To use transactions in CakePHP, you can follow these steps:

  1. Start by including the TransactionAwareTrait in your model class. For example, if you want to use transactions in the User model, add the following line of code at the top of the file:
1
use CakeORMBehaviorTransactionAwareTrait;


  1. Next, include the TransactionAwareTrait in your class definition:
1
2
3
4
class User extends AppModel {
    use TransactionAwareTrait;
    // ...
}


  1. Now you can wrap your database operations within a transaction. For example, if you want to create a new user and save related data, you can do it within a transaction like this:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14

// Start the transaction
$this->User->getConnection()->begin();

try {
    // Perform your database operations here
    $user = $this->User->newEntity($data);
    if ($this->User->save($user)) {
        // Save related data (e.g., address)
        $address = $this->User->Address->newEntity($addressData);
        $address->user_id = $user->id;
        if ($this->User->Address->save($address)) {
            // Commit the transaction if all database operations succeed
            $this->User->getConnection()->commit();
            // Return a success message
            return 'User and related data saved successfully.';
        }
    }

    // Rollback the transaction if any of the database operations fail
    $this->User->getConnection()->rollback();
} catch (Exception $e) {
    // Rollback the transaction on exception (error occurred)
    $this->User->getConnection()->rollback();
    // Throw the exception or handle it as per your requirement
    throw $e;
}


  1. Remember to handle exceptions to ensure that the transaction is rolled back in case of any error or exception.


By using transactions, you can ensure that all database operations within the transaction are either committed or rolled back atomically, providing data consistency and integrity.
