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
我要评论
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("\n", "<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 ;
