This plugin gives you <code>[query]</code> shortcode which enables you to query and output any posts filtered by specific attributes.
<h4>Usage</h4>
You can use most parameters supported by <a href="https://codex.wordpress.org/Class_Reference/WP_Query" rel="nofollow ugc">WP_Query class</a> to filter the posts; you can query for specific post types, categories, tags, authors, etc.
<h4>Other supported parameters</h4>
Aside from WP_Query parameters, the shortcode also supports the following additional parameters:
<ul>
<li>featured: to query for sticky posts which by default are excluded from the query.</li>
<li>thumbnail_size: to specify the size of the {THUMBNAIL} images. You can use <a href="https://codex.wordpress.org/Function_Reference/add_image_size#Reserved_Image_Size_Names" rel="nofollow ugc">built-in image sizes</a> or custom ones you’ve defined.</li>
<li>content_limit: to limit the number of words of the {CONTENT} var; by default it’s “0” which means it outputs the whole content.</li>
<li>posts_separator: text to display between individual posts.</li>
<li>lens: custom output template – see description below.</li>
<li>twig_template: output template using Twig templating engine – requires the Timber library.</li>
</ul>
<h4>Formatting the output</h4>
You can define how you want to format the output inline within an opening <code>[query]</code> and closing <code>[/query]</code> tag. 
Available keywords are: TITLE, CONTENT, AUTHOR, AUTHOR_URL, DATE, THUMBNAIL, CONTENT, COMMENT_COUNT.
The following example will display the latest 5 posts from the category with the ID of 3, showing a post title and comment count, with a link to the post: 
 [query posts_per_page=”5″ cat=”3″]
<h3><a href="{URL}" rel="nofollow ugc">{TITLE} ({COMMENT_COUNT})</a></h3>
[/query]
Grid display
With the “cols” parameter you can display the output in a grid. 
 [query posts_per_page=”3″ cols=”3″] {THUMBNAIL}
<h3>{TITLE}</h3>
{CONTENT} [/query] 
will display the latest 3 posts in the defined template, in 3 columns. 
The plugin will automatically divide the grid into rows based upon the ‘posts_per_page’ option, divided by the ‘cols’ option.
<h4>Lenses (output templates)</h4>
With the “lens” parameter you can customize the display of the query results using a template. Some basic lenses/templates are provided:
<ul>
<li>ul: unordered list of linked post titles.</li>
<li>ul-title-date: same as ‘ul’, but also displays the posted date.</li>
<li>article-excerpt: series of articles, with a header containing the linked post title, and the excerpt.</li>
<li>article-excerpt-date: same as ‘article-excerpt’, but also displays the posted date.</li>
<li>cards: displays the post thumb above the header with linked post title, followed by the excerpt.</li>
</ul>
Bootstrap lenses
Some pre-defined lenses/templates are provided which use JavaScript Components from the <a href="http://getbootstrap.com/" rel="nofollow ugc">Bootstrap</a> CSS framework. The generated markup is compliant with the 5.x version of Bootstrap.
This feature relies on Bootstrap library to be already loaded on the page, the plugin does not include it.
If you’re using a Bootstrap-based theme, this should work; otherwise you can use the <a href="https://wordpress.org/extend/plugins/bootstrap/" rel="ugc">Bootstrap plugin</a>).
<a href="http://getbootstrap.com/javascript/#tabs" rel="nofollow ugc">Tabs</a>
This will show the latest 3 posts in a tabbed widget. 
 [query posts_per_page=”3″ lens=”tabs”]
<a href="http://getbootstrap.com/javascript/#tabs" rel="nofollow ugc">Accordion</a>
This will create an accordion widget of all our posts from the “faq” post type. 
 [query posts_per_page=”0″ post_type=”faq” lens=”accordion”]
<a href="http://getbootstrap.com/javascript/#carousel" rel="nofollow ugc">Carousel</a>
This creates a carousel of latest five featured posts: 
 [query posts_per_page=”5″ featured=”true” lens=”carousel”]
Custom Lenses/templates
You can create your own custom templates and put them into one of these pre-defined folder names within your theme:
<ul>
<li>‘query-shortcode-templates’</li>
<li>‘partials/query-shortcode-lenses/’</li>
<li>‘html/lenses/’</li>
</ul>
Or simply specify your own subfolder in the ‘lens’ parameter: 
 [query lens=”folder/template-name”]
<h4>Twig Template Support</h4>
Starting with version 0.4, you can use Twig templates for your output. Support for Twig is provided by the <a href="https://github.com/timber/timber" rel="nofollow ugc">Timber</a> library.
This requires that Timber 2.x be installed as a <a href="https://timber.github.io/docs/v2/installation/installation/" rel="nofollow ugc">Composer dependency</a>.
To use a Twig template for your query output, simply use the 'twig_template' parameter instead of the 'lens' parameter, and provide the path to your template. By default, Timber looks within the <code>views</code> folder in your active theme. You can <a href="https://timber.github.io/docs/v2/guides/template-locations/#changing-the-default-folder-for-twig-files" rel="nofollow ugc">change the default template location</a> in Timber.
Examples:
<pre><code>[query twig_template="template-name.twig"]
[query twig_template="folder/template-name.twig"]
</code></pre>

For admins, developers, and support staff, Debug This provides a ton of information about your WordPress installation, all from the front-end admin bar.
<ul>
<li>The current WP_Query object</li>
<li>Blog info and options</li>
<li>Embed providers</li>
<li>Files in rendered HTML (CSS, images, JavaScript)</li>
<li>Filters and actions</li>
<li>Images sizes</li>
<li>Globals and constants</li>
<li>Menus</li>
<li>Object cache stats</li>
<li>Plugins, must-use plugins, and dropins</li>
<li>Rewrite rules</li>
<li>Queries</li>
<li>PHP and server information</li>
<li>Post attachments</li>
<li>Post types</li>
<li>Scripts and styles enqueued</li>
<li>Shortcodes</li>
<li>Sidebars and widgets</li>
<li>Taxonomies and terms</li>
<li>Themes</li>
<li>Users</li>
<li>WP cron schedules and jobs</li>
<li>WP debug log</li>
</ul>
Debug This helps you save time and effort when trying to figure out what’s going on. Instead of hardcoding debug snippets or writing complex unit 
tests for small functionality, you can simply bring to the surface what you need right from the admin bar.
For example, when viewing a single post, you can see:
<ul>
<li>a list of post attachments,</li>
<li>which menus and sidebars are being displayed,</li>
<li>the post type, post fields, and meta data,</li>
<li>the current query variables and query string,</li>
<li>the rewrite rules applied,</li>
<li>the author,</li>
<li>the terms,</li>
<li>and much more.</li>
</ul>
<h3>Extend</h3>
<h4>Debug This Functions</h4>
New debug modes can be created easily:
<pre><code>add_debug_extension(
 $mode,
 $menu_label,
 $description,
 $callback,
 $group = 'General'
);
</code></pre>
Example
<pre><code>add_debug_extension(
 'actions',
 __('Actions', 'debug-this'),
 __('$wp_actions contains all active registered actions', 'debug-this'),
 'foo_callback',
 'Filters And Actions'
);
function foo_callback($buffer, $template){
 global $wp_actions;
 $debug = print_r($wp_actions, true);
 return $debug;
}
</code></pre>
You can add links to the header of a debug mode page. Place this code within your debug callback function.
<pre><code>add_debug_header_link('http://urltolink', 'Link Label');
</code></pre>
Extensions can be removed as well using <code>remove_debug_extension($mode);</code>
No PRE Tags
If you don’t want your debug output to be enclosed in PRE tags, simply set the following in your extension:
<pre><code>Debug_This::$no_pre = true;
</code></pre>
Saved Queries and Execution Time
Retrieve saved queries and execution time by using the following static properties:
<ul>
<li><code>Debug_This::$execution_time</code></li>
<li><code>Debug_This::$queries</code> – SAVEQUERIES must defined as true</li>
</ul>
URL Helpers
<ul>
<li><code>Debug_This::get_current_debug_url()</code> – current URL with the debug query</li>
<li><code>Debug_This::get_escape_url()</code> – used for the debug escape link that links to original page URL</li>
</ul>
<h4>WP Actions</h4>
<ul>
<li><code>debug_this</code> – receives the $mode arg – outputs the debug code sent from the extension modes. The default action is set to priority 5. This allows you to prepend or append any output without conflict using less or greater priorities.</li>
</ul>
<h4>WP Filters</h4>
There are a few filters you can use to customize Debug This to your needs:
<ul>
<li><code>debug_this_template</code> – receives $template arg – Use your own template</li>
<li><code>debug_this_default_mode</code> – receives $mode arg – Alters the mode for the parent DT admin bar button link.</li>
<li><code>debug_this_output</code> – receives $output, $mode args – Filter debug content before it’s rendered</li>
</ul>
<h4>JavaScript</h4>
To access the built-in Debug This JS functionality, enqueue your custom script with the dependency set to <code>debug-this</code>. Your script will inherit a jQuery dependency.
Object: debugThis
<ul>
<li><code>debugThis.mode</code> – current mode</li>
<li><code>debugThis.defaultMode</code></li>
<li><code>debugThis.template</code> – current included template</li>
<li><code>debugThis.queryVar</code> – the defined query string variable</li>
</ul>
Functions:
<ul>
<li><code>isDebug()</code></li>
<li><code>getDebugMode()</code> – uses <code>isDebug()</code></li>
</ul>
Events:
A jQuery <code>debug-this</code> event is fired from the footer. You can hook into this event with the following;
<pre><code>jQuery(document).bind('debug-this', function(event, debugThis){
 console.log(debugThis);
});
</code></pre>
<h4>Helper Functions</h4>
There are three included functions to help you work with files.
<ul>
<li><code>debug_this_get_file_ownership($file)</code> – returns <code>array('name' => $name, 'group' => $group)</code></li>
<li><code>debug_this_get_file_perms($file)</code> – returns string – Example: 0775</li>
<li><code>debug_this_convert_perms_to_rwx($perms)</code> – returns string – converts permission number to RWX format – Example: 0755 folder becomes drwxr-xr-x</li>
</ul>

Very nice, even the phpinfo() colors are displayed correctly.

Great plugin

Peek under the hood with sixty debugging reports just one click away.
