Fetching data from MYSQL using Autocomplete no result found

Question

I want a searching like the one in Google. When you start typing there will be suggestions listed in a dropdown so I used autocomplete. My problem is when i type any key the output is "No result found" even though the data that I'm typing is in my database. I check my database connection and its right. Can someone explain to me what I'm doing wrong?

HTML

   <input type="text" name="clientname" id="clientname" />

php This part is editted, i tried the suggestion of @asik but still not working

filename:getautocomplete.php

   if (isset($_REQUEST['term'])){
$return_arr = array();

    $stmt = $con->prepare('SELECT * FROM client WHERE CLIENTNAME LIKE :term');
    $stmt->execute(array('term' => '%'.$_GET['term'].'%'));
    while($row = mysqli_fetch_assoc($stmt)) {
        $return_arr[] =  $row['CLIENTNAME'];            
    }
    echo json_encode($return_arr);
        }
        else
        {
     echo 'ERROR: ' . $e->getMessage();
    }

JavaScript

    $(function() {
      $("#clientname" ).autocomplete({
      source: "getautocomplete.php"
   });
  });

thanks in advance

Answer 1

try this, you are missing : in named param

$stmt = $con->prepare('SELECT CLIENTNAME FROM client WHERE CLIENTNAME LIKE :term');
$stmt->execute(array(':term' => '%'.$_REQUEST['term'].'%'));

Hope this works, if not you can try formatting the response as label & value

$return_arr[] =  array('label' => $row['CLIENTNAME'], value => $row['CLIENTNAME']);  

still not working post screenshot of getautocomplete.php response using Firebug
