How to insert into pivot table after form submission using attach? - laravel

Question

I'm using Laravel eloquent and I'm trying to insert the selected user id from my form and the generated ticket id into my pivot table using attach but I don't know how to do this.
store function
public function store(Request $request
{
$ticket = new Ticket;
$ticket->organisation_name = $request['organisation_name'];
$ticket->postal_address = $request['postal_address'];
$ticket->physical_address = $request['physical_address'];
$ticket->description_brief = $request['description'];
$ticket->hours_dedicated = $request['hours'];
$ticket->commencement_date = $request['start_date'];
$ticket->due_date = $request['due_date'];
$ticket->client_id = $request['client_id'];
$ticket->save();
//trying to use attach here
return redirect('/home');
}
form

}
Ticket.php
class Ticket extends Model

public function client(){
return $this->belongsTo(Client::class,'client_id');

public function users(){

protected $primaryKey = 'ticket_id';
public $timestamps = false;

Answer 1

As per the documentation you can simply pass the id you want to attach. After $ticket->save(); you can add the following:
$ticket->users()->attach($request->input('id'));
attach() will also work if you pass an array of ids, a model, a collection of ids or a collection of models.
