Relation Between 3 Tables

You can do relationships like this way.

firshtype.php

public function product(){
    return hasMany('App\Fishtype');
}

product.php

public function check(){
    return hasMany('App\Check');
}

Now, if you need to access any fishtype, you can try-

$fishtype = Fishtype::with('product', 'product.check')->where('id', 1)->first();

//printing product details that is associated with fishtype id 1
echo $fishtype->product->fishtype_id;

//printing check 
echo $fishtype->product->check->product_id;

Another older but good tutorial is https://scotch.io/tutorials/a-guide-to-using-eloquent-orm-in-laravel Gives good basic understanding.

@tisuchi

$fishtype = Fishtype::with('product', 'product.check')->where('id', 1)->first(); $fishtype = product.check ->product_id;

It should be like this-

echo $fishtype->product->check->product_id;

Instead of -

echo $fishtype = product.check ->product_id;
