CaptainChainsaw Posted October 23, 2009 Share Posted October 23, 2009 Hi all, I'm new to Kohana and JQuery but I think my problem should be easy to fix. What I want to do is dynamically check the database for usernames as soon as a user starts inputting a character, so I'm using the JQuery method .keyup for that. The data is getting passed to the javascript as I can pass it to the alert() function and it is displayed as I expect it. However the data doesn't appear on the webpage as I type it, its only printed on the page when the submit button is clicked. I want it to display when it is submitted and on keyup. Any ideas? Here's the "view": <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html> <head> <script src="/application/views/jquery-1.3.2.min.js" type="text/javascript" charset="utf-8"></script> <script type="text/javascript" src="/application/views/jquery.form.js"></script> <script type="text/javascript" charset="utf-8"> $(document).ready(function(){ $('#username').keyup(function(){ sendValue($(this).val()); }); }); function sendValue(str){ // alert('sending value: '+str); // $.post("/index.php/user/create.php",{ sendValue: str }, $.post("/application/controllers/user.php",{ sendValue: str }, //$.post("create.php",{ sendValue: str }, function(data){ $('#username').html(data.returnValue); }, "json"); } </script> <?php echo html::stylesheet(array ( 'assets/css/style' ), array ( 'screen' ), FALSE); ?> <title>Registration</title> </head> <body> <?php echo form::open('user/create'); ?> <table class='editor'> <tr> <td colspan='2' class='editor_title'>Register</td> </tr> <tr> <td></td> </tr> <?php echo "<tr>"; echo "<td>".form::label('username', 'Username: ')."</td>"; //echo "<td>".form::input('username', '')."</td>"; echo '<td><input type="text" name="username" id="username" /></td>'; echo "<td> <div id=\"username\"></div></td>"; echo "</tr>"; echo "<tr>"; echo "<td colspan='2' align='left'>".form::submit('submit', 'Register')."</td>"; echo "</tr>"; ?> </table> <?php echo form::close(); ?> </body> </html> Here's the "controller": <?php defined('SYSPATH') OR die('No direct access allowed.'); class User_Controller extends Controller { private $user_model; private $createuser_view; public function __construct() { parent::__construct(); $this->user_model = new User_Model; $this->createuser_view = new View('createuser'); } public function index() { $this->createuser_view->render(TRUE); } public function create(){ $user_data=array( 'username' => $this->input->post('username') ); $db_users_list = $this->user_model->findByUsername($user_data['username']); if(sizeof($db_users_list) == 0){ echo json_encode(array("returnValue"=>"This is returned from PHP : ".$user_data['username'])); }elseif(sizeof($db_users_list) == 1){ $this->user_model->create($user_data); url::redirect('user'); } } } Link to comment https://forums.phpfreaks.com/topic/178790-solved-kohana-framework-with-jquery-issue/ Share on other sites More sharing options...
trq Posted October 23, 2009 Share Posted October 23, 2009 $('#username').html(data.returnValue); Would replace the entire form element with your value, you need to use the val() method. eg; $('#username').val(data.returnValue); Also, I'm not a kohuna user, but it looks to me like your uri ought to be.... /application/controllers/user/create And within that method you should be looking for your data within... 'username' => $this->input->post('sendValue') Link to comment https://forums.phpfreaks.com/topic/178790-solved-kohana-framework-with-jquery-issue/#findComment-943178 Share on other sites More sharing options...
CaptainChainsaw Posted October 25, 2009 Author Share Posted October 25, 2009 Hi thorpe, Thanks again for your help, much appreciated! Turns out that the following line was actually ok: $('#username').html(data.returnValue); Anyway I've got it working now, my first proper AJAX!
