Written as a platform for plugin developers, this simple-yet-powerful plugin allows you to run a custom WP_Query using shortcode, then display the results any way imaginable using compatible nested shortcodes.
<h4>How It Works</h4>
Add the following shortcode to any WordPress post or page:
<pre><code>[wpquery orderby="rand"] [wpq_index] [/wpquery]
</code></pre>
In the example above, the <code>[wpquery]</code> shortcode performs a WP_Query using orderby=”rand” to display the results in random order. A full list of query parameters can be found here: <a href="https://codex.wordpress.org/Class_Reference/WP_Query#Parameters" title="WP_Query" rel="nofollow ugc">WP_Query</a>.
Next, the nested <code>[wpq_index]</code> shortcode displays the results of the custom WP_Query as an unordered list of post title links.
<h4>Why It Rocks</h4>
Written as a platform for plugin developers, this simple-yet-powerful plugin allows developers to write compatible plugins that manipulate the way post data is displayed – without needing to write functions and shortcode parameters to first retrieve the post data.
The <code>[wpq_index]</code> shortcode function included in this plugin is just a simple example of what it can do. Any plugin that performs a WP_Query could be rewrtitten and optimized to work with this plugin, eliminating a lot of unnecessary code.
Best of all, this plugin gives users total control over the WP_Query being performed!
