需要一些基于我的php + mysql表单的帮助

标签： php mysql forms

现在已经在这个基于PHP的表单上工作了一段时间，基本上它是一个注册表单，我想将表单中的详细信息放入MySQL数据库（我已经构建）。麻烦是没有值似乎被插入到数据库中的各个行中，我想知道是否有比我更多经验的人可以浏览它并让我知道什么是错的？提前谢谢！

我将在这里显示表单本身的代码，数据库连接的包含以及MySQL代码（出于显而易见的原因，我已经更改了database.php包含的真实用户详细信息）：

表单本身（将其放在“register.php”中，表示“//在此处插入HTML格式”

感谢所有人的帮助...所以我已经修复了所描述的问题并且现在更新了代码，如下所示：由于复制和粘贴有问题的代码文件，因此需要超过30,000的字符数限制限制，我已将文件上传到MediaFire.com here。

无论如何，在修复此代码之后，我可以使用一些数据填写表单并成功填充我的数据库（稍后将修复诸如重复用户之类的内容）。这样做的缺点是，如果我按下提交按钮而不在任何字段中输入任何内容，我仍然会收到一条消息“我的注册已成功”，并且我的数据库将填充默认值或根本没有任何内容。我在下面列出了这些细节：

  • user_id：1
  • user_email：BLANK
  • user_pass：使用md5和sha的组合的一些散列值 加密
  • user_pass_confirm：与上述相同
  • user_username：BLANK
  • 名字：BLANK
  • 姓氏：BLANK
  • 性别：男
  • birthdate_day：1st
  • birthdate_month：January
  • birthdate_year：0
  • phoneNumber：0
  • mobileNumber：0
  • addressline1：BLANK
  • addressline1：BLANK
  • addressline1：BLANK
  • stateprovince：BLANK
  • 邮政编码：0
  • nearest_town：0

而不是插入任何内容，我应该看到我在php代码中为“registerprocessing.php”指定的错误消息。我想要的是，如果用户尝试提交表单而不填写任何字段本身，错误警告将显示在“registerprocessing.php”页面上，然后用户可以返回到表单并填写它。也许我如何检查错误或检查字段是否有输入有问题，但我已经尝试并测试了几个版本来尝试修复所有内容，但没有任何作用。任何帮助将不胜感激：）

1 个答案:

答案 0 :(得分：1)

问题是：您的SQL创建了一个名为“users”的表，但您正在将数据插入名为“loginsystem2”的表中。

另外，尽量不要在数据库模式名称和表名之间混淆。
