註冊表格帶回登錄憑證

我已經在PHP中創建了一個用戶註冊表單，當我訪問該頁面時，表單的用戶名部分已經以我自己的登錄憑證填寫，並且與密碼相同。表單的其他部分也作爲未定義的索引填充。註冊表格帶回登錄憑證

下面顯示了我的註冊表單的表單和PHP代碼。表單本身實際上工作並填充到我的數據庫。

移除VALUE = 「」從每一個場 –

維基您好。我想要這些值，所以如果他們在表單提交時犯了錯誤，他們不必再次填寫所有值 – Stuart

如果您在該網站的瀏覽器中保存了密碼，它也可能顯示，在這種情況下，您必須使用jQuery或JavaScript刪除jQuery中的值： $（「＃idOfInput」）。val（「」）; –

初始化所有與空字符串變量。你的問題將得到解決，將解決。

<?php  
$username=""; 
    $password=""; 
    $forename=""; 
    $surname=""; 
    $email=""; 
    $telephone=""; 
    $address1=""; 
    $town=""; 
    $postcode=""; 
if(isset($_POST["submit"])){ 

     $username=$_POST['username']; 
     $password=$_POST['password']; 
     $forename=$_POST['forename']; 
     $surname=$_POST['surname']; 
     $email=$_POST['email']; 
     $telephone=$_POST['telephone']; 
............ 
.......... 
......
