<p>This ACF plugin makes it possible to store ACF data in structured database tables instead of WordPress core meta tables.</p>
<p>It uses ACF’s <code>acf/update_field_group</code> hook to create/update the database and then uses <code>acf/save_post</code> hook to store the data.</p>
<p>It was heavily inspired by Austin Ginder’s post <a href="https://anchor.host/acf-custom-fields-stored-in-custom-table/" rel="nofollow ugc">https://anchor.host/acf-custom-fields-stored-in-custom-table/</a>.</p>

<h4>Relational Fields</h4>
<p>This plugin supports the following relational field types: Post Object, Page Link, Relationship, Taxonomy and User.</p>
<p>It can store both single and multiple values based on the <code>multiple</code> option.</p>
<ul>
<li>If it’s a single value field, then the column type will be <code>bigint(20) unsigned</code></li>
<li>If it’s a multiple value field, then the column type will be longtext and the date will be stored in json format.</li>
</ul>
<p>You can query relational fields with multiple values using using MySQL’s function <a href="https://dev.mysql.com/doc/refman/5.7/en/json-search-functions.html#function_json-contains" rel="nofollow ugc">JSON_CONTAINS</a>.<br />
Here is an example:</p>
<p>Table:</p>
<pre><code>+---------+-------------------+--------+
| post_id |       title       | stores |
+---------+-------------------+--------+
|       1 | Lord of the Flies | [1,2]  |
|       2 | The Island        | [2]    |
|       3 | 1984              | [3]    |
+---------+-------------------+--------+
</code></pre>
<p>Query:</p>
<pre><code>SELECT * FROM wp_acf_books WHERE JSON_CONTAINS(stores, 2, '$')
</code></pre>
<p>The query above will return “Lord of the Flies” and “The Island”.</p>
<h4>ACF Compatibility</h4>
<p>This plugin was tested with <em>ACF 5 FREE Version</em> .</p>
