我的php需要一些帮助+；基于mysql的表单
我已经在这个基于PHP的表单上工作了一段时间，它基本上是一个注册表单，我想把表单中的细节放到一个MySQL数据库中（我已经构建了这个数据库）。麻烦的是，似乎没有任何值被插入到数据库的各个行中，我想知道是否有比我更有经验的人可以浏览一下，让我知道是什么问题？提前谢谢 我将在这里显示表单本身的代码、数据库连接的include和MySQL代码（出于显而易见的原因，我更改了database.php include的真实用户详细信息）： 表单本身（将其放在“register.php”中，其中显示“//INSERT HTML FOR form HERE”我的php需要一些帮助+；基于mysql的表单,php,mysql,forms,Php,Mysql,Forms,我已经在这个基于PHP的表单上工作了一段时间，它基本上是一个注册表单，我想把表单中的细节放到一个MySQL数据库中（我已经构建了这个数据库）。麻烦的是，似乎没有任何值被插入到数据库的各个行中，我想知道是否有比我更有经验的人可以浏览一下，让我知道是什么问题？提前谢谢 我将在这里显示表单本身的代码、数据库连接的include和MySQL代码（出于显而易见的原因，我更改了database.php include的真实用户详细信息）： 表单本身（将其放在“register.php”中，其中显示“//IN
database.php谢谢大家的帮助…因此我已经修复了所描述的问题，现在更新了代码如下：由于将有问题的代码文件复制并粘贴回此处将使字符限制超过30000个，因此我已将文件上载到MediaFire.com 无论如何，在修复此代码后，我能够用一些数据填充表单并成功填充数据库（稍后将修复重复用户等问题）。此代码的缺陷在于，如果我在任何字段中未输入任何内容的情况下按下提交按钮，我仍然会收到一条消息，说“我的注册已成功”，我的数据库中会填充默认值，或者根本没有。我已在下面列出了这些详细信息：
- 用户id:1
- 用户电子邮件：空白
- user_pass：使用md5和sha组合的一些散列值 加密
- 用户\通过\确认：同上
- 用户\用户名：空
- 名字：空白
- 姓氏：空白
- 性别:男
- 生日：1日
- 出生日期/月份：1月
- 出生日期/年份：0
- 电话号码：0
- 手机号码：0
- 地址行1：空白
- 地址行1：空白
- 地址行1：空白
- 州：空白
- 邮政编码：0
- 最近的_镇：0
我应该看到我在php代码中为“registerprocessing.php”指定的错误消息，而不是插入任何内容。我想要的是，如果用户试图提交表单而不填写任何字段，错误警告将显示在“registerprocessing.php”上页面，然后用户可以返回表单并填写。可能我在检查错误或检查字段的非输入方面有问题，但我已经尝试并测试了一些版本，尝试修复所有问题，但没有任何效果。任何帮助都将不胜感激：）问题是：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，不要混淆数据库模式名和表名。只是为了澄清@Shivan的意思。“INSERT INTO tablename（colname，colname…..您已经将其插入到数据库名称中了（colname，colname…..大家好，在我的讲座（关于高级web开发）之后，我们将看到它是如何工作的）：”.谢谢你提醒我Shivan和bumperbox，我的眼睛在看了很多行代码后变得模糊，我往往会犯一些小错误，这些错误会层出不穷…所以我现在更新了“INSERT INTO tablename”语句…更新后，我尝试通过表单提交详细信息，并不断收到错误消息（这是我预先定义的）：“错误：注册帐户需要所有字段。”。我发现这很奇怪，因为我正在字段中输入输入。如果有人想要文件的压缩文件夹，请告诉我，我很乐意给他们发电子邮件……你可以将空（）函数分解为几个If语句（甚至可以将它们回显出来），这样您就可以知道哪个变量是空的。-0.35用于仍然使用
