            $data['search'] = $this->Fetch_data->autocomplete($searchTerm);
            $this->load->view('index',$data);

    $(function() {
        $( "#colleges" ).autocomplete({
            source: '<?php echo base_url("index.php"); ?>/test/index';
        });

model：Fetch_data.php

<?php

        {
            $this->db->select('college_name,field');
            $this->db->from('all_colleges');
            $where = "short_name like '%".$searchTerm."%' or college_name like '%".$searchTerm."%'";
            $this->db->where($where);
            $this->db->order_by('college_name');
            $query = $this->db->get();
            $result = $query->result_array();
            return $result;
        }
    }

我是ci的新人。使用此代码我想在codeigniter中创建一个自动完成建议框但是这段代码对我不起作用。那么，如何在ci中创建自动完成建议框，请告诉我我的代码中有什么问题可以使用此代码进行自动完成。

谢谢

更新您可以尝试：

你的模特 Fetch_data.php

<?php  
class Fetch_data extends CI_Model  
{  
    function __construct()  
    {   
        parent::__construct();  
    }  
    public function autocomplete()
    {
        $this->db->select('college_name,field');
        $this->db->from('all_colleges');
        $this->db->order_by('college_name');
        $query = $this->db->get();
        $result = $query->result_array();
        return $result;
    }
}

控制器： Test.php

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Test extends CI_Controller 
{
    function __construct() 
    {
        parent :: __construct();
        $this->load->helper(array('form', 'url'));
        $this->load->model('Fetch_data');
    }
    public function index()
    {
        $all_data = array();
        $result  = $this->Fetch_data->autocomplete(); //collect all college name
        foreach($result as $key=>$value){
           array_push($all_data, $value["college_name"]);
        }

        $data['search'] = $all_data;
        $this->load->view('index',$data);          
    }
}

查看： index.php

<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>

<input type="text" name="colleges" id="colleges" class="form-control" />
<input type='hidden' id='mydata' value='<?php echo json_encode($search);?>' />
<script>

    $( function() {
       var oData = $("#mydata").val();
           oData = JSON.parse(oData);
       $( "#colleges" ).autocomplete({
          source: oData;
       }); 
    });
</script>

您可以获取所有的college_names并使用变量存储它，然后当您输入一个字母时，您不能再使用ajax，因为它已经存储了变量。

希望它能奏效。
