Manuprāt šis jau saknē nav pareizs domu gājiens. Mēs sen sen atpakaļ mēģinājām šādu sistēmu izmantot, bet tā beigu beigās pārvērtās par mērenu murgu ar visām kešotajām versijām, versiju pacelšanām, utt.

Daudz labāks risinājums ir publiski likt jau vienu sapakotu failu un atsevišķus specifiskos failus lādēt atsevišķi.

Iedomājies situāciju, kad tev ir teiksim 20 dažādi CSS faili, tu viņus atkarībā no vajadzības kombinē teiksim 400 kombinācijās. Pamaini vienu CSS failu un tev kaut kādā brīdī lietotājiem ir atkal jānovelk 400 dažādas failu kombinācijas, kā rezultātā viss ir slikti. Labāk sapako vienu universālu CSS failu jau pirms likšanas publiskajā vidē un paļaujies uz to, ka pārlūks to iekešos. Būs stipri labāk.

Es arī nevaru iedomāties iemeslu, kāpēc reset.css saturs nevarētu atrasties global.css iekšienē.

TheQn · August 11, 2011

Sis combine scripts comprese css,js failus tikai vienu reizi, un nem no cache folderi kam lietotajam piemeram cache-fwqfqw432423423f4f2f4.js.gzip nu nelade katram lietotajom compress css strada tika ta <link rel="stylesheet" type="text/css" href="/engine/combine.php?type=css&files=reset,global" /> nezinu kapec vins negrib stradat caur .htaccess sada veida RewriteRule ^css/(.*\.css)$ /engine/combine.php?type=css&files=$1

jo es taisu savu cms man vajag tikai so combine.php lai stradatu.

man liekas ta problema ir combine.php scripta jo es nevaru atrast so kludu scripta. busu pateicigs kurs atradis kludu un izlabos.

Sāc ar to, ka skaties, ko tev rāda access vai error log.

TheQn · August 11, 2011

vo ko uzrada access

ip - - [11/Aug/2011:14:18:32 +0300] "GET /css/reset.css,global.css HTTP/1.1" 404 20

ip - - [11/Aug/2011:14:18:47 +0300] "GET /css/reset.css,global.css HTTP/1.1" 404 20

ip - - [11/Aug/2011:14:18:50 +0300] "GET /css/reset.css,global.css HTTP/1.1" 404 20

bet nezinu kapec rada 404 ja es ieliku pareizu celu lids css folderim pasa combine.php, un .htaccess bet kludu nevaru atrast.

Fails ar nosaukumu 'reset.css,global.css' eksistē? :P

TheQn · August 11, 2011

ja eksiste

briedis · August 11, 2011

ja tu atver pārlūkā pats www.lblabla.lv/css/reset.css,global.css tad rādās atbilstošais fails?

TheQn · August 11, 2011

tikai baltu rapu uzrada.

briedis · August 11, 2011

nu tad ir jāsāk debugot. Skaties, cik tālu tas skripts izpildās un vai vispār viņš tiek izsaukts.

Kaut vai ar echo "esmu šeit" ievietošanu dažādās koda vietās...

daGrevis · August 11, 2011

Kādā sakarā faila nosaukumā Tev ir divi faila nosaukumi, kad atdalīti ar komatu??

TheQn · August 11, 2011

si koda dala urzrada Here!

elseif ($type == 'css' && substr($path, -4) !== '.css')
{
   	$file .= '.css';
   	echo "Here";
}

si koda dala neko neuzrada

if ($type === 'css')
{
$contents = preg_replace('!/\*[^*]*\*+([^/][^*]*\*+)*/!', '', $contents);
 $contents = str_replace(array("\r", "\n", "\t", '  ', '   '), '', $contents);
   	$contents = str_replace('{ ','{', $contents);
   	$contents = str_replace(' }','}', $contents);
   	$contents = str_replace('; ',';', $contents);
   	$contents = str_replace(', ',',', $contents);
   	$contents = str_replace(' {','{', $contents);
   	$contents = str_replace('} ','}', $contents);
   	$contents = str_replace(': ',':', $contents);
   	$contents = str_replace(' ,',',', $contents);
   	$contents = str_replace(' ;',';', $contents);
   	echo "here";
}

lieku echo kur ir apstrada ar css faili.

taisiju vel ta var_dump($cssdir);, var_dump($files);, var_dump($file); vispar neko neuzrada.

daGrevis · August 11, 2011

Tas, ka mainīs ko un kā izvadīsi - neko nedos. :D Tev tagad ir jānoskaidro, kāpēc skripts tajā blokā negrib pildīties. :)

TheQn · August 11, 2011

kods ir 100% pareizi uzrakstits, es pats nesaprotu kur kluda, es vel meginaju error_reporting(E_ALL) un error_reporting(8191) kludas koda neradas.

<pre id="line1">string(18) "C:\AppServ\www/css" </pre>

var_dump($types); null uzrada

<pre id="line1">string(20) "reset.css,global.css" vis pareizi</pre>
