php怎么批量删除表格内容?
php *** 作表格数据【含批量删除】
效果图:
list_pl.php:
<?php $con = mysqli_connect('localhost','root','123456','test'); mysqli_set_charset($con,'utf8'); if(!$con){ die('Could not connect:' . mysql_error($con)); } $sql = "select * from login"; $result = mysqli_query($con,$sql); $rows = array(); while($row = mysqli_fetch_assoc($result)){ $rows[] = $row; } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>无标题文档</title> <style> *{padding:0;margin:0;} .pd-lr{padding: 5px 20px} </style> </head> <body> <table width="100%" border="1" cellpadding="0" cellspacing="0"> <thead> <tr> <td width="30"> 全选:<input id="checkAll" type="checkbox"> </td> <td width="30">id</td> <td width="30">用户名</td> <td width="30">密码</td> <td width="30">邮箱</td> <td width="40"> *** 作</td> <td width="30">提交时间</td> </tr> </thead> <tbody> <?php foreach($rows as $k => $v) { ?> <tr> <td><input type="checkbox" name="box" value="<?= $v['id'] ?>" class="checkOne"></td> <td><?php echo $v['id'];?></td> <td><?php echo $v['username'];?></td> <td><?php echo $v['password'];?></td> <td><?php echo $v['email'];?></td> <td> <a href="javascript:confirm_delete('shanchu.php?sno=<?php echo $v['id'];?>')">删除</a> <a href='xiugai.php?sno=<?php echo $v['id'];?>'>修改</a> </td> <td><?php echo $v['CreateTime'];?></td> </tr> <?php } ?> </tbody> </table> <p class="pd-lr"> <button style="float:left;">批量删除</button> <!-- 数据表的总条数 --> <p style="float:right;display:inline-block;">总共<span><?php $sql2 = "SELECT COUNT(*) FROM login"; //获取某一张表的所有数据 $all_value = $con->query($sql2); while ($nums=$all_value->fetch_assoc()) { //输出每一行数据 echo ($nums['COUNT(*)']); //获取数据库总条数 } ?></span>条</p> </p> <script src="./jquery-3.2.1.min.js"></script> <script> // 单项删除 function confirm_delete(url){ if(confirm('您确定要执行删除 *** 作?')){ window.location.href=url; }else{ return false; } } // 全选,反选 $("#checkAll").on('change', function () { if ($(this).is(":checked")) { // 全选 $(".checkOne").prop("checked",true); } else { // 反选 $(".checkOne").prop("checked",false); } }); // 批量删除 $('button').click(function(){ var ids=$('.checkOne:checkbox'); var str=''; var count=0; for(var i=0;i<ids.length;i++){ if(ids.eq(i).is(':checked')){ str+=','+ids.eq(i).val(); count++; } } var str=str.substr(1); if(confirm('你确定要删除这'+count+'条数据吗?')){ //获取id后删除 $.ajax({ type:'GET', url:'adminDel.php', // contentType: "application/json;charset=utf-8", data:{'str':str}, // dataType:'json',//用get方法时不指定这项(可能是json数据不够严谨) success:function(res){ if(res>0){ for(var i=ids.length-1;i>=0;i--){ if(ids.eq(i).is(':checked')){ ids.eq(i).parent().parent().remove(); } } } alert('删除成功!'); window.location.reload(); }, error:function(data){ console.log("数据加载失败",data); } }) } return false; }); </script> </body> </html>
shanchu.php(单项删除也可以直接填adminDel.php的路径):
<?php $aaa = $_GET ["sno"]; //删除方式使用的get,照旧 $db = new mysqli("localhost","root","123456","test"); $sql = "delete from login WHERE id='{$aaa}'"; if($db->query($sql)){ // header("location:list.php"); echo "<script>alert('删除成功!');window.location.href='list.php'</script>" ; }else{ echo "删除失败"; } ?>
xiugai.php(修改页面):
<html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>无标题文档</title> </head> <body> <h1>修改</h1> <?php $sno = $_GET{"sno"}; $db = new mysqli("localhost","root","123456","test"); $sql = "select * from login WHERE id='{$sno}'"; $r = $db->query($sql); $arr = $r->fetch_row(); ?> <form action="update.php" method="post"> <p>id:<input type="text" name="id" value="<?php echo $arr[0]; ?>"/></p> <p>用户名:<input type="text" name="username" value="<?php echo $arr[1]; ?>"/></p> <p>密码:<input type="text" name="password" value="<?php echo $arr[2]; ?>"/></p> <p>邮箱:<input type="text" name="email" value="<?php echo $arr[4]; ?>"/></p> </p> <p><input type="submit" value="修改完毕"/></p> </form> </body> </html>
xiugai.php更新页面还可以这样写:
<?php //创建连接:四个参数分别为 服务器地址、用户名、密码、数据库名 $conn = mysqli_connect("localhost","root","123456","test"); $sno = $_GET{"sno"}; //查询数据的sql语句 $sql = "select * from login WHERE id='{$sno}'"; //执行语句接收返回值 $result = mysqli_query($conn,$sql); //输错查询的数据 while ($row = mysqli_fetch_array($result)){?> <style type="text/css"> .list{margin: 0 auto;} .list p{font-size: 1rem;padding: 5px 0;} .list p span{display: inline-block;width: 100px;} .list p input{padding: 5px 0;outline:none;border: 1px solid #ccc;border-radius: 4px;-webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, .075);box-shadow: inset 0 1px 1px rgba(0, 0, 0, .075);-webkit-transition: border-color ease-in-out .15s, -webkit-box-shadow ease-in-out .15s;-o-transition: border-color ease-in-out .15s, box-shadow ease-in-out .15s;transition: border-color ease-in-out .15s, box-shadow ease-in-out .15s;} .list p input:focus {border-color: #66afe9;outline: 0;-webkit-box-shadow: inset 0 1px 1px rgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6);box-shadow: inset 0 1px 1px rgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6);} .list .up_btn input{padding: 5px 10px;font-size: 1rem;border: 1px solid #2285ed;background-color: #FFF;} .list .up_btn input:hover{background-color: #2285ed;color: #fff;} .tran-b{-webkit-transition: all ease-out .5s;-o-transition: all ease-out .5s;transition: all ease-out .5s;} </style> <form action="./update.php" method="post" class="list"> <p><span style="color: #2285ed;">id:<input type="hidden" value="<?php echo $row['id'];?>" name="id" /><?php echo $row['id'];?></span></p> <p><span>用户名:</span><input type="text" name="username" value="<?php echo $row['username'];?>" /></p> <p><span>密码:</span><input type="text" name="password" value="<?php echo $row['password'];?>" /></p> <p><span>邮箱:</span><input type="text" name="email" value="<?php echo $row['email'];?>" /></p> </p> <p class="up_btn"><input type="submit" value="修改完毕" class="tran-b"/></p> </form> <?php }?>
update.php(更新页面) :
<?php error_reporting(E_ALL ^ E_NOTICE); $id = $_POST["id"]; $username = $_POST["username"]; $password = $_POST["password"]; $email = $_POST["email"]; $db = new mysqli("localhost","root","123456","test"); $sql = "update login set username='{$username}',password='{$password}',email='{$email}' WHERE id='{$id}'"; if($db->query($sql)){ // header("location:list.php"); echo "<script>alert('修改成功!');window.location.href='list_pl.php'</script>" ; }else{ echo "修改失败"; } ?>
adminDel.php(批量删除页面):
<?php error_reporting(E_ALL ^ E_NOTICE); // header('content-type:text/html;charset=utf-8'); // header('Content-type: application/json;charset=utf-8'); $str=$_GET['str']; // echo $str; $link = mysqli_connect( 'localhost' , 'root' , '123456' , 'test' ); // mysqli_query($link,'set names utf8'); $sql='delete from login where id in ('.$str.')'; mysqli_query($link,$sql); ?>
遇到的问题:
ajax提交数据报错,我是在本地运行的,参考:https://ask.csdn.net/questions/325174把dataType:'json',改成dataType:'text',就可以运行了,或者把dataType:'json'删掉也行。
