How to use DB transactions in laravel 5?

First, we need to understand why transactions are used in laravel projects. A database (db) transaction (referred to as: transaction) is a logical unit in the execution process of the database management system and consists of a limited sequence of database operations.

#db transaction is a very important concept and very useful as it manages project data securely. Laravel 5 provides transaction commit, rollback and other functions. So how to use DB transactions in your laravel project? Let us give you a simple example below.

I have three tables called "items", "items_city" and "items_count", and I need to add new data. At the same time, the "items" table is a main table, and then "items_city" and "items_count" are subtables of the "items" table.

So the reason why we need to use transactions is also very simple, because when I add a new record in the db (database), if there is an error when inserting the "items_city" table, then "items" and "items_count" Table records will be automatically rolled back and it will return true if all table data is inserted successfully.

The code examples are as follows:

DB::transaction(function () {
    $item_id = DB::table('items')->insertGetId(['title' => 'Hery']);

    DB::table('items_city')->insert(['item_id'=>$item_id,'name' => 'India']);
    DB::table('items_count')->insert(['item_id'=>$item_id,'price' => 10]);
});
