爲什麼我在我的php代碼中出現「意外的$結束」？

我不知道我做錯了什麼。我一直在尋找其他論壇，說我的問題可能與沒有關閉花括號關閉或簡短的PHP標記<? ...有關。據我所知，我沒有這些。這是一個表單，可讓您知道是否有任何字段留空。

<?php 

if (count($_POST) > 0) 
{ 

    function check_if_field_submitted($field_to_check) 
    { 
     if (isset($_POST[$field_to_check]) && $_POST[$field_to_check] != '') 
     { 
      return TRUE; 
     } 
     else 
     { 
      return "YOU MUST FILL IN THE $field_to_check FIELD!"; 
     } 
    } 

    //-------------------------------------------------------- 

    $error_messages = array(); 

    //Validate the input 

    //Trim the fields 
    $_POST['first_name'] = trim($_POST['first_name']); 
    $_POST['last_name'] = trim($_POST['last_name']); 
    $_POST['comments'] = trim($_POST['comments']); 
    $_POST['first_name'] = strip_tags($_POST['first_name']); 
    $_POST['last_name'] = strip_tags($_POST['last_name']); 
    $_POST['comments'] = strip_tags($_POST['comments']); 

    //Required fields: 

    if (check_if_field_submitted('first_name') !== TRUE) 
    { 
     $error_messages[] = check_if_field_submitted('first_name'); 
    } 

    if (check_if_field_submitted('last_name') !== TRUE) 
    { 
     $error_messages[] = check_if_field_submitted('last_name');  
    } 

    if (check_if_field_submitted('hobbies') !== TRUE) 
    { 
     $error_messages[] = check_if_field_submitted('hobbies'); 
    } 

    if (check_if_field_submitted('university') !== TRUE) 
    { 
     $error_messages[] = check_if_field_submitted('university'); 
    } 

    if (check_if_field_submitted('year') !== TRUE) 
    { 
     $error_messages[] = check_if_field_submitted('year'); 
    } 

    if (check_if_field_submitted('comments') !== TRUE) 
    { 
     $error_messages[] = check_if_field_submitted('comments'); 

    if (count($error_messages) < 1) 
    { 
     header("Location: success.php"); 
    } 
}

首先，您使用的是標記html的兩倍，如您所見：此外，您可以在第一個函數中定義一個函數，如果它不太適合編寫清晰的代碼。 –

我正在計算11「{」和只有10「}」，所以是一個捲曲{不關閉... – danii

你應該檢查出Notepad ++，它具有諸如匹配大括號突出顯示等功能。 –

它看起來像你在你的if語句的一個缺少一個右括號。

我想你想改變這些行：

 if (check_if_field_submitted('comments') !== TRUE) 
     { 
      $error_messages[] = check_if_field_submitted('comments');

這樣：

 if (check_if_field_submitted('comments') !== TRUE) 
     { 
      $error_messages[] = check_if_field_submitted('comments'); 
     }

問題：

if (check_if_field_submitted('comments') !== TRUE) 
     { 
      $error_messages[] = check_if_field_submitted('comments'); 




if (count($error_messages) < 1) 
    { 

     header("Location: success.php"); 
    } 

}

答：

if (check_if_field_submitted('comments') !== TRUE) 
      { 
       $error_messages[] = check_if_field_submitted('comments'); 

      } 


    if (count($error_messages) < 1) 
     { 

      header("Location: success.php"); 
     } 

    }

如果我是你，我會找到一個支架匹配/突出顯示的IDE。

對IDE進行括號匹配 – danii
