如何在codeigniter中使用order-by？

Question

我知道这很简单，但我没有完成它。

$query = $this->db->get_where('prepared_forms', array('topic' => $this->input- >post('prepared_topics'))); 
$new_form = $query->row_array(); 

如何通过主题名称（ASC）订购预制表格？

Answer 1

$this->db->select("*") 
    ->from('prepared_forms') 
    ->where('topic', $this->input->post('prepared_topics')) 
    ->order_by('topic', 'asc') 
    ->get() 
    ->result_array(); 

Answer 2

$this->db->order_by("topic", "asc"); 
$query = $this->db->get_where('prepared_forms', array('topic' => $this->input->post('prepared_topics'))); 
$new_form = $query->row_array(); 

Answer 3

试试这个：

$query = $this->db->order_by('topic', 'asc')->get_where('prepared_forms', array('topic' => $this->input->post('prepared_topics'))); 
$new_form = $query->row_array();
