php批量删除

php批量删除可以实现多条或者全部数据一起删除

php批量删除

新建php文件显示数据库中内容：

<table width="100%" border="1" cellpadding="0" cellspacing="0">

	<tr>

    	<td><input type="checkbox" id="qx" onclick="xuanzhong()" />全选</td>

    	<td>代号</td>

        <td>名称</td>

    </tr>

    <?php

	include("DBDA.class.php");

	$db = new DBDA();

	$sql = "select areacode，areaname from nation";

	$attr = $db->Query($sql);

	foreach($attr as $v)

	{

		echo "<tr>

		<td><input type='checkbox' name='ck[]' class='ck' value='{$v[0]}' /></td>

    	<td>{$v[0]}</td>

        <td>{$v[1]}</td>

    </tr>";

	}

	?>

</table>

DBDA.class.php文件为数据库查询的类文件：

<?php

class DBDA

{

	public $host="localhost";

	public $uid = "root";

	public $pwd = "";

	public $dbname = "12345";

	//成员方法

	public function Query($sql,$type=1)

	{

		$db = new MySQLi($this->host,$this->uid,$this->pwd,$this->dbname);

		$r = $db->query($sql);

		if($type==1)

		{

			return $r->fetch_all();

		}

		else

		{

			return $r;

		}

	}

}

php批量删除

在表格中加入选择复选框：

<td><input type="checkbox" id="qx" onclick="xuanzhong()" />全选</td>

<td><input type='checkbox' name='ck[]' class='ck' value='{$v[0]}' /></td>

显示：

用js控制复选框的全选和取消全选：

<script type="text/javascript">

	function xuanzhong()

	{

		//取全选按钮的选中状态

		var zt = document.getElementById("qx").checked;

		//让下面所有的checkbox选中状态改变

		var ck = document.getElementsByClassName("ck");

		for(var i=0;i<ck.length;i++)

		{

			if(zt)

			{

				ck[i].setAttribute("checked","checked");

			}

			else

			{

				ck[i].removeAttribute("checked");

			}

		}

	}

</script>

表格外侧追加form表单和提交按钮，并且用js控制点击删除时显示详细的提示信息完整php代码：

<!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>

</head>

<body>

<form action="shanchu.php" method="post">

<table width="100%" border="1" cellpadding="0" cellspacing="0">

	<tr>

    	<td><input type="checkbox" id="qx" onclick="xuanzhong()" />全选</td>

    	<td>代号</td>

        <td>名称</td>

    </tr>

    <?php

	include("DBDA.class.php");

	$db = new DBDA();

	$sql = "select areacode,areaname from chinastates";

	$attr = $db->Query($sql);

	foreach($attr as $v)

	{

		echo "<tr>

		<td><input type='checkbox' name='ck[]' class='ck' value='{$v[0]}' /></td>

    	<td>{$v[0]}</td>

        <td>{$v[1]}</td>

    </tr>";

	}

	?>

</table>

<input type="submit" value="删除" onclick="return tishi()" />

</form>

</body>

<script type="text/javascript">

	function xuanzhong()

	{

		//取全选按钮的选中状态

		var zt = document.getElementById("qx").checked;

		//让下面所有的checkbox选中状态改变

		var ck = document.getElementsByClassName("ck");

		for(var i=0;i<ck.length;i++)

		{

			if(zt)

			{

				ck[i].setAttribute("checked","checked");

			}

			else

			{

				ck[i].removeAttribute("checked");

			}

		}

	}

	function tishi()

	{

		//找所有选中项

		var ck = document.getElementsByClassName("ck");

		var str = "";

		for(var i=0;i<ck.length;i++)

		{

			if(ck[i].checked)

			{

				str += ck[i].value+",";

			}

		}

		return confirm("确定要删除以下数据么："+str+"");

	}

</script>

</html>

php批量删除

最后新建删除处理的php文件;

<?php

$ck = $_POST["ck"];

include("DBDA.class.php");

$db = new DBDA();

//第一种方式

/*foreach($ck as $v)

{

	$sql = "delete from nation where code='{$v}'";

	$db->Query($sql,0);

}*/

//第二种方式

//in ('','','','','')

$str = implode("','",$ck);

$str = "('{$str}')"; 

$sql = "delete from nation where code in {$str}";

$db->Query($sql,0);

header("location:main.php");
