一个关于insert的问题

[anshenghao]

$sql = "insert into internal_user (id,username,userpasswd,rootpath) values(" . $_POST

['id'] . "," . $_POST['username'] . "," . $_POST['userpasswd'] . "," . $_POST

['rootpath'] . ")";

mysql_query($sql);

为什么这句语句会不执行呢?
奇怪了~ 有高手能告诉我吗?

.....
首先
insert into tab_name (col_names...) values (col_values)
对于字符型要加单引号
"insert into internal_user (id,username,userpasswd,rootpath) values ('','','','')";

然后你再把变量带进来。一步步来，学会找问题原因。
