Question

我在Laravel 5.0上花了更多的时间用于数据库事务，但是当我改为Laravel版本5.3。*它不能正常工作，即使我已经禁用了commit（）方法，所有数据仍然继续插入到数据库中。

if ($request->isMethod('post')) {

            DB::beginTransaction();
                $cats = new Cat();

                $cats->parent_id = $this->request->input('category_id');
                $cats->status = ($this->request->input('status'))?$this->request->input('status'):0;

                if($res['cat']  = $cats->save()) {

                    $catD = new CategoryDescriptions();
                    $catD->category_id = $cats->id;
                    $catD->language_id = 1;
                    $catD->name = $this->request->input('en_name');
                    if($res['cat2'] = $catD->save()){

                        $catD2 = new CategoryDescriptions();
                        $catD2->category_id = $cats->id;
                        $catD2->language_id = 2;
                        $catD2->name = $this->request->input('kh_name');
                        $res['all'] = $catD2->save();
                    }
                }
            if($res){

                //DB::commit();
                return $res;
            }
            return [false];
        }

选中此行（$res['cat']是boolean）：

if($res['cat']  = $cats->save()) {

这个（$res是array。你将数组比作布尔值！）：

 if($res){

正确的条件应为：

$res = array(); // the first line of your method

// .... your http method check, start transaction, etc.

if (!in_array(false, $res, true)) { // check if array doesn't contain 'false values'
    DB::commit();
}

Laravel 5.3数据库事务问题？
