Question

我的网站上有一张表格可以提交一只猫。表单包含“名称”和“性别”等输入，但我只是尝试使用“名称”字段进行自动完成。这是我的jquery的样子：

$(document).ready(function() {
$( "#tags" ).autocomplete({
source: '/Anish/auto_cat'
});
});

以下是我的模型：

  public function auto_cat($search_term) {
    $this->db->like('name', $search_term);
    $response = $this->db->get('anish_cats')->result_array();
    // var_dump($response);die;
    return $response;
  }
}

这是我的控制器：

public function auto_cat(){
  $search_term = $this->input->get('term');
  $cats = $this->Anish_m->auto_cat($search_term);
}

以下是我的观点：

          </form>
        </td>
      </tr>
      <?php endforeach;?>
    </tbody>
  </table>

我被困住了。在我的控制台中，如果我在模型中取消注释var_dump，当我键入字母'a'时，我能够看到此输出：

array(4) {
  [0]=>
  array(9) {
    ["id"]=>
    string(2) "13"
    ["name"]=>
    string(5) "Anish"
    ["gender"]=>
    string(4) "Male"
    ["age"]=>
    string(2) "20"
    ["species"]=>
    string(3) "Cat"
    ["eye_color"]=>
    string(5) "Brown"
    ["color"]=>
    string(5) "Black"
    ["description"]=>
    string(7) "Awesome"
    ["marital_status"]=>
    string(1) "0"
  }
  [1]=>
  array(9) {

如果有帮助的话，试试这个：

<?php
    #controller function
    public function auto_cat(){
        print_r ( $this->model->search_auto_cat($_REQUEST['term']) );
    }

    #model function
    function search_auto_cat($term){
        $data   = array();
        $rs     = $this->db->select('name as label, name as value, id', false)->or_like('name', $term)->or_like('last_name', $term)->or_like('id', $term)->limit(20)->get('anish_cats');
        //print_r($this->db->last_query());
        if($rs->num_rows() > 0 ){
            $temp   = $rs->result_array();
        }else{
            $temp   = array();
            $temp[0]['label']  = "No results found";
            $temp[0]['value']  = "";
            $temp[0]['id']     = "0";

        }
        $data   = json_encode($temp);
        return $data;
    }
?>

Answer 2

这意味着它正在运行，但问题是您只需要来自一列的数据。所以在模型中

public function auto_cat($search_term) {
$this-db->select('name'); 
$this->db->like('name', $search_term);
$response = $this->db->get('anish_cats')->result_array();
// var_dump($response);die;
return $response;
 }

}

并在控制器中。

public function auto_cat(){
      $search_term = $this->input->get('term');
     $cats = $this->Anish_m->auto_cat($search_term);
      print json_encode($cat);
}

我希望这会有助于你的答案。
