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));
- }
- }
