1.1.8. Events

There are several events that will automatically be called when interacting with Atlas mappers.

The insert(), update(), and delete() methods all have 3 events associated with them: a before*(), a modify*(), and an after*(). In addition, there is a modifySelect() event.

// Runs after the Select object is created, but before it is executed
modifySelect(Mapper $mapper, MapperSelect $select)

// Runs before the Insert object is created
beforeInsert(Mapper $mapper, Record $record)

// Runs after the Insert object is created, but before it is executed
modifyInsert(Mapper $mapper, Record $record, Insert $insert)

// Runs after the Insert object is executed
afterInsert(Mapper $mapper,
            Record $record,
            Insert $insert,
            PDOStatement $pdoStatement)

// Runs before the Update object is created
beforeUpdate(Mapper $mapper, Record $record)

// Runs after the Update object is created, but before it is executed
modifyUpdate(Mapper $mapper, Record $record, Update $update)

// Runs after the Update object is executed
afterUpdate(Mapper $mapper,
            Record $record,
            Update $update,
            PDOStatement $pdoStatement)

// Runs before the Delete object is created
beforeDelete(Mapper $mapper, Record $record)

// Runs after the Delete object is created, but before it is executed
modifyDelete(Mapper $mapper, Record $record, Delete $delete)

// Runs after the Delete object is executed
afterDelete(Mapper $mapper,
            Record $record,
            Delete $delete,
            PDOStatement $pdoStatement)

Here is a simple example with the assumption that the Record object has a validate() method and a getErrors() method. See the section on Adding Logic to Records and RecordSets.

namespace Blog\DataSource\Posts;

use Atlas\Mapper\Mapper;
use Atlas\Mapper\MapperEvents;
use Atlas\Mapper\Record;

/**
 * @inheritdoc
 */
class PostsEvents extends MapperEvents
{
    public function beforeUpdate(Mapper $mapper, Record $record)
    {
        if (! $record->validate())
            throw new \Exception('Update Error');
        }

    }
}

And you might have something like this in your code:

try {
    $atlas->update($post);
} catch (\Exception $e) {
    foreach ($post->getErrors() as $error) {
        echo $error . '<br/>';
    }
}
