本文实例为大家分享了php批量删除操作的具体代码,供大家参考,具体内容如下
1.批量删除页面 piliangcaozuo.php
<body> <form action=shanchu.php method=post> <table width=100% border=1 cellpadding=0 cellspacing=0> <tr> <td><input type=checkbox name=qx onclick=quanxuan(this)/>代号</td> <td>名称</td> </tr> <?php requireDBDA.class1.php; $db = new DBDA(); $sql = select * from nation; $arr = $db->query($sql); foreach($arr as $v) { echo <tr> <td><input type=checkbox name=ck[] class=ck value={$v[0]}/>{$v[0]}</td> <td>{$v[1]}</td> </tr>; } ?> </table> <input type=submit value=批量删除 /> </form> </body> <script type=text/javascript> function quanxuan(qx) { var ck=document.getElementsByClassName(ck); if(qx.checked) { for(var i=0;i<ck.length;i++) { ck[i].setAttribute(checked,checked); } } else { for(var i=0;i<ck.length;i++) { ck[i].removeAttribute(checked); } } } </script> </html>
引用的封装类 DBDA.class1.php
<?php class DBDA { public $host = localhost; public $uid = root; public $pwd = 123; public $dbname = test_123; //执行SQL语句返回相应的结果 //$sql 要执行的SQL语句 //$type 代表SQL语句的类型,0代表增删改,1代表查询 function query($sql,$type=1) { $db = new MySQLi($this->host,$this->uid,$this->pwd,$this->dbname); $result = $db->query($sql); if($type) { //如果是查询,显示数据 return $result->fetch_all(); } else { //如果是增删改,返回true或者false return $result; } } }
2.删除处理界面 sanchu.php
<?php $arr = $_POST[ck]; requireDBDA.class.php; $db = new DBDA(); //delete from nation where code in(n001,n002,n003) $str = implode(,,$arr); $sql = delete from nation where code in({$str}); /*echo $sql;*/ if($db->query($sql,0)) { header(location:piliangcaozuo.php); }
