PHP仿qq空间或朋友圈发布动态、评论动态、回复评论、删除动态或评论的功能（上）
时间：2017-06-10对应的main-cl.php页面：
<!--?php
session_start();
$uid = $_SESSION["uid"];
$dt = $_POST["dt"];
$date = date ("Y-m-d H:i:s");
require "../DB.class.php";
$db = new DB();
$sql = "insert into qqdongtai values ('','{$uid}','{$dt}','{$date}')";
$db--->query($sql,0);
$sql = "select * from qqdongtai where uid='{$uid}' or uid in (select uid from qqfriends where fname =(select name from qqusers where uid='{$uid}'))";
//echo $sql;
$arr = $db->strquery($sql);
echo $arr;
?>
然后：
//刷新页面时将内容读取出来，并按发表时间读出来
$.ajax({
url:"sx-cl.php",
dataType:"TEXT",
success:function(data){
var hang = data.trim().split("|");
var str="";
for(var i=0;i<hang.length;i++) {="" var="" lie="hang[i].split("^");" str="str" +="" "<div="" class="a"><span class="xm">"+lie[1]+"</span>发表动态：<div class="b">"+lie[2]+"<p></p><div class="c">发表动态时间："+lie[3]+"</div>";
str =str+"<div id="d"><button class="btn btn-primary" data-toggle="modal" data-target="#myModal">评论</button><span><a href="del.php?code=" rel="external nofollow" +lie[0]+"">删除动态</a></span></div>";
}
$("#nr").html(str);
}
});
</div></hang.length;i++)>
sx-cl.php页面：
<!--?php
session_start();
$uid = $_SESSION["uid"];
$date = date ("Y-m-d H:i:s");
require "../DB.class.php";
$db = new DB();
//选取该用户和该用户好友的动态，并按时间顺训读出
$sql = "select * from qqdongtai where uid='{$uid}' or uid in (select uid from qqfriends where fname =(select name from qqusers where uid='{$uid}')) order by time desc";
//echo $sql;
$arr = $db--->strquery($sql);
echo $arr;
?>
由上面可知：登录用户是lisi，由好友表可以知道，lisi的好友只有zhangsan和zhaoliu,那么显示的动态只能有lisi,zhangsan,和zhaoliu的。现在看一下效果及数据库~~~~
第四步：用bootstrap添加模态框用来评论动态
（1）引入文件：
<!--引入bootstrap的css文件--> <link type="text/css" rel="stylesheet" href="../bootstrap-3.3.7-dist/css/bootstrap.min.css" rel="external nofollow" rel="external nofollow" > <!--引入js包--> <!--引入bootstrap的js文件-->
（2）用模态框做评论效果：
<!-- 评论模态框（Modal） -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title" id="myModalLabel">评论</h4>
</div>
<textarea class="modal-body" cols="80px"></textarea>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">关闭</button>
<button type="button" class="btn btn-primary qdhf">确定</button>
</div>
</div><!-- /.modal-content -->
</div><!-- /.modal -->
</div>
实现效果：（样式比较简陋）
点击“评论”：
到这一步基本就能实现动态的发布和显示好友动态了~~~~未完待续----评论和评论回复见下一篇随笔~~~

织梦dedecms后台增加logo上传功能用过dedecms的朋友都知道，织梦cms后台系统基本参数里是无法直接上传图片的，我们更换logo图只能到ftp里替换，非常的不方便
