I am going to try to explain but I manage not very well in English. In fact, I already use 'recentitems' other leave in the design. Actually, i use the plugin 'News' and i also parametrized him to see 4 news.

For the design of my website, I need both. (news & my_plug[mininews])

You know how to see on the image what I wish to make

http://hpics.li/3048c75

That's why I wish to make this plugin, to show 4 right images

Added 36 minutes later:

Later of numerous copy/paste, I finally managed to show what I wished \o/

To be frank, I have no idea of why it works. This is what I modified :

mininews.index.php

/* ====================
[BEGIN_COT_EXT]
Hooks=index.tags
Tags=index.tpl:{MININEWS}
[END_COT_EXT]
==================== */

defined('COT_CODE') or die('Wrong URL');

	$ttt = new XTemplate(cot_tplfile('mininews.index', 'plug'));

	$sql = $db->query("SELECT page_alias, page_title, page_avatar 
			FROM $db_pages 
			WHERE page_cat = 'news' 
			ORDER BY page_id DESC 
			Limit 4");
						
	/* === Hook - Part1 === */
	$extp = cot_getextplugins('mininews.index.tags');
	/* ===== */					

	foreach ($sql->fetchAll() as $row)
	{
    	$ttt->assign(array(
            'PAGESS_ALIAS' => htmlspecialchars($row['page_alias']),
			'PAGESS_TITLE' => htmlspecialchars($row['page_title']),
			'PAGESS_AVATAR' => $row['page_avatar']
    	));
		
		/* === Hook - Part2 === */
		foreach ($extp as $pl)
		{
			include $pl;
		}
		/* ===== */
		
		$ttt->parse('MININEWS');
	}
	
	$t->assign('MININEWS', $ttt->text('MININEWS'));

I come towards you because I try to create a plugin which displays on page index. I need that he shows only the information of 4 back pages(news)

I tried some solution but I become muddled with =>   $t = new XTemplate(cot_tplfile.....

Here is my code:

mininews.index.php

/* ====================
[BEGIN_COT_EXT]
Hooks=index.tags
Tags=index.tpl:{MININEWS}
[END_COT_EXT]
==================== */

defined('COT_CODE') or die('Wrong URL');

	$t = new XTemplate(cot_tplfile('mininews', 'plug'));

	$sql = $db->query("SELECT page_alias, page_title, page_avatar 
			   FROM $db_pages 
			   WHERE page_cat = 'news' 
			   ORDER BY page_id DESC 
			   Limit 4");

	while($row = $sql->fetch())
	{
    	$t->assign(array(
            'PAGESS_ALIAS' => htmlspecialchars($row['page_alias']),
	    'PAGESS_TITLE' => htmlspecialchars($row['page_title']),
	    'PAGESS_AVATAR' => $row['page_avatar']
    	));
	    $t->parse('MININEWS');
	}

mininews.index.tpl

<!-- BEGIN: MININEWS -->
<div>{PAGESS_ALIAS}{PAGESS_TITLE}{PAGESS_AVATAR}</div>
<!-- END: MININEWS -->

mininews.setup.php

/* ====================

With this code, nothing displays and I do not manage to understand why :'(
