Thread data manager and line breaks

[TiKu]

Hi,

I want to use data manager to create a new thread and I want the first post to contain line breaks. But I don't want to make the forum allow HTML, so I cannot use <br>.
Here's my code:

$threaddm =& datamanager_init('Thread_FirstPost', $vbulletin, ERRTYPE_ARRAY, 'threadpost');
$forumid = 27;
$userid = 33256;
// $mytitle and $mytext actually come from extern
$title = addslashes($mytitle);
$pagetext = addslashes($mytext);
$url = 'http://www.google.de';     // just a sample
$pagetext .= '\n\nClick here';
$allowsmilie = '0';
$visible = '1';

$foruminfo = fetch_foruminfo($forumid);
$threadinfo = array();
$user = htmlspecialchars_uni(fetch_userinfo($userid));

$threaddm->set_info('forum', $foruminfo);
$threaddm->set_info('thread', $threadinfo);
$threaddm->setr('forumid', $forumid);
$threaddm->setr('userid', $userid);
$threaddm->setr('pagetext', $pagetext);
$threaddm->setr('title', $title);
$threaddm->set('allowsmilie', $allowsmilie);
$threaddm->set('visible', $visible);

$threadid = $threaddm->save();

With this code, the created post looks like this:

Bla\n\nClick here

I want it to look like this:

Bla

Click here

What am I doing wrong?
