我的问题是关于使用 CodeIgniter Active 记录插入数据。指南上有一个使用数组插入数据的示例：
$data = array(
'title' => 'My title' ,
'name' => 'My Name' ,
'date' => 'My date'
);
$this->db->insert('mytable', $data);
我想知道是否有其他方法可以插入活动记录数据，例如在类似的语法中：
$this -> db -> select (*);
$this -> db -> from ('users');
$this -> db -> where('id', $id);
$this -> db -> limit(1);
$query = $this->db->get();
谢谢。

您可以使用set() 方法。
根据 CI 文档，您可以使用以下语法：
$this->db->set('name', $name);
$this->db->insert('mytable');
这将产生以下查询：
INSERT INTO mytable (name) VALUES ('{$name}')
希望它是您正在寻找的。p>

**Save all and run**
【讨论】：
在 Codeigniter 中插入数据的其他方式
$query = $this->db->query('YOUR SQL QUERY');
或
$this->db->set('name', $name);
$this->db->insert('mytable'); // Produces: INSERT INTO mytable (`name`) VALUES ('{$name}')
希望对你有所帮助。
