遇到鬼了,简单的数据库查询,显示Unknowncolumn'titletest'in'fieldlist'

时间:2021-07-01 10:21:17 帮助过:3人阅读

数据字段为:id(自增)、title(varchar(50)、content(longtext)
代码为
$title = $_POST['title']; (值为:titletest)
$content =$_POST['content'];(值为:contenttest )
$insert = "insert into article(title,content) values(".$title.','.$content.")";

错误为:Unknown column 'titletest' in 'field list'

代码为
$title = $_POST['title']; (值为:title test)这个和上面的多一个空格
$content =$_POST['content'];(值为:contenttest )
$insert = "insert into article(title,content) values(".$title.','.$content.")";

错误为:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'test,contenttest)' at line 1

将$insert = "insert into article(title,content) values(".$title.','.$content.")";
中的$title, $content 换成字符串就可以插入


回复讨论(解决方案)

语句有问题, 换成这样 $insert = "insert into article(title,content) values('$title','$content')";

sql串得有问题,试试这个 $insert = "insert into article(title,content) values('".$title."','".$content."')";

$insert = "insert into article (title,content) values(‘$title','$content’)";

语句有问题, 换成这样 $insert = "insert into article(title,content) values('$title','$content')";


谢谢,看来我还是太垃圾,这个简单的问题搞了1个多小时,是不是变量本身需要一个引号呢?
