Question

I created the add comment script.

Source –

if (isset($_GET['do']) and $_GET['do'] == 'comment'){//Ja viss kārtībā, turpinam
                if (!empty($_POST['name']) and !empty($_POST['artcl_id']) and !empty($_POST['homepage']) and !empty($_POST['text'])){
                    $name = trim($_POST['name'],' ');
                    $artcl_id = trim($_POST['artcl_id'],' ');
                    $homepage = trim($_POST['homepage'],' ');
                    $text = trim($_POST['text'],' ');
                    Model::factory('index')
                            ->send_commentar(mysql_real_escape_string($name), mysql_real_escape_string($artcl_id), mysql_escape_string($homepage), mysql_real_escape_string($text), mysql_real_escape_string(time()));
                    ?>
                    <script type="text/javascript">
                        alert("Thank you! :)");
                    </script>
                    <meta http-equiv="REFRESH" content="0;url=/article/<?php echo $slug; ?>"/>
                    <?php

                } else {
                    $this->template->content = View::factory('index/error')->set('message', 'How to submit empty comment?');
                }
        }

But if I am putting white spaces in input field, the script send white spaces. Why the script don’t work correctly?

Answer 1

You’re removing whitespaces after you checked on empty fields. Don’t you want that turned around? First remove whitespaces and then checking for empty fields?
