I'm just trying a very simple test
<?php
require 'vendor/autoload.php';
class Blog
{
public function post ()
{
return 'ok';
}
}
$builder = new \Aura\Di\ContainerBuilder();
$blog = $builder->newInstance('Blog');
echo $blog->post();
This results to:
Fatal error: Uncaught Error: Call to undefined method Aura\Di\Container::post()
Am I missing something?
Yes , you are missing to read the docs. You have created builder. Next you need to get the di via new instance. This is what you assigned to blog variable.
Please consider reading getting started http://auraphp.com/packages/3.x/Di/getting-started.html#1-1-1-2
// autoload and rest of code
$builder = new \Aura\Di\ContainerBuilder();
$di = $builder->newInstance();
Now you create instance of object
$blog = $di->newInstance('Blog');
echo $blog->post();
Please read the docs.

So, I'm trying to set up php-di for the first time, but I'm having some trouble with the builder. I keep getting the error:
Uncaught exception 'DI\NotFoundException' with message 'No entry or class found for 'IConnection'' in /path/PHPDiContainer.php'
Where am I going wrong in my container setup?
<?php
require_once 'vendor/autoload.php';
use repositories\Connection;
use irepositories\IConnection;
use DI\ContainerBuilder;
$container = DI\ContainerBuilder::buildDevContainer();
$builder = new DI\containerBuilder();
$builder->addDefinitions([
IConnection::class => DI\object(Connection::class)
]);
$container = $builder->build();
$connection = $container->get('Connection');
... Code to show it works.
?>
IConnection::class returns the fully qualified class name: irepositories\IConnection. So you are registering the connection under that name in PHP-DI.
If you want to get it, Connection will not match anything. You need to do:
$connection = $container->get('irepositories\IConnection');
// or
$connection = $container->get(IConnection::class);
I want to give a 3rd party PHP application access to Yii2 user data (HumHub) and have tried this:
function getUserId() {
require_once('../protected/vendor/yiisoft/yii2/Yii.php');
$yiiConfig = require('../protected/config/common.php');
(new humhub\components\Application($yiiConfig));
$user = Yii::$app->user->identity;
return $user;
}
This does not work. There are no errors up until new humhub\components\Application($yiiConfig) but then the 3rd party app breaks with no error thrown and the function does not return anything.
I did find this solution which does not work.
Is there are reason this does not work or is there an alternate solution to getting Yii2 user data properly?
This is how to do it in HumHub V1.0
require_once('../protected/vendor/yiisoft/yii2/Yii.php');
$config = yii\helpers\ArrayHelper::merge(
require('../protected/humhub/config/common.php'),
require('../protected/humhub/config/web.php'),
(is_readable('../protected/config/dynamic.php')) ? require('../protected/config/dynamic.php') : [],
require('../protected/config/common.php'),
require('../protected/config/web.php')
);
new yii\web\Application($config); // No 'run()' invocation!
Now I can get $user object:
$user = Yii::$app->user->identity;
Indeed an error should be thrown, but, the error settings of your PHP may be overridden or set to not display errors.
You call undefined object Yii::$app->user->identity. The reason, from documentation because you have not initialized the Yii object. So your code should be as follows:
function getUserId() {
require_once('../protected/vendor/yiisoft/yii2/Yii.php');
$yiiConfig = require('../protected/config/common.php');
(new humhub\components\Application($yiiConfig)); // try to comment this line too if it does not work
// Add The Following Line
new yii\web\Application($yiiConfig); // Do NOT call run() here
$user = Yii::$app->user->identity;
return $user;
}
I found a problem that I not sure if is a bug of the php or on my code (probably mine) so let me show you what is happening:
<?php namespace MyApp\Conciliation;
use SimpleExcel\SimpleExcel;
use ForceUTF8\Encoding;
use MyApp\Conciliation\Gol;
class Conciliation {
protected function equalizeFile($file, $providerName)
{
$type = false;
$nfile = 'public'.$file;
// TEST 1: the ideal aproach. not working (see error#1 bellow)
$provider = new $providerName();
// TEST 2: working, getting the correct response
$provider = new Gol();
// TEST 3: working, getting the correct response
$provider = new MyApp\Conciliation\Gol();
$provider->equalize($nfile);
}
Note, the $providerName = 'Gol';
error1
Class 'Gol' not found
http://inft.ly/N8Q6F4B
So, there is any way that I could keeping using variables to instantiate aliases similar as above?
Edit, Problem solved: working example
<?php namespace MyApp\Conciliation;
use SimpleExcel\SimpleExcel;
use ForceUTF8\Encoding;
class Conciliation {
protected function equalizeFile($file, $providerName)
{
$type = false;
$nfile = 'public'.$file;
$providerName = "MyApp\\Conciliation\\".$providerName;
$provider = new $providerName();
$provider->equalize($nfile);
}
http://php.net/manual/en/language.namespaces.dynamic.php
If you are calling the class dynamically, you have to use the full path to the class.
So, your call to equalizeFile should be something like:
equalizeFile("myFile", "MyApp\\Conciliation\\Gol");
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'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.
