剥离DISCUZ X系列的模板引擎机制
首先定义几个常量
1 2 3 4 5 6 7 8 9 |
define('DISCUZ_ROOT',dirname(__FILE__)); define('IN_DISCUZ',true); define('STYLEID',1); define('TEMPLATEID',1); define('TPLDIR','templates/default'); |
这些常量是必须要定义的。
其次把需要的函数分出来。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 |
function strexists($string, $find) { return !(strpos($string, $find) === FALSE); } function template($file, $templateid = 0, $tpldir = '', $gettplfile = 0, $primaltpl='') { $tpldir = $tpldir ? $tpldir : (defined('TPLDIR') ? TPLDIR : ''); $tpldir = './'.$tpldir; $templateid = $templateid ? $templateid : (defined('TEMPLATEID') ? TEMPLATEID : ''); $tplfile = ($tpldir ? $tpldir.'/' : './template/').$file.'.htm'; $filebak = $file; $file == 'common/header' && defined('CURMODULE') && CURMODULE && $file = 'common/header_'.$_G['basescript'].'_'.CURMODULE; $cachefile = './data/template/'.(defined('STYLEID') ? STYLEID.'_' : '_').$templateid.'_'.str_replace('/', '_', $file).'.tpl.php'; if($templateid != 1 && !file_exists(DISCUZ_ROOT.$tplfile)) { $tplfile = './template/default/'.$filebak.'.htm'; } if($gettplfile) { return $tplfile; } checktplrefresh($tplfile, $tplfile, @filemtime(DISCUZ_ROOT.$cachefile), $templateid, $cachefile, $tpldir, $file); return DISCUZ_ROOT.$cachefile; } function checktplrefresh($maintpl, $subtpl, $timecompare, $templateid, $cachefile, $tpldir, $file) { static $tplrefresh, $timestamp, $targettplname; if(empty($timecompare) || $tplrefresh == 1 || ($tplrefresh > 1 && !($timestamp % $tplrefresh))) { if(empty($timecompare) || @filemtime(DISCUZ_ROOT.$subtpl) > $timecompare) { require_once DISCUZ_ROOT.'./class_template.php'; $template = new template(); $template->parse_template($maintpl, $templateid, $tpldir, $file, $cachefile); return TRUE; } } return FALSE; } |
其中解析使用的函数为function template;
在此，修改template类

基本工作完成。
