Advanced Custom Fields: Widget

A widget that is able to use content from an ACF field group

John Huebner

<p><strong><em>This is an add on plugin for Advanced Custom Fields (ACF) >= Version 5.</em></strong></p>
<p><strong><em>This plugin will not work with ACF Version 4.</em></strong></p>
<p>This plugin will not provide any functionality if ACF >=5 is not installed.***</p>
<p>This plugin does not create a new type of field or any admin interface. This plugin when used as<br />
explained below makes the existing ACF Relationship and Post Object fields work bi-directionaly,<br />
automatically updating the relationship field on the other end of the relationship.</p>
<p>For more information see <a href="https://wordpress.org/plugins/post-2-post-for-acf/" rel="ugc">Other Notes</a></p>
<h3>Github Repository</h3>
<p>This plugin is also on GitHub<br />
<a href="https://github.com/Hube2/acf-post2post" rel="nofollow ugc">https://github.com/Hube2/acf-post2post</a></p>
<h3>How To Use</h3>
<ul>
<li>Create a relationship or post object field.</li>
<li>The field must be at the top level. It cannot be a subfield of a repeater or a flexible content field.</li>
<li>The field name must be the same on all posts. In other words if you want to have different post types be related then you must add a field with the same field name on both post types.</li>
</ul>
<p>When you add a post to a relationship or post object field and the same field name appears on the post added to the relationship then the relationship field on the related post will be updated to include a relationship to the post being edited.</p>
<p>If a post is removed from a relationship then the post being removed will also be updated to remove the relationship to the post being edited.</p>
<h3>Post Object Fields</h3>
<p>If a post object field is being used</p>
<ul>
<li>If it allows multiple values then it will work the same way that relationship fields work.</li>
<li>If it does not allow multiple values and the related post already contains a value see Overwrite Settings</li>
</ul>
<h3>Overwrite Settings</h3>
<p>If the field in a related post, whether it is a post object field that only allows 1 value or a relationship field that has a maximum number of related posts, if the field in the related post already has the maximum number of values allowed, by default, a new value will not be added. You can override this default by specifying overwrite settings.</p>
<p>How to add overwrite settings</p>
<pre><code>add_filter('acf-post2post/overwrite-settings', 'my_overwrite_settings');
function my_overwrite_settings($settings) {
  $settings['field_name'] = array(
      'overwrite' => true,
        'type' => 'first'
  );
  return $settings;
}
</code></pre>
<p>Each element of the $settings array is an array. The index of the array is the field that you want to specify settings for. Each field can have 2 arguments.</p>
<ul>
<li>overwrite: true/false or 1/0. If set to true or 1 then new values will overwrite older values. The default value of this setting is false.</li>
<li>type: ‘first’ or ‘last’. Which of the existing values should be removed, the first one added or the last. The default value is ‘first’.</li>
</ul>
<p>after a value is removed from the existing list the new value is added to the end of the list.</p>
<h3>Field Exeptions</h3>
<p>You can disable automatic bidirectional relationships for specific field keys using the filter</p>
<pre><code>// field_XXXXXXXX = the field key of the field
// you want to disable bidirectional relationships for
add_filter('acf/post2post/update_relationships/key=field_XXXXXXXX', '__return_false');
</code></pre>
<h3>After update hooks</h3>
<p>There are two actions that can be used after a post is updated and passes a single post ID. Please make sure you see the subtle difference in these two hooks.</p>
<p>The first is run after each related post is updated</p>
<pre><code>add_action('acf/post2post/relationship_updated', 'my_post_updated_action');
function my_post_updated_action($post_id) {
  // $post_id == the post ID that was updated
  // do something after the related post is updated
}
</code></pre>
<p>The second is run after all posts are updated and passes an array of post IDs.</p>
<pre><code>add_action('acf/post2post/relationships_updated', 'my_post_updated_action');
function my_post_updated_action($posts) {
  // $posts == and array of post IDs that were updated
    // do something to all posts after update
    foreach ($posts as $post_id) {
      // do something to post
    }
}
</code></pre>


ACF Post-2-Post

This plugin saves me a lot of time to manually code each relationship for each project that needs it. Works like a charm.

Save me lots of time.


works perfectly, I checked 6.2.2 wordpress version. 8.1.9 php version.


Works perfectly.
