Problems hook (news)

[Dadou76620]

Hello I create a hook and my function shows me his results 1

 

My hooks.php

use Illuminate\Database\Capsule\Manager as Capsule;

$pdo = Capsule::connection()->getPdo();
$pdo->beginTransaction();

function simple_news_hook_clientarea($vars)
{
global $smarty;

$statement = $pdo->prepare("SELECT * FROM mod_simple_news ORDER BY idnews DESC");
$statement->execute();
$pdo->commit();

$list_news = array();
$i = 0;
while($data = $statement->fetch()){
	$list_news[$i]['idnews'] = $data['idnews'];
	$list_news[$i]['titre'] = $data['titre'];
	$list_news[$i]['news'] = $data['news'];
	$list_news[$i]['date'] = $data['date'];
	$list_news[$i]['auteur'] = $data['auteur'];
	$i++;
}

$smarty->assign('list_news', $list_news);
}

add_hook('ClientAreaHeaderOutput', 1, 'simple_news_hook_clientarea');

 

My file TPL

{$list_news|print_r}

 

$list_news displays '1' I have an error in my function?

 

Thank you for your help
