在提交表单之后但在重定向和退出之前回显成功消息

Question

Don't know how long i have worked on this, but nothing looks to be working. All i want to do is output a success message before it redirects and exits.

This is what i got to check for success/fail to the database

$sql = ("INSERT INTO test3 (test1, betvalue, bookmaker, status, aktiv) VALUES ('$bettype', '$betvalue', '$bookmaker', '$status', '$aktiv')");

    $result = mysqli_query($conn, $sql);
    if(mysqli_affected_rows($conn) >0 ) {
      echo "Wow it works";                    <-- Not working
      header("Location: nybonus.php");
      exit;
    } else {
      echo ("<div class='alert alert-danger' role='alert'>" . $sql . "</div><div class='alert alert-danger' role='alert'>" . mysqli_error($conn) . "</div>");
    }

It does not output any echo if it has be successful, i have tried making it sleep with correct flushing to try to output an messsage, but it does not work at all. Is there a better way to do it? Also can someone explain why it wont echo before the header and exit?

Answer 1

The problem is when you use the "header" it has to be first. You can't print anything else to the screen before the header. It's the same as when you're setting cookies.

So in your case you can't do the redirect with "header". You could use a meta refresh.

<meta http-equiv="refresh" content="0; url=http://www.somewebsite.com">

The "content" is number of seconds to wait before doing refresh.

Could you achieve what you want by setting a session variable and checking for the state of that variable on reload:

$message = '';
if(isset($_SESSION['success'])) {
    if($_SESSION['success'] == 'success') {
        $message = 'Success';
    }
}

$sql = ("INSERT INTO test3 (test1, betvalue, bookmaker, status, aktiv) VALUES ('$bettype', '$betvalue', '$bookmaker', '$status', '$aktiv')");
mysqli_query($conn, $sql);
if(mysqli_affected_rows($conn) > 0) {
    $_SESSION['success'] = 'success';             
    header('Location: nybonus.php');
    exit;
}
else {
    $_SESSION['success'] = 'fail';
    ..... 
}

<script>
$("#message").fadeOut(2000, function() {
    $("#message").fadeIn(0, function() {
        document.getElementById("message").innerHTML ="<br>";

    });
});
</script>

<div id="message">
    <?php echo $message; ?>
</div>

You'll have to explain what you're trying to accomplish more precisely... like step 1 do this step 2 do this and so on. Previously I understood you had asked how to do a redirect after echoing a message.

So now explain more detail in steps what you're wanting to do and maybe I can help.

If you mean the user is one "page1" and they submit a form and then on the resulting page you want to display the message? Then redirect...

You would just need to make the form action be the same url path as the page they are currently on.

Do you follow me?
