<?php
$host="localhost"; // Host name
$username="cody2000"; // username
$password="115cody"; // password
$db_name="cody2000_aspire"; // Database name
$tbl_name="Users"; // Table name

    // Replace database connect functions depending on database you are using.
mysql_connect("$host", "$username", "$password");
mysql_select_db("$db_name");

// username and password sent from form
//NEVER Remove the mysql_real_escape_string. Else there could be an Sql-Injection!
$myusername=mysql_real_escape_string($_POST['loginuser']);
$mypassword=mysql_real_escape_string($_POST['loginpass']);

 $result=mysql_query($sql);

 mysql_fetch_assoc(mysql_query("SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'"

 $count=mysql_num_rows($result);

 if($count==1){
 // Register $myusername, $mypassword and redirect to file "login_success.php"
 session_register("myusername");
 session_register("mypassword");
 header("location:menu.php");
 } else {
 echo "Wrong Username or Password. Try again";
 }
 ?>

它说我的密码不正确。请帮助我是这方面的初学者。我有一堆代码混合在一起,我不知道哪个是正确的

从代码中删除以下行

$result=mysql_query($sql);

配置以下行

$result = mysql_query("SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'") or die(mysql_error());

 $count = mysql_num_rows($result);

if($count == 1) {
 // Your Code
 $users = mysql_fetch_assoc($result);
 session_register($users['username']);
} else {

}
