CodeIgniter Active Record 多个 WHERE 子句

Question

我正在尝试转换此查询：

 SELECT * FROM table WHERE condition1 = 'example' AND (date1 = 'date' OR renewal1 = 'renewal');

进入 CodeIgniter 的 Active Record 格式。我尝试了以下方法：

$q = $this->db->select('*');
$q = $this->db->from('table');
$q = $this->db->where('condition1 = condition');
$q = $this->db->where('date1 = date OR renewal = renewal');
$q = $this->db->get();
$results = $q->result();

但这并没有达到预期的效果。它似乎没有在第二组条件周围放置括号，这导致查询无法按预期工作。我还能怎么做才能代表我想要的？

感谢您的帮助！

你可以使用

$this->db->select('*');
$this->db->from('table');
$this->db->where('condition1 =',' condition');
$where = '(date1 = "date" OR renewal1 = "renewal")';// you can use your condition like this
$this->db->where($where);
$q = $this->db->get();
$results = $q->result();
