Usage

Component creation

In order to use this extension, first thing you need to do is to create a blog (you can change the name if you want) component and configure it. Here is the example of minimal configuration (in your config/main.php):

    'components' => [
        ...
        'blog' => [
            'class' => '\monitorbacklinks\yii2wp\Wordpress',
            'endpoint' => 'http://example.com/xmlrpc.php',
            'username' => 'demo',
            'password' => 'demo'
        ]
        ...
    ]

First API request

When component is configured, you can start making requests to your Wordpress site.

For example, get ten latest published posts. Select guid, post_title and post_content fields only:

    $blogPosts = Yii::$app->blog->getPosts([
        'post_status' => 'publish',
        'number' => 10
    ], ['guid', 'post_title', 'post_content']);

Or create a new post with title "New post" and content "Hello world!":

    $postID = Yii::$app->blog->newPost('New post', 'Hello world!');

Caching request results

Making API calls to an external application means delays. If you don't want your users to wait for a Wordpress response each time, caching is a right thing to do:

    // The user profile will be fetched from cache if available.
    // If not, the query will be made against XML-RPC API and cached for use next time.
    $profile = Yii::$app->blog->cache(function (Wordpress $blog) {
        return $blog->getProfile();
    });

In case, if you need something more complex, you can disable caching for some requests:

    $blogPosts = Yii::$app->blog->cache(function (Wordpress $blog) {

        // ... queries that use query cache ...

        return $blog->noCache(function (Wordpress $blog) {
            // this query will not use query cache
            return $blog->getPosts();
        });
    });

Caching will work for data retrieval queries only. Queries that create, update or delete records will not use caching component.

Configuration parameters

$endpoint

string Wordpress XML-RPC API endpoint URL.

$username

string Wordpress authentication username.

Please note, that any actions made by XML-RPC will be made on behalf of this user.

$password

This configuration array should follow the following format:

Empty array means that no proxy should be used.

Default value: [].

$authConfig

This configuration array should follow the following format:

Empty array means that no HTTP authentication should be used.

Default value: [].

$catchExceptions

boolean Whether to catch exceptions thrown by Wordpress API, pass them to the log and return default value, or transmit them further along the call chain.

Default value: true.

$enableQueryCache

boolean Whether to enable query caching.

Default value: true.

$queryCacheDuration

List of available methods

The full list of available methods can be found in Wordpress XML-RPC PHP Client Class Reference.

Please note, that all those methods are throwing an exceptions in case of any errors. While this extension is configured (by default), in case of errors, to return an empty array for any data retrial methods and false for any create, update or delete methods. Please see $catchExceptions configuration option for details.

Errors logging

There are a lot of things that can go wrong (network problems, wrong Wordpress user permissions, etc.). If $catchExceptions configuration option is set to true (default value), this extension will catch them and pass to monitorbacklinks\yii2wp\Wordpress::* logging category.

In order to see them, you can configure your Yii2 log component to something similar to this:

    'components' => [
        ...
        'log' => [
            'targets' => [
                'file' => [
                    'class' => 'yii\log\FileTarget',
                    'levels' => ['error'],
                    'categories' => ['monitorbacklinks\yii2wp\Wordpress::*'],
                ],
            ],
        ],
        ...
    ]
