<p>This plugin filters the response content of requests made to the WordPress <a href="https://wordpress.org/extend/plugins/json-api" rel="ugc">JSON-API</a> to include data for translations created through the <a href="http://wpml.org" rel="nofollow ugc">WPML Multilingual CMS</a> plugin. One may also request the translation of response objects to a supported target language.</p>
<p><a href="http://www.lettersandlight.org" rel="nofollow ugc">The Office of Letters and Light</a> uses this plugin to integrate WordPress and <a href="http://wpml.org" rel="nofollow ugc">WPML</a> with its Rails-built <a href="http://www.nanowrimo.org" rel="nofollow ugc">National Novel Writing Month</a> event-site application. We use WordPress to manage all back-end site content and our <a href="http://github.com/lettersandlight/kiosk" rel="nofollow ugc">Kiosk Ruby gem</a> for consuming, caching, searching, and serving the content through Rails. This could not have been so easily accomplished without the well-built and extensible <a href="https://wordpress.org/extend/plugins/json-api" rel="ugc">JSON-API</a> for which we are grateful. And without the <a href="http://wpml.org" rel="nofollow ugc">WPML</a> plugin, we would not have such an intuitive and capable CMS i18n interface.</p>
<h3>Usage</h3>

<h3>1. Augmented response objects</h3>
<h3>1.1. Language</h3>
<p>After enabling the WPML JSON-API plugin, response objects will contain the<br />
language in which the object content was written.</p>
<p>Let’s take a look at an example response to a request made to <code>http://wordpress.site.example/api/get_page/?dev=1&id=127</code>.</p>
<pre><code>{
  "status": "ok",
  "page": {
    "id": 127,
    "type": "page",
    "slug": "the-best-page",
    "url": "http:\/\/wordpress.site.example\/the-best-page\/",
    "status": "publish",
    "title": "The Best Page",
    "title_plain": "The Best Page",
    "content": "<p>This is the best page ever created.<\/p>\n<blockquote><p>Best damn page ever. – Dan<\/p><\/blockquote>\n",
    "excerpt": "This is the best page ever created. Best damn page ever. – Dan",
    "date": "2011-09-22 18:48:09",
    "modified": "2011-09-22 18:54:55",
    "categories": [],
    "tags": [],
    "author": {
      "id": 4,
      "slug": "dzachary",
      "name": "Daniel Duvall",
      "first_name": "Daniel",
      "last_name": "Duvall",
      "nickname": "Daniel Duvall",
      "url": "",
      "description": ""
    },
    "comments": [],
    "attachments": [],
    "comment_count": 0,
    "comment_status": "open",
    "translations": {
      "en": {
        "post_title": "The Best Page",
        "post_status": "publish",
        "id": 21,
        "language_code": "en",
        "is_original": true,
        "resource_id": 127
      },
      "es": {
        "post_title": "La P\u00e1gina Mejor",
        "post_status": "publish",
        "id": 22,
        "language_code": "es",
        "is_original": false,
        "resource_id": 131
      }
    },
    "language": "en"
  }
}
</code></pre>
<p>The <code>language</code> property specifies the code of the language in which the page<br />
was written—pretty simple.</p>
<h3>1.2. Translations</h3>
<p>The <code>translations</code> objects of the same example response given in Section 1.1.<br />
include data for each <em>published</em> resource that comprises a translation of<br />
its parent object.</p>
<pre><code>"translations": {
  "en": {
    "post_title": "The Best Page",
    "post_status": "publish",
    "id": 21,
    "language_code": "en",
    "is_original": true,
    "resource_id": 127
  },
  "es": {
    "post_title": "La P\u00e1gina Mejor",
    "post_status": "publish",
    "id": 22,
    "language_code": "es",
    "is_original": false,
    "resource_id": 131
  }
</code></pre>
<p>Properties included in each member of the <code>translations</code> object depend on the<br />
type of parent object.</p>
<p>All <code>post</code> and <code>page</code> objects will include the following.</p>
<ul>
<li><code>id</code> – The ID of the translation object.</li>
<li><code>language_code</code> – The code of the language in which the translation is written. Each translation object is also keyed by this value.</li>
<li><code>is_original</code> – Specifies whether the language of this translation is the language in which the original work was written.</li>
<li><code>resource_id</code> – The ID of the translated version of the parent object.</li>
<li><code>post_title</code> – The title of the translated post/page.</li>
<li><code>post_status</code> – The status of the translated post/page. Always ‘publish’.</li>
<li><code>post_id</code> – Redundancy of <code>resource_id</code>.</li>
</ul>
<p>All <code>category</code> objects will include the following.</p>
<ul>
<li><code>id</code> – The ID of the translation object.</li>
<li><code>language_code</code> – The code of the language to which the category was translated.</li>
<li><code>is_original</code> – Specifies whether the language of this translation is the language of the original category.</li>
<li><code>resource_id</code> – The ID of the translated version of the parent object.</li>
<li><code>name</code> – The translated category name.</li>
<li><code>term_id</code> – Redundancy of <code>resource_id</code>.</li>
<li><code>post_count</code> – The number of posts tagged with the translated category.</li>
</ul>
<h3>2. Filtering response objects by language</h3>
<p>You may tell the API to only return objects for a specific language by using<br />
the <code>language</code> parameter.</p>
<h3>2.1. Specifying the language</h3>
<p>The <code>language</code> parameter should be one of the supported language codes.</p>
<p>Example:</p>
<ul>
<li><code>http://wordpress.site.example/api/get_category_index/?language=es&dev=1</code></li>
</ul>
<h3>2.2. Filtered results</h3>
<p>Following is a example response to the example request in Section 2.1.</p>
<pre><code>{
  "status": "ok",
  "count": 2,
  "categories": [
    {
      "id": 13,
      "slug": "noticias-de-ultima-hora-2",
      "title": "Noticias de \u00daltima Hora",
      "description": "",
      "parent": 0,
      "post_count": 1,
      "translations": {
        "en": {
          "name": "Breaking News",
          "term_id": 4,
          "post_count": 2,
          "id": 9,
          "language_code": "en",
          "is_original": true,
          "resource_id": 4
        },
        "es": {
          "name": "Noticias de \u00daltima Hora",
          "term_id": 13,
          "post_count": 1,
          "id": 26,
          "language_code": "es",
          "is_original": false,
          "resource_id": 13
        }
      },
      "language": "es"
    }
  ]
}<h3>3. Response object translation</h3>
</code></pre>
<p>You can request objects to be translated before they are returned. This may<br />
save you some requests if you have the slug or ID and just need the object in<br />
a specific language.</p>
<h3>3.1. Specifying the target language</h3>
<p>The target language can be specified by passing a <code>to_language</code> parameter. The<br />
value should be one of the supported language codes.</p>
<p>Example:</p>
<ul>
<li><code>http://wordpress.site.example/api/get_page/?slug=the-best-page&to_language=es&dev=1</code></li>
</ul>
<h3>3.2. Translated results</h3>
<p>Following is an example response to the example request in Section 3.1.</p>
<pre><code>{
  "status": "ok",
  "page": {
    "id": 127,
    "type": "page",
    "slug": "la-pagina-mejor",
    "url": "http:\/\/wordpress.site.example\/the-best-page\/",

        "post_id": 127,
        "post_title": "The Best Page",
        "post_status": "publish",
        "id": 21,
        "language_code": "en",
        "is_original": true,
        "resource_id": 127
      },
      "es": {

    "original_slug": "the-best-page",
    "original_title": "The Best Page",

  }
}
</code></pre>
<p>As you can see the <code>slug</code>, <code>title</code>, <code>title_plain</code>, <code>excerpt</code>, and <code>content</code><br />
properties have been rewritten with the Spanish translation. In addition, the<br />
original properties have been prefixed with <code>original_</code>. This is always the<br />
case for all properties except for <code>excerpt</code> and <code>content</code>. In an effort to<br />
save on response size, the latter have been omitted.</p>
<h3>3.3. Translatable objects and properties</h3>
<p>Here are all of the translatable object types and their translatable<br />
properties, those that can be rewritten as described in Section 3.2.</p>
<p>Objects <code>post</code> and <code>page</code>:</p>
<ul>
<li><code>slug</code></li>
<li><code>title</code></li>
<li><code>title_plain</code></li>
<li><code>excerpt</code></li>
<li><code>content</code></li>
</ul>
<p>Objects <code>tag</code> and <code>category</code>:</p>
<ul>
<li><code>slug</code></li>
<li><code>title</code></li>
<li><code>description</code></li>
</ul>


WPML JSON API

An extension to JSON-API for sites using the WPML Multilingual CMS plugin.

Nikolay Bachiyski

<p>Sometimes we want the front end of our blog to be translated for the users, but keep the backend admin panel in English. Admin in English does just that.</p>


Admin in English

Admin in English lets you have your administration panel in English, even if the rest of your blog is translated into another language.
