使用手动where语句的具有多个更新条件的Codeigniter模型 [英] Codeigniter model with multiple update conditions using manual where statement

问题描述

我在返回数据的模型中有这段代码

I have this code in model that returns data

$this->db->select('title, content, date');

$where = "name='Joe' AND status='boss'";

$this->db->where($where);

$query = $this->db->get('mytable');

return $query->result();

我正在使用手册where，我想知道是否允许在更新甚至删除中使用手册的概念.

I am using a manual where and i wanted to know whether the concept of manual where in updates and possibly in deletes is allowed.

此代码根据单个where条件更新表

This code updates a table based on a single where condition

$data = array(
               'title' => $title,
               'name' => $name,
               'date' => $date
             );

$this->db->where('id', $id);
$this->db->update('mytable', $data);

这样做是在代码点火器中允许的吗?

Is doing this allowed in codeigniter

$data = array(
               'title' => $title,
               'name' => $name,
               'date' => $date
             );

$where = "id=$id, name='Joe' AND status='boss'";

$this->db->where($where);

$this->db->update('mytable', $data);

推荐答案

根据CodeIgniter中的文档在中，您必须在此处用OR或AND "id=$id, name='Joe'提及.

As per document in CodeIgniter Where, you have to mention here with OR or AND "id=$id, name='Joe'.

$where = "id=$id AND/OR name='Joe' AND status='boss'";

或使用数组
