代码说明
- 检查验证码是否开启验证码并判断验证码是否正确。
1 if (isset ( $EXCMS['comment']['checkcodes'] ) && $EXCMS['comment'] ['checkcodes'] == 1 && !excms_func_checkcode_check($params
['checkcodes'])) {
2 showMessage('验证码错误');
3 }
- 根据内容ID获取内容详细信息，如果内容ID为空会报缺少内空ID异常。
1 //文章信息 2 excms_import ( 'EXCMS.content.Content' ); 3 $c = new Content ( ); 4 $cInfo = $c->getById ( $contentid );
- 根据栏目ID获取栏目详细信息，如果栏目ID为空会报缺少栏目ID异常。
1 //栏目信息 2 excms_import ( 'EXCMS.channel.Channel' ); 3 $channel = new Channel ( ); 4 $channelInfo = $channel->getById ( $cInfo['channelid'] );
- 验证当前内容是否允许评论并且是否需要登陆。
01 if (! ($channelInfo ['comment'] > 0)) {
02 showMessage('文章不允许评论(栏目)');
03 }
04 if (!$cInfo ['comment']) {
05 showMessage('文章不允许评论(文章)');
06 }
07 if (! ($moduleInfo ['disabled'])) {
08 showMessage('评论已经禁用');
09 }
10 if (! ($EXCMS['comment'] ['allow_guest'] > 0) && ! ($_SESSION ['memberid'] > 0)) {
11 showMessage('请登录后再评论');
12 }
- 检查是否是匿名评论。
1 $data ['memberid'] = $_SESSION ['memberid'] > 0 ? $_SESSION ['memberid'] : 0;
2 $data ['membername'] = $_SESSION ['membername'] ? $_SESSION ['membername'] : '游客';
3
4 if ($EXCMS['comment'] ['anonymous'] && $params ['anonymous']) { //匿名评论
5 $data ['memberid'] = 0;
6 $data ['membername'] = '游客';
7 }
- 检查是否允许隐藏IP和所在位置，可以通过评论的后台管理设置这些配置信息。
01 $ip = $_SERVER ["REMOTE_ADDR"];
02 if($EXCMS['comment']['allow_hide_ip'] && !$params['allow_hide_ip']){ //是否允许隐藏IP
03 $data ['ip'] = $ip;
04 }
05 if($EXCMS['comment']['allow_hide_posion'] && !$params['allow_hide_posion']){ //是否允许隐藏所在位置
06 include_once(DOCUMENT_ROOT.'admin/Modules/Plugins/Ipquery/IpLocation.class.php'); //引入 IplLocation类
07 $obj = new IpLocation(); //创建IpLocation对像
08 $iparea = $obj->getlocation($ip); //根据IP地址获取所有地区
09 $data ['area'] = isset($iparea ['country']) && !empty($iparea ['country']) ? $iparea ['country'] : $ip; //所在地区
10 }
- 把评论信息存入在$data数组中。
1 $data ['itemid'] = $contentid; //内容ID(必须) 2 $data ['channelid'] = $cInfo ['channelid']; //栏目ID(必须) 3 $data ['channelcross'] = $cInfo ['channelcross']; //交叉栏目ID 4 $data ['createddate'] = time (); //评论时间 5 $data['support'] = 0; //支持数 6 $data['against'] = 0; //反对数
- 如果当前回复的是评论，根据评论ID获取评论相关信息，然后存后到最上层内容中。
01 $replyid = (int)$params['reply'];
02 if($replyid){
03 $replyInfo = $comment->getById($replyid);
04 $data ['replyid'] = $replyid;
05 $data ['floor'] = $replyInfo['floor'] + 1;
06
07 $lastFloor = $replyInfo['floor'] > 1 ? $replyInfo['lastfloor'] : ;
08 //id=\"commentid_{\$replyid}_{$replyInfo['floor']}_head\"
09 $data['lastfloor'] = "".$lastFloor.
10 "".
11 "EXCMS".
12 "{$replyInfo['area']}网友(".ipformat($replyInfo['ip']).") 的原贴：".
13 "{$replyInfo['floor']}".
14 "{$replyInfo['content']}
";
15 }else{
16 $data ['replyid'] = 0;
17 $data ['floor'] = 1;
18 $data['lastfloor'] = ;
19 }
- 保存评论信息并跳转到当前内容评论列表。
1 $data ['content'] = htmlspecialchars($_POST['commenttext']);
2 $comment->insert($data,"content");
3 header("Location:comment.php?contentid=".icanid($contentid));
