Laravel Eloquent ORM Transactions

You can do this:

DB::transaction(function() {
      //
});

Everything inside the Closure executes within a transaction. If an exception occurs it will rollback automatically.

If you don't like anonymous functions:

try {
    DB::connection()->pdo->beginTransaction();
    // database queries here
    DB::connection()->pdo->commit();
} catch (\PDOException $e) {
    // Woopsy
    DB::connection()->pdo->rollBack();
}

Update: For laravel 4, the pdo object isn't public anymore so:

try {
    DB::beginTransaction();
    // database queries here
    DB::commit();
} catch (\PDOException $e) {
    // Woopsy
    DB::rollBack();
}

If you want to use Eloquent, you also can use this

This is just sample code from my project

        /* 
         * Saving Question
         */
        $question = new Question;
        $questionCategory = new QuestionCategory;

        /*
         * Insert new record for question
         */
        $question->title = $title;
        $question->user_id = Auth::user()->user_id;
        $question->description = $description;
        $question->time_post = date('Y-m-d H:i:s');

        if(Input::has('expiredtime'))
            $question->expired_time = Input::get('expiredtime');

        $questionCategory->category_id = $category;
        $questionCategory->time_added = date('Y-m-d H:i:s');

        DB::transaction(function() use ($question, $questionCategory) {

            $question->save();

            /*
             * insert new record for question category
             */
            $questionCategory->question_id = $question->id;
            $questionCategory->save();
        });

If you want to avoid closures, and happy to use facades, the following keeps things nice and clean:

try {
    \DB::beginTransaction();

    $user = \Auth::user();
    $user->fill($request->all());
    $user->push();

    \DB::commit();

} catch (Throwable $e) {
    \DB::rollback();
}

If any statements fail, commit will never hit, and the transaction won't process.
