Laravel update multiple database rows with Eloquent - php

Question

I want to update the products leased count when a product is rented to a customer.
The owner of the website can rent multiple things. I do this by cloning with Ajax.
Now, when someone has rented like 2 chairs and 1 table, i want to update the products_leased row for both products. How would i do that?
The error i get:
`SQLSTATE[01000]: Warning: 1265 Data truncated for column 'product_leased' at row 1 (SQL: update `products` set `product_leased` = 3 5, `updated_at` = 2017-06-07 19:57:03 where `id` = 1)`
My controller:
public function create_order($id) {
$customer = Customer::find($id);
$pr = Product::get();
$rent_from = Request::input('rent_from');
$rent_till = Request::input('rent_till');
$productArray = Request::get('product_name');
$productCountArray = Request::get('product_count');
$rentProduct = new cRent;
$rentProduct->customer_id = $customer->id;
$rentProduct->rent_from = $rent_from;
$rentProduct->rent_till = $rent_till;
$rentProduct->rented_products = implode(', ', $productArray);
$rentProduct->rented_products_count = implode(', ', $productCountArray);
$rentProduct->save();
$pru = Product::find($id);
$pru->product_leased = implode(' ', $productCountArray);
$pru->update();
return back();
}
The code above works only when one product has been rented. Not when i rent 2 products.
Thanks in advance.

Answer 1

Why are you passing in the same $id to
$customer = Customer::find($id);
and
$pru = Product::find($id);
?
Instead of imploding the product names and counts and storing them together, why not create separate rent records for each product and relate them as a one-to-many? Assuming product name and product count line in the arrays, something to the effect of:
foreach(array_combine($productArray, $productCountArray) as $product_name => $count){
$product = Product::where('name', $product_name)->first();
$rentProduct = new cRent;
$rentProduct->customer_id = $customer->id;
$rentProduct->rent_from = $rent_from;
$rentProduct->rent_till = $rent_till;
$rentProduct->product_id = $product->id
$rentProduct->count = $count;
$rentProduct->save();
}
Better yet, don't pass in the product names, instead pass the product ids in from the form.

Answer 2

$rentProduct = new cRent;
the code above indicates only one instance of your cRent off-course if you want have another transaction with the database with a different values or data another instance is needed
I think what you want is something like this
public function create_order($id) {
$customer = Customer::find($id);
$pr = Product::get();
$rent_from = Request::input('rent_from');
$rent_till = Request::input('rent_till');
$productArray = Request::get('product_name');
$productCountArray = Request::get('product_count');
foreache($productArray as $prod){
$rentProduct = new cRent;
$rentProduct->customer_id = $customer->id;
$rentProduct->rent_from = $rent_from;
$rentProduct->rent_till = $rent_till;
$rentProduct->rented_products = $prod
$rentProduct->rented_products_count = //not sure in this line
$rentProduct->save();
}
$pru = Product::find($id);
$pru->product_leased = implode(' ', $productCountArray);
$pru->update();
return back();
}
