How to store different single array to database? - php

Question

I have two arrays which I can get after form submit:
$product_id = $request->get('product_id');
// [1, 3, 4]
$quantity = $request->get('quantity');
// [5, 1, 2]
Now I want to submit this arrays into database where I want to pick the purchase_price from product database. I'm not sure how to assign product_id to product_quantity (index 0 to 0, 1 to 1, 2 to 2) and store into database.
Sample data to store into carts:
[1 5 120 ],
[3 1 230 ],
[4 2 340 ],
foreach ($product_id as $product)
{
}
DB::table('carts')->insert(
['product_id' => '',
'quantity' => 0,
'purchase_price' =>
]
);
Just for clarification:
product_id and quantity come from dynamic input box means number of product_id and quantity are same but it could be n times as user wanted. So I store it as arrays.
Now from this array I wanted to store it in database where I want to store with product_id with quantity.

Answer 1

Lets give you some suggetions:
If you have below array - if not then make it array like below:
$dataset = [
0 => [
'product_id' => 1,
'quantity' => 5,
'purchase_price' => 120,
],
1 => [
'product_id' => 3,
'quantity' => 1,
'purchase_price' => 230,
],
2 => [
'product_id' => 4,
'quantity' => 2,
'purchase_price' => 340,
]
];
Now you have to write INSERT query for this:
$result = Cart::insert($dataSet);
if ($result)
return true;
else
return false;
You will get an idea how to do it after seeing above code...good luck

Please check out this sample.
you can parse 2d array and convert it to json to store in the database then decode back:
$product_id = [1,2,3];
// [1, 3, 4]
$quantity = [5,1,2];
// [5, 1, 2]
$output=[120,230,340];
$out=[];
for ($i=0; $i < count($product_id); $i++) {
$out[$i]=[$product_id[$i],$quantity[$i],$output[$i]];
}
dd(json_encode($out));
output:
"[[1,5,120],[2,1,230],[3,2,340]]"

Answer 3

You can use
foreach ($product_id as $key=>$product)
{
//select purchase price from table by using the $product value
$purchase_price = *your select code here*
DB::table('carts')->insert([
'product_id' => $product,
'quantity' => $quantity[$key],
'purchase_price' => $purchase_price
]);
}
Let me know if not works
