foreach($l_news as $key => $event_id)
    {
        echo "\t<tr>\n";
        for($flag = 1; $flag <= 13; $flag ++)
        {
            
            if(isset($priority[$flag]["event_id"]))
            {
                if($event_id == $priority[$flag]["event_id"])
                {
                    echo "\t\t<td>[b]$event_id{$tipo}[/b]</td>\n";
                }
                else
                {
                    echo "\t\t<td>[url='p_insert.php?event_id=$event_id&tipo=$tipo&flags=$flag']$event_id{$tipo}[/url]</td>\n";
                }
            }
            else
            {
                echo "\t\t<td>[url='p_insert.php?event_id=$event_id&tipo=$tipo&flags=$flag']$event_id{$tipo}[/url]</td>\n";
            }
        }
        echo "\t</tr>\n";
    }
