include_once libfile('function/post');这段代码引入,因为你messagecutstr()函数是在“function/post”中定义的!
function messagecutstr($str, $length = 0, $dot = ' ...') { global $_G; $str = messagesafeclear($str); $sppos = strpos($str, chr(0).chr(0).chr(0)); if($sppos !== false) { $str = substr($str, 0, $sppos); } $language = lang('forum/misc'); loadcache(array('bbcodes_display', 'bbcodes', 'smileycodes', 'smilies', 'smileytypes', 'domainwhitelist')); $bbcodes = 'b|i|u|p|color|size|font|align|list|indent|float'; $bbcodesclear = 'email|code|free|table|tr|td|img|swf|flash|attach|media|audio|groupid|payto'.($_G['cache']['bbcodes_display'][$_G['groupid']] ? '|'.implode('|', array_keys($_G['cache']['bbcodes_display'][$_G['groupid']])) : ''); $str = strip_tags(preg_replace(array( "/[hide=?d*](.*?)[/hide]/is", "/[quote](.*?)[/quote]/si", $language['post_edit_regexp'], "/[url=?.*?](.+?)[/url]/si", "/[($bbcodesclear)=?.*?].+?[/\1]/si", "/[($bbcodes)=?.*?]/i", "/[/($bbcodes)]/i", ), array( "[b]$language[post_hidden][/b]", '', '', '\1', '', '', '', ), $str)); if($length) { $str = cutstr($str, $length, $dot); } $str = preg_replace($_G['cache']['smilies']['searcharray'], '', $str); if($_G['setting']['plugins']['func'][HOOKTYPE]['discuzcode']) { $_G['discuzcodemessage'] = & $str; $param = func_get_args(); hookscript('discuzcode', 'global', 'funcs', array('param' => $param, 'caller' => 'messagecutstr'), 'discuzcode'); } return trim($str);}复制代码
