我的问题是关于用CodeIgniter活动记录插入数据。有一个在引导一个例子，与阵列插入数据：用CodeIgniter活动记录插入数据
$data = array(
'title' => 'My title' ,
'name' => 'My Name' ,
'date' => 'My date'
);
$this->db->insert('mytable', $data);
我不知道是否有插入活动记录的数据，例如在类似的语法一些其他的方式：
$this -> db -> select (*);
$this -> db -> from ('users');
$this -> db -> where('id', $id);
$this -> db -> limit(1);
$query = $this->db->get();
感谢。
您可以使用set()方法。
根据C11的文档，你可以使用下面的语法：
$this->db->set('name', $name);
$this->db->insert('mytable');
这将产生以下查询：
INSERT INTO mytable (name) VALUES ('{$name}')
希望这是你在找什么。

我会发现这是一个相当繁琐的答案。将来，我会建议更好的格式：每个文本解释使用不同的代码块。更清晰，在必要时更容易复制/粘贴代码。 – DonBoitnott
在笨
插入数据$query = $this->db->query('YOUR SQL QUERY');
或
$this->db->set('name', $name);
$this->db->insert('mytable'); // Produces: INSERT INTO mytable (`name`) VALUES ('{$name}')
的其他方式希望它可以帮助你。
一旦你插入记录...你从模型返回什么，以表明记录已成功插入？谢谢 –
@b_dubb您可以使用insert_id（）辅助方法。检查文档页面的详细信息：http://ellislab.com/codeigniter/user-guide/database/helpers.html –
