主要目的是还原帖子内的附件，图片等。
代码如下：
- <?php
- if ( !defined( 'IN_DISCUZ' ) ) {
- exit( 'Access Denied' );
- }
- // $tid 为帖子ID
- // 在广播 测试过 只显示一条的信息
- $thread_info = DB::fetch_first( "select a.`tid`, a.`authorid`, a.`author`, a.`dateline`, a.`subject`, b.`message` from " . DB::table( 'forum_thread' ) . " as a, " . DB::table( 'forum_post' ) . " as b where a.tid=$tid and a.tid=b.tid and b.first=1 order by pid desc limit 1" );
- require_once libfile( 'function/discuzcode' );
- $thread_info[ 'dateline' ] = date( "Y-m-d H:i:s", $thread_info[ 'dateline' ] );
- $thread_info[ 'message' ] = discuzcode( $thread_info[ 'message' ] );
- if ( preg_match_all( "/\[attach\](\d+)\[\/attach\]/i", $thread_info[ 'message' ], $matchaids ) ) {
- $attach_ids = $matchaids[ 1 ];
- }
- $attach_list = array();
- foreach ( $attach_ids as $aid ) {
- $find = "/\[attach\]$aid\[\/attach\]/i";
- $thread_info[ 'message' ] = preg_replace( $find, get_lw_attach_path( $aid ), $thread_info[ 'message' ], 1 );
- $thread_info[ 'message' ] = preg_replace( $find, '', $thread_info[ 'message' ] );
- }
- function get_lw_attach_path( $aid ) {
- global $_G;
- $return = $filename = '';
- if ( $attach = C::t( 'forum_attachment_n' )->fetch( 'aid:' . $aid, $aid, array( 1, -1 ) ) ) {
- return get_lw_attach_path_str( $attach );
- }
- return $filename;
- }
- function get_lw_attach_path_str( $attach ) {
- global $_G;
- if ( !$attach[ 'isimage' ] ) {
- return '<a href="' . $_G[ 'siteurl' ] . 'forum.php?mod=attachment&aid=' . aidencode( $attach[ 'aid' ] ) . '">' . $attach[ 'filename' ] . '</a>';
- }
- if ( $attach[ 'remote' ] ) {
- $imgurl = $_G[ 'setting' ][ 'ftp' ][ 'attachurl' ] . 'forum/' . $attach[ 'attachment' ];
- return '<img onclick="viewimage(this);" src="' . $imgurl . '" />';
- } else {
- if ( preg_match( '/^(?!http:)/', $attach[ 'url' ] ) ) {
- $attach[ 'url' ] = $_G[ 'siteurl' ] . 'data/attachment/forum/' . $attach[ 'url' ];
- }
- $imgurl = $attach[ 'url' ] . $attach[ 'attachment' ] . ( $_G[ 'gp_width' ] ? '&width=' . $_G[ 'gp_width' ] : '' ) . ( $_G[ 'gp_height' ] ? '&height=' . $_G[ 'gp_height' ] : '' );
- return '<a href="' . $imgurl . '" target="_blank"><img height="320" width="320" src="' . $imgurl . '" /></a>';
- }
- }
- echo $thread_info[ 'message' ];

discuz帖子内容还原HTML
进过测试，只能还原一个ID帖子的内容，可能是我哪里没有整对。
