//定义空字符串，容纳回复评论的id var ids=""; $(".hf").click(function(){ ids = $(this).attr("ids"); //将评论的id重新赋值 // alert((ids)); $('#mM').modal('show'); }) //将回复评论写进数据库 $("#tjhf").click(function(){ var hfnr = $(".hfpl").val(); // alert(hfnr); // alert(ids); $.ajax({ url:"hf-cl.php", data:{hfnr:hfnr,ids:ids}, type:"POST", dataType:"TEXT", success:function(data){ alert("回复成功！"); window.location.href="main.php" ; } }); })
hf-cl.php页面
<?phprequire "../DB.class.php"; $db = new DB(); session_start(); $uid = $_SESSION["uid"]; $hfnr = $_POST["hfnr"]; $cid = $_POST["ids"]; $time = date("Y-m-d H:i:s", time()); $sql = "insert into qqhuifu values ('','{$cid}','{$uid}','{$hfnr}','{$time}')"; $db->query($sql,0); ?>
查看qqhuifu表，是不是多了一行呢？
3、将回复内容读出：
<div> <!--取一次回复--> <?php $sql = "select * from qqhuifu where cid in (select cid from qqpinglun)"; $arr = $db->query($sql); foreach($arr as $a) { $sql = "select * from qqpinglun where cid='{$a[1]}'"; $arr2 = $db->query($sql); foreach($arr2 as $n) { //取评论动态的姓名 $sql = "select name from qqusers where uid='{$a[2]}'"; $name = $db->strquery($sql); //若果是登录者评论则显示“我” if($a[2]==$uid) { $name ="我"; } //获取被回复评论的姓名 $sql = "select name from qqusers where uid=(select uid from qqpinglun where cid='{$a[1]}')"; $bpl = $db->strquery($sql); echo "<div><span>{$name}</span>回复<span>{$bpl}</span>的评论:{$n[3]}<div> <div>{$a[3]}</div> <div>回复时间：{$a[4]}</div> <div><button ids ='{$a[0]}'>回复 </button><span><a href='schf-cl.php?code={$a[0]}'>删除回复</a></span></div>"; } } ?> </div>
回复内容已经显示了：
第三步：删除
1、删除动态：（含评论和回复）
scdt-cl.php
<?php $code = $_GET["code"]; require "../DB.class.php"; $db = new DB(); $sql = "delete from qqdongtai where dtid='{$code}'"; $db->query($sql,0); $sql2 = "delete from qqpinglun where dtid='{$code}'"; $db->query($sql2,0); $sql3 = "delete from qqhuifu where cid=(select cid from qqpinglun where dtid='{$code}')"; $db->query($sql3,0); header("location:main.php"); ?>
2、删除评论：（含回复）
scpl-cl.php
<?php $code = $_GET["code"]; require "../DB.class.php"; $db = new DB(); $sql2 = "delete from qqpinglun where cid='{$code}'"; $db->query($sql2,0); $sql3 = "delete from qqhuifu where cid='{$code}'"; $db->query($sql3,0); header("location:main.php"); ?>
3、删除回复：（只自己）
schf-cl.php
<?php $code = $_GET["code"]; require "../DB.class.php"; $db = new DB(); $sql2 = "delete from qqpinglun where cid='{$code}'"; $db->query($sql2,0); $sql3 = "delete from qqhuifu where cid='{$code}'"; $db->query($sql3,0); header("location:main.php"); ?>
关于删除就不依次试了~~~注意包含关系就好了
