相關的PHP腳本（ignupaction.php）上述HTML形式如下

<?php 

//importing db.php in the includes folder 

require("includes/db.php"); 


$fname=$_POST["firstname"]; 
$lname=$_POST["lastname"]; 

$address=$_POST["address"]; 
$contact=$_POST["contactno"]; 
$email=$_POST["emailaddress"]; 

$password=$_POST["password"]; 
$cpassword=$_POST["cpassword"]; 



$sql="INSERT INTO `signup` VALUES ('$fname','$lname','$address','$contact','$email','$password',$cpassword')"; 



$result=mysqli_query($db,$sql); 

if(!$result){ 
    echo "Unsuccessful signup"; 
} 
else{ 
    echo "Successful signup"; 
} 




?>

當表單提交返回不成功註冊！我該如何解決這個問題？

你需要使用適當的錯誤處理通過PHP和查詢，你有一個在這裏'，$ cpassword'）''。這是（主題）錯字。 –

也許打開錯誤處理並回顯錯誤（s）？ – mplungjan

也許缺少的報價是問題？ '$ password'，>>>> $ cpassword' – mplungjan

$ SQL = 「INSERT INTO signup VALUES（ '$ FNAME'， '$ L-NAME'， '$地址'， '$聯繫'， '$電子郵件'， '$密碼'，$ cpassword'）」 ;

你錯過了最後一個變量。你有'$密碼'，$ cpassword'< -----失蹤'。還要更改「註冊」周圍的勾號。

試試這個：

$ SQL =「INSERT INTO '註冊' VALUES（ '$ FNAME'， '$ L-NAME'， '$地址'， '$聯繫'， '$電子郵件'，」 $密碼」， '$ cpassword'）「;
