./upload/forum.php

 

这是forum.php的全部代码，然后试着读一读，自己做做笔记。

 

define('APPTYPEID', 2);
define('CURSCRIPT', 'forum');

 

define(); 定义常量的函数，结果为  apptypeid = 2, curscript = 'forum'。

为何这么设定，还不知道。

 

require './source/class/class_core.php';
require './source/function/function_forum.php';

导入2个文件

class_core.php  - 论坛的主要类文件，core类和c类，都是在这个文件中定义的

function_forum.php - 论坛forum模块使用的函数，都放在这个文件中。

 

 

$modarray = array('ajax','announcement','attachment','forumdisplay',
    'group','image','index','medal','misc','modcp','notice','post','redirect',
    'relatekw','relatethread','rss','topicadmin','trade','viewthread','tag','collection','guide'
);


$modcachelist = array(
    'index'        => array('announcements', 'onlinelist', 'forumlinks',
            'heats', 'historyposts', 'onlinerecord', 'userstats', 'diytemplatenameforum'),
    'forumdisplay'    => array('smilies', 'announcements_forum', 'globalstick', 'forums',
            'onlinelist', 'forumstick', 'threadtable_info', 'threadtableids', 'stamps', 'diytemplatenameforum'),
    'viewthread'    => array('smilies', 'smileytypes', 'forums', 'usergroups',
            'stamps', 'bbcodes', 'smilies',    'custominfo', 'groupicon', 'stamps',
            'threadtableids', 'threadtable_info', 'posttable_info', 'diytemplatenameforum'),
    'redirect'    => array('threadtableids', 'threadtable_info', 'posttable_info'),
    'post'        => array('bbcodes_display', 'bbcodes', 'smileycodes', 'smilies', 'smileytypes',
            'domainwhitelist', 'albumcategory'),
    'space'        => array('fields_required', 'fields_optional', 'custominfo'),
    'group'        => array('grouptype', 'diytemplatenamegroup'),
);

定义了2个变量

$modarray 模型的种类， 'ajax','announcement','attachment'...

$modcachelist 模型的缓存列表 index 包含'announcements', 'onlinelist', 'forumlinks'   //还不太理解为何这样。

 

$mod = !in_array(C::app()->var['mod'], $modarray) ? 'index' : C::app()->var['mod'];

语法没问题， in_arrary(), $mod为 首页,index, 否则 模块为 。

 

 

 

$mod = !in_array(C::app()->var['mod'], $modarray) ? 'index' : C::app()->var['mod'];

define('CURMODULE', $mod);
$cachelist = array();
if(isset($modcachelist[CURMODULE])) {
    $cachelist = $modcachelist[CURMODULE];

    $cachelist[] = 'plugin';
    $cachelist[] = 'pluginlanguage_system';
}
if(C::app()->var['mod'] == 'group') {
    $_G['basescript'] = 'group';
}

C::app()->cachelist = $cachelist;
C::app()->init();


loadforum();


set_rssauth();


runhooks();



$navtitle = str_replace('{bbname}', $_G['setting']['bbname'], $_G['setting']['seotitle']['forum']);
$_G['setting']['threadhidethreshold'] = 1;
require DISCUZ_ROOT.'./source/module/forum/forum_'.$mod.'.php';
