Question

您好我的脚本有问题，它不会创建并以任何形式连接到我的数据库。这是我的代码：

<?php
$host="fdb4.biz.nf"
$username="1373217_users";
$passowrd="1234";
$db_name="1373217_users"; // Database name 
$tbl_name="members"; // Table name 

mysql_connect("$host", "$username", "$passowrd") or die("Database could not connect");
mysql_select_db("$db_name") or die("Database selected could not be found");
$sql="INSERT INTO `members` ('user') VALUES ('$_POST[username]')";

$username=$_POST['username'];
$password=$_POST['password'];

$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);

$sql="INSERT INTO `members` (`username`)  VALUES ('{$_POST['username']}')";


// Mysql_num_row is counting table row
$count=mysql_num_rows($result);

// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1){

// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword"); 
header("location:login_success.php");
}
else {
echo "Wrong Username or Password";
}
?>

这是login.php，它给我的错误是：

解析错误：语法错误，第4行/srv/disk11/1373217/www/tracklist.co.nf/login.php中的意外T_VARIABLE

有人可以告诉我为什么吗？感谢。

Answer 1

你遇到语法错误，你错过了在$ host语句之后添加分号

 $host="fdb4.biz.nf";

Answer 2

问题是你在user附近推了'（单引号），你忘记了;附近的$host="fdb4.biz.nf"

更改此

$sql="INSERT INTO `members` ('user') VALUES ('$_POST[username]')";

到

$sql="INSERT INTO `members` (`user`) VALUES ('$_POST[username]')";

MySQL不会连接到数据库，nighter创建用户名和密码
