Timezones

2012-02-13T17:51:24+00:00

Hello,

I would like to use the CI function timezone_menu() contained in the Date/Time helper but I saw it contain a serious error: it lists Warsaw as GMT +2:00 when it is actually inside +1:00 zone. Did you check all zones or just made a copy and paste from an untrusted source?

As an European citizen I cannot use in my website such a function, because it proves to be not accurate. If it does not list properly an European country how can I be sure it is accurate with less known (but not less important) countries around the world?

Roberto

Email issue - Q prep for header

2012-02-13T16:28:33+00:00

Using utf-8 / html format with the Email library, a space is added on the subject

$this->CI->load->library(‘email’);
$this->CI->email->set_mailtype(“html”);
$this->CI->email->from($fromAddress, $fromName);
$this->CI->email->to($toAddress);
$this->CI->email->reply_to($replyToAddress, $replyToName);
//Envoi d’un header supplémentaire avec le nom
//$this->CI->email->subject($subject); //Bug add space un the subject !!!
$this->CI->email->_headers[‘Subject’]= $subject; //I had to do this UGLY thing !!!
$this->CI->email->message($bodyHTML);
$result=$this->CI->email->send($this->CI->config->item(‘msg_success’));

It seems that the issue is in Email.php:
public function subject($subject)
{
$subject = $this->_prep_q_encoding($subject);
$this->_set_header(‘Subject’, $subject);
return $this;
}

In the final mail, I get
Subject: =?utf-8?Q?Chanel_et_RABE_REGIS_vous_invitent_=c3=a0_d=c3=a9couvrir_un_co ?= =?utf-8?Q?ntenu_chanel_makeup_confidential?=
Instead of :
Subject: =?utf-8?Q?Chanel_et_RABE_REGIS_vous_invitent_=c3=a0_d=c3=a9couvrir_un_contenu_chanel_makeup_confidential?=

It seems that it adds a new line after 75-7-5 chars

Email issue - Return Path

2012-02-13T15:52:46+00:00

Why CI forces the Return-path = From ?

Because in case of a backend service that send the mail through a sharing, The from is the sender mail, the Return-Path must be the server’s mail so it could matche the smtp => avoid blacklisting.
The main goal is to have sender’s address via mailer host and the reply-to to the sender’s mail.

Session Library not loading in MY_Controller… even though it should be autoloaded.

2012-02-13T03:57:17+00:00

I need help with this one. It seems that the Session Library isn’t loading properly inside MY_Controller.php and I have no idea why. I get an extremely strange error that I can not seem to figure out when I try to load a function that does not exist inside a public controller that does exist. For example, http://www.mysite.com/welcome/alskdjfas will throw the error (the welcome controller exists, but that function doesn’t). The Welcome controller does exist, but the “alskdjfas” function does not.

The errors say:

A PHP Error was encountered

Severity: Notice

Message: Undefined property: Welcome::$session

Filename: core/MY_Controller.php

Line Number: 14

Fatal error: Call to a member function userdata() on a non-object in C:\xampp\htdocs\websites\diftx\dol\application\core\MY_Controller.php on line 17

I don’t see what I am doing wrong because the Welcome controller extends MY_Controller, and that extends CI_Controller.

<?php

class MY_Controller extends CI_Controller
{
 var $user = FALSE;
 
 protected $layout_view = 'main';
 protected $content_view = '';
 protected $view_data = array();
 
 function __construct()
 {
  parent::__construct();
  $this->user = $this->session->userdata('USER_ID') ? User::find_by_id($this->session->userdata('USER_ID')) : FALSE;
 }
 
 function _output($output)
 {
  //set the default content view
  if($this->content_view !== FALSE && empty($this->content_view)) $this->content_view = $this->router->class . '/' . $this->router->method;
  
  //render the content view
  $yield = file_exists(APPPATH . 'views/' . $this->content_view . EXT) ? $this->load->view($this->content_view, $this->view_data, TRUE) : FALSE;
  
  //render the layout
  if($this->layout_view)
   echo $this->load->view('layouts/' . $this->layout_view, array('yield' => $yield), TRUE);
  else
   echo $yield;
 }
} 

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Welcome extends MY_Controller {
 
 function __construct()
 {
  parent::__construct();
 }
 
 function index()
 {
 }
 
 function not_found()
 {
 }
} 

They are extended properly (to my knowledge) and both call the constructors of the class that they extend in their own constructors with “parent::__construct()”.

The Session Library is autoloaded and I use it throughout my application flawlessly but it doesn’t seem to be loading in this instance, which is causing PHP errors in my application, and attempting to load the Session Library manually before where the error occurs is not fixing the problem.

My application is giving this error instead of displaying the 404 page like it should be doing. This ONLY happens when I try to load a function inside a controller that doesn’t exist. The page displays the 404 page as expected if I’m trying to load a controller that doesn’t exist. Only the function that doesn’t exist is causing the PHP Fatal Error to happen.

CodeIgniter_2.1.0 for a complete novice!

2012-02-12T22:46:50+00:00

hey

I have got a background in programming but I wouldn’t say I’m at a professional level by any standard! I’ve been working with wordpress and I can modify it to meet my needs, but I still feel I dont have complete control over it.

I was introduced to CI by a friend(who is not using CI, but is looking into it) and I watched the tutorials on this website and was completely blown away with the basic capabilities, so I downloaded it and set it up on wamp. I later set it up on my server (linux).

I have a nack for getting excited about learning something new or trying out new technologies and hitting a dead-end right away with the very basics, but once i get over those hurdles I can pick up the slack.

Basically, the tutorials that are on CI.com dont match up with 2.1.0. It is something simple like the new directory layout, and the fact that the default screen is welcome.php. What ever the case may be, following the tutorials are not really possible because of this.

I dont really know where to start with using it. I tried just going along with the tuts but no joy, 403 errors. I created index.php, changed the default controller to index.php, then tried the blog post and I’m now getting a white screen(some progress?). Even hello world wont load!

Does anyone know of a tutorial for 2.1.0 that goes litterally step by step through achieving even just hello world?

I’m confident its not the server setup, it has to be a step I’m missing out on.

Any input would be greatly appreciated!

Regards

myself!

Forcing CSRF on a form

2012-02-12T19:24:37+00:00

My site is deployed over multiple domains and the form_open function in the form_helper only forces csrf protection when you are posting to the same site_url. Although this might be wanted behavior in some situations it might be useful to generate the csrf token. The form_open function should have a way to force the csrf token . I know we can easily do this by using an hidden array ourselves but the code for the csrf generation is already in the form helper. I suggest to add an option to this helper function like

if ( ! function_exists('form_open'))
{
 function form_open($action = '', $attributes = '', $hidden = array(), $force_csrf = false)
 {
  $CI =& get_instance();

  if ($attributes == '')
  {
   $attributes = 'method="post"';
  }

  // If an action is not a full URL then turn it into one
  if ($action && strpos($action, '://') === FALSE)
  {
   $action = $CI->config->site_url($action);
  }

  // If no action is provided then set to the current url
  $action OR $action = $CI->config->site_url($CI->uri->uri_string());

  $form = '<form action="'.$action.'"';

  $form .= _attributes_to_string($attributes, TRUE);

  $form .= '>';

  // Add CSRF field if enabled or when forced, but leave it out for GET requests and requests to external websites 
  if ($CI->config->item('csrf_protection') === TRUE AND ! (strpos($action, $CI->config->site_url()) === FALSE OR strpos($form, 'method="get"')) OR $force_csrf) 
  {
   $hidden[$CI->security->get_csrf_token_name()] = $CI->security->get_csrf_hash();
  }

  if (is_array($hidden) AND count($hidden) > 0)
  {
   $form .= sprintf("<div>%s</div>", form_hidden($hidden));
  }

  return $form;
 }
}

CI with MySQL client library 4.1.11 bug, mysql_set_charset does not exist resulting in blank pages

2012-02-12T10:03:00+00:00

I think there is a bug in the mysql_driver.php file.

On my server, I was finding that when I loaded the database I got nothing but blank pages. Eventually, I pinpointed the problem to line 150 in mysql_driver.php, within the db_set_charset() method:


return @mysql_set_charset($charset, $this->conn_id);

The error suppression was hiding the fact that mysql_set_charset() is not defined.

According to documentation in the db_set_charset() method, the mysql_set_charset() function is used when PHP >= 5.2.3 and MySQL >= 5.0.7. When these conditions aren’t met it falls back to SET NAMES.

My server is using MySQL server version 5.0.45 and PHP 5.2.4, so it passes this test. However, it is using version 4.1.11 of the MySQL client library, which doesn’t support mysql_set_charset(). I found this information here: http://www.php.net/manual/en/function.mysql-set-charset.php#80997
