please help... i am new to php. Thanks
php1 is to send a data ('1234') via method Post to php2. php2 is supposed to redirect using Header Location to php3 with a data ('invalid').
Developer Tools of Chrome indicate that everything went well (Post data sent and received. Get data sent and received). Somehow, the browser does not response and stay at php1. I have tried Safari and Firefox. No response. Would be really grateful if you could advise. Thanks
The 3 php files are:
php1
<?php
session_start();
$M = '';
if (isset($_GET['m'])) {
$M = $_GET['m'];
}
?>
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('#send').click(function () {
var str = '1234';
$.post('php2.php',
{
email: str
},
function (data, status) {
}
);
});
});
</script>
</head>
<body>
<div>
<button id="send">SEND</button>
<br>
<?php echo $M; ?>
</div>
</body>
</html>
php2
<?php
session_start();
ob_start();
error_reporting(E_ALL);
if (!empty($_POST)){
$Email = $_POST['email'];
if (!filter_var($Email, FILTER_VALIDATE_EMAIL)) {
header('Location: php3.php?m=invalid');
exit();
}
} else {
header('Location: php1.php?m=nodata');
exit();
}
ob_end_flush();
?>
php3
<?php
session_start();
$M = '';
if (isset($_GET['m'])) {
$M = $_GET['m'];
}
?>
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<div>
<?php echo $M; ?>
</div>
</body>
</html>
