Two models to store in database as one transaction - laravel

Question

I have two models Item and ItemDetail and they have a one-to-many relationship
One-to-many because I store the item details as Entity–attribute–value Table, it is nothing but a table the columns and label and value that stores ItemDetails as following
id|item_id_fkey|Label |Value
1 |1 |Color |Black
2 |1 |Description |Item 1 Details
3 |1 |Size |2x4x6
4 |2 |Description |Item 2 Details
5 |2 |Weight |1000
When I create an Item it ask me Item->name and Item->Price, on Submit it calls the ItemsController#store and redirect to ItemDetailController#create with newly created item id.
ItemDetailsController#create redirects to a Form with lot more fields to for gathering item details (e.g. ItemDetail->Description, ItemDetail->Dimensions etc), and on submit it stores the ItemDetails model.
Problem:(Not as complex as the situation), The issue is I want it to be such that if user creates item in first form and does not update the item details in second form, item shouldn't present in Item table as well.
In another words two store methods should be one single transaction.

Solution 1:
You can put everything in one form (may require creating dynamic HTML elements) and make your controller's store() method check if there's a non-empty array of values for the ItemDetail model. If there are values, create the Item model and the ItemDetail model(s), abort otherwise.
Solution 2:
You can have your ItemDetailsController#store method accept an $itemId which represents the newly created Item model and, as above, check if there's a non-empty array of values for the ItemDetail model(s) then create or abort.

Answer 2

I am assuming the two forms you are referring to are on separate pages and therefore are two separate requests to the server.
You could save the information in the first form in an object and pass it to the session.
Controller for First Form:
public function handleFirstForm() {
//perform validation and any other logic
$input = Input::get('contentsOfFirstForm');
Session::put('contentsOfFirstForm', $input);
}
The array you put into the session will only be used if the customer proceeds to fill out the item details.
Controller for Second Form:
public function handleSecondForm() {
$input = Input::get('contentsOfSecondForm');
//only save if the second form is not blank
if($input!==null) {
//run any other logic
//Save First Form
$item = Session::get('contentsOfFirstForm');
Item::create([$item]);
//Save Second Form
$itemDetails = $input;
ItemDetail::create([$item]);
}
}
You may also want to do a check using model events to see if the first form successfully saved, and ONLY then, save the second form, to prevent cases where your second model successfully saved, but the first model for whatever reason could not be saved.
