I am stuck at an error in my PHP. Someone that can help me?

I get this error:

> 
> You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'fulltext, surl, burl, date) VALUES 'Webite is online!', 'This is a short text lo' at line 1
> 
> 
> 

And this is my code:

```
<?php
if(isset($_POST['submit'])) {
        if(!empty($_POST['titel']) && !empty($_POST['stext']) && !empty($_POST['fulltext']) && !empty($_POST['surl']) && !empty($_POST['burl'])) {
            $titel = secure($_POST['titel']);
            $stext = secure($_POST['stext']);
            $fulltext = secure($_POST['fulltext']);
            $surl = secure($_POST['surl']);
            $burl = secure($_POST['burl']);
            $date = date('d/m/y H:i:s');

                    $sql = mysql_query("INSERT INTO news (titel, stext, fulltext, surl, burl, date) VALUES '".$titel."', '".$stext."', '".$fulltext."', '".$surl."', '".$burl."', '".$date."'")or die(mysql_error());
                    if($sql) {
                        echo('News posted succesful.');
                        echo('<meta http-equiv="refresh" content="3" />');
                    } else {
                        echo'There was an error, please try again.';
                        echo('<meta http-equiv="refresh" content="3" />');
                    }
        } else {
            echo('Not all fields are filled.');
            echo('<meta http-equiv="refresh" content="3" />');
        }
    } else {
        echo('
        <form method="post" action="#">
        <table width="100%" cellpadding="0" cellspacing="2">
        <tr>
