'; $ sql =「insert into useraccount（Firstname，Lastname，Username，email，Password）values（$ Firstname，$ Lastname，$ Username，$ Password，$ email）」;' 你有沒有試過這種方式？ –

+0

你在混合mysqli_ *和mysql_ *，添加php error_reporting，你也有語法錯誤'$ result = mysql_query（$ sql）'缺少分號 – devpro

+0

如果數據庫用戶名是正確的，這將工作'$ result = mysqli_query（$ con ，$ sql）;' – devpro

它是什麼？ '$ result = mysql_query（$ sql）' – devpro

-1

您的HTML有誤。您的types不對。請參閱HTML文檔：http://www.w3schools.com/tags/att_input_type.asp。

並且ID與POST Params不等。

例如：

<input type="Lastname" class="form-control" id="lnmae" placeholder="Enter Lastname" name="Lastname">

應該

<input type="text" class="form-control" id="Lastname" placeholder="Enter Lastname" name="Lastname">

，你首先必須要發展線上使用PHP Error Reporting，這將幫助，因爲你有一些語法錯誤，發現錯誤和警告你的代碼。

<?php 
// Same as error_reporting(E_ALL); 
ini_set('error_reporting', E_ALL); 

// Report all PHP errors (see changelog) 
error_reporting(E_ALL); 
?>

比你必須要了解HTML input field's types，對於假設，firstname和lastname字段是文本字段比你需要使用類似：

<input type="text" name="firstname"> 
<input type="text" name="lastname">

第三，非常重要的，你混合在mysql_*和mysqli_*擴展在一起，你需要執行查詢爲：

mysqli_query($con,$sql);

四，你的代碼是開放的SQL注入，你必須要防止SQL注入，您可以使用mysqli_real_escape_string()

例子：

// ist param should be link identifier. 
$Firstname = mysqli_real_escape_string($con,$_POST['Firstname']);

五，你缺少的<form>方法，和方法應該是POST，因爲你在你的代碼中使用$_POST，像

<form method="post" class="form-horizontal" action="user.php">

在最後，不硝酸鉀w，$username = "username";是你的數據庫的正確用戶，我希望這是root。

對密碼的建議：你必須要了解安全密碼，只是建議閱讀這個md5()。

側面說明：需要注意的是，mysql_*被棄用，接近PHP 7
