相关的PHP脚本（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"; 
} 




?>

当表单提交返回不成功注册！我该如何解决这个问题？

你需要使用适当的错误处理通过PHP和查询，你有一个在这里'，$ cpassword'）''。这是（主题）错字。 –

也许打开错误处理并回显错误（s）？ – mplungjan

也许缺少的报价是问题？ '$ password'，>>>> $ cpassword' – mplungjan

$ SQL = “INSERT INTO signup VALUES（ '$ FNAME'， '$ L-NAME'， '$地址'， '$联系'， '$电子邮件'， '$密码'，$ cpassword'）” ;

你错过了最后一个变量。你有'$密码'，$ cpassword'< -----失踪'。还要更改“注册”周围的勾号。

试试这个：

$ SQL =“INSERT INTO '注册' VALUES（ '$ FNAME'， '$ L-NAME'， '$地址'， '$联系'， '$电子邮件'，” $密码”， '$ cpassword'）“;
