How to insert array data in laravel 5.4 - laravel

Question

I have a product table and device table.
I have joined these two tables where I have selected device.id & product.name, now I want to insert this data into my existing device table using device.id.
I want to insert multiple dropdown values in my database. Can anyone tell me how can I solve this problem? Below is my Controller Code-
foreach ($request->all() as $value)
{
$deviceById= Device::find($request->id);
if($request->destination_type == 'dealer')
{
$deviceById->destination_location=$value->dealer_id;
}else
{
$deviceById->destination_location=$value->office_id;
}
$deviceById->save();
}
flash('Device Dispatch added successfully!')->success()->important();
return redirect()->back();

Answer 1

You can make array of all dropdowns value and convert into a json string and store it in database
You can do something like this. Change according to your requirement. It just a logic demo.
$deviceById= Device::find($request->id);
$destination = array();
foreach ($request->all() as $value)
{
if($request->destination_type == 'dealer')
{
$destination[] = $value->dealer_id;
}else
{
$destination[] = $value->office_id;
}
}
$jsonString = json_encode($destination);
$deviceById->destination_location = $jsonString
$deviceById->save();
flash('Device Dispatch added successfully!')->success()->important();
return redirect()->back();

I solve it this way.I had used Elequent ORM
if($request->destination_type == 'Dealer')
{
DB::table('devices')
->whereIn('id',$request->device_list)
->update(['dealer_id'=>$request->destination_location,'device_status'=>"Dispatch"]);
flash('Device Dispatch dealer added successfully!')->success()->important();
}else
{
DB::table('devices')
->whereIn('id',$request->device_list)
->update(['office_id'=>$request->destination_location,'device_status'=>"Dispatch"]);
flash('Device Dispatch office added successfully!')->success()->important();
}
