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	    $data['lastfloor'] = "<div class="\"cmt_old\"">".$lastFloor.
10	            "<div class="\"cmt_old_head\"">".
11	            "<div class="\"cmt_old_info\""><span class="\"cmt_sitename\"">EXCMS</span>".
12	            "<span class="\"cmt_old_author\"">{$replyInfo['area']}网友(".ipformat($replyInfo['ip']).") 的原贴：</span></div>".
13	            "<span class="\"cmt_old_floor\"">{$replyInfo['floor']}</span></div>".
14	            "<p class="\"cmt_old_message\"">{$replyInfo['content']}</p></div>";
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));

代码修改[ ]

页面参数可以自由修改，根据模板的需要来增加和修改页面参数。模板中可自由调用页面的参数，例如：{$_PAGE.title}显示页面标题。
