<p>This plugin makes all custom fields (post meta) visible in the “Custom Fields” meta box on post edit screens.</p>


Show Hidden Post Meta

As a plugin developer, I create hidden post meta all the time and sometimes I need to see it to debug it. This does what it says it does, and well. Its simple and hasn't been updated for a while, but I'm glad it exists!

PS: If you need someone to take this one over, let me know. I'll keep it tested and updated if you're unable to.

Still works on 5.5

<p><strong>Codeideal Open Fields</strong> lets you add custom fields to posts, pages, custom post types, taxonomies, and users. The admin interface is built with React and TypeScript — fast, responsive, and intuitive.</p>
<p>All features are free. No premium tier. No locked functionality.</p>
<h4>Quick Start</h4>
<pre><code>get_field( 'my_field' ) — retrieve any field value.

the_field( 'my_field' ) — echo a field value directly.
</code></pre>
<h4>Template Examples</h4>
<p><strong>Simple field:</strong></p>
<pre><code><?php echo esc_html( get_field( 'subtitle' ) ); ?>
</code></pre>
<p><strong>Repeater loop:</strong></p>
<pre><code><?php while ( have_rows( 'team_members' ) ) : the_row(); ?>
    <h3><?php the_sub_field( 'name' ); ?></h3>
    <p><?php the_sub_field( 'role' ); ?></p>
<?php endwhile; ?>
</code></pre>
<p><strong>User field (with prefix):</strong></p>
<pre><code><?php echo esc_html( get_field( 'company', 'user_' . $user_id ) ); ?>
</code></pre>

<h4>ACF-Compatible API</h4>
<p>If you know ACF, you already know Open Fields. The template API uses the same function names:</p>
<ul>
<li><code>get_field()</code> / <code>the_field()</code></li>
<li><code>get_fields()</code> / <code>update_field()</code> / <code>delete_field()</code></li>
<li><code>have_rows()</code> / <code>the_row()</code> / <code>get_sub_field()</code> / <code>the_sub_field()</code></li>
<li><code>get_row()</code> / <code>get_rows()</code> / <code>reset_rows()</code> / <code>get_row_index()</code></li>
<li><code>get_field_object()</code> / <code>get_sub_field_object()</code></li>
</ul>
<p>When ACF is also active, these wrappers are not loaded — no conflicts. Both plugins store data as standard WordPress meta, so they can coexist.</p>
<p>Every function also has a prefixed version (e.g. <code>cofld_get_field()</code>) that is always available regardless of other plugins.</p>
<h4>Field Types</h4>
<ul>
<li><strong>Basic:</strong> Text, Textarea, Number, Email, URL, Password</li>
<li><strong>Choice:</strong> Select, Checkbox, Radio, Switch</li>
<li><strong>Date & Time:</strong> Date, Time, DateTime, Color Picker</li>
<li><strong>Media:</strong> Image, File, Gallery</li>
<li><strong>Content:</strong> WYSIWYG Editor, Link</li>
<li><strong>Relational:</strong> Post Object, Taxonomy, User</li>
<li><strong>Layout:</strong> Repeater, Group</li>
</ul>
<h4>Location Rules</h4>
<p>Assign field groups to:</p>
<ul>
<li>Post types (including custom post types)</li>
<li>Page templates</li>
<li>Post status / format / category</li>
<li>Taxonomy terms</li>
<li>User roles</li>
</ul>
<h4>Source Code</h4>
<p>The admin JS and CSS are compiled from TypeScript/React source. All other files are uncompressed.</p>
<ul>
<li><strong>Source repo:</strong> <a href="https://github.com/novincode/openfields" rel="nofollow ugc">github.com/novincode/openfields</a></li>
<li><strong>Admin source:</strong> <a href="https://github.com/novincode/openfields/tree/main/admin/src" rel="nofollow ugc">admin/src/</a></li>
<li><strong>Build:</strong> <code>pnpm install && pnpm build</code> (Vite + TypeScript)</li>
</ul>
