ROZWIĄZANY: Błąd w składni

[Gama]

Witajcie. Otóż chciałem dodać na forum licznik osób grających na serwerze. Jednak przy próbie dodania kodu podanego poniżej do szablonu globalTemplate wywala mi błąd "Występuje błąd w składni w szablonie(...)"

Potrzebuje pomocy bo nie wiem jak wyedytować ten kod w taki sposób żeby działał poprawnie.

Oto ten kod:

<li id="SA:MP Server Query Script" class="left">
<span style="background-color:#d5dde5;font-size:0.8em;padding:2px 5px;-moz-border-radius:6px;-webkit-border-radius:6px;border-radius:6px;color:#000;text-decoration:none;z-index:5000" title="Aktualizowane co minutę.">
Graczy online: <b>
<?php 
require('SampQueryAPI.php'); 
$query = new SampQueryAPI('89.74.50.207', 8000); // adres, port
$info = $query -> getInfo();
echo $info['players'];
?></b>
</span></li>

Plik SampQueryAPI.php znajduje się w katalogu głównym forum (obok pliku index.php i folderu admin)

Z góry dzięki za pomoc

Oj oj, zamiast <?php i ?> dajesz <php> i </php>. Zamiast 'echo' dajesz zmienną, a pod kodem </php> dajesz {$nazwaTejZmiennej}.

[Gama]

Zrobiłem tak, uporządkowałem kod, otrzymałem taki kod (prawda?):

<php> 
require('SampQueryAPI.php'); 
$query = new SampQueryAPI('training.truck-drive.pl', 7781); // adres, port
$info = $query -> getInfo();
$iloscgraczy = $info['players'];
</php>
<li id="SA:MP Server Query Script" class="left">
<span style="background-color:#d5dde5;font-size:0.8em;padding:2px 5px;-moz-border-radius:6px;-webkit-border-radius:6px;border-radius:6px;color:#000;text-decoration:none;z-index:5000" title="Aktualizowane co minutę.">
Graczy online: {$iloscgraczy}
</span></li>

I otrzymałem bardzo ciekawe błędy:

(Po usunięciu kodu, forum działa normalnie)

[DawPi]

A daj require_once.

[Gama]

Ten sam błąd, tylko że został ten pierwszy

mySQL query error: SELECT * FROM skin_cache WHERE cache_set_id=6 AND cache_value_1='skin_forums_global'

[DawPi]

<php> 
require('SampQueryAPI.php'); 
$query = new SampQueryAPI('training.truck-drive.pl', 7781); // adres, port
$info = $query->getInfo();
$iloscgraczy = $info['players'];
</php>

Też lipa?

[Gama]

Nie działa ale pojawił się inny błąd. A mianowicie 500 Internal Server Error

[DawPi]

A tak:

<php> 
require('SampQueryAPI.php'); 
$this->query = new SampQueryAPI('training.truck-drive.pl', 7781); // adres, port
$info = $this->query->getInfo();
$iloscgraczy = $info['players'];
</php>

[Gama]

Teraz powrócił błąd

mySQL query error: SELECT * FROM skin_cache WHERE cache_set_id=6 AND cache_value_1='skin_forums_global'

Dzięki DawPi że się nie poddajesz

[DawPi]

Wykonaj takie zapytanie:

SELECT * FROM skin_cache WHERE cache_set_id=6 AND cache_value_1='skin_forums_global'

W PhpMyAdminie i podaj wynik - pewnie błąd, ale jaki.

[Gama]

Otóż chyba nie ma błędu (chyba?)

[DawPi]

Ano błędu nie ma i tego się obawiałem, bo kod był poprawny.

Czy po takim kodzie coś się wysypuje:

<php> 
require('SampQueryAPI.php'); 
$this->query = new SampQueryAPI('training.truck-drive.pl', 7781); // adres, port
</php>

A potem po takim:

<php> 
require('SampQueryAPI.php'); 
$this->query = new SampQueryAPI('training.truck-drive.pl', 7781); // adres, port
$info = $this->query->getInfo();
</php>

[Gama]

Zarówno po kodzie

<php> 
require('SampQueryAPI.php'); 
$this->query = new SampQueryAPI('training.truck-drive.pl', 7781); // adres, port
</php>

jak i

<php> 
require('SampQueryAPI.php'); 
$this->query = new SampQueryAPI('training.truck-drive.pl', 7781); // adres, port
$info = $this->query->getInfo();
</php>

Wywala błąd

mySQL query error: SELECT * FROM skin_cache WHERE cache_set_id=6 AND cache_value_1='skin_forums_global'

A tak:

<php> 
require('SampQueryAPI.php'); 
</php>

No i wklej zawartość tego pliku.

[Gama]

A więc po dodaniu tego kodu:

<php> 
require('SampQueryAPI.php'); 
</php>

Forum działa normalnie, bez błędów

A tu zawartość pliku SampQueryAPI.php

To chyba należałoby zrobić przy pomocy rozszerzenia do skina, a nie bezpośrednio w skinie.

[Gama]

A możesz mi jakoś to objaśnić lub podać jakiś link do strony z jakimiś przykładami/objaśnieniami (może być po angielsku) ?
