discuz修改论坛的rss为全文输出的方法

找到文件： \source\module\forum\forum_rss.php

找到位置：

if($attachfile) {
                         if($attachremote) {
                              $filename = $_G['setting']['ftp']['attachurl'].'forum/'.$attachfile;
                         } else {
                              $filename = (!strstr($_G['setting']['attachurl'], '://') ? $_G['siteurl'] : '').$_G['setting']['attachurl'].'forum/'.$attachfile;
                         }
                    }

在其下方加入这样一段话：

$fdata = DB::fetch_first("SELECT * FROM ".DB::table('forum_post')." WHERE tid = '$thread[tid]' and first = 1");

将其下方的这段话：

echo      "    <item>\n".
                         "      <title>".$thread['subject']."</title>\n".
                         "      <link>$_G[siteurl]".($trewriteflag ? rewriteoutput('forum_viewthread', 1, '', $thread['tid']) : "forum.php?mod=viewthread&tid=$thread[tid]")."</link>\n".
                         "      <description><![CDATA[".dhtmlspecialchars($thread['description'])."]]></description>\n".
                         "      <category>".dhtmlspecialchars($thread['forum'])."</category>\n".
                         "      <author>".dhtmlspecialchars($thread['author'])."</author>\n".
                         ($attachfile ? '<enclosure url="'.$filename.'" length="'.$attachsize.'" type="image/jpeg" />' : '').
                         "      <pubDate>".gmdate('r', $thread['dateline'])."</pubDate>\n".
                         "    </item>\n";

修改为：

echo      "    <item>\n".
                         "      <title>".$thread['subject']."</title>\n".
                         "      <link>$_G[siteurl]".($trewriteflag ? rewriteoutput('forum_viewthread', 1, '', $thread['tid']) : "forum.php?mod=viewthread&tid=$thread[tid]")."</link>\n".
                         "      <description><![CDATA[".dhtmlspecialchars($fdata['message'])."]]></description>\n".
                         "      <category>".dhtmlspecialchars($thread['forum'])."</category>\n".
                         "      <author>".dhtmlspecialchars($thread['author'])."</author>\n".
                         ($attachfile ? '<enclosure url="'.$filename.'" length="'.$attachsize.'" type="image/jpeg" />' : '').
                         "      <pubDate>".gmdate('r', $thread['dateline'])."</pubDate>\n".
                         "    </item>\n";

然后刷新即可看到效果
