[英]codeigniter select query with multiple where clause
使用get_where
查詢時出現錯誤。 我讀到它已被刪除。 任何人都可以建議我應該進行哪些更改,以便可以使用多個用戶定義的where
子句獲取值。
<?php
class Select_Model extends CI_Model{
public function get_data(){
if($this->input->post('submit')){
$value = array('country' => $this->input->post('country'),
'state' => $this->input->post('state'),
'city' => $this->input->post('city')
);
$query = $this->db->get_where('tablename', $value);
return $query;
}}}?>
我也在這里添加我的控制器代碼-
class Select_Ctrl extends CI_Controller {
public function index()
{
$this->load->model('Select_Model');
$data['val'] = $this->Select_Model->get_data();
$this->load->view('form',$data);
}}?>
您的查詢是正確的,只是這樣返回。result_array result_array()
以數組格式返回結果。對於對象格式,請使用result()
代替result_array()
。
<?php
class Select_Model extends CI_Model{
public function get_data(){
if($this->input->post('submit')){
$value = array('country' => $this->input->post('country'),
'state' => $this->input->post('state'),
'city' => $this->input->post('city')
);
$query = $this->db->get_where('tablename', $value);//not dbname there must be name of your table
return $query->result_array();
}}}?>
要么
<?php
class Select_Model extends CI_Model{
public function get_data(){
if($this->input->post('submit')){
$this->db->where('country',$this->input->post('country'));
$this->db->where('state',$this->input->post('state'));
$this->db->where('city',$this->input->post('city'));
$query = $this->db->get('tablename');
return $query->result_array();
}}}?>
您可以將以下代碼用於多個用戶定義的where子句。
<?php
class Select_Model extends CI_Model
{
public function get_data()
{
if($this->input->post('submit'))
{
$this->db->where('country' => $this->input->post('country'));
$this->db->where('state' => $this->input->post('state'));
$this->db->where('city' => $this->input->post('city'));
$query = $this->db->get('tablename');
return $query->result();
}
}
}
?>
從手冊
$ this-> db-> get_where()
與上面的函數相同,除了它允許您在第二個參數中添加“ where”子句,而不是使用db-> where()函數:
$query = $this->db->get_where('mytable', array('id' => $id), $limit, $offset);
請閱讀以下有關where功能的信息。
