私はPHPとHTMLでフォーラムを作ろうとしています。とにかく、これは正常に動作するために使用されていましたが、今ではこのエラーが発生しました。私はそれを修正する方法は分かりません。おそらくちょっとしたことです。SQLSTATE [23000]：整合性制約違反：1048カラム 'message'をnullにすることはできません。
<?php
session_start();
require_once 'class.user.php';
$user_home = new USER();
if(!$user_home->is_logged_in())
{
$user_home->redirect('index.php');
}
$stmt = $user_home->runQuery("SELECT * FROM tbl_users WHERE userID=:uid");
$stmt->execute(array(":uid"=>$_SESSION['userSession']));
$row = $stmt->fetch(PDO::FETCH_ASSOC);
?>
