I am trying to use the Google contacts api from within Yii2.
Google provides a composer interface, so I added
"google/apiclient": "1.0.*#beta"
to my composer.json and did "composer update"
Now - how do I actually use this from within my Yii2 controller?
I have a working, standalone test script that works. In that, it does
require_once 'GoogleClientApi/autoload.php';
$client = new Google_Client();
However, this does not seem to work from Yii.
I've tried adding the require to my index.php file, as follows (copying autoload.php from a previous installation since autoload doesn't seem to come with the composer version - why would this be omitted?)
require(__DIR__ . '/../vendor/google/apiclient/autoload.php');
but this results in the following error when called in my controller:
Call to undefined function app\controllers\Google_Client()
I've read the post on http://www.yiiframework.com/doc-2.0/guide-tutorial-yii-integration.html but this doesn't make much sense to me.
Any help appreciated. Thanks
Your code is almost correct:
require_once 'GoogleClientApi/autoload.php';
$client = new \Google_Client();
The "\" is needed to indicate the class exists in the global namespace, as you are - in that piece of code - under the app\controllers namespace.

I have studied these 2 sources, but none of those works for me.

Yii2 - How do I AutoLoad a custom class?
I have created custom helper class which I want to include in every model, controller and view in my application. I am using Yii2 advanced app version 2.0.11, IDE I am using is PHPStorm
QUESTION:
What I want to achieve is to not use use keyword at the beggining of every class but still be able to simply call AppHelper::myMethod() in models, controllers and views.
How is that possible?
Closest I got it working was using this solution https://stackoverflow.com/a/35160997/5395463
All other solutions did not work for me. I am getting errors like:
PHP Fatal Error – yii\base\ErrorException
Class 'frontend\controllers\AppHelper' not found
when I simply dont include use commons\commands\AppHelper;
or when not using namespace as they suggest there with other settings:
Fatal error: Uncaught exception 'yii\base\UnknownClassException'
with message 'Unable to find 'common\commands\AppHelper'
in file: C:\xampp\htdocs\domain.com\web\common/commands/AppHelper.php.
Namespace missing?' in ...
SOLUTION:
Thanks for your responses, I got it working finaly. https://stackoverflow.com/a/42330631/5395463 solution works best for me.
So I removed namespace from that class, but left it in common\commands folder, added require to frontend/web/index.php and backend/web/index.php files (not sure if I should add it to yii file in root too, I didnt, so far it is working good anyways), and changed calls of class from AppHelper::myMethod() to \AppHelper::myMethod() looks like eveything is working now.
In Yii2 You can use an explicit way adding \ to full namespaced name
\frontend\controllers\AppHelper
so you can sue your method
\frontend\controllers\AppHelper::yourMethod();
Solution for not lazy coders:
create component with your class so you can use it like \Yii::$app->my_component
if even this is too much and your IDE is better than Windows Notepad prepare macro that will print this for you
Solution for lazy coders:
Save your class in single PHP file without namespace.
Modify you entry script to include this class - i.e. for Basic Project Template it's /web/index.php; add there
require(__DIR__ . '/path/to/MyClass.php');
For Advanced Project Template modify it properly.
Now you can use your class by calling it like \MyClass (yes, \ is required and yes, your IDE probably will modify it anyway to MyClass with use MyClass; added at the beginning.
I am working on on the basic tutorial on using ratchet mentioned here http://socketo.me/docs/push.
I have created a test setup for the tutorial that works flawlessly. However, when I am trying to integrate the setup with CakePHP 3 I am running into problems. The ratchet and ZMQ servers are independent just the way mentioned in the tutorial. Only the following piece of code needs to move into CakePHP 3 controllers:
$context = new ZMQContext();
$socket = $context->getSocket(ZMQ::SOCKET_PUSH, 'my pusher');
$socket->connect("tcp://localhost:5555");
$socket->send(json_encode($entryData));
This code basically submits new data to ZMQ queue for forwarding to ratchet. If I place the same 4 lines in a plain PHP file outside CakePHP 3 codebase it works. When I place the same four lines inside APP\Controller\SamplesController it says the class APP\Controller\ZMQContext not found.
CakePHP 3 docs mention that vendor libraries installed via composer will be automatically available through autoloader. I have installed React\ZMQ library via following command:
php composer require react/zmq
I have tried accessing the class via following namespaces but none of them have worked:
ZMQContext ( Class 'App\Controller\ZMQContext' not found )
\ZMQContext ( Class 'App\Controller\ZMQ' not found )
React\ZMQ\ZMQContext ( Class 'App\Controller\React\ZMQ\ZMQContext' not found )
\React\ZMQ\ZMQContext ( Class 'React\ZMQ\ZMQContext' not found )
Probably missing out on some namespace concept in PHP but my understanding is that if ZMQContext is available in a normal PHP file through global namespace, then it should also be available within CakePHP 3 via \ZMQContext.
I have following questions:
How can I push data to ZMQ Queue within my CakePHP 3 APP ?
APP::path() & APP::classname() seems to work only for classes within the CakePHP 3 application. How to check path for a particular vendor library class ?
How to autoload vendor library classes correctly ? (I do not wish to require/require_once them as it will needed to be done for each controller that wants to publish data via ratchet)
Is the assumption about accessing global namespace via \CLASSNAME wrong ?
My second attempt at accessing vendor library class at \ZMQContext resolved to App\Controller\ZMQ. How is that possible when it should have attempted within root namespace ?
ZMQContext is not part of react/zmq library so does it mean it part of default php bindings for libzmq ?
This was a simple typo problem:
$context = new \ZMQContext();
$socket = $context->getSocket(\ZMQ::SOCKET_PUSH, 'my pusher');
$socket->connect("tcp://localhost:5555");
$socket->send(json_encode($entryData));
The second namespace specification in second line was missing.
I have made a new PHP file at the root directory of Magento (next to index.php) and it contains this code:
require 'app/bootstrap.php';
require 'app/Mage.php';
Mage::getModel('core/design_package')->cleanMergedJsCss();
Produces this error:
Fatal error: Call to a member function getModelInstance() on a non-object
in /home/edpadev/public_html/stage/bsr/app/Mage.php on line 463
From my understanding, Magento should dig up that particular method in /app/code/core/Mage/Core/Model/Design/Package.php.
I cannot var_dump it since it cannot instantiate it, I just get the same error when trying to do that.
I am able to call our third-party cache module's observer model and use its methods, and use the simple Mage::app()->cleanCache();, but the core function above does not work, though that is how it appears in examples by other developers in Google search results.
Try this. You might need to setup the store
umask(0);
require 'app/Mage.php';
Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);
I am trying to manage my code in a sample code to learn. I have a sample application whose dir structure is as follow
-Sample
--bootstrap
--app
--class1.php
--class2.php
--class3.php
--config
--public
--resource
--readme
Everything works fine for me, able to autoload the classes and consume all the feature.
Now, I added namespace to my class definition.
namespace Sample\classes;
and my application won't work. In app needs I am trying to add
$obj = new Sample/classes/class1() //no class found
use Sample/classes as Sample
but still class not found error
Any help to consume namespace in this setup will be appreciated.
You need use backslash instead of slash
$obj = new Sample\classes\class1()
To compliment an existing smorgasbord of arrangements between phpunit,autoload and namespace is this:
I have created a simple test project that runs PhpUnit tests and uses namespace autoloading. I register the autoloading in the bootstrap file like so:
set_include_path(get_include_path() . PATH_SEPARATOR . "/path/to/classes/folder");
spl_autoload_register();
and inside a unit test I load and test my class like so:
$obj = new \some\space\someClass(); // which is in the classes/some/space folder
$this->assertTrue($obj->foo()=='bar');
And I get an error
Fatal error: Class '\some\space\someClass' not found in testSomeClass.php...
While this is not phpunit specific you need to change:
spl_autoload_register();
to
spl_autoload_register('spl_autoload');
Any other component that registers an autoloader unregisters the default __autoload().
If your code has an existing __autoload function then this function must be explicitly registered on the __autoload stack. This is because spl_autoload_register() will effectively replace the engine cache for the __autoload function by either spl_autoload() or spl_autoload_call().
So this is how spl-autoload works together with anything else that uses autoloading.
Make sure your path to classes folder is made relative to script which is run for tests execution. If the script is in subfolder of your projects (for example tests/) then your path should be ../path/to/classes/folder
That's what I have in my tests/bootstrap.php
set_include_path(dirname(__FILE__).'/../classes'.PATH_SEPARATOR.get_include_path());
spl_autoload_extensions('.php');
spl_autoload_register('spl_autoload');
