Basic Insert / Update / Delete Operations

Insert Options

Insert one document

If you are inserting only one document:

$xmongodb->insert('collection', 
    array('field1' => 'value1',
          'field2' => 'value2',
          'field3' => 'value3'
        )
);

Insert multiple documents

If you are inserting a group of documents:

$xmongodb->insert_batch('collection', array(
    0 => array('field1' => 'value11','field2' => 'value21','field3' => 'value31'), 
    1 => array('field1' => 'value12','field2' => 'value22','field3' => 'value32')
    )
);

Update Options

Update a single document

Before an update, you must to specify a where condition:

$xmongodb->where(array('field1'=>'value1'))->update('collection', 
        array('field2' => 'value2',
              'field3' => 'value3'
        ),
        $options
);

This method only will update first collection found in the where condition. Specify an unique key to be sure you update the correct document.

- $options:

* array('upsert' => true)     Create a new document if nothing found

Update multiple documents

$xmongodb->where(array('field1'=>'value1'))->update_batch('collection', 
        array('field2' => 'value2',
              'field3' => 'value3'
        )
);

Update using SET

$xmongodb->set(array('field2' => 'value2', 'field3' => 'value3'))
         ->where(array('field1'=>'value1'))
         ->update('collection');

Reconnect to another mongoDB instance

After you have created the config class, you can reuse to another connection:

// $congig is an object of a previous XMonfoDBConfig instance
$config->setDB('myotherdb','myuser','mypass');
$xmongodb_other = new XMongoDB($config);
