私は現在、友達とpdoを使用するphpライセンスキーログインを開発していますが、このように現在表示されているページと同じページにエラーメッセージを表示する必要がありますphpの同じページにエラーメッセージを表示するには
<?php
define('DB_HOST', 'localhost');
define('DB_NAME', 'sprx');
define('DB_USERNAME', 'root');
define('DB_PASSWORD', '');
define('ERRMSG', 'ERROR: SOMETHING IS WRONG!');
try {
$odb = new PDO('mysql:host=' . DB_HOST . ';dbname=' . DB_NAME, DB_USERNAME, DB_PASSWORD);
}
catch(PDOException $Exception) {
die(ERRMSG);
}
function error($string)
{
return '<div class="alert alert-danger alert-dismissable"><button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button><strong>ERROR:</strong> '.$string.'</div>';
}
function success($string)
{
return '<div class="alert alert-success alert-dismissable"><button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button><strong>SUCCESS:</strong> '.$string.'</div>';
}
define('DIRECT', TRUE);
require 'func.php';
$user = new user;
?>
マイログイン：
<?php
require 'inc/php/php.php';
if ($user -> LoggedIn())
{
header('Location: index');
die();
}
?>

では
を交換して、ページのエラーメッセージのみ、残りの表示が死にかけている
を引き起こしていますAJAXを使用する必要があるかもしれません。 –
既に提案されているように、javascriptでjquery ajaxまたはxhrリクエストを使用してそれを達成してください。 – Daenarys
私はその使い方に慣れていません。説明してください。 –
