批量假删除

1、前台获取被选中的数据的id（一个字符串）

代码：

//删除多个

$('#batch_del').click(function(){

// alert(123);

var list = $(':checkbox:checked');

ids = '';

list.each(function(){

ids += $(this).val() + ',';

});

// alert(ids);

ids = ids.substr(0,ids.length-1);

var url = "{:U('batch_del')}";

if(window.confirm('此操作不可逆，是否确认？')){

$.ajax({

url:url,

data:{ids:ids},

type:'GET',

dataType:'json',

success:function(res){

if(res.status == 200){

alert(res.msg);

location = location;

}else{

alert(res.msg);

}

}

});

}

});

2、后台获取所有id

①、用expolde()函数，把id值组成的字符串转为数组

②、循环这个数组，并执行更新数据操作

代码：

function batch_del(){

$ids = I('get.ids');

$str = explode(',',$ids);

// print_r($str);die;

$dept = M('Dept');

foreach($str as $v){

$map['dept_id'] = $v;

$res = $dept->where($map)->setField('status',0);

}

// die;

if($res){

$data['status'] = 200;

$data['msg'] = "删除成功";

$this->ajaxReturn($data);

}else{

$data['status'] = 400;

$data['msg'] = "删除失败";

$this->ajaxReturn($data);

}

// echo $dept->getLastSql();

}
