I have document like that, how syntax for inserting new array inside jenis_barang_spesifik (my data inside jenis_barang_spesifik added by robomongo so I dont know how the syntax is).
Here is my syntax for inserting new array into jenis_barang_spesifik but it didn't work. Hope you guys can help me :D
Thanks
$ar_jenis_barang_spesifik = array(
'_id' => hash('sha1', time() . $jenis_barang_spesifik),
'jenis_barang_spesifik' => $jenis_barang_spesifik,
'created_on' => new MongoDate()
);
$result = $jenis_barang_spesifik_collection->update(array('product.jenis_barang_umum._id.' => $jenis_barang_umum), array('$push' => array('product.$.jenis_barang_umum.$.jenis_barang_spesifik' =>$ar_jenis_barang_spesifik)));
