Transaction in laravel eloquent query with multiple insert queries - laravel

Question

I want to know how to use transaction query to rollback if my queries have errors and commit if not. I have queries that use foreach cause of having multiple data. here's what I'm trying.
DB::transaction(function(){
$receiving = New Table1;
$receiving->created_on = \Carbon\Carbon::now();
$receiving->created_by = Auth::user()->id;
$receiving->received_on = \Carbon\Carbon::parse($request->DateAcquired);
$receiving->received_by = Auth::user()->id;
$receiving->checked_on = \Carbon\Carbon::now();
$receiving->checked_by = Auth::user()->id;
$receiving->remark = $request->Remarks;
$receiving->save();
foreach ($request->data as $data)
{
$asset = New Table2;
$asset->category = $data[0];
/*$asset->asset_number = $data[1];*/
$asset->name = $data[2];
$asset->brand = $data[3];
$asset->model = $data[4];
$asset->ownership_type = $data[5];
$asset->serial_number = $data[6];
$asset->mac_address = $data[7];
$asset->cpu = $data[8];
$asset->memory = $data[9];
$asset->hard_disk = $data[10];
$asset->os = $data[11];
$asset->remark = $data[12];
$asset->description = $data[13];
$asset->date_acquired = \Carbon\Carbon::parse($request->DateAcquired);
$asset->receiving_id = $receiving->id;
$asset->save();
}
});
I also tried using DB::beginTransaction();
but I'm getting an error of
undefined beginTransaction() function in query builder.

Answer 1

As mentioned in Laravel Database Transactions:
You may use the transaction method on the DB facade to run a set of
operations within a database transaction. If an exception is thrown
within the transaction Closure, the transaction will automatically be
rolled back. If the Closure executes successfully, the transaction
will automatically be committed. You don't need to worry about
manually rolling back or committing while using the transaction
method:
but as I can see in your code that you are using $request variable within the callback function of transaction, so at this point, you should pass the $request to the callback function to use it.
your code will like below:
DB::transaction(function() use ($request) {
// put your code here
});

Answer 2

You may need to pass your variable to the transaction via use()
DB::transaction(function() use ($request) {
$receiving = New Table1;
$receiving->created_on = \Carbon\Carbon::now();
$receiving->created_by = Auth::user()->id;
$receiving->received_on = \Carbon\Carbon::parse($request->DateAcquired);
$receiving->received_by = Auth::user()->id;
$receiving->checked_on = \Carbon\Carbon::now();
$receiving->checked_by = Auth::user()->id;
$receiving->remark = $request->Remarks;
$receiving->save();
foreach ($request->data as $data)
{
$asset = New Table2;
$asset->category = $data[0];
/*$asset->asset_number = $data[1];*/
$asset->name = $data[2];
$asset->brand = $data[3];
$asset->model = $data[4];
$asset->ownership_type = $data[5];
$asset->serial_number = $data[6];
$asset->mac_address = $data[7];
$asset->cpu = $data[8];
$asset->memory = $data[9];
$asset->hard_disk = $data[10];
$asset->os = $data[11];
$asset->remark = $data[12];
$asset->description = $data[13];
$asset->date_acquired = \Carbon\Carbon::parse($request->DateAcquired);
$asset->receiving_id = $receiving->id;
$asset->save();
}
});
