如何添加動作標籤以形成？

我有一個工作的PHP留言腳本。它只有1個文件。我試圖證明它，只有一個錯誤：如何添加動作標籤以形成？

Line 147, Column 36: required attribute "action" not specified 
<form method="post" name="blogform">

現在的代碼是這樣的，我相信我會需要將文件拆分兩個，這樣我可以爲行動標籤創建一個文件但我只是不知道如何。任何幫助深表感謝。

if(isset($_SESSION["ellenorzo"]) && !empty($_SESSION["ellenorzo"]) && $_SESSION["ellenorzo"]==$_POST["code"]){  

    $name = trim($_POST['name']); //eliminating whitespaces 
    $email = trim($_POST['email']); 
    $message = addslashes(trim($_POST['message'])); 

    $query = "INSERT INTO blog (name, email, message, date) " . 
      "VALUES ('$name', '$email', '$message', NOW())";

action屬性指定表單發送到的鏈接。如果調用的形式本身，你可以讓它空白：

<form action="" method="post" name="blogform">

確保POST是W3標準中定義的所有上限也是一個好主意......我注意到，如果情況並非如此，Firefox可能會有問題。（最好是安全而不是遺憾） – silvster27 2013-01-03 19:41:47

的action標籤告知形式，其中提交數據。如果它留空，它會嘗試將數據提交到當前的php頁面。如果它給你帶來麻煩，也許你需要指定它並將它指向生成表單的php頁面。

在您提供的代碼中，處理新插入的代碼位於此頁面的頂部，因此您應該將action標記設置爲頁面的名稱。

順便說一下，你應該確保你的輸入全部清除;在插入它們之前使用trim()正在尋求麻煩。有關此主題的更多信息，請參閱here。
