使用ajax在codeigniter中多次删除

Question

我实际上需要删除在 codeigniter 中通过 ajax 检查的多行。 当我单击删除按钮时，它给了我所有选中复选框的值，但它没有将所有值传递给控制器​​，因此只有最后一个选中的值被删除，请帮助我..

查看页面...当

<div class="multiple_del" title="Delete"><img src="../../images/minus.png"/></div>
                </div>

被点击

    <table border="0"  cellpadding="0" style="width:100%;margin:0px auto" cellspacing="0" id="product-table">

Javascript...

    $(document).ready(function(){

       $('.multiple_del').click(function(){
                var checkValues = $('input[name=checkboxlist]:checked').map(function()
                {
                    return $(this).val();
                }).get();
                //alert(checkValues);
                var url='<?php echo base_url(); ?>index.php/admin/delete_multiple';

                $.ajax({

                    type: 'POST',
                    url: url,
                    data: { ids: checkValues },
                    success:function(data)
                    {

                          window.location="<?php echo base_url(); ?>index.php/admin/users";
                          $( ".msg1" ).text( "Selected Users Deleted..!!");
                    }
                });

       });





});

控制器...ajax url 转到这个控制器

public function delete_multiple()//Delete Multiple Users
      {

        $ids=$this->input->post('ids');
        $this->admin_model->delete_multiple($ids);

      }

型号...

function delete_multiple($ids)//Delete Multiple Users
    {

     $this->db
          ->where_in('id', $ids)
          ->delete('tbl_users');

    }
