php - Codeigniter Autocomplete search box with JSON, MySql -


i'm trying make autocomplete search box code doesn't work, i'm trying 3 days. need autocomplete search result system. have tried several ways. in view, don't response or error. after typing 1 letter doesn't tell anything

code on controller

<?php if ( ! defined('basepath')) exit('no direct script access allowed');  class search extends ci_controller { function __construct() {     parent::__construct(); } public function index() {     $this->load->view('search'); }  public function getfunction() {  if ( !isset($_get['term']) )  exit;  $term = $_request['term'];     $data = array();     $rows = $this->model_search->getdata($term);         foreach( $rows $row )         {             $data[] = array(                 'label' => $row->bname.', '. $row->bname,                 'value' => $row->bname);          }     echo json_encode($data);     flush();  } }

and model code is

<?php if ( ! defined('basepath')) exit('no direct script access allowed'); class model_search extends ci_model { public function __construct() {      parent::__construct();      // own constructor code  } function getdata($term) {      $sql = $this->db->query('select * brands bname "'. mysql_real_escape_string($term) .'%" order bname asc limit 0,10'); return $sql ->result();  }  }

view code is;

    <html lang="en-us">       <head>           <title>codeigniter autocomplete</title>           <link rel="stylesheet" href="<?php echo base_url('assets/css/jquery-ui.css'); ?>" type="text/css" media="all" />           <script src="<?php echo base_url('assets/js/jquery-ui.js'); ?>" type="text/javascript"></script>           <script src="<?php echo base_url('assets/js/jquery-1.8.3.js'); ?>" type="text/javascript"></script>           <meta charset="utf-8">     <script type="text/javascript"> $(document).ready(function(){ $(function() { function split( val ) {             return val.split( /,\s*/ );     }             function extractlast( term ) {              return split( term ).pop();     }      $( "#txtinput" )         // don't navigate away field on tab when selecting item           .bind( "keydown", function( event ) {             if ( event.keycode === $.ui.keycode.tab &&                     $( ).data( "autocomplete" ).menu.active ) {                 event.preventdefault();             }         })         .autocomplete({             source: function( request, response ) {                 $.getjson( "<?php echo base_url();?>search/getfunction",{                       term: extractlast( request.term )                 },response );             },             search: function() {                 // custom minlength                 var term = extractlast( this.value );                 if ( term.length < 1 ) {                     return false;                 }             },             focus: function() {                 // prevent value inserted on focus                 return false;             },             select: function( event, ui ) {                 var terms = split( this.value );                 // remove current input                 terms.pop();                 // add selected item                 terms.push( ui.item.value );                 // add placeholder comma-and-space @ end                 terms.push( "" );                 this.value = terms.join( "," );                 return false;             }         });  }); }); </script>                    </head>       <body>   <input type="text" id="txtinput" size="20" />         </body>   </html>
