大家好，早上好。
我有一个问题，我正在尝试使用PHP将我的注册表单链接到我的数据库，所以当有人填写表单时，所有数据都应该进入数据库，但问题是它不起作用，代码传递所有内容，他转到ELSE句子，请让我知道我做错了什么，如果有解决方案，请解释一下，以便我从中学习。
代码有趣的最后一个假句子。
PHP代码：
$hostname="*************";
$username="*************";
$password="*************";
$database="*************";
$connect=mysql_connect($hostname,$username,$password);
if(!$connect)
{
die('Connection Failed'.mysql_error());
}
mysql_select_db($database);
if(isset($_REQUEST['Submit']))
{
$username = ($_REQUEST['username']); // SANITIZE INPUTS !
$firstname = ($_REQUEST['firstname']);
$pincode = ($_REQUEST['pincode']);
$lastname = ($_REQUEST['lastname']);
$email = ($_REQUEST['email']);
$password = ($_REQUEST['password']);
$website = ($_REQUEST['website']);
$phonenumber = ($_REQUEST['phonenumber']);
$zipcode = ($_REQUEST['zipcode']);
$address1 = ($_REQUEST['address1']);
$address2 = ($_REQUEST['address2']);
$company = ($_REQUEST['company']);
$sq = ($_REQUEST['sq']);
$country = ($_REQUEST['Country']);
$city = ($_REQUEST['city']);
$sql = "INSERT INTO customers
VALUES (0,'$pincode','$username','$firstname','$lastname',
'$email','$password', '$sq', '$company', '$website',
'$address1', '$address2', '$city','$zipcode',
'$country')";
$res=mysql_query($sql);
if($res)
{
echo "Sumbimted";
}
else
{
echo "Something went wrong ";
}
}
else
{
echo "false";
}
?>
我的表单页面代码 ：

我假设它正在显示
Something went wrong消息
您没有正确测试查询处理中的错误。
如果您显示数据库生成的错误，它将帮助您解决问题，而不仅仅是echo "Something went wrong ";
因此，请更改此部分：
if($res === false) {
echo 'Query failed ' . mysql_error();
echo "'n$sql'n";
exit;
} else {
echo "Submited";
}
哦，就像我上面说的：
请不要使用
mysql_数据库扩展，它 已弃用（在 PHP7 中永远消失） 特别是如果你只是在学习PHP，把你的精力花在学习PDO数据库扩展上。 从这里开始
我在这里猜测，但我猜你不需要 VALUES 子句中的第一个参数，即 VALUES (0,因为我假设这是一个auto-increment列，所以总是使用 0 会导致错误。
如果是这种情况，请不要添加该参数，即
VALUES ('$pincode','$username','$firstname','$lastname',
'$email','$password', '$sq', '$company', '$website',
'$address1', '$address2', '$city','$zipcode',
'$country')";
或传递空
VALUES (NULL,'$pincode','$username','$firstname','$lastname',
'$email','$password', '$sq', '$company', '$website',
'$address1', '$address2', '$city','$zipcode',
'$country')";
完全关闭它更简单
交替
您可能以错误的顺序获取参数，即与数据库定义的顺序不匹配。在这种情况下，它可能会失败，因为数据类型不匹配，或者传递的数据对于它所在的列来说太大。
使用表单总是最安全的
INSERT INTO Table (column1, column2) VALUES ('data1', 'data2' )
确保值进入正确的列。请记住，总是可以更改数据库中的列，添加/删除并影响列的默认顺序，然后所有此类语句都将失败，您必须搜索代码以查找发生的奇怪错误。请记住，修改表格布局的可能不是您。
列顺序错误
您不会从屏幕上的用户那里收集C_securityanswer。因此，您不会将其传递给查询！因此，上面我调用 Alternative 的部分将生效，并且以下所有列都是 1 漂移。这实际上并不会导致问题（数据类型或列大小 wize），直到我们尝试将 TEXT $country放入列C_zipcode这是一个 int（10），在那里它会匆忙变坏。
实际上，该字段可能不应该是 int，但这就是导致查询失败的原因。
$sql = "INSERT INTO customers
VALUES (0,'$pincode','$username','$firstname','$lastname',
'$email','$password', '$sq',
??? there is a column here on the database
'$company', '$website',
'$address1', '$address2', '$city','$zipcode',
'$country')";
但是，您当前错误的真正原因是您已经删除了此行
$res=mysql_query($sql);
因此，查询实际上永远不会运行!!!呜
