How to save primary key to another table as FK in laravel 5.5

Question

I am confused in this problem i have two model one is (business_master) and other one is ( page_master)

I want to save primary key (id) from business_master table to (page_master) as Fk (business_id).

Right now i hardcoded business_id in my controller.

My Controller:

        $page = new Page();
        $page->page_name = Input::get('page_name');
        $page->page_url = Input::get('page_url');
        $page->business_id = 1;

        $page->save();

and its model:

          class Page extends Model
        {
        protected $table = 'page_master';

     protected $fillable = ['business_id','page_url','page_name'];
    }

And my businees_master Model:

   class Business extends Model
  {
   protected $table = 'business_master';

protected $fillable = ['user_id','business_name','business_url'];


 }

how i can save business_id into my page_master table using relationships? Any help would be highly appreciated!

                   public function addPage(Request $id)
{
    $fieldsValidation = [

        'page_name' => 'required|unique:page_master,page_name',
        'page_url' => 'required|unique:page_master,page_url',
    ];
    $validator = Validator::make(Input::all(), $fieldsValidation);

    if ($validator->fails()) {
        $resultArray = [
            'status' => 0,
            'message' => $validator->errors()->first(),
            'dataArray' => []

        ];
    } else {
        $business = Business::find(2);
        $page = new Page();
        $page->page_name = Input::get('page_name');
        $page->page_url = Input::get('page_url');
        $page->business()->associate($business);

        $page->save();
        $resultArray = ['status' => 1, 'message' => 'Page url added!', 'dataArray' => $page];

    }
    return Response::json($resultArray, 200);


}

Answer 1

So you have two models

1) Business

2)Page

You have to define one to many relationship , So define relation pages in Business model

public function pages()
{
    return $this->hasMany('App\Page');
}

And You have to define the Inverse relationship also in the Page model,

public function business()
{
    return $this->belongsTo('App\Business');
}

After defining relationships, you can query the relationships .

Like you are trying this query, So with the relationship you can do,

    $business = \Business::find(1); //here 1 as you gave but you can pass id as per your requirement
    $page = new Page();
    $page->page_name = Input::get('page_name');
    $page->page_url = Input::get('page_url');
    $page->business()->associate($business); 
    $page->save();

This will help you for sure. But you have to read the blog and understand the Laravel relationship
