The Query Loop block in WordPress does not include a “Random” ordering option in the sidebar UI. 
However, WordPress core does support <code>orderby = rand</code> in <code>WP_Query</code>.
The problem: 
Using <code>"orderBy": "rand"</code> inside a Query Loop block can cause the Site Editor preview to fail, because <code>rand</code> is not included in the REST API schema for posts.
This plugin fixes that by extending the REST API orderby enum so the editor recognizes <code>"rand"</code> as valid.
<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 not do</h3>
<ul>
<li>It does not add a “Random” option to the Query Loop UI dropdown. 
(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>
Want your homepage, blog, quotes site, testimonials, or featured-section to show 
a different post every time the page loads?
Install this plugin → open the template → switch to Code Editor → set <code>"orderBy": "rand"</code>.

Random Posts for Query Loop Block

Adds "rand" to the REST API orderby options so the Query Loop block can use random post order safely without breaking the Site Editor preview.

Most people don’t need this plugin. Most wouldn’t notice a difference if they had it. All it does is change the default sort order of a WP_Query from posts.post_date to posts.post_date_gmt — that is, sort on the GMT timestamp of a post rather than the local time zone.
Who needs this? People who switch time zones frequently. People running a network installation of WordPress where they want to be able to aggregate posts from all their network blogs easily, and in the right order. I don’t know. I wrote it for FreeThoughtBlogs.com, so their “most recent posts” sidebar would stop showing only posts from a few blogs in early time zones. If it works for you, great.
I have every hope that this plugin will be made obsolete by the default sort order being changed in the WordPress core. I can think of no good reason why comments are sorted by GMT but posts by local time.
For all I know, this plugin works with older versions than 3.0. I’ve only tested it with 3.2.1.

Posts by GMT

Changes the default sort order for posts from post_date to post_date_gmt.
