表單驗證顯示字段未完成

我正在爲使用PHP和MySQL的自己開發一個小項目。表單驗證顯示字段未完成

我已經創建了一個註冊表單，我一直在填寫它來測試它的工作原理。我在表單中添加了驗證來檢查是否有空字段，但即使我將數據輸入到每個字段中，它也會返回一個警告，說明並非所有字段都填充了，當它們顯然是。

下面是我的代碼：

<?php ob_start(); ?> 
<?php require_once ("php/init.php"); ?> 
<?php 
    $user = new User(); 
if (isset($_POST['submit'])) 
{ 
    $user_username = trim($_POST['username']); 
    $user_email = trim($_POST['email']); 
    $user_firstname = trim($_POST['firstName']); 
    $user_lastname = trim($_POST['lastName']); 
    $user_password = trim($_POST['password']); 
    $verifyPassword = trim($_POST['passwordV']); 
    $user_company = trim($_POST['company']); 

    $validEmail = preg_match('/^[A-z0-9_\-]+[@][A-z0-9_\-]+([.][A-z0-9_\-]+)+[A-z.]{2,4}$/', $user_email); 

    if ($user_username == "" 
     or $user_email == "" 
     or $user_firstname == "" 
     or $user_lastname == "" 
     or $user_password == "" 
     or $verifyPassword == "" 
     or $user_company == "" 
    ) 
    { 
     $message = "You have not completed all the required fields, please try again."; 
     echo "<script type='text/javascript'>alert('$message');</script>"; 
    } 
    else 
    { 
     if ($validEmail) 
     { 
      if ($_POST['password'] != $_POST['passwordV']) 
      { 
       $message = "The passwords that you entered do not match, please try again."; 
       echo "<script type='text/javascript'>alert('$message');</script>"; 
      } 
      else 
      { 
       $userFound = User::locate($user_username); 

       if ($userFound) 
       { 
        $message = "The username entered is already being used, please Login or enter a username."; 
        echo "<script type='text/javascript'>alert('$message');</script>"; 
       } 
       else 
       { 
        $user_password = User::hash($user_password); 

        $user->user_username = $user_username; 
        $user->user_email = $user_email; 
        $user->user_firstname = $user_firstname; 
        $user->user_lastname = $user_lastname; 
        $user->user_password = $user_password; 
        $user->user_company= $user_company; 

        $user->insertUser(); 

        redirect("wait.php"); 
       } 
      } 
     } 
     else 
     { 
      $message = "The email address that was entered is not in the correct format"; 
      echo "<script type='text/javascript'>alert('$message');</script>"; 
     } 
    } 
} 
else 
{ 
    $user_username = ""; 
    $user_email = ""; 
    $user_firstname = ""; 
    $user_lastname = ""; 
    $user_password = ""; 
    $verifyPassword = ""; 
    $user_company = ""; 
} 

if (isset($_POST['back'])) 
{ 
    redirect('index.php'); 
} 
?>

        </form> 
       </li> 
      </div> 
     </div> 
    </body> 
</html>

任何幫助，因爲我有點卡住將不勝感激。

不跳出來...你可以'var_dump'那個'if'阻止你檢查空嗎？很顯然，其中的一個是空的......不要相信$ _POST的轉儲......看看你的代碼正在評估什麼。 – ficuscr

<input type="text" name="Company">注意大寫'C'。該代碼雖然尋找'公司'。

var_dump是你的朋友！

我建議你在寫變量等方面變得非常一致。就個人而言，我還會考慮縮減代碼樣式。但至少在命名事物時一定非常嚴格。

感謝您提供有效的信息。也感謝你對我的代碼的建議，我對此仍然相當陌生。 –

檢查$ _POST字段的名稱，如果在形式上與此相同:)。
