And this is the payment migration table,
<?php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreatePaymentsTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('payments', function (Blueprint $table) {
$table->increments('id');
$table->integer('record_id')->unsigned();
$table->date('date');
$table->string('month');
$table->integer('year');
$table->integer('amount');
$table->integer('advance');
$table->integer('due');
$table->dateTime('created_at');
$table->dateTime('updated_at');
$table->foreign('record_id')->references('id')->on('records');
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::drop('payments');
}
}
The 'month' field in the form is a multiple selected field made with select2 which I want to store in the database but as far as I know each record in the database does not allow multiple values.How can I make it work? Please,help.

Answer 1

In the multiple select month, use name as array like name="month[]" so you will receive an array with month. Then, you can iterate this array and for each month insert a record in db. You can either create insert query foreach month or use batch insert.
public function store(Request $request)
{
$inputs = $request->all();
$months = $inputs['month'];
//Multiple insert queries
foreach ($months as $month) {
Payments::create([
'date' => $input['date'],
'year' => $inputs['year']
'month' => $month,
'amount' => $inputs['amount'],
'advance' => $inputs['advance'],
'due' => $inputs['due'],
'record_id' => $inputs['record_id']
]);
}
//-------------------------------------------------//
//Batch insert, use either one
$data = [];
foreach ($months as $month) {
$data[] = [
'date' => $input['date'],
'year' => $inputs['year']
'month' => $month,
'amount' => $inputs['amount'],
'advance' => $inputs['advance'],
'due' => $inputs['due'],
'record_id' => $inputs['record_id']
]
}
DB::table('payments')->insert($data);
}
Enjoy coding :)

Answer 2

On submit the form select2 always return the selected options in array. You can convert the array in string using the implode so you can store the result as 'january,may' in month field.
