return back()->with('datosGuardados', 'Datos almacenados, Correctamente');
}
My Model:
class Project extends Model
{
protected $fillable = ['Sede','Alcance','Nombre','Cierre','Areas','P1','P2','P3','P4'];
protected $casts = [
'Areas' => 'array'
];
}
My migration:
public function up()
{
Schema::create('projects', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('Sede');
$table->string('Alcance');
$table->string('Nombre');
$table->date('Cierre');
$table->string('Areas');
$table->string('P1');
$table->string('P2');
$table->string('P3');
$table->string('P4');
$table->timestamps();
});
}

As you see the error is due to the checkbox that I don't know how to send it as a single array and store it in the database, I would appreciate any help. I was investigating and I did not find anything

Answer 1

$validator = $this->validate($request, [
'Sede'=> 'required|string|max:255',
'Alcance'=> 'required|string|max:255',
'Nombre'=> 'required|string|max:255',
'Cierre'=> 'required|date',
'Areas'=> 'required',
'P1'=> 'required|string|max:255',
'P2'=> 'required|string|max:255',
'P3'=> 'required|string|max:255',
'P4'=> 'required|string|max:255'
]);
// Add this line
$area = [];
foreach ($request->Areas as $key => $value) {
$area[$key] = $value;
}
// And then save in database with $area created using foreach.

Answer 2

Use this 'Areas.*'=> 'required', for validating the checkbox generally, moreover to insert the data under Areas, you can insert it via converting by json_encode($request->Areas);
