嘿可以annyone查看我的代碼並解釋? $ error = array()不存儲我的錯誤,並且 $ error [] ='錯誤的用戶名或密碼!';不工作。我需要在同一頁面顯示我的錯誤,因爲我有登錄腳本。
<?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!
所以,你所添加的錯誤消息的數組,語法正確。顯示您實際嘗試顯示錯誤消息的代碼。 –
順便說一句,在'};'最後一行失去';'。 –
我嘗試在窗體中顯示它,所以我必須做什麼? (不要生氣,即時通訊新手在PHP和設計:D) –
