Yii2 include a controller in view - php

Question

I've got a very bad structured proj in Yii2, so if possible please don't pay attention to it.
Here is my proj structure:
In results.php I want to use my FlightsController class.
here is my include section from results.php:
include \yii\helpers\Url::to('#app/views/site/partials/header.php');
include \yii\helpers\Url::to('#app/controllers/HotelController.php');
include \yii\helpers\Url::to('#app/controllers/ActivitiesController.php');
include \yii\helpers\Url::to('#app/controllers/FlightController.php');
FlightController class:
class FlightController
{
require_once(\yii\helpers\Url::to('#app/sabre/rest_activities/LeadPriceCalculator.php'));
public static function start_rest_workflow($origin, $destination, $departureDate){
$workflow = new \Workflow(new \LeadPriceCalendarActivity($origin, $destination, $departureDate));
$result = $workflow->runWorkflow();
}
}
Here I get the error:
yii\base\ErrorException Expected array for frame 0
/controllers/FlightController.php yii\base\ErrorException::__toString
/views/site/results.php yii\web\View::unknown
In the first import require_once(\yii\helpers\Url::to('#app/sabre/rest_activities/LeadPriceCalculator.php')); .
How Can I correctly import a class from sabre directory from controllers directory?

Answer 1

i think that you don't know or not understand MCV software architecture pattern that it is working in yii2.
I m gona try to explain you a resum and a few sugerences :)
What is MVC :
Model: database and his logic.
View: html code and show/render the data.
Controller: big part of logic of code.
Then , whe you need a new page in you website , yo need think , is a other part of the same think or it isn't. If it is the same you must set the file in same path that other , like this example .
You have:
User/form.php
User/index.php
And you want to add a new page "view" where it see the data in a list , than the "view" is part of same think (User) you must set in the same page :
User/view.php
User/form.php
User/index.php
Then , in the controller you must write a big part of you logic that one think , in this case User , and in this Controller will be 3 actionsthan miniumm ( because you have 3 view )
UserController.php
public function actionView($id){
}
public function actionIndex(){
}
public function actionForm(){
}
And the last to explain is a models , it is simple , this are a object to represent a tables in you DB and you must be use like that , you can write a querys in this and call from controller and make somethiks.
In resume , if you will create "result.php" and you like write clean
code you set this file out of path "site" and create other "flight"
by exmaple , and now you can use the code from
FligthController.php en the function inside
public function actionResult(){}
