【中文标题】PHP, Html5, xampp【英文标题】：Php, Html5, xampp 【发布时间】：2018-08-26 22:10:19 【问题描述】：我正在尝试执行我在 XAMPP 中拥有的这个 php 文件。我正在尝试通过表单将数据更新到数据库，当我输入信息并提供提交按钮时，页面刚刚重新加载，或者我收到消息尽管我填写了所有字段，但所有字段都是必需的。对代码进行检查。我输入的数据只是没有更新到数据库中。我已经检查了数据库名称和表名称，如果我正确提及它，并且我尝试检查我是否能够连接到数据库。在这种情况下，它会正确连接到数据库。但只是没有更新表中的信息。

【问题讨论】：
【参考方案1】：您的某些输入标签名称有空格，例如 name="bg" 而不是 name="bg"。输入的情况相同 - add1 和 add2。
更新了下面的代码。它应该可以正常工作。

【参考方案2】：作为最后一个答案，删除 (blood group : name="bg", address1: name="add1", address2: name="add2") 一些输入标签名称中的空格。

此代码复制并粘贴。
当您使用 isset 功能时，请使用帖子的值来完善状态，例如
if(isset($_POST["submit"]) == "submit")
如果您在一页中有很多按钮，那将非常有帮助，非常感谢。
【讨论】：
【参考方案3】：可以用两种方式编写 INSERT INTO 语句。
第一种方式同时指定列名和要插入的值：
第 1 步：
INSERT INTO table_name (column1, column2, column3, ...) VALUES (value1, value2, value3, ...);
如果要为表的所有列添加值，则无需在 SQL 查询中指定列名。但是，请确保值的顺序与表中列的顺序相同。 INSERT INTO 语法如下：
第 2 步：
INSERT INTO table_name VALUES (value1, value2, value3, ...);
在您的代码中，我想您正在尝试使用第二种方法，但您没有使用所有列。 （例如 id 列可能是自动递增的）
所以改变你的这个插入代码
INSERT INTO donor VALUES('$name','$lname','$city','$district','$state','$Phone','$p1','$pincode','$bg','$add1','$add2');
到 第 1 步，如上所示，如下所示。
INSERT INTO donor (name, lname, city, district, state, phone, p1, pincode, bg, add1, add2) VALUES('$name','$lname','$city','$district','$state','$Phone','$p1','$pincode','$bg','$add1','$add2');
