<select name="item_id" id="item_id" class="form-control select2">
#foreach($items as $item)
<option value="{{ $item->id }}">

TransactionController.php
This part is where I have problem, Two (2) tables need to be updated.
i.e.
Transactions table: (this part is already working, it's ok)
Name......| Item..........| Loaned.....| Due..
John Doe | Harry Potter | 09/22/20 | 09/23/20
Items table: (this part I don't know how to add it in the Controller)
Name...........| Onloan
Harry Potter | 1
• how update a foreign table (Items) in this controller so that
the "onloan" value of that $item->id is 1.
public function store(TransactionRequest $request)
{
Transaction::create([
'patron_id' => $request->patron_id,
'item_id' => $request->item_id,
'loaned' => $request->loaned,
'due' => $request->due,
]);
//This is what I tried, but it's not working.
Item::find($request->item_id);
$item->update([
'onloan' => 1,
]);
Please help. Thank you.

Υou can write it that way
Item::find($request->item_id)->update(['onloan' => 1,]);
Create you can also do it
Transaction::create([$request->all()]);
