Laravel add values to object based on foreign key - arrays

Question

I have a TABLE A called diagnoses . It has a disease_id and a visit_id. I am trying to return the diagnosis from TABLE A along with the disease name and visit details. I keep getting sql syntax errors. Is there a recommended way to push an objects to the array?
My code is
public function diagnosis_diseases(Disease $disease) {
$id = $disease->id;
$items = DB::select(DB::raw('SELECT * FROM diseases WHERE diseases.id = '.$id.' ;'));
foreach($items as $item){
$diagnosis = DB::select(DB::raw(' select * from diagnoses
where disease_id = '. $id.';' ));
$items->push($diagnosis);
}
dd($items);
}

Answer 1

You might need to use an inner join:
public function diagnosis_diseases(Disease $disease) {
$id = $disease->id;
$items = DB::select(DB::raw('SELECT * FROM diseases WHERE diseases.id = '.$id.' ;'));
foreach($items as $item){
$diagnosis = DB::select(DB::raw(' select * from diagnoses
inner join diseases on diagnoses.id = ' .$id' '));
$items->push($diagnosis);
}
dd($items);
}
