Requirements

The latest PHP and Composer versions to use the Akismet library.

If you plan to play with the sources, you will also need the latest Robo and Material for MkDocs versions.

Installing via Composer

From a command prompt, run:

composer require cedx/yii2-akismet

Usage

In your application configuration file, you can use the following component:

<?php return [
  'components' => [
    'akismet' => [
      'class' => 'yii\akismet\http\Client',
      'apiKey' => '123YourAPIKey',
      'blog' => [
        'class' => 'yii\akismet\Blog',
        'url' => 'http://www.yourblog.com'
      ]
    ]
  ]
];

Once the yii\akismet\http\Client component initialized with your credentials, you can use its methods.

Key verification

<?php
use yii\akismet\http\{ClientException};

try {
  $client = \Yii::$app->akismet;
  $isValid = $client->verifyKey();
  echo $isValid ? 'The API key is valid' : 'The API key is invalid';
}

catch (ClientException $e) {
  echo 'An error occurred: ', $e->getMessage();
}

Comment check

<?php
use yii\akismet\{Author, Comment};

try {
  $comment = new Comment(
    new Author('127.0.0.1', 'Mozilla/5.0'),
    ['content' => 'A user comment', 'date' => new \DateTime]
  );

  $isSpam = $client->checkComment($comment);
  echo $isSpam ? 'The comment is spam' : 'The comment is ham';
}

catch (ClientException $e) {
  echo 'An error occurred: ', $e->getMessage();
}

Submit spam / ham

<?php
try {
  $client->submitSpam($comment);
  echo 'Spam submitted';

  $client->submitHam($comment);
  echo 'Ham submitted';
}

catch (ClientException $e) {
  echo 'An error occurred: ', $e->getMessage();
}

Events

The yii\akismet\http\Client class triggers some events during its life cycle.

The Client::eventRequest event

Emitted every time a request is made to the remote service:

<?php
use yii\akismet\http\{Client};
use yii\httpclient\{RequestEvent};

$client->on(Client::eventRequest, function(RequestEvent $event) {
  echo 'Client request: ', $event->request->url;
});

The Client::eventResponse event

Emitted every time a response is received from the remote service:

<?php
use yii\akismet\http\{Client};
use yii\httpclient\{RequestEvent};

$client->on(Client::eventResponse, function(RequestEvent $event) {
  echo 'Server response: ', $event->response->statusCode;
});

Unit tests

In order to run the tests, you must set the AKISMET_API_KEY environment variable to the value of your Akismet API key:

export AKISMET_API_KEY="<123YourAPIKey>"

Then, you can run the test script from the command prompt:

composer run-script test
