PHP+Mysql无刷新问答评论系统(源码)

自己写的一个评论系统源码分享给大家，包括有表情，还有评论机制。用户名是随机的

针对某一篇文章进行评论

function subcomment() {

  $data['uid'] = getUserid();

  $data['mtype'] = I("post.mtype", 0, 'int');

  if ($data['uid'] == '') {

    echo json_encode(array("code" => -1));

  } else {

    $content = addslashes(str_replace(" ", "<br />", $_POST['content']));

    $data['tid'] = I("post.id", 0, 'int'); //文章id

    if (strlen(preg_replace('/[ [^)]+? ]/x', '', $content)) < 10) {

      echo json_encode(array("code" => "short than 10", "error" => "评论的内容不能少于10个字符。"));

      exit;

    }

    if (C("DB_PWD") != '') {

      if (time() - session("comment_time") < 60 && session("comment_time") > 0) {//2分钟以后发布

        echo json_encode(array("code" => "fast", "error" => "您提交评论的速度太快了，请稍后再发表评论。"));

        exit;

      }

    }

    $data['pid'] = I("post.pid", 0, 'int');

    $data['pid_sub'] = I("post.pid_sub", 0, 'int');

    $lyid = $data['pid_sub'] > 0 ? $data['pid_sub'] : $data['pid'];

    if ($lyid > 0) {

      $lyinfo = M("comment")->field("uid")->where("id='" . $lyid . "'")->find();

      $data['touid'] = $lyinfo['uid'];

    } else {

      $data['touid'] = 2;

    }

    $data['addtime'] = time();

    $emots = getTableFile("emot");

    foreach ($emots as $v) {

      $content = str_replace("[" . $v['name'] . "]", "<img alt='" . $v['name'] . "' src='" . __APP__ . "/Public/emot/" . ($v['id'] - 1) . ".gif'>", $content);

    }

    $data['content'] = addslashes($content);

    $info = M("comment")->field("id")->where("content='" . $data['content'] . "'")->find();

    if ($info['id']) {

      echo json_encode(array("code" => "comment_repeat", "error" => "检测到重复评论，您似乎提交过这条评论了"));

      exit;

    }

    $lastid = M("comment")->add($data);

    $points_comment = 20;

    if ($lastid > 0) {

      $day_start = strtotime(date("Y-m-d"));

      $day_end = $day_start + 3600 * 24;

      $comment_num_day = M("comment")->where("uid = " . $data['uid'] . " AND addtime between " . $day_start . " AND " . $day_end . "")->count();

      if ($comment_num_day <= 5) { //少于5条每天，则添加积分

//          addPoints("comment", $points_comment, $data['uid'], "评论获得" . $points_comment . "积分", 5, 1);

      }

//        addMessage('comment', $data['tid'], $data['pid'], $data['mtype'], $data['touid'], $content);

    }

    session("comment_time", time());

    echo json_encode(array("code" => 200, "comment" => $content, "points" => $points_comment));

  }

}

根据分页参数获取对应评论列表

									function comments() { 

									  $id = I("get.id", 0, 'int'); 

									  $mtype = I("get.mtype", 1, 'int'); 

									  $page = I("get.page", 1, "int"); 

									  $totalnum = I("get.totalnum", 1, "int"); 

									  $start = 10 * ($page - 1); 

									  $sql = "tid = " . $id . " AND pid = 0"; 

									  $comments = M("comment")->field("id,uid,content,addtime")->where($sql)->order("id DESC")->limit($start . ",10")->select(); 

									//    echo M("comment")->getlastsql(); 

									  foreach ($comments as $k => $v) { 

									    $comments[$k]['sub'] = M("comment")->field("id,uid,content,pid_sub")->where("tid = " . $id . " AND pid = " . $v['id'] . "")->order("id ASC")->select(); 

									  } 

									  $this->assign("id", $id); 

									  $this->assign("mtype", $mtype); 

									  $this->assign("comments", $comments); 

									  $this->assign("comments_num", $totalnum - ($page - 1) * 10); 

									  $this->display(); 

									}

切换评论分页

									if ($("#detail-page").length > 0) { 

									  var id = $("#detail-page").attr("data-id"); 

									  var mtype = $("#detail-page").attr("data-mtype"); 

									  var totalnum = $("#detail-page").attr("data-totalnum"); 

									  $("#detail-page").children("a").click(function() { 

									    var page = parseInt($(this).attr("data-page")); 

									    $("#detail-page").children("a").removeClass("current"); 

									    $("#detail-page").children("a").eq(page - 1).addClass("current"); 

									    $("#comment_list").html("<div style='padding:20px 0;text-align:center;'><img src='" + site_url + "Public/images/loading.gif'></div>"); 

									    $.get(getUrl("Box/comments"), { 

									      page: page, 

									      id: id, 

									      totalnum: totalnum, 

									      mtype: mtype 

									    }, 

									    function(data) { 

									      $("#comment_list").html(data) 

									    }) 

									  }) 

									}

评论表和表情表已放在压缩包里

									CREATE TABLE IF NOT EXISTS `sucai_comment` ( 

									 `id` int(11) NOT NULL AUTO_INCREMENT, 

									 `uid` int(11) NOT NULL, 

									 `touid` int(11) DEFAULT '0', 

									 `pid_sub` int(11) DEFAULT '0', 

									 `tid` int(11) NOT NULL, 

									 `pid` int(11) DEFAULT '0', 

									 `mtype` tinyint(1) NOT NULL, 

									 `content` text NOT NULL, 

									 `addtime` int(10) NOT NULL, 

									 PRIMARY KEY (`id`) 

									) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=5560 ;
