Итак, я использую этот код, чтобы проверить, вошел ли пользователь в систему и работает ли он, но только в одном файле:
$.ajax({
url: 'loginAndSingupAction.php',
type: 'post',
data: {
'username': username,
'password': password,
'action': 'login'
},
success: function(data) {
console.log(data);
if (data == 1) {
alert("hi")
$("#msg").text('Login efetuado com sucesso');
setTimeout(function() {
window.location.href = 'inicio'
}, 2000);
} else {
alert("bye");
$("#msg").text('credenciais inválidas');
}
}
});
Это полный файл, над которым работает приведенный выше код, и выдает предупреждение ( "Привет"). «login. php» (⬆️ приведенный выше код):
<?php
session_start();
if (isset($_SESSION['ip'])) {
$ip = $_SESSION['ip'];
//header("Location: index.php");
}
?>

Но когда я использую этот же код для индекса. php, он не выдает предупреждение («привет»), когда пользователь входит в систему. в. Работает только оповещение ("пока"). Почему? И как я могу это исправить?
вот индекс. php файл с включенным кодом (мне очень жаль, если файл слишком длинный, я обрезал до максимально возможного):
<?php
ini_set('display_errors', 0);
if (empty($_SESSION)) {
@session_start();
} /**/
if (isset($_SESSION['ip'])) {
$ip = $_SESSION['ip'];
}
if (isset($_GET['action']) && $_GET['action'] == 'logout') {
//unset($ip);
// header('Location:logout.php');
}
?>
