To fix this issue First of all $posts = new Post will not return you a data rather return an instance of Post class, instead find a post like this one.
code :
$posts = Post::find(1);
public function welcome()
{
     $posts = Post::find(1);
     $data['data'] = $posts->my_relationship;

     return view('welcome', $data);
}
{{$data->name}}
{{$data->company}}
public function welcome()
{
     $posts = Post::find(1);
     $data['data'] = $posts;

     return view('welcome', $data);
}

Any of those help When I click submit in signup page, I'm getting "Notice (8): Undefined variable: id [APP\views\merry_parents\report_card.ctp". , Use:
code :
$this->set('id', $this->data['MerryParent']['id']);

Does that help In your controller.
Replace Index Method/Function with below and try.
code :
public function index()
{
    $data['mid_cal'] = 0;
    $data['total_cost'] = 0;
    $this->load->view('calculator',$data);
    //print_r($total_cost);

}

passing variable from controller to view page shows undefined variable

fixed the issue. Will look into that further As you are not always passing temp variable to view, you must check that whether the variable exists or not before using it in your blade view. Check that whether the $temp variable exists before using it anywhere in blade
code :
@if(isset($temp))
@foreach($temp as $data)
 <tr> 
       <td> {{$data['NAME']}} </td>
       <td> {{$data['CONTACT']}} </td> 
       <td> {{$data['TEMP_ADDRESS']}} </td> 
</tr>
@endforeach
@endif
@php
$temp = isset($temp) ? $temp : [];
@endphp

wish helps you I'm very new to Yii2 Framework. I want to pass variable from controller to view. , Use render() instead of redirect().
code :
public function actionDeleteAll() {
    $var1 = 'abc';
    return $this->render('index', ['var_view' => $var1]);
}
