Question

好吧，我收到了这个错误：

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 'desc,fb_title,fb_pic,fb_url,fb_desc) VALUES('', '', '', '', '', '', '', ''' at line 1

以下代码：

$sql="INSERT INTO page(title,css,favicon,charset,keywords,author,desc,fb_title,fb_pic,fb_url,fb_desc)
VALUES('$title', '$css', '$favicon', '$charset', '$keywords', '$author', '$desc', '$fb_title', '$fb_pic', '$fb_url', '$fb_desc')";

一切看起来都很好......怎么了？

Answer 1

DESC是保留关键字。你应该把它作为`DESC`来逃避它。

INSERT INTO page(title,css,favicon,charset,keywords,author,`desc`,fb_title,fb_pic,fb_url,fb_desc)
  VALUES('$title', '$css', '$favicon', '$charset', '$keywords', '$author', '$desc', '$fb_title', '$fb_pic', '$fb_url', '$fb_desc')

Answer 2

DESC 是一个保留关键字，您不能使用反引号操作符将其作为其他方式包围它。

下面..

$sql="INSERT INTO page(title,css,favicon,charset,keywords,author,desc,fb_t
                                                     ------------^

^{免责声明：不推荐使用mysql_ *函数，因为它们已被弃用。改为使用MySQLi或PDO。}

Answer 3

在desc附近添加反引号，因为它是一个保留字

INSERT INTO page(title,css,favicon,charset,keywords,author,`desc`,fb_title,fb_pic,fb_url,fb_desc)
VALUES('$title', '$css', '$favicon', '$charset', '$keywords', '$author', '$desc', '$fb_title', '$fb_pic', '$fb_url', '$fb_desc')

Answer 4

desc是mysql的保留关键字

$sql="INSERT INTO page(`title`, `css`, `favicon`, `charset`, `keywords`, `author`,`desc`,`fb_title`,`fb_pic`,`fb_url`,`fb_desc`)
VALUES('$title', '$css', '$favicon', '$charset', '$keywords', '$author', '$desc', '$fb_title', '$fb_pic', '$fb_url', '$fb_desc')";
