basicinfo (
  id int(11) NOT NULL AUTO_INCREMENT,
  firstname varchar(30) NOT NULL,
  lastname varchar(50) NOT NULL,
  org int(11) NOT NULL,
  email varchar(100) NOT NULL,
  attendant int(11) NOT NULL,
  `time` datetime NOT NULL,
  PRIMARY KEY (id)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;


INSERT INTO `organisations` (`id_organisations`, `name`) VALUES
(1, 'Northeastern Illinois'),
(2, 'Illinois Institute of Technology'),
(3, 'Loyola'),
(4, 'Oberlin'),
(5, 'Northwestern'),
(6, 'Purdue'),
(7, 'IVSU'),
(8, 'UW-Madison'),
(9, 'UIllinois'),
(10, 'Iowa State University'),
(11, 'Michigan-Ann Arbor'),
(12, 'Marquette University'),
(13, 'Michigan State'),
(14, 'UIC'),
(15, 'Notre Dame'),
(16, 'VSAM'),
(17, 'Ohio State'),
(18, 'UCincinnati'),
(19, 'Northern Illinois'),
(20, 'Indiana-Bloomington'),
(21, 'University of Iowa'),
(22, 'St. Cloud');

如果之前已将UID更改为PHP代码中的ID.上面的查询将删除您的表(basicinfo),然后重新创建两个新表(basicinfo和组织).这就是将其应用于自己的数据库的方式.将上面的SQL代码复制到phpmyadmin.登录到phpmyadmin->选择您的数据库-> SQL->删除默认文本,然后将上面的代码复制到窗口中->运行查询(开始).

如果只想更改数据库,则可以使用以下查询:

ALTER TABLE `basicinfo` 
CHANGE `uid` `id` INT auto_increment,
CHANGE `firstname` `firstname` varchar(30),
CHANGE `lastname` `lastname` varchar(50),
CHANGE `org` `org` INT,
CHANGE `email` `email` VARCHAR(100), 
ADD `time` datetime NOT NULL;

但是您仍然需要创建并填充组织数据库.

CREATE TABLE organisations (
      id_organisations int(11) NOT NULL AUTO_INCREMENT,
      `name` varchar(100) DEFAULT NULL,
      PRIMARY KEY (id_organisations)
    ) ENGINE=MyISAM DEFAULT CHARSET=latin1;

INSERT INTO `organisations` (`id_organisations`, `name`) VALUES
(1, 'Northeastern Illinois'),
(2, 'Illinois Institute of Technology'),
(3, 'Loyola'),
(4, 'Oberlin'),
(5, 'Northwestern'),
(6, 'Purdue'),
(7, 'IVSU'),
(8, 'UW-Madison'),
(9, 'UIllinois'),
(10, 'Iowa State University'),
(11, 'Michigan-Ann Arbor'),
(12, 'Marquette University'),
(13, 'Michigan State'),
(14, 'UIC'),
(15, 'Notre Dame'),
(16, 'VSAM'),
(17, 'Ohio State'),
(18, 'UCincinnati'),
(19, 'Northern Illinois'),
(20, 'Indiana-Bloomington'),
(21, 'University of Iowa'),
(22, 'St. Cloud');
