We are experiencing an issue when an invalid url is passed to cake. This loads the missing_controller.ctp view correctly but $_SESSION variable is empty.
We have tested this on 1.3 and 2.0 and in both version $_SESSION is empty when the missing_controller view is rendered.
Is this done on purpose?
Thanks
Regards
Gabriel
Did you imported the Session component in Controller? Like this:
<?php
class MissingController extends AppController{
var $components = array('Session');
var $helpers = array('Session');
}
Try to access the data in $_SESSION with $this->Session->read('This.That');

In my project, image need to upload and crop. So, I have taken help from http://bakery.cakephp.org/articles/klagoggle_myopenid_com/2010/08/25/jquery-image-upload-crop
By this instruction I have created file jq_imgcrop.php and with code saved it in app/controllers/components and also created cropimage.php and saved it app/views/helpers
after that I add the component and the helper in my controller where I want to use the cropload.
code given below
App::uses('AppController', 'Controller');
App::uses('BarcodeHelper','Vendor');
/**
* OesUsers Controller
*
* #property OesUser $OesUser
*/
// set the default timezone to use. Available since PHP 5.1
class OesUsersController extends AppController {
var $helpers = array('cropimage');
var $components = array('jq_imgcrop');
After saved, it is giving me a error that is "Missing Component!!"
In this define directory, have I made any mistake?
The article in the link is written in cakephp 1.x.
I'm still trying to migrate from CakePHP 1.3 to 2.0
I have a Controller UsersController and its Model User.
The class User has some constants which I could easily access from the UsersController using User::constant. But for CakePHP 2.0 it doesn't work: I get an error saying the User class is not found. It works if I App::Import('Model', 'User');.
It sure has to do with their built-in lazy loading in 2.0!
you simple need to tell this file that it has other dependencies
do that at the very top of your UserController file:
<?php
App::uses('User', 'Model');
then everything works fine
You can try setting the controller name (in UsersController):
var $name = 'Users';
Or using the "uses" var (in other controllers:
public $uses = array('User');
Does that not work?
Did you declare the name of the model like that ?
class User extends AppModel {
public $name = 'User';
}
Do you have others variables in your UsersController ?
I set variables in the model like this:
//Person model
public $genders = array('m' => 'male', 'f' => 'female');
Then get them from the controller like this:
//People controller
$genders = $this->Person->genders;
No special code needed. (Is this what you're talking about?)
Also, I don't believe you need to set the $name variable anywhere anymore - I think that was just for PHP 4. (not 100% on that part, but... I don't ever set that anymore, and my Cake2 apps run fine)
You have to load the model like this:
$this->loadModel('User');
I've get this message when I tried to use a wrong controller and I figured it out that I'm not getting the right Error from cakephp I've got in 2.0.0 the right one:
Now when I try a wrong controller I get only this message:
Fatal error: Call to a member function Flash() on a non-object in
/srv/www/htdocs/web843/HTML/schaetzmal/lib/Cake/View/Layouts/default.ctp
on line 44
Does cakephp 2.0.3 have an bug or do I miss something to install to let work this or something else what I can do?
Make sure you've added the Session helper to your public $helpers array.
class SomethingsController extends AppController {
public $helpers = array('Session');
}
Or you could add it to a global AppController so that the Session helper is available to all controllers.
class AppController extends Controller {
public $helpers = array('Session');
}
I found some problems why my AppController didn´t work.
Like mensch says i have to use Session in my AppController for global but that´s not the solution because the book of cakephp says in "a global AppController"
NOTE
CakePHP merges the following variables from the AppController to your application’s controllers:
$components
$helpers
$uses
but it´s not happening. Because i overwrite it in the public variable $helpers.
therfore i take the parent given one and merge it with it:
<?
class AppController extends Controller {
public $viewClass = 'Theme';
public $theme;
public function beforeFilter() {
parent::beforeFilter();
$this->theme = 'SM';
$this->helpers = array('Form','Html','Js');
}
}
?>
the $this->helpers = array('Form','Html','Js'); do the merge and it works fine.
thank you guys
thanks for helping mensch that was the hack i needed
I'm new to cakePhp development. I've stuck on following problem:
I've made few models, controllers and views - it works great. The problem is that after production, I have to made new table(Transactionaltemp table and corresponding model and controller ) in the db that logically is "connected" to other tables, but technically does not needs to - for ex. it holds temporary info on user_id, time, ip and similar. So, other tables doesn't need to be directly connected to that.
The problem is when I try (in some other controller than transactionaltemps_controller):
$this->loadModel('Transactionaltemp');
I get error - the model is not found (it is true because the model is missing in the cache). Interesting enough transactionaltempls_controller is in the cache (in the cake_controllers_list file).
I tried following stuff to resolve the problem:
clear cache
disable cache
tried using uses={..} code in the controller that I would like to use mymodels_controller
tried using init('Transactionaltemp')
with no success. Here is corresponding code:
The model:
<?php
class Transactionaltemp extends AppModel
{
var $name = 'Transactionaltemp';
function beforeSave() {
return true;
}
}
?>
The controller:
<?php
class TransactionaltempsController extends AppController
{
var $name = 'Transactionaltemps';
var $scaffold;
}
?>
I'll very grateful to any help!!!
App:Import('Model','Transactionaltemp');
$this->Transactionaltemp= new Transactionaltemp;
I hope this may work
If you are connecting to a table name with different name than your model, you must specify the table name in it:
<?php
class Transactionaltemp extends AppModel
{
var $uses = 'Transactional';
var $name = 'Transactionaltemp';
function beforeSave() {
return true;
}
}
Try
App::Import('Model', 'YourModelName');
in your controller (or where you want).
i don't want to add it as below cause i needed them only once in certain action method
(so do not useless load the memory)
class UsersController extends AppController {
var $name = 'Users';
var $helpers = array('Html', 'Session');
var $components = array('Session', 'Email');
class UsersController extends AppController {
public function method_name() {
$this->helpers[] = 'MyHelper'
}
}
More on this in the documentation.
Hope that helps.
You can load helpers using
$this->helpers[] = 'MyHelper';
as Rob mentioned above, but this won't work for controllers because they have their initialize and startup methods that need to be called in order for them to work.
I've come across a bit of code on the web for loading components inside of a controller action: ComponentLoaderComponent
Yes, it is a component but it isn't very big so it shouldn't be a problem to include it in your controllers.
Either that or you can just study it to see how the component loading works and then write your own controller action to do the same.
I use a component for adding helpers and components on the fly:
$this->Common->addHelper('Tools.Datetime');
$this->Common->addHelper(array('Text', 'Number', ...));
$this->Common->addComponent('RequestHandler');
$this->Common->addLib(array('MarkupLib'=>array('type'=>'php'), ...));
etc
The complete code to this can be seen in the cakephp enhancement ticket I just opened:
http://cakephp.lighthouseapp.com/projects/42648-cakephp/tickets/1277
Or with php markup:
http://www.dereuromark.de/2010/11/10/loading-classes-on-the-fly/
It also fixes some minor problems with the solution posted by mtnorthrop.
Plugins as well as passed options are now possible. Have fun.
