Sprawdzanie w szablonach (<if></if>) Opcje

[gulldarek]

Mam taka funkcje:

[php:1:29914852a5]<?php
function gettemplate($templatename, $gethtmlcomments = 1)
{
if(file_exists("templates/$templatename.htm")){

$fd = fopen ("templates/$templatename.htm", "r");

$template_file = fread ($fd, filesize ("templates/$templatename.htm"));
$template = preg_replace_callback('/{_([^ ]+)}/U', create_function('$matchs', 'return $GLOBALS["lang_$matchs[1]"];'), $template_file);

$template = preg_replace_callback('/{([^ ]+)}/U', create_function('$matches', 'return $GLOBALS[$matches[1]];'), $template);

if ($options['addtemplatename'] = 1 AND $gethtmlcomments = 1)
{
$template = "n<!-- POCZATEK SZABLONU: $templatename -->n$templaten<!-- KONIEC SZABLONU: $templatename -->n";
}

fclose($fd);

return $template;

} else {

return "<center><font color="red">Wystapil blad krytyczny - Brak szablonu '$tplfile'. Skontaktuj sie z administratorem.</font></center>";

}

}

?>[/php:1:29914852a5]

Chce miec mozliwosc dodania do szablonu czegos takiego:

Kod

<if condition="$show"> tutaj tresc strony </if>

i jesli funkcja natrafi na taki kod zeby sprawdzila czy np. $show == 1, a jesli tak to wyswietlila kod miedzy znacznikiem <if></if>.

Ma ktos pomysl jak to zrobic?

Może mój template ciebie zainteresuje.
Posiada obsługe multisesji, ifów. nie przeszkadzają mu złożone konstrukcje.
