Search result with multiple tables relation in Laravel6 - laravel

Question

I'm trying to make search function with relation.
I could display all result using relation And an another code, simple one table search and get result works fine.
but I can't combine those two.
Could you teach me how to combine multiple tables into search function please?
public function order(Request $request)
{
$data = $request->all();
$products = Product::All();
$products = Product::with('categori')
->join('creators', 'creators.id', '=', 'products.creator_id')
->join('categoris', 'categoris.id', '=', 'products.categori_id')
->join('branches', 'branches.id', '=', 'products.br_id')
->join('users', 'users.id', '=', 'products.user_id')
->join('colors', 'colors.id', '=', 'products.color_id')
->get();
$products = Product::when($data['categori_id'], function ($query, $categori_id) {
return $query->where('categori_id', $categori_id);
})->
when($data['color_id'], function ($query, $color_id) {
return $query->where('color_id', $color_id);
})->get();
//return view('result_fb', compact('images'));
$data = array(
'title' => 'index',
'no' => 1,
'products' => $products,
);
return view('product.result', $data);
}

I am not sure if you need 'categori' relation to be loaded or not as there are few $products without it. For general, you can combine all your $products queries to one as follows:
$products = Product::join('creators', 'creators.id', '=', 'products.creator_id')
->join('categoris', 'categoris.id', '=', 'products.categori_id')
->join('branches', 'branches.id', '=', 'products.br_id')
->join('users', 'users.id', '=', 'products.user_id')
->join('colors', 'colors.id', '=', 'products.color_id')
->when($data['categori_id'], function ($query, $categori_id) use ($data) {
return $query->where('categori_id', $data['categori_id']);
})
->when($data['color_id'], function ($query) use ($data) {
return $query->where('color_id', $data['color_id']);
})->get();
If you want to use eager loading with eloquent rather then join, you can use like
$products = Product::with(['creator','categori','branch','user','color'])
->when($data['categori_id'], function ($query, $categori_id) use ($data) {
return $query->where('categori_id', $data['categori_id']);
})
->when($data['color_id'], function ($query) use ($data) {
return $query->where('color_id', $data['color_id']);
})->get();
But for that you Product model should have relations with same name as follows for categori relation:
class Product extends Model
{
public function categori()
{
return $this->belongsTo(Categori::class,'categori_id','id);
}
}
Same way you have to define for all relation used for product.

Try this:
$products = Product::with('categori')
->join('creators', 'creators.id', '=', 'products.creator_id')
->join('categoris', 'categoris.id', '=', 'products.categori_id')
->join('branches', 'branches.id', '=', 'products.br_id')
->join('users', 'users.id', '=', 'products.user_id')
->join('colors', 'colors.id', '=', 'products.color_id')
->when($data['categori_id'], function ($query, $categori_id) {
return $query->where('categori_id', $categori_id);
})
->when($data['color_id'], function ($query, $color_id) {
return $query->where('color_id', $color_id);
})
->get();
