Save multidimensional array using Laravel and ajax - ajax

Question

I am building a pharmacy management system. I have a condition where I need to build a section
As shown in the picture, I need to store the data where the upper three should be same for all of the rows inputted below.
The form data is submitted as in the below picture.
But the data when looped and saved is not being saved as desired. Only the last row of the data is being inserted and I am also confused to store supplier, purchase date and note since these data should be repeated as many as the number of rows are added.
PurchaseController.php
public function storePurchase(PurchaseStoreRequest $request)
{
$purchase = new Purchase();
$count = count($request->name);
// return response()->json($request->all());
for ($i = 0; $i < $count; $i++) {
$purchase->supplier = $request->supplier;
$purchase->purchase_date = $request->purchase_date;
$purchase->description = $request->description;
$purchase->category = $request->category[$i];
$purchase->name = $request->name[$i];
$purchase->generic_name = $request->generic_name[$i];
$purchase->batch_number = $request->batch_number[$i];
$purchase->company = $request->company[$i];
$purchase->strength = $request->strength[$i];
$purchase->expiry_date = $request->expiry_date[$i];
$purchase->quantity = $request->quantity[$i];
$purchase->selling_price = $request->selling_price[$i];
$purchase->purchase_price = $request->purchase_price[$i];
$purchase->save();
}
return response()->json(['message' => 'Purchase Saved Successfully']);
}
Can someone help me to store these three fields in the database repeating the number of rows submitted ?
Currently only the last row is being inserted into the database.

This might be an another way to accomplish what you're looking for.
$sharedKeys = ['supplier', 'purchase_date', 'description'];
$sharedData = $request->only($sharedKeys);
$multiKeys = ['category', 'name', 'generic_name', 'batch_number', 'company', 'strength', 'expiry_date', 'quantity', 'selling_price', 'purchase_price'];
$multiData = $request->only($multiKeys);
for ($i = 0; $i < count($request->name); $i++) {
$individualData = array_combine($multiKeys, array_column($multiData, $i));
Purchase::create($sharedData + $individualData);
}

For every loop, you need to create a new instance, then It will create a new record on each loop :
public function storePurchase(PurchaseStoreRequest $request)
{
// $purchase = new Purchase();
$count = count($request->name);
// return response()->json($request->all());
for ($i = 0; $i < $count; $i++) {
$purchase = new Purchase(); // create new instance end with (); on each loop
$purchase->supplier = $request->supplier;
$purchase->purchase_date = $request->purchase_date;
$purchase->description = $request->description;
$purchase->category = $request->category[$i];
$purchase->name = $request->name[$i];
$purchase->generic_name = $request->generic_name[$i];
$purchase->batch_number = $request->batch_number[$i];
$purchase->company = $request->company[$i];
$purchase->strength = $request->strength[$i];
$purchase->expiry_date = $request->expiry_date[$i];
$purchase->quantity = $request->quantity[$i];
$purchase->selling_price = $request->selling_price[$i];
$purchase->purchase_price = $request->purchase_price[$i];
$purchase->save();
}
return response()->json(['message' => 'Purchase Saved Successfully']);
}
