登錄功能與PHP的mysql錯誤

Question

我想創建一個登錄功能與PHP。

直到現在，這是我得到的。

<?php 
include("dbconnection.php"); 
//select a database to work with 
$mysqli->select_db("eamunter_opskrift"); 
Echo ("Selected the eamunter_opskrift database...<BR><BR>"); 
// get the username and password from the login form 
$username=$_POST['username']; 
$password=$_POST['password']; 

//Protect username and password 
$username = stripslashes($username); 
$password = stripslashes($password); 
$username = mysql_real_escape_string($username); 
$password = mysql_real_escape_string($password); 

$query ="SELECT * FROM brugerregistration WHERE username='$username' and password='$password'"; 
$result = $mysqli->query($query); 
$count=mysqli_num_rows($result); 
// If result matched $username and $password, the count of table rows should equal 1 
if($count==1){ 
// Register session variables and redirect the user to "login_success.php" page 
session_start(); 
$_SESSION['username']= $username; 
header("location:login_success.php"); 
} 
else { 
echo "Wrong Username or Password"; 
} 
?> 

我不斷收到同樣的錯誤 我想不出是什麼問題...我dbconnection.php工作的其他任何地方。

Selected the eamunter_opskrift database...

Wrong Username or Password 

任何人都可以幫我嗎？

如果重要我也可以上傳表格，但並不認爲它很重要。

Answer 1

更換mysql_real_escape_string與$mysqli->real_escape_string

（另外，你不需要stripslashes電話，real_escape_string應該做的一切，爲你）

Answer 2

您在混合使用mysql_*和mysqli_*函數。

應該

$username = $mysqli->real_escape_string($username); 
$password = $mysqli->real_escape_string($password); 

Answer 3

試試：

<?php 
    include("dbconnection.php"); 
    //select a database to work with 
    $mysqli->select_db("eamunter_opskrift"); 
    Echo ("Selected the eamunter_opskrift database...<BR><BR>"); 
    // get the username and password from the login form 
    $username=$_POST['username']; 
    $password=$_POST['password']; 

    //You should use your object and current connection 
    $username = $mysqli->real_escape_string($username); 
    $password = $mysqli->real_escape_string($password); 

    $query ="SELECT * FROM brugerregistration WHERE username='$username' and password='$password'"; 
    $result = $mysqli->query($query); 
    $count=mysqli_num_rows($result); 
    // If result matched $username and $password, the count of table rows should equal 1 
    if($count==1){ 
    // Register session variables and redirect the user to "login_success.php" page 
    session_start(); 
    $_SESSION['username']= $username; 
    header("location:login_success.php"); 
    } 
    else { 
    echo "Wrong Username or Password"; 
    } 
    ?> 

Answer 4

看到t他的mysql_real_escape_string

DOC替換：

$username = mysql_real_escape_string($username); 
$password = mysql_real_escape_string($password); 

由：

$username = $mysqli->real_escape_string($username); 
$password = $mysqli->real_escape_string($password);
