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 require"DBDA.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
<?phpclass 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 = $_POST["ck"];require"DBDA.class.php";$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");}
