I suggest you to create models for each table using php artisan command.Models help you to write relationship and keep your code clean ,also it will quicker compare to db queries
For example php artisan make:model Branch
Branch Model
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Branch extends Model
{
use HasFactory;
protected $table="table_branch";
protected $guarded=['id'];
public function roadName(){
return $this->hasMany(RoadName::class);
}
}
RoadName model
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class RoadName extends Model
{
use HasFactory;
protected $table="roadname";
protected $guarded=['id'];
}
In your controller
$branch=\App\Models\Branch::query()->find($id);
$roadName=[];
if(isset($request->roads)&&count($request->roads)){
foreach ($request->roads as $value){
$roadName[]=new \App\Models\RoadName(['roadname' => $value]);
}
$branch->roadName()->saveMany($roadName);
}
