<div class="col-md-5">
                <div class="right wh70percent">
                    <select class="form-control" name="status_sort" id="status_sort" placeholder="Status">
                      <option value="" selected="">Status</option>

...     

服务

public function dataCustomerList($param) 
    {
        $status = $param['status_sort'];
        $gender = $param['gender'];
        $published = $param['published'];

        if($published=='NO'){
            $published_check = 'NO';
            $published = 0;
        }
        else if($published=='YES'){
            $published_check = 'YES';
            $published = 1;
        }

        if(empty($status)) 
            $customer = customer::paginate(10);
        else
            $customer = customer::where('tb_customer.customer_status', '=', $status)
                                ->paginate(10);

        if(!empty($gender) AND !empty($published_check)){
            $customer = customer::where('tb_customer.gender', '=', $gender)
                                ->where('tb_customer.published', '=', $published)
                                ->paginate(10);
        }
        else if(!empty($gender)){
            $customer = customer::where('tb_customer.gender', '=', $gender)
                                ->paginate(10);
        }
        else if(!empty($published_check)){
            $customer = customer::where('tb_customer.published', '=', $published)
                                ->paginate(10);
        }
        return $customer;  
    }   

界面是这样的:/image/Wxy48.jpg

当我选择发布和性别，然后按搜索按钮时，数据将根据显示

当我只选择状态时，显示的数据按照

但是当我选择性别、发布和状态时，显示的数据不匹配

我想再问一下。除了我的代码之外，是否还有其他更简单的代码？

谢谢

您应该在每次添加过滤器时构建查询，例如:

    $customer = customer;

    if(!empty($status)) {
        $customer = $customer->where('tb_customer.customer_status', '=', $status);
    }

    if (!empty($gender)) {
        $customer = $customer->where('tb_customer.gender', '=', $gender);
    }

    if (!empty($published_check)) {
        $customer = $customer->where('tb_customer.published', '=', $published);
    }

    return $customer->paginate(10);

通过这种方式，您只需添加条件，无需检查每个案例并再次编写相同的查询

免责声明:我不是 Laravel 用户，您可能需要稍微编辑代码，只是说明构建查询的方式
