Mysql从html表单插入错误

Question

我已经建立了一个名为jobs 的数据库，我正在尝试通过一个调用php 文件的html 表单将数据插入其中。提交表单后，我在控制台中看到以下错误。

错误：无法执行 INSERT INTO 作业（id、title、pay、description、location、max_people、people_going、tasks、start_time、end_time、start、end） 值（默认，'testTitle'，'4.00'，'testd'，'testl'，'4'，'1'，'testt'，'13:00:00'，'14:00:00'，'2016 -05-31 13:00:00'，'2016-05-31 14:00:00'）。

我可以通过 phpMyadmin 手动输入数据，只有当我尝试通过表单更新数据库时才会发生这种情况。我对使用数据库比较陌生，所以我相信这很简单。如果能提供任何帮助，我将不胜感激。

数据库布局如下，不能为空：

• id 类型：int，自动增量
• 标题类型：varchar
• 支付类型：十进制(15,2)
• 描述类型：文本
• 位置类型：文本
• max_people 类型：int
• people_going 类型：int
• 任务：文本
• start_time 类型：时间
• end_time 类型：时间
• 开始类型：日期时间
• 结束类型：日期时间

已解决

解决方案：代码实际上存在多个问题。在删除整数和小数周围的引号，以及将我的所有语句切换为使用 mysqli 之后；我收到了无法连接到数据库的错误。已通过在代码中添加 mysqli_connect 以及一些变量来解决此问题。

Answer 1

试试这个

$sql = "INSERT INTO jobs (`title`, `pay`, `description`, `location`, `max_people`, `people_going`, `tasks, `start_time, `end_time`, `start`, `end`) VALUES ('$job_title', '$job_pay', '$job_summary', '$job_location', '$job_people', '$j_going', '$job_tasks', '$job_start_time', '$job_end_time', '$event_start', '$event_end')";

start 和 end 是 MySQL 的保留字
