Question

我想创建一行代码来在我的 Web服务中使用 Yii2 创建分页，我希望结果如Api The Movie中有param < strong>页= 1 即可。在Google上进行观察后，我找到了一种方法，通过在我的控制器中添加限制和偏移来进行分页，但结果失败，偏移只添加一个id例如来自json 1 - 10的结果如果我在控制器中添加偏移它显示结果2 - 11

我的控制器

        public function actionGetdatapage($EmployeeId, $LeaveGroup, $Status, $Flag){
            $param['EmployeeId'] = $EmployeeId;
            $param['LeaveGroup'] = $LeaveGroup;
            $param['Status'] = $Status;
            $param['Flag'] = $Flag;

            return $this->getListrequestpage($param);
        }

        public function getListrequestpage($param){
            \Yii::$app->response->format = \yii\web\Response:: FORMAT_JSON;
            $data = HrAttLeaveReq::find()
            ->joinwith('employee')
            ->joinwith('dept')
            ->joinwith('branch')
            ->joinwith('leavetype')
            ->joinwith('position')
            ->where([
                'EmployeeId' => $param['EmployeeId'], 
                'LeaveGroup' => $param['LeaveGroup'], 
                'Status' => $param['Status'], 
                'HrAttLeaveReq.Flag' => $param['Flag']
                ])
            ->limit(10)
            ->offset(0)
            ->asArray()
            ->orderBy(['ReqNo' => SORT_ASC])
            ->all();

            $array = array();
            $i = -1;
            foreach($data as $d){

                $i++;
                $array[$i]['Method'] = 'Request';
                $array[$i]['ReqNo'] = $d['ReqNo'];
                $array[$i]['Branch'] = $d['branch']['Name'];

                $array[$i]['DeptId'] = $d['employee']['DeptId'];
                $array[$i]['Departement_Position'] = $d['dept']['Departement'] . ', ' . $d['position']['Position'];

                $array[$i]['Name'] = $d['employee']['Name'];
                $array[$i]['Photo'] = $d['employee']['Photo'];
                $array[$i]['Gender'] = $d['employee']['Gender'];

                if($d['StartDate'] == $d['EndDate']){
                    $array[$i]['Date'] = date('l, d M Y', strtotime($d['StartDate']));
                }else{
                    $array[$i]['Date'] = date('l, d M Y', strtotime($d['StartDate'])) . ' - ' . date('l, d M Y', strtotime($d['EndDate']));;
                }

                $array[$i]['LeaveGroup'] = $d['LeaveGroup'];
                $array[$i]['LeaveType'] = $d['LeaveType'];
                $array[$i]['Code_Status'] = $d['Status'];
                $array[$i]['Type'] = $d['leavetype']['Type'];
                $array[$i]['Description'] = '- ' . $d['Description'];

                if ($d['Status'] == 0) {
                    $array[$i]['Status'] = "PENDING";               
                }

                if ($d['Status'] == 1) {
                    $array[$i]['Status'] = "APPROVED";              
                }

                if ($d['Status'] == 2) {
                    $array[$i]['Status'] = "DENIED";                
                }

                $array[$i]['Flag'] = $d['Flag'];

            }

            $result = array();
            $result['value'] = empty($array) ? 0 : 1;
            $result['status'] = true;
            $result['result'] = $array;

            return $result;
    }

结果

{
    "value": 1,
    "status": true,
    "result": [
        {
            "Method": "Approval",
            "ReqNo": "RO170363",
            "Branch": "DCA CINERE",

            "LeaveGroup": "S",
            "LeaveType": "S",
            "Code_Status": "1",
            "Type": "SAKIT",
            "Description": "- This is Description ! ",
            "Status": "APPROVED",
            "Flag": "1"
        }
    ]
}

我需要Api The Movie

那么如何为 page = 1 添加参数？

Answer 1

尝试在模型方法中使用类似的东西：

$query = self::find();    
$countQuery = clone $query;
$pages      = new \yii\data\Pagination(['totalCount' => $countQuery->count()]);
$pages->defaultPageSize = $pageSize;
$model      = $query->offSet( $pages->offset )
                            ->limit( $pages->limit )
                            ->all();

return ['model' => $model, 'pages' => $pages];
