**此代碼使成功登錄的用戶可以被定向到student_profile.php頁面,但是我需要這個來檢查嘗試登錄的用戶的類型,並根據以將該成員發送到適當的位置。在DB中,我有一個叫做account的字段,它具有不同的成員類型;學生,房東和管理員,他們都有自己的網頁。 **如果else或開關的情況下從登錄頁面的不同位置爲不同的成員組
<?php
include ("connect.php");
if (isset($_POST["user_login"]) && isset ($_POST["user_pass"])){
// formatting field via reg replace to ensure email and password only conisists of letters and numbers preg_replace('#[^A-Za-z0-9]#i','',
$login_user = $_POST["user_login"];
$login_password = $_POST["user_pass"];
// password is encryted in DB (MD5) therefore user inputted password will not match encryted password in DB - we have to assign new var
$decrypted_password = md5($login_password);
// Query which finds user (if valid) from DB - Achieving authentication via username and password
$user_query = mysqli_query($connect, "SELECT * FROM users WHERE email = '$login_user' AND password = '$decrypted_password' AND closed = 'no' LIMIT 1");
$check_user = mysqli_num_rows($user_query); // checking to see if there is infact a user which those credentials in the DB
if ($check_user==1){
while ($row = mysqli_fetch_array($user_query)){
$id = $row['user_id'];
}
// if the user credentials are correct, log the user in:
$_SESSION["user_login"] = $login_user;
header("Location:profile_student.php"); // refresh page
exit;
}
else {
echo "<div class='wrong_login'>
<p> Email or password is incorrect, please try again. </p>
</div>";

感謝這就是偉大的@Ravinder雷迪 –
我想這一段代碼來顯示一個錯誤,如果用戶沒有輸入正確的電子郵件或密碼。它似乎工作,但現在不工作。 –
