php - 使用 Grocery CRUD CodeIgniter 获取自定义字段值

Question

如何从我的方法的另一个表中获取字段的值？当然我有它的表的主键。我想在这样的添加/编辑操作中做一些事情

if(is_empty(value_field_from_another_table)){
    $crud->edit_fields('first','second');
    $crud->add_fields('first','second');
}else{
    $crud->edit_fields('first');
    $crud->add_fields('first');
}

Answer 1

$query = $this->db->get_where('mytable', array('id' => $id), $limit, $offset);

or

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


foreach ($query->result() as $row)
{
    echo $row->title;
}
