Saving data with relationship (OneToMany) Lavarel 5.1

Eduardo, good afternoon! Thanks for the answer.. Finally, the solution was as follows:

<input type='text' name='product_photos[0]['url']>
<input type='text' name='product_photos[0]['position']>

No controller:

$product = Product::create($request->all());
$product->photos()->createMany($request->get('product_photos'));

Regardless of how many product_photos you have, it works.

    <?php
/*
O modelo que cede a chave estrangeira que tem o hasmany o que possui a chave da entidade cedente possui belongsTo

Por exemplo:
A tabela pedidos possui a id do produto então no modelo de pedidos haverá.
*/
function produto()
{
    return $this->belongsTo('App\models\Produto');
}
/*
A tabela de produtos cede o id a tabela pedidos então no modelo de produto haverá:
*/
function pedido(){
    return $this->hasMany('App\models\Pedido','id_produto');
}

?>

I do not believe the createMany function exists in laravel 5.

I suggest you read the documentation in the official laravel documentation .

I indicate the steps below so that the registration is done the way you need it:

1 - Persist the product in the bank, this way you will have access to the product ID.

2 - you should loop in the received array from $ request-> get ('photos')

3 - each loop interaction:

3.1 - a ProductPhoto object must be created

3.2 - Assign the array values to the attributes of the created object and in the foreignkey field put the product ID created in step 1.

3.3 - perform a save on the ProductPhoto object
