How to fetch value from objects in laravel? - php

Question

I m making an app in which I want to get value of an object and also I want to get id while creating new user.
I was using drop down menu, and want to get id which was selected in previous dropdown.
#php
use Illuminate\Support\Facades\DB;
$uid=DB::table('users')->where('role_id','4')->get();
$counter=0;
$cid=DB::table('classses')->get();
$counterr=0;
$sec=DB::table('sections')->where('class_id',array('class_id' => $cid->id('class_id')))->get();
$counterrr=0;
#endphp
<select user="" name="parent_id">
<option value="null">User</option>
#foreach($uid as $user)
#if($counter==0)
<option selected="selected" value="{{$user->id}}">{{$user->name}}</option>
{{$counter++}}
#else
<option value="{{$user->id}}">{{$user->name}}</option>
#endif
#endforeach
</select>
<div class="col-md-6">
<select class="" name="class_id">
<option value="null">Class</option>
#foreach($cid as $cc)
#if($counterr==0)
<option selected="selected" value="{{$cc->id}}">{{$cc->title}}</option>
{$counterr++}}
#else
<option value="{{$cc->id}}">{{$cc->title}}</option>
#endif
#endforeach
</select>
<select section="" name="section_id">
<option value="null">Section</option>
#foreach($sec as $sc)
#if($counterrr==0)
<option selected="selected" value="{{$sc->id}}">{{$sc->title}}</option>
{{$counterrr++}}
#else
<option value="{{$sc->id}}">{{$sc->title}}</option>
#endif
#endforeach
</select>
As now I want that the object shows the value of selected id in class-dropdown menu and I want to put it in selected list of section
$sec=DB::table('sections')->where('class_id',$cid)->get();
I' m having issues in writing syntax over here.('class_id',$cid)
Also I want that a id on which this new user is going to be created , how to get that?
