Question

我正在尝试为我的学期项目创建类似于Facebook的东西，并遇到一些问题。

当我通过表单发布值并尝试将其保存在我的数据库中时，存储在数据库中的数据对于VarChar数据类型为1，对于Int数据类型为0。

我无法找到错误。我的HTML和PHP代码如下：

<?php
$db_host="localhost";
$db_username="root";
$db_password="vertrigo";
$db_name="php_db";

mysql_connect($db_host,$db_username,$db_password) or die("Couldn't connnect  to the database");
mysql_select_db("php_db") or die("Couldn't connnect to the database");

?>

<form name="reg" action="signup.php"  method="post">

Answer 1

您要将所有变量设置为isset($_POST['XXX'])的结果，true或false，而不是输入字段本身的值。所以

$first_name = isset($_POST['fname']);

应该是：

$first_name = isset($_POST['fname']) ? $_POST['fname'] : '';

和所有其他变量类似。

保存到MySQL的数据为VarChar为1，Int为0
