嘿,有人能查看我的代码并解释吗$error=array()不存储我的错误和 $error[]=“错误的用户名或密码!”;不工作。我需要显示我的错误在同一页,因为我有登录脚本

  <?php


$host="localhost"; // Host name
$username="root"; // Mysql username
$password=""; // Mysql password
$db_name="2"; // Database name

// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
if (isset($_POST['formsubmitted'])) {
    $error = array();//Declare An Array to store any error message 
};  
// username and password sent from form
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];

// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);

$sql="SELECT * FROM `members` WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);

// 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"
//store data:
$_SESSION['$myusername'];
$_SESSION['$mypassword']; 
//next page:

header("location:login_success.php");
}
else {
 $error[] = 'Wrong username or password!';

ty!

泰!
试试这个:

<?php
if(isset($error) && is_array($error))
{
   echo "<div class='error'>" . implode("<br />", $error) . "</div>";
}
蒂迈克尔!我明白了D 应该是这样的:

  <?php  echo '<div class="errormsgbox"> <ol>';
            foreach ($error as $key => $values) {

                echo '  <li>'.$values.'</li>';



            }

?>


因此,您已将错误消息添加到数组中,并且语法正确。显示您实际尝试显示错误消息的代码。丢失
}在你的最后一行。我试着以表格的形式显示它,所以我要做什么?(不要生气,我是php和design的新手:D)请按照我的要求发布代码。这就像在阵列上循环并显示每条消息一样简单。非常感谢您我得到了解决方案!:)
