The following tutorial column will introduce you to the detailed explanation of Laravel ORM operations. I hope it will be helpful to friends who need it!
Take out some data:
public function getOrderDetail($uid,$orderId){ $user = $this->check_user($uid); $columns = ['id', 'order_id', 'item_id', 'item_name', 'item_price', 'original_price', 'buy_num', 'real_num', 'cancel_num', 'status', 'create_time']; $ordeList = OrderItem::where('order_id',$orderId) -> orderBy('create_time','desc') ->get($columns)->toArray(); echo "<pre class="brush:php;toolbar:false">"; print_r($ordeList); echo ""; exit; }
Model::updateOrCreate(
['primary_key' => 8],
['field' => 'value', 'another_field' => 'another value']
);
Laravel subquery, multi-condition judgment: public function getCourseProgress($uid,$levelId=0,$lessonId=0,$type=0,$page=0) { //检测用户合法性 $user = $this->check_user($uid); //当前页数 $page = $page>0?$page:0; //每页显示数量 $perPage = config('bcc.per_page'); //显示字段 $columns = ['*']; #课程学习进度信息 $result = LessonProgress::where('customer_id',$uid) ->where(function($query) use ($type){ if($type) $query->where('source_type',$type); }) ->where(function($query) use ($levelId,$lessonId){ if($levelId && $lessonId) { $query->where(['level_id'=>$levelId,'lesson_id'=>$lessonId]); }elseif($levelId){ $query->where('level_id', $levelId); } })->get(); //->paginate($perPage,$columns,$pageName='',$page); if($result->isEmpty()) return $this->responseSuccess([],'No relevant information',20000); return $this->responseCollection($result,new CourseProgressTransformer); }

// 声母韵母分两类
$data=Pronounce::selectRaw('group_concat(`letter`) as letters')
->groupBy('pronounce_type')
->get()
->toArray();
sql clauses can be written directly in selectRaw

In Laravel full-stack development, effective methods for managing APIs and front-end logic include: 1) using RESTful controllers and resource routing management APIs; 2) processing front-end logic through Blade templates and Vue.js or React; 3) optimizing performance through API versioning and paging; 4) maintaining the separation of back-end and front-end logic to ensure maintainability and scalability.
