so... I basically follow the practical symfony book, and encountered following problem.
I have properly (i guess) installed sfGuardPlugin, built the models, sqls etc, created user and tried to log in with the username and password entered.
i got the following error message:
Fatal error: Call to undefined method sfGuardUserPeer::retrieveByUsername() in /***/plugins/sfGuardPlugin/lib/validator/sfGuardValidatorUser.class.php on line 53
it looks quite weird to me, because the problematic part of sfGuardValidatorUser class looks like this:
// user exists?
if ($user = sfGuardUserPeer::retrieveByUsername($username))
{
// password is ok?
if ($user->getIsActive() && $user->checkPassword($password))
{
return array_merge($values, array('user' => $user));
}
}
while sfGuardUserPeer has just the empty class:
class sfGuardUserPeer extends PluginsfGuardUserPeer
{
}
that extends PluginsfGuardUserPeer, so i checked it out too:
class PluginsfGuardUserPeer extends BasesfGuardUserPeer
{
public static function retrieveByUsername($username, $isActive = true)
{
$c = new Criteria();
$c->add(self::USERNAME, $username);
$c->add(self::IS_ACTIVE, $isActive);
return self::doSelectOne($c);
}
}
that's the missing function!
so - what is wrong? why doesn't it work?
i have already tried all the solutions found with google, but none of them work :/
finally found it!
the
symfony propel:build-model
task unnecessarily generated the sfGuard classes in the model directory from the schema file located in the plugin directory, while all the classes were already present in the sfGuard folder.
geez, that shouldn't happen in such a well-developed framework and plugin...
Simply put that
public static function retrieveByUsername($username, $isActive = true)
{
$c = new Criteria();
$c->add(self::USERNAME, $username);
$c->add(self::IS_ACTIVE, $isActive);
return self::doSelectOne($c);
}
Code into your sfGuardUserPeer class, this will sort out the issue, I did the same when I got this error, it worked for me..

I doing tutorial follow http://book.cakephp.org/3.0/en/development/errors.html#exception-renderer but it is not working and display blank page.
In config/bootstrap.php
use App\Error\AppError;
$errorHandler = new AppError();
$errorHandler->register();
In src/Error/AppError.php
<?php
namespace App\Error;
use Cake\Error\BaseErrorHandler;
class AppError extends BaseErrorHandler
{
public function _displayError($error, $debug)
{
return 'There has been an error!';
}
public function _displayException($exception)
{
return 'There has been an exception!';
}
public function handleFatalError($code, $description, $file, $line)
{
return 'A fatal error has happened';
}
}
I create my_error.ctp in src/Template/Layout/my_error.ctp. And in my src/Template/Error/error404.ctp I change layout to my_error.ctp.
$this->layout = 'my_error';
Finally, In my controller
use Cake\Network\Exception\NotFoundException;
$staff = $this->Staff->find()->where(['Staff.StaffId = '=> $id, 'Staff.PartnerId = ' =>$this->partnerId])->first();
if (empty($staff)) {
throw new NotFoundException(__('Staff not found'));
}
Whenever encountering blank pages, enabled debug mode, visit the URL again, and check your error logs.
However, problem in this case is most likely that the docs are incorrect/misleading, as the example app error won't do anything at all. The _ prefixed methods are ment to be protected, having them return something has no effect, and handleFatalError is ment to return a boolean.
Just look at the source of Cake\Error\BaseErrorHandler and the core error handler Cake\Error\ErrorHandler, the methods that you are overwriting are ment to generate output!
You may want to report that as an issue over at GitHub.
If all you want to do, is create a custom 4xx error page, then all you need to do is to edit the src/Template/Error/error400.ctp template accordingly.
I found my mistake. :(
Because in bootstrap.php I copy below code at the end of file. Therefore Cake cannot understand it. Please close this issue. Thank you for support.
use App\Error\AppError;
$errorHandler = new AppError();
$errorHandler->register();
I'm trying to write an external library which has functions commonly used among various classes.
Currently I'm trying to write a log message function. The problem is I need access to the session library and a model. How do I access them without extending from CI_Controller? Any workaround?
Here's my code:
Common_functions library:
public function _send_message($message, $log_to_db=TRUE)
{
$this->session->set_userdata("message", $message);
if($log_to_db) $this->User_log_model->log_mesage($message);
}
Usage in other classes example:
public function new_user()
{
$this->_set_validation_rules();
if($this->form_validation->run())
{
if($user_id = $this->User_model->insert($this->_prepare_new_user_array()))
{
$this->common_functions->_send_message("New User created successfully. | user_id: " . $user_id);
}
else {
$this->common_functions->_send_message("Unable to create new User record.");
}
}
}
Managed to solve it. Just moved my log message functions to the User_log_model instead.
I just downloaded CakePHP and was following the tutorials to get the basics. Everything was going ok, until I started with this Authentication system.
If you go to the following url, and to the password hashing block ( of code ).
http://book.cakephp.org/2.0/en/tutorials-and-examples/blog-auth-example/auth.html#authentication-login-and-logout
you will see:
public function beforeSave($options = array()) {
if (isset($this->data[$this->alias]['password'])) {
$passwordHasher = new BlowfishPasswordHasher();
$this->data[$this->alias]['password'] = $passwordHasher->hash(
$this->data[$this->alias]['password']
);
}
return true;
}
The issue is when I run this, is that I get a Fatal Error on that Line:
Fatal error: Class 'BlowfishPasswordHasher' not found in /Users/myUser/Sites/cake/app/Model/User.php on line 29
This is the line (to be precise):
$passwordHasher = new BlowfishPasswordHasher();
Why isn't it seeing that file ?
In my PHPStorm IDE, when I alt+click on it, it goes to the correct file located in:
/Users/myUser/Sites/cake/lib/Cake/Controller/Component/Auth/BlowfishPasswordHasher.php
Anyone else having issues with this ?
Thanks in advance
Put following line in your User Model
App::uses('BlowfishPasswordHasher', 'Controller/Component/Auth');
class User extends AppModel {
....
}
Note : The BlowfishPasswordHasher uses a stronger hashing algorithm (bcrypt) than SimplePasswordHasher (sha1) and provides per user salts. The SimplePasswordHasher will be removed as of CakePHP version 3.0
I hope someone can help me with this one before I jump off the window. I spent few hours on this one and don't know what am I doing wrong.
Basically, I've installed HMVC in CodeIgniter 2.1.2 and everything works fine, BUT for some reason I can't load models the same way I'm doing it in standard controllers. In the old codeigniter 1.7.1 I could use it simply by invoking $this->load->model('my_model') but now I can't?!
Every single time I'm trying to load model I get this error:
A PHP Error was encountered
Severity: Notice
Message: Undefined property: Special_cart::$db
Filename: core/Model.php
Line Number: 51
I have had installed it step-by-step according to the instructions. I got third_party next to modules folder. In modules I have few modules stored like this:
modules
--boxes
----controller
----models
----views
I invoke module in my code like this:
<?=modules::run('boxes/special_cart/index');?>
My module controller code looks like this:
class Special_cart extends CI_Controller
{
public function __construct()
{
parent::__construct();
}
public function index()
{
if ($this->session->userdata('cart'))
{
# get product id's and each quantity
$cart_product_list = array_count_values($this->session->userdata('cart'));
# get list of product_id
$product_list = array_keys($cart_product_list);
# get product details
$this->load->model('productmodel');
$this->load->model('stockmodel');
$cart_products = $this->productmodel->cart_get_products_details($product_list);
$final_cart_array = array();
foreach($cart_products as $cart_product){
$product_stock = $this->stockmodel->view_product_stock($cart_product["id"]);
if(empty($product_stock) || $product_stock["UNITS"]<=0)
$cart_product["UNITS"] = 0;
else{
if($cart_product_list[$cart_product["id_web"]]>$product_stock["UNITS"])
$cart_product["UNITS"] = $product_stock["UNITS"];
else{
$cart_product["UNITS"] = $cart_product_list[$cart_product["id_web"]];
}
}
$final_cart_array[] = $cart_product;
}
$refresh_cart_array = array();
foreach($final_cart_array as $cart_product){
for($i=1;$i<=$cart_product["UNITS"];$i++){
$refresh_cart_array[] = $cart_product["id_web"];
}
}
$this->load->view("special_cart",array(
'refresh_cart_array' => $refresh_cart_array,
'final_cart_array' => $final_cart_array
));
} else {
$this->load->view("special_cart",array(
'refresh_cart_array' => NULL,
'final_cart_array' => NULL
));
}
}
}
I've tried every possible solution found on internet - none of them work....
I hope you understand my problem but in case you need some further explanation please ask me. Can anyone help?
Looks like the model you're trying to load wants to connect to the db, but the database driver is not available. If you use database queries in your application, why don't you load the database driver automatically?
Just insert "database" in the "libraries" array in application/config/autoload.php file. Don't forget to insert your database credentials into application/config/database.php.
$autoload['libraries'] = array('database');
If you need database connection just in one single model, load it before trying to access database library.
$this->load->database();
Try loading the model stating the module name as follows
$this->load->model('module_name/productmodel');
Class Models extends MX_Loader{
function getUser($username){
$sql="SELECT * FROM user WHERE username = ? ";
return $this->db->query($sql,array($username))->row();
}
}
you must using extends MX_Loader because i don't know if using CI_Model the database core cant be load in Codeigniter,,,
Try to use extend MX_Controller class (not CI_Contoller like you are doing atm)
Based on what you have wrote in comment above, I figured that you tried to create new instance of DB in module (based on chrises comment).
Do it on constuctor of Special_cart
So update current construct to be like
public function __construct()
{
parent::__construct();
$this->load->database('default');
}
(I'm writing this from top of my head, so check the methods)
Now for sure db driver should be available in your models.
Regarding issue with HMVC I dont think there are any. I'm using HMVC for a while now, and I found no problems in it (working with databases)
I had the same problem and mistake. I missed to extend controllers to MX_Controller. So the solution would be to change CI_Controller to MX_Controller like this:
class Special_cart extends MX_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('productmodel');
$this->load->model('stockmodel');
}
public function index()
{
if ($this->session->userdata('cart'))
{
# get product id's and each quantity
$cart_product_list = array_count_values($this->session->userdata('cart'));
# get list of product_id
$product_list = array_keys($cart_product_list);
# get product details
$cart_products = $this->productmodel->cart_get_products_details($product_list);
$final_cart_array = array();
foreach($cart_products as $cart_product){
$product_stock = $this->stockmodel->view_product_stock($cart_product["id"]);
if(empty($product_stock) || $product_stock["UNITS"]<=0)
$cart_product["UNITS"] = 0;
else{
if($cart_product_list[$cart_product["id_web"]]>$product_stock["UNITS"])
$cart_product["UNITS"] = $product_stock["UNITS"];
else{
$cart_product["UNITS"] = $cart_product_list[$cart_product["id_web"]];
}
}
$final_cart_array[] = $cart_product;
}
$refresh_cart_array = array();
foreach($final_cart_array as $cart_product){
for($i=1;$i<=$cart_product["UNITS"];$i++){
$refresh_cart_array[] = $cart_product["id_web"];
}
}
$this->load->view("special_cart",array(
'refresh_cart_array' => $refresh_cart_array,
'final_cart_array' => $final_cart_array
));
} else {
$this->load->view("special_cart",array(
'refresh_cart_array' => NULL,
'final_cart_array' => NULL
));
}
}
}
this is also explained in the documentation
https://bitbucket.org/wiredesignz/codeigniter-modular-extensions-hmvc/
, here the quote:
Notes:
To use HMVC functionality, such as Modules::run(), controllers must
extend the MX_Controller class. To use Modular Separation only,
without HMVC, controllers will extend the CodeIgniter Controller
class. You must use PHP5 style constructors in your controllers. ie:
<?php
class Xyz extends MX_Controller
{
function __construct()
{
parent::__construct();
}
}
I'm using PHP 5.3's class_alias to help process my Symfony 1.4 (Doctrine) forms. I use a single action to process multiple form pages but using a switch statement to choose a Form Class to use.
public function executeEdit(sfWebRequest $request) {
switch($request->getParameter('page')) {
case 'page-1':
class_alias('MyFormPage1Form', 'FormAlias');
break;
...
}
$this->form = new FormAlias($obj);
}
This works brilliantly when browsing the website, but fails my functional tests, because when a page is loaded more than once, like so:
$browser->info('1 - Edit Form Page 1')->
get('/myforms/edit')->
with('response')->begin()->
isStatusCode(200)->
end()->
get('/myforms/edit')->
with('response')->begin()->
isStatusCode(200)->
end();
I get a 500 response to the second request, with the following error:
last request threw an uncaught exception RuntimeException: PHP sent a warning error at /.../apps/frontend/modules/.../actions/actions.class.php line 225 (Cannot redeclare class FormAlias)
This makes it very hard to test form submissions (which typically post back to themselves).
Presumably this is because Symfony's tester hasn't cleared the throughput in the same way.
Is there a way to 'unalias' or otherwise allow this sort of redeclaration?
As an alternate solution you can assign the name of the class to instantiate to a variable and new that:
public function executeEdit(sfWebRequest $request) {
$formType;
switch($request->getParameter('page')) {
case 'page-1':
$formType = 'MyFormPage1Form';
break;
...
}
$this->form = new $formType();
}
This doesn't use class_alias but keeps the instantiation in a single spot.
I do not know for sure if it is possible, but judging from the Manual, I'd say no. Once the class is aliased, there is no way to reset it or redeclare it with a different name. But then again, why do use the alias at all?
From your code I assume you are doing the aliasing in each additional case block. But if so, you can just as well simply instantiate the form in those blocks, e.g.
public function executeEdit(sfWebRequest $request) {
switch($request->getParameter('page')) {
case 'page-1':
$form = new MyFormPage1Form($obj);
break;
...
}
$this->form = $form;
}
You are hardcoding the class names into the switch/case block anyway when using class_alias. There is no advantage in using it. If you wanted to do it dynamically, you could create an array mapping from 'page' to 'className' and then simply lookup the appropriate class.
public function executeEdit(sfWebRequest $request) {
$mapping = array(
'page-1' => 'MyFormPage1Form',
// more mappings
);
$form = NULL;
$id = $request->getParameter('page');
if(array_key_exists($id, $mapping)) {
$className = $mapping[$id];
$form = new $className($obj);
}
$this->form = $form;
}
This way, you could also put the entire mapping in a config file. Or you could create FormFactory.
public function executeEdit(sfWebRequest $request) {
$this->form = FormFactory::create($request->getParameter('page'), $obj);
}
If you are using the Symfony Components DI Container, you could also get rid of the hard coded factory dependency and just use the service container to get the form. That would be the cleanest approach IMO. Basically, using class_alias just feels inappropriate here to me.
function class_alias_once($class, $alias) {
if (!class_exists($alias)) {
class_alias($class, $alias);
}
}
This doesn't solve the problem itself, but by using this function it is ensured that you don't get the error. Maybe this will suffice for your purpose.
