不推荐使用：函数mysql（）已弃用   第39行/home/u624273934/public_html/ecommerce/admin_area/login.php

警告：mysql（）期望参数1是字符串，对象是给定的   第39行/home/u624273934/public_html/ecommerce/admin_area/login.php

警告：mysql_result（）需要至少2个参数，1中给出1   第41行/home/u624273934/public_html/ecommerce/admin_area/login.php

代码是这样的：

 <?php 
 session_start();

 ?>
 <!DOCTYPE>
 <html>
    <head>
        <title>Login Form</title>
 <link rel="stylesheet" href="styles/login_style.css" media="all" /> 

    </head>
 <body>
 <div class="login">
 <h2 style="color:white; text-align:center;"><?php echo @$_GET['not_admin']; ?></h2>

 <h2 style="color:white; text-align:center;"><?php echo @$_GET['logged_out']; ?></h2>

    <h1>Admin Login</h1>

 </body>
 </html>
 <?php 

 if(isset($_POST['login'])){

        $user_email = $_POST['user_email'];
        $user_pass = $_POST['user_pass'];

        $sel_c = "select * from admins where user_pass='$user_pass' AND user_email='$user_email'";

        $run_c = mysql($con, $sel_c);

        $check_customer = mysql_result($run_c); 

        if($check_customer==0){

        echo "<script>alert('Password or email is incorrect, plz try again!')</script>";
        exit();
        }
        $ip = getIp(); 

        $sel_cart = "select * from cart where ip_add='$ip'";

        $run_cart = mysqli_query($con, $sel_cart); 

        $check_cart = mysqli_num_rows($run_cart); 

        if($check_customer>0 AND $check_cart==0){

        $_SESSION['user_email']=$user_email; 

        echo "<script>alert('You logged in successfully, Thanks!')</script>";
        echo "<script>window.open('customer/my_account.php','_self')</script>";

您正在使用弃用的方法。不鼓励使用mySql_方法支持mysqli_方法。（注意i）

<强>替换

$run_c = mysql($con, $sel_c);
$check_customer = mysql_result($run_c);

。通过

$run_cart = mysqli_query($con, $sel_c); $rows = array(); while ($row = mysqli_fetch_assoc($run_cart)) { $rows[] = $row; }

您之后在脚本中使用了mysqli

$run_cart = mysqli_query($con, $sel_cart); $check_cart = mysqli_num_rows($run_cart);

我得到这个erorr，我试图解决它，但我不能.Deprecated：函数mysql（）
