Code analysis and study of discuz (4) Forum entrance file, discuz forum entrance

is just a rough analysis of the execution process, mainly to obtain the value of the mod parameter and load it according to the value Controller, the controller position is specified on the last line.

1) Define the application name and load two necessary files

<span>define</span>('APPTYPEID', 2<span>);
</span><span>define</span>('CURSCRIPT', 'forum'<span>);

</span><span>require</span> './source/class/class_core.php';<span>//</span><span>核心类</span>
<span>require</span> './source/function/function_forum.php';<span>//</span><span>论坛函数库</span>

2) The modarray array limits the mod value range

<span>$modarray</span> = <span>array</span>('ajax','announcement','attachment','forumdisplay',
    'group','image','index','medal','misc','modcp','notice','post','redirect',
    'relatekw','relatethread','rss','topicadmin','trade','viewthread','tag','collection','guide'<span>
);
</span><span>//</span><span>模块缓存列表,各个子数组分别表示各个模块要缓存的缓存项</span>
<span>$modcachelist</span> = <span>array</span><span>(
    </span>'index'        => <span>array</span>('announcements', 'onlinelist', 'forumlinks',
            'heats', 'historyposts', 'onlinerecord', 'userstats', 'diytemplatenameforum'),
    'forumdisplay'    => <span>array</span>('smilies', 'announcements_forum', 'globalstick', 'forums',
            'onlinelist', 'forumstick', 'threadtable_info', 'threadtableids', 'stamps', 'diytemplatenameforum'),
    'viewthread'    => <span>array</span>('smilies', 'smileytypes', 'forums', 'usergroups',
            'stamps', 'bbcodes', 'smilies',    'custominfo', 'groupicon', 'stamps',
            'threadtableids', 'threadtable_info', 'posttable_info', 'diytemplatenameforum'),
    'redirect'    => <span>array</span>('threadtableids', 'threadtable_info', 'posttable_info'),
    'post'        => <span>array</span>('bbcodes_display', 'bbcodes', 'smileycodes', 'smilies', 'smileytypes',
            'domainwhitelist', 'albumcategory'),
    'space'        => <span>array</span>('fields_required', 'fields_optional', 'custominfo'),
    'group'        => <span>array</span>('grouptype', 'diytemplatenamegroup'),<span>
);</span>

3) If the mod parameter is empty or illegal, the expression will be true, resulting in a value of index

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

4) Initialization

<span>define</span>('CURMODULE', <span>$mod</span><span>);
</span><span>//</span><span>var_dump(CURMODULE);</span>
<span>$cachelist</span> = <span>array</span><span>();
</span><span>if</span>(<span>isset</span>(<span>$modcachelist</span>[CURMODULE])) {<span>//</span><span>如果当前缓存项存在的话，</span>
    <span>$cachelist</span> = <span>$modcachelist</span>[CURMODULE];<span>//</span><span>获取当前缓存组的缓存列表项</span>

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

C</span>::app()->cachelist = <span>$cachelist</span><span>;
C</span>::app()->init();<span>//</span><span>初始化</span>
<span>

loadforum();


set_rssauth();


runhooks();</span>

5) Load controller

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