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 'group, year, active, password) VALUES ('Smith S. Ana Joy', 'ana' at line 1

an example or the variables that i am adding:

$name = Smith
$email = ana.smith
$group = A1
$year = I
$active = 1
$pass = a

Answer 1

GROUP is a reserved word in mySQL.

Wrap it in backticks:

`group`

or use a different column name.

Also make sure your code is protected against SQL injection (ie each variable is being sanitized before being inserted into the code).

Answer 2

GROUP is a reserved word. You should quote that column name:

... mail, `group`, ...

Answer 3

group is a MYSQL-command and may not be used like that in a value. Escape the field like so:

"INSERT INTO accounts (name, mail, \\"group\\", year, active, password) VALUES ('$name', '$email', '$group', '$year', '1', '$pass')";

Answer 4

Group is a reserverd word in MySQL and therefore you must qoute it. You can read more about it here: http://dev.mysql.com/doc/refman/5.5/en/reserved-words.html

Answer 5

group是保留关键字，应将其括在反引号中。
