PHP把数据写入数据库问题,能够连接,但是无法把数据写入数据库。

}
mysql_query($sql);
if($sql)

print_r($sql);

$sql="insert into liuyanben (id,name,from,email,qq,title,content,lastdate)"." values('','$_POST[user]','$_POST[from]','$_POST[email]','$_POST[qq]','$_POST[title]','$_POST[content]',now())";
这句话有点错误
$sql = "insert into liuyanben
(`id`,`name`,`from`,`email`,`qq`,`title`,`content`,`lastdate`)
values
('','".$_POST['user']."','".$_POST['from']."','".
$_POST['email']."','".$_POST['qq']."','".
$_POST['title']."','".$_POST['content']."'now())";
你把SQL这样修改一下 如果还是不行按照下面的方法测试
调试方法修改
include("bbs.php");
if($_POST['submit'])
{
$sql="insert into liuyanben (id,name,from,email,qq,title,content,lastdate)"." values('','$_POST[user]','$_POST[from]','$_POST[email]','$_POST[qq]','$_POST[title]','$_POST[content]',now())";
}
mysql_query($sql);
代码为
include("bbs.php");
if($_POST['submit'])
{
$sql="insert into liuyanben (id,name,from,email,qq,title,content,lastdate)"." values('','$_POST[user]','$_POST[from]','$_POST[email]','$_POST[qq]','$_POST[title]','$_POST[content]',now())";
}
var_dump($sql);
exit;
mysql_query($sql);
查看输出结果的sql字符串
使用 SQL工具(例如phpmyadmin)调试该字符串
对照调试结果修改
$sql="insert into liuyanben (id,name,from,email,qq,title,content,lastdate)"." values('','$_POST[user]','$_POST[from]','$_POST[email]','$_POST[qq]','$_POST[title]','$_POST[content]',now())";
