Laravel 4 - Return the id of the current insert - laravel

Question

I have the following query
public static function createConversation( $toUserId )
{
$now = date('Y-m-d H:i:s');
$currentId = Auth::user()->id;
$results = DB::table('pm_conversations')->insert(
array( 'user_one' => $currentId, 'user_two' => $toUserId, 'ip' => Request::getClientIp(), 'time' => $now )
);
return $results;
}
How would i return the id of the row just inserted?
Cheers,

Answer 1

Instead of doing a raw query, why not create a model...
Call it Conversation, or whatever...
And then you can just do....
$result = Conversation::create(array( 'user_one' => $currentId, 'user_two' => $toUserId, 'ip' => Request::getClientIp(), 'time' => $now ))->id;
Which will return an id...
Or if you're using Laravel 4, you can use the insertGetId method...In Laravel 3 its insert_get_id() I believe
$results = DB::table('pm_conversations')->insertGetId(
array( 'user_one' => $currentId, 'user_two' => $toUserId, 'ip' => Request::getClientIp(), 'time' => $now )
);
This method requires that the id of the table be auto-incrementing, so watch out for that...
The last method, is that you can just return the last inserted mysql object....
Like so...
$result = DB::connection('mysql')->pdo->lastInsertId();
So if you choose that last road...
It'll go...
public static function createConversation( $toUserId )
{
$now = date('Y-m-d H:i:s');
$currentId = Auth::user()->id;
$results = DB::table('pm_conversations')->insert(
array( 'user_one' => $currentId, 'user_two' => $toUserId, 'ip' => Request::getClientIp(), 'time' => $now )
);
$theid= DB::connection('mysql')->pdo->lastInsertId();
return $theid;
}
I would personally choose the first method of creating an actual model. That way you can actually have objects of the item in question.
Then instead of creating a model and just save()....you calll YourModel::create() and that will return the id of the latest model creation

Answer 2

You can use DB::getPdo()->lastInsertId().

Answer 3

Using Eloquent you can do:
$new = Conversation();
$new->currentId = $currentId;
$new->toUserId = $toUserId;
$new->ip = Request::getClientIp();
$new->time = $now;
$new->save();
$the_id = $new->id; //the id of created row

The way I made it work was I ran an insert statement, then I returned the inserted row ID (This is from a self-learning project to for invoicing):
WorkOrder::create(array(
'cust_id' => $c_id,
'date' => Input::get('date'),
'invoice' => Input::get('invoice'),
'qty' => Input::get('qty'),
'description' => Input::get('description'),
'unit_price' => Input::get('unit_price'),
'line_total' => Input::get('line_total'),
'notes' => Input::get('notes'),
'total' => Input::get('total')
));
$w_id = WorkOrder::where('cust_id', '=', $c_id)->pluck('w_order_id');
return $w_id;
