Php 插入带有CodeIgniter活动记录的数据
我的问题是关于使用CodeIgniter活动记录插入数据。指南中有一个使用数组插入数据的示例：Php 插入带有CodeIgniter活动记录的数据,php,mysql,codeigniter,insert,Php,Mysql,Codeigniter,Insert,我的问题是关于使用CodeIgniter活动记录插入数据。指南中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，例如使用类似的语法： $this -> db -&
$data = array(
'title' => 'My title' ,
'name' => 'My Name' ,
'date' => 'My date'
);
$this->db->insert('mytable', $data);
$this -> db -> select (*);
$this -> db -> from ('users');
$this -> db -> where('id', $id);
$this -> db -> limit(1);
$query = $this->db->get();
set（）$this->db->set('name', $name);
$this->db->insert('mytable');
INSERT INTO mytable (name) VALUES ('{$name}')
