Sveiki. Kā es šeit varētu sakārtot pēc postiem/karmas?
http://svens.exs.lv/activity
Tos datus izvelk ar šādu kodu:
if ($page == 'activity') {
echo '<div class="readbox">';
$logged_users = $db->query("SELECT * FROM log ORDER BY `log`.`id` ASC");
echo '<center>Vēlies tikt šeit pievienots? Dodies uz <a class="small Lietotājs" href="http://svens.exs.lv/track">http://svens.exs.lv/track</a><br />
<table class="mhm">
<tr>
<td>Lietotājvārds</td>
<td>Posti</td>
<td>Karma</td>
<td>Posti dienā</td>
<td>Karma dienā</td>
<td>Klase</td>
<td>Pēdējo reizi manīts</td>
</tr>';
$days = 'https://exs.lv/user_stats/json/16433';
$json_days = file_get_contents($days);
$decode_days = json_decode($json_days);
$print_days = $decode_days->{'days'} - 770;
while ($print = $logged_users->fetch_object()) {
$url = 'https://exs.lv/user_stats/json/' . $print->user_id . '';
$json = file_get_contents($url);
$decode = json_decode($json);
$posts = $decode->{'posts'} - $print->posts;
$karma = $decode->{'karma'} - $print->karma;
$nick = $decode->{'nick'};
$user_id = $decode->{'id'};
$lastseen = $decode->{'last_seen'};
$type = $decode->{'type'};
$time = time()- 8*60;
$time = date("Y-m-d H:i:s", $time);
if ($lastseen > $time) {
$star = '<span style="color:#FF8000">*</span>';
}
else {
$star = '';
}
if ($type == 'user') {
$type2 = 'Lietotājs';
}
else if ($type == 'moderator') {
$type2 = 'Moderators';
}
else if ($type == 'journalist') {
$type2 = 'RA';
}
else if ($type == 'admin') {
$type2 = 'Administrators';
}
echo '<tr>
<td><a class="small ' . $type2 . '" href="https://exs.lv/user/' . $user_id . '">' . $star . '' . $nick . '</a></td>
<td>' . $posts . '</td>
<td>' . $karma . '</td>
<td>' . round($posts/$print_days, 2) . '</td>
<td>' . round($karma/$print_days, 2) . '</td>

</tr>';
}
echo '</table><br /></center></div>';
}

Datubāzē tiek glabāti tikai lietotāju ID, atņemamais postu un karmas skaits.
