Rezerla

<p><strong>Rezerla Post List Field Search</strong> adds a <strong>Search in</strong> dropdown next to the search box on post list screens (<code>edit.php</code>). Search by title, content, slug, custom fields, post meta, or taxonomy — individually or across all configured fields at once.</p>
<ul>
<li>Admin-only — no impact on front-end search</li>
<li>Per post type configuration</li>
<li>Core fields, post meta, and taxonomies</li>
<li>Optional list table columns (Show in table checkbox)</li>
<li>Temporary column and highlight when searching by a single field</li>
<li>Field discovery for meta keys and taxonomies</li>
<li>Lightweight — no frameworks or subscriptions</li>
<li>Default configuration for WP Store Locator (<code>wpsl_stores</code>)</li>
<li>No data collection or external API calls</li>
<li>Translations: English (default), Polish, German, French, Spanish, Italian</li>
</ul>
<h3>Usage example</h3>
<p>On a WP Store Locator store list (<code>edit.php?post_type=wpsl_stores</code>):</p>
<ol>
<li>Enter “Katowice” in the search box.</li>
<li>Select <strong>City</strong> in the dropdown.</li>
<li>Click the search button.</li>
</ol>
<p>URL: <code>edit.php?post_type=wpsl_stores&s=Katowice&rezerla_plfs_field=city</code></p>
<h3>List table columns</h3>
<p>Check <strong>Show in table</strong> in field settings to display meta or taxonomy values on the list.<br />
When searching by a single field, that column appears temporarily and is highlighted even without the checkbox.</p>
