<p>Due to security/privacy concerns, JSON REST API (WP API) only allows post meta data (custom field value) for authenticated users.<br />
This plugin is an easy way to make post meta available when unauthenticated.</p>
<p>After activate the plugin, go to WP API Customizer option page.<br />
Click the plus icon to add rows.<br />
Set JSON attributes and custom field names in your posts that you want to use when unauthenticated.<br />
The JSON REST API will provide the data as “post_meta” like the following:</p>
<pre><code>"post_meta":{"your_attribute_a":"Custom Field A value","your_attribute_b":"Custom Field B value"}
</code></pre>

<p>This plugin creates a new field for <a href="https://wordpress.org/plugins/advanced-custom-fields/" title="Advanced Custom Fields" rel="ugc">Advanced Custom Fields (ACF)</a><br />
extending the functionality of the built-in Google Map field with several handy features:</p>
<ul>
<li>Saves map center. You can center your maps wherever you want and indicate that you want to save that place as map center. This can be handy, if you want your front-end map to show some specific place in the center of the map (not necessary the location marker).</li>
<li>Saves zoom level.</li>
<li>Disables (optionally) map zooming with a scrollwheel. Sometimes you can get annoyed with your maps starting to zoom, when you scroll the post in the admin area. This feature comes handy here.</li>
<li>Shows location coordinates. It is easy to get any place’s location coordinates (latitude and longitude) with this plugin by setting a marker to the place you need using user friendly map interface.</li>
<li>Compatible with the data format of the Google Map field coming with ACF. See F.A.Q. for details.</li>
<li>Saves all maps shown at a page in the global array. This is a bonus for programmers. See F.A.Q. for details.</li>
</ul>
<p>The plugin makes use of the Google Maps API version 3.<br />
The plugin doesn’t use an API key and is therefore operating under the <a href="https://developers.google.com/maps/faq#usage_pricing" rel="nofollow ugc">restrictions of the free Google Maps API</a>,<br />
which should be more than enough for most websites.</p>
<h4>Compatibility</h4>
<p>This ACF field type is compatible with:</p>
<ul>
<li>ACF 4</li>
<li>ACF 5 (PRO version)</li>
<li>Google Map field coming with ACF 4/5. See F.A.Q.</li>
</ul>
<h4>Translations</h4>
<p>The plugin is translated to:</p>
<ul>
<li>French</li>
<li>German</li>
<li>Netherlands</li>
<li>Russian</li>
<li>Ukrainian</li>
</ul>
<p>There is a POT file under the <code>lang</code> directory holding all translation strings, so it should be pretty easy to translate to other languages.</p>

ACF: Google Map Extended

Fantastic plugin that adds much-needed functionality to the ACF Google Map field. I appreciate that the array of key-value pairs is saved in exactly the same way as the default Google Map field, but with the addition of values for zoom, center_lat, and center_lng:
array(
  'address' => '',
  'lat' => '',
  'lng' => '',
  'zoom' => '',
  'center_lat' => '',
  'center_lng' => '',
)
Ultimately this data allows you to recreate the exact Google Map that the user creates in WP Admin on the front-end of your site - something that simply isn't possible with the default ACF Google Map field. Keep up the great work!



A More Powerful ACF Google Maps Field

ACF field. Saves map center, zoom level. Disables map zooming on scroll. Shows location coordinates. Bonus for programmers.
