Question

I’m very new to php. I found some CMS like code for east text editing here on SO and now I’m trying to implement it on our micro site.
My problem is, that I want login error report to show on exact position on the page – just under the login button.
Can someone tell me how can I put that error report text whereever I want? I don’t want to override it with CSS positioning.

In basic, I want to put that p class=”error”:

<?php
    if (empty($_POST) && isset($_GET['action'])) {
            $action = $_GET['action'];
            switch ($action) {
                case 'logout':
                    session_unset();
                    session_destroy();
                    break;
        }
    }
      if (!isset($_SESSION['user'])) {
                $user = '';
                $pass = '';
                if (isset($_POST['login'])) {
                    $user = strtolower(trim($_POST['user']));
                    $pass = $_POST['pass'];
                    $errors = array();
                    if ($user == '' || $user != '1') {
                        $errors['user'] = '';
                    }
                    if ($pass == '' || $pass != '1') {
                        $errors['pass'] = '';
                    }
                    if (empty($errors)) {
                        $_SESSION['user'] = $user;
                    } else {
                        echo '<p class="error">Insert correct ';
                        if (isset($errors['user']))
                            echo 'name';
                        if (count($errors) == 2)
                            echo ' a ';
                        if (isset($errors['pass']))
                            echo 'password';
                        echo '.</p>', "\n";
                    }
                }
           }
    if (isset($_SESSION['user'])) {
        $user = $_SESSION['user'];
    ?>

somewhere else in the whole code of my page. Do I need to cut out something from that php code, or do I need to write new part of code for that?

Thank you for you help, Matej

Instead of just doing ‘echo’ all over the place, which means you get output at the place where the PHP code is embedded in the page, set some flags/message variables to output later.

e.g.

<?php

$errors = false;
$msgs = '';

if (....) {
   $errors = true;
   $msgs = "something dun gone wrong";
}
?>

... various bits of your html go here ...
<?php if ($errors) { echo $msgs; } ?>
... more html here ...
