Lithium PHP框架-如何在m​​ysql上运行数据库事务？

Question

I have been working on an e-commerce website in PHP Lithium framework, actually this one is upgraded from CakePHP, we have to use transaction operation on db in mysql. Just don't know how to do db transaction in PHP Lithium framework.

Answer 1

Since Lithium uses PDO, you can just get the PDO object and call the beginTransaction() method.

$foo = app\models\Foo::create();
$pdo = Connections::get('default')->connection; 
$pdo->beginTransaction();
$foo->bar = 'Hello';
$foo->save();
$pdo->commit();

Answer 2

It doesn't seem like it is supported, unfortunately. See source of lithium/data/source/database/adapter/MySql.php .

An alternative may be to manually execute your queries.

Within your model, you can do:

static::connection->read($sql, $placeholders);

Where $sql is your raw SQL like:

$sql = 'SELECT * FROM users WHERE id = {:id}';

and $placeholders (optional) are your placeholders:

$placeholders = [
    'id' => 5
];

Using that knowledge, you should be able to set up a transaction.
