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?

Dziala mi juz sprawdzanie, ale zrobilem troche inaczej. Znaczniki musza wygladac tak:

[xml:1:0d9ab2f477]<if condition="($cos['cos'] == 1)">COS<else />NIE COS</if condition="($cos['cos'] == 1)">[/xml:1:0d9ab2f477]

Ok, ostatnia wersja mojego systemu szablonow wyglada tak:

[php:1:0d9ab2f477]<?php

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

if (substr_count($template,'</if') >= 1)
{
$template = template_conditionals($template);
}

if ($options['addtemplatename'] == 1 AND $gethtmlcomments == 1)
{
$template = "rn<!-- BEGIN TEMPLATE: " . $templatename . " -->n" . $template . "n<!-- END TEMPLATE: " . $templatename . " -->rn";
}

if ($options['templatecompressor'] == 1)
{
//$page_byte = strlen($template);
$template = preg_replace ("/(>)(s*)(rn)*(s*)(<)/", '15', $template);

//$pagenew_byte=strlen($template);
//$page_kilobyte=number_format(($page_byte/1024),2); // echo strpos($vartext,">rn<");exit;
//$pagenew_kilobyte=number_format(($pagenew_byte/1024),2);
//$pagesaved_byte=$page_byte-$pagenew_byte;
//$pagesaved_kilobyte=number_format((($pagesaved_byte)/1024),2);
//$pagesaved_perc=number_format(((100*$pagesaved_byte)/$page_byte),2);

//$output .= "<br> [Prawdziwa "waga": " . $page_kilobyte . " Kb. skompresowana do <b>" . $pagenew_kilobyte . "</b> Kb. oszczedzajac <b>" . $pagesaved_kilobyte . "</b> Kb. (" . $pagesaved_perc% . ")] ";
}

fclose($fd);

if ($print == 1)
{
echo $template;
}
else
{
return $template;
}

}
else
{

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