"Undefined variable" in laravel 5.2 view - php

Question

I'm getting a undefined variable error in my view if I include this route with a parameter:
<div class="table-toolbar">
<div class="row">
<div class="col-md-6">
<div class="btn-group">
<i class="fa fa-plus"></i> Add new
</div>
</div>
</div>
</div>
Here's my full controller for that given view:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Model\CampusMajor;
use App\Model\CampusMajorsFacilities;
class CampusMajorsFacilitiesController extends Controller
{
//
public function index($campusMajorId)
{
$campusMajorsFacilities = CampusMajorsFacilities::ofCampusMajor($campusMajorId)->get();
$data = [
'campusMajorsFacilities' => $campusMajorsFacilities,
'campusMajor' => $campusMajorId
];
return view('major-facilities.index', $data);
}
public function add($campusMajorId)
{
$campusMajorsFacilities = new CampusMajorsFacilities;
$data = [
'campusMajorsFacilities' => $campusMajorsFacilities,
'campusMajorId' => $campusMajorId,
'formIs' => 'add'
];
return view('major-facilities.form', $data);
}
public function save(Request $request,$campusMajorId)
{
$this->validation($request);
$post = $request->all();
$campusMajorsFacilities = $this->bindToObject($post,$campusMajorId);
$campusMajorsFacilities->save();
return redirect()->route('major-facilities.index', $campusMajorId)->with('message','Item added Succesfully');
}
public function edit($campusMajorId, $id)
{
$campusMajorsFacilities = CampusMajorsFacilities::find($id);
$data = [
'campusMajorsFacilities' => $campusMajorsFacilities,
'campusMajorId' => $campusMajorId,
'formIs' => 'edit'
];
return view('major-facilities.form', $data);
}
public function update(Request $request,$campusMajorId,$id)
{
$this->validation($request);
$post = $request->all();
$campusMajorsFacilities = $this->bindToObject($post,$campusMajorId,$id);
$campusMajorsFacilities->save();
return redirect()->route('major-facilities.index', $campusMajorId)->with('message','Item updated Succesfully');
}
private function validation($request)
{
$this->validate($request,[
'title' => 'required',
'description' => 'required',
'content' => 'required',
'campus_major_id' => 'required'
]);
}
public function delete($campusMajorId,$id)
{
$campusMajorsFacilities = CampusMajorsFacilities::find($id);
$campusMajorsFacilities->delete();
return redirect()->route('major-facilities.index', $campusMajorId)->with('message','Item deleted Succesfully');
}
private function bindToObject($post,$campusMajorId,$id=null)
{
if(is_null($id)){
$campusMajorsFacilities = new CampusMajorsFacilities;
} else {
$campusMajorsFacilities = CampusMajorsFacilities::find($id);
}
$campusMajorsFacilities->major_campus_id = $campusMajorId;
$campusMajorsFacilities->title = $post['title'];
$campusMajorsFacilities->description = $post['description'];
$campusMajorsFacilities->content = $post['content'];
return $campusMajorsFacilities;
}
}
And my model
<?php
namespace App\Model;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class CampusMajorsFacilities extends Model
{
//
use SoftDeletes;
public function CampusMajor()
{
return $this->belongsTo('App\Model\CampusMajor');
}
public function scopeOfCampus($query, $campus_id)
{
return $query->where('campus_id', $campus_id);
}
public function scopeOfCampusMajor($query, $campus_major_id)
{
return $query->where('campus_major_id', $campus_major_id);
}
}
If I comment out the route I passed the view just fine, I don't know where I went wrong.

Answer 1

You have passed $campusMajorId from controller to view as campusMajor only, not as campusMajorId.
Hence the variable is undefined in the view.
