php和MySQL初学者接受用户输入、修改数据库和返回值
在回答这个问题之前，我要说的是，我只有六周的PHP经验和两周的MySQL经验。我试图创建一个演示网站，将接受用户输入的软件错误。表单接受用户输入，通过使用PHP，我连接到我建立的本地SQL数据库。数据库Bug已经建立，bugDetails表也已经建立，包括版本、硬件、操作系统和描述字段。我构建了一个PHP文档来概述表单并将信息传递给SQL数据库。我还创建了两个include文件来保护数据库密码，并解决了magic quotes问题。就我的一生而言，我无法让代码工作，我不确定为什么。非常感谢您的帮助。这是我的密码： bugs.phpphp和MySQL初学者接受用户输入、修改数据库和返回值,php,html,mysql,sql,forms,Php,Html,Mysql,Sql,Forms,在回答这个问题之前，我要说的是，我只有六周的PHP经验和两周的MySQL经验。我试图创建一个演示网站，将接受用户输入的软件错误。表单接受用户输入，通过使用PHP，我连接到我建立的本地SQL数据库。数据库Bug已经建立，bugDetails表也已经建立，包括版本、硬件、操作系统和描述字段。我构建了一个PHP文档来概述表单并将信息传递给SQL数据库。我还创建了两个include文件来保护数据库密码，并解决了magic quotes问题。就我的一生而言，我无法让代码工作，我不确定为什么。非常感谢您的帮

在您的bugs.php中，您的php不完整。您没有用；关闭$sql的分配；。SQL的插入语法不正确：
您缺少分号；在sql语句中，请将当前sql语句$sql=INSERT INTO BUG DETAILS SET version=$version'，hardware='$hardware'，os=$os，description='$description'，更改为$sql=INSERT INTO BUG DETAILS SET version=$version'，hardware='$hardware'，os=$os，description='$description'；用分号代替逗号
谢谢您的插入查询具有更新语法。它也不完整，并显示语法错误。这是我能看到的第一件事。
