*检查验证码是否开启验证码并判断验证码是否正确。

2	    showMessage('验证码错误');
3	}
</pre>

*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。
<pre>
1	//文章信息
2	excms_import ( 'EXCMS.content.Content' );
3	$c = new Content ( );
4	$cInfo = $c->getById ( $contentid );
</pre>

<pre>
1	//栏目信息
2	excms_import ( 'EXCMS.channel.Channel' );
3	$channel = new Channel ( );
4	$channelInfo = $channel->getById ( $cInfo['channelid'] );
</pre>

*验证当前内容是否允许评论并且是否需要登陆。
<pre>

</pre>

*保存评论信息并跳转到当前内容评论列表。
<pre>
1	$data ['content'] = htmlspecialchars($_POST['commenttext']);
2	$comment->insert($data,"content");
3	header("Location:comment.php?contentid=".icanid($contentid));
</pre>

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。
