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


<?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"];

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");
}
