Add-on Need help about my simple add-on.

[Kyris]

Hi all,

I'm using xenForo and very interested in creating Add-on, but i'm a freshmen and know very few about xenForo Add-on developing. So I wrote here to need everyone help.

My add-on (in my head) is about a dropdown list can show news, announcements - and I called it is Release. It very simple, I input a title and a link, and it'll show in forum (below navbar), that's all.

But my problems start from how to integrate between database and template. I searched and it look like i'll use template hook, but i don't know how to use it... i viewed the video about this (made by Kier) but i'm confused

And another problem is about add new title and link via admincp (i input and they will list in the history in my add-on control)...

I'm really confused about this problems Please help me.
Thank you!

This is my codes

<?php
class Horizon_Release_showEps
{
public function show()
{
$host='localhost';
$user='root';
$pass='';
$db='xfhor';
$con = mysql_connect($host,$user,$pass);
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db($db, $con);

$sql = mysql_query("SELECT * FROM horizonrel ORDER BY id DESC");
while($row = mysql_fetch_array($sql))
{
echo $row['id'].' - '.$row['name'].' - '.$row['link'].'</br>';
}
mysql_close($con);
}
}
?>

I tried with PHP Callback, and it showed errors

An exception occurred: call_user_func() expects parameter 1 to be a valid callback, non-static method Horizon_Release_showEps::show() should not be called statically in F:\WAMP\www\xf113\library\XenForo\ViewAdmin\Helper\Option.php on line 327
