제출 된 데이터가 MySQL에 VarChar에 1, Int에 0으로 저장됩니다.

Question

내 학기 프로젝트에 Facebook과 비슷한 것을 만들고 몇 가지 문제가 있습니다.

양식을 통해 값을 게시하고 데이터베이스에 저장하려고하면 데이터베이스에 저장된 데이터는 VarChar 데이터 형식의 경우 1이고 Int 데이터 형식의 경우 0과 같습니다.

나는 오류를 찾을 수 없습니다. 내 HTML과 PHP 코드는 다음과 같습니다 : 당신은 true 또는 false 중 하나입니다 isset($_POST['XXX'])의 결과로 모든 변수를 설정하는

<?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"); 

?>

Answer 1

아닌 입력 필드 자체의 값으로 설정합니다. 그래서

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

는해야한다 : 다른 모든 변수에 대한

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

와 유사합니다.
