<p>The Query Loop block in WordPress does not include a “Random” ordering option in the sidebar UI.<br />
However, WordPress core <em>does</em> support <code>orderby = rand</code> in <code>WP_Query</code>.</p>
<p>The problem:<br />
Using <code>"orderBy": "rand"</code> inside a Query Loop block can cause the <strong>Site Editor preview to fail</strong>, because <code>rand</code> is not included in the REST API schema for posts.</p>
<p>This plugin fixes that by extending the REST API orderby enum so the editor recognizes <code>"rand"</code> as valid.</p>
<h3>✔ What this plugin does</h3>
<ul>
<li>Adds <code>"rand"</code> to the REST API <code>orderby</code> enum for posts and pages.  </li>
<li>Allows the Query Loop block to use <code>"orderBy": "rand"</code> safely.  </li>
<li>Prevents JSON errors and broken previews in the Site Editor.  </li>
<li>Makes “random post” layouts work reliably both in the editor and frontend.</li>
</ul>
<h3>⚠ What this plugin does <em>not</em> do</h3>
<ul>
<li>It does <strong>not</strong> add a “Random” option to the Query Loop UI dropdown.<br />
(That UI is defined in Gutenberg’s JavaScript.)</li>
<li>You must still set <code>"orderBy": "rand"</code> manually using the Code Editor.</li>
</ul>
<h3>Example use case</h3>
<p>Want your homepage, blog, quotes site, testimonials, or featured-section to show<br />
<strong>a different post every time the page loads?</strong></p>
<p>Install this plugin <span aria-hidden="true" class="wp-exclude-emoji">→</span> open the template <span aria-hidden="true" class="wp-exclude-emoji">→</span> switch to Code Editor <span aria-hidden="true" class="wp-exclude-emoji">→</span> set <code>"orderBy": "rand"</code>.</p>


Random Posts for Query Loop Block

<h3>Usage</h3>
<p>Once it’s installed, go to Settings -> Reading section, scroll to the bottom, and choose an orderby and order option.</p>


Default Post Sort

I'm glad I came across this plugin. It does exactly what the title says and nothing more which is what I want in a plugin. 

Simple and straightforward. Great plugin.

Provides a user interface for setting a default post order.
