How to decode in laravel join - php

Question

I have json resource collection like this
<?php
namespace App\Http\Resources;
use App\Models\Curriculum;
use Illuminate\Http\Resources\Json\JsonResource;
use Illuminate\Support\Facades\DB;
class CurriculumDisplayResource extends JsonResource
{
public function toArray($request)
{
return [
'id' => $this->id,
'title_section' => json_decode($this->title_section),
'learning_objective'=> json_decode($this->learning_objective),
'content_detail' =>
DB::table('curriculums')
->join('content_texts','curriculums.id','=','content_texts.curriculum_id')
->join('content_files','curriculums.id','=','content_files.curriculum_id')
->join('content_videos','curriculums.id','=','content_videos.curriculum_id')
->join('quizzes','curriculums.id','=','quizzes.curriculum_id')
->select('content_texts.title_text','content_texts.text_course',
'content_files.title_file','content_files.file_course','content_videos.title_video',
'content_videos.video_course','quizzes.title_quiz','quizzes.question','quizzes.answer','quizzes.right_answer')
->get(),
'parent_id' => $this->id,
];
}
}
Can I json decode the result of join quiz?, I just want to json decode the quizzes result. when I'm try display this json resource the result like this
this is the controller
<?php
namespace App\Http\Controllers\Course;
use App\Http\Controllers\Controller;
use App\Http\Resources\CurriculumResource;
use App\Models\Curriculum;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
class CurriculumController extends Controller
{
public function index()
{
return Curriculum::all();
}
public function store (Request $request)
{
$c = new Curriculum();
$c->title_section = json_encode($request->get('title_section'));
$c->learning_objective = json_encode($request->get('learning_objective'));
$c->user_id = Auth::id();
$c->course_id = $request->get('course_id');
$c->save();
return response(new CurriculumResource($c));
}
}
What's wrong with my code?, I've also made cast for title_quiz, question, answer and right_answer.

Answer 1

Hope this help your problem. It seems like you have double quotation mark
On your Model which has title_quiz, question, answer, and right_answer, add this line of code (depend on your Model):
Model.php
public function getTitleQuizAttribute($value){
return str_replace('\"','', $value);
}
public function getQuestionAttribute($value){
return str_replace('\"','', $value);
}
public function getRightAnswerAttribute($value){
return str_replace('\"','', $value);
}
public function title_quiz($value){
return str_replace('\"','', $value);
}
public function getAnswerAttribute($value){
return json_decode($value);
}
They will modify your string first then pass it to your response
