<p>For admins, developers, and support staff, <strong>Debug This</strong> provides a ton of information about your WordPress installation, all from the front-end admin bar.</p>
<ul>
<li><em>The current WP_Query object</em></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>
<p><strong>Debug This</strong> helps you save time and effort when trying to figure out what’s going on. Instead of hardcoding debug snippets or writing complex unit<br />
tests for small functionality, you can simply bring to the surface what you need right from the admin bar.</p>
<p>For example, when viewing a single post, you can see:</p>
<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>
<p>New debug modes can be created easily:</p>
<pre><code>add_debug_extension(
    $mode,
    $menu_label,
    $description,
    $callback,
    $group = 'General'
);
</code></pre>
<p><strong>Example</strong></p>
<pre><code>add_debug_extension(
    'actions',
    __('Actions', 'debug-this'),
    __('$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 $debug;
}
</code></pre>
<p>You can add links to the header of a debug mode page. Place this code within your debug callback function.</p>
<pre><code>add_debug_header_link('http://urltolink', 'Link Label');
</code></pre>
<p>Extensions can be removed as well using <code>remove_debug_extension($mode);</code></p>
<p><strong>No PRE Tags</strong></p>
<p>If you don’t want your debug output to be enclosed in PRE tags, simply set the following in your extension:</p>
<pre><code>Debug_This::$no_pre = true;
</code></pre>
<p><strong>Saved Queries and Execution Time</strong></p>
<p>Retrieve saved queries and execution time by using the following static properties:</p>
<ul>
<li><code>Debug_This::$execution_time</code></li>
<li><code>Debug_This::$queries</code> – SAVEQUERIES must defined as true</li>
</ul>
<p><strong>URL Helpers</strong></p>
<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>
<p>There are a few filters you can use to customize Debug This to your needs:</p>
<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, $mode args – Filter debug content before it’s rendered</li>
</ul>
<h4>JavaScript</h4>
<p>To access the built-in Debug This JS functionality, enqueue your custom script with the dependency set to <code>debug-this</code>. Your script will inherit a jQuery dependency.</p>
<p><strong>Object: debugThis</strong></p>
<ul>
<li><code>debugThis.mode</code> – current mode</li>
<li><code>debugThis.defaultMode</code></li>
<li><code>debugThis.template</code> – current included template</li>
<li><code>debugThis.queryVar</code> – the defined query string variable</li>
</ul>
<p><strong>Functions:</strong></p>
<ul>
<li><code>isDebug()</code></li>
<li><code>getDebugMode()</code> – uses <code>isDebug()</code></li>
</ul>
<p><strong>Events:</strong></p>
<p>A jQuery <code>debug-this</code> event is fired from the footer. You can hook into this event with the following;</p>
<pre><code>jQuery(document).bind('debug-this', function(event, debugThis){
    console.log(debugThis);
});
</code></pre>
<h4>Helper Functions</h4>
<p>There are three included functions to help you work with files.</p>
<ul>
<li><code>debug_this_get_file_ownership($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>


Debug This

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

Great plugin

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

<p>Toggles human and machine language (aka ID-s) on admin pages.</p>
<h4>Only for development!</h4>
<p>This plugin shows you the ID-s of almost all form fields including selects, checkboxes and radio buttons like in <code>wp-admin/options.php</code>.</p>
<p>It works only on WordPress Settings API-like formatted — not necessarily API generated — admin pages. E.g. <code><input></code> elements cannot be wrapped in <code><span></code>.</p>
<h4>Activation</h4>
<p>You can find the plugin’s checkbox in standard Screen Options (upper right corner). This checkbox could be overwritten — thus hidden — by poorly written plugins. To restrict Machine Language to a certain admin page, copy this to your <code>wp-config.php</code>:</p>
<pre><code>define( 'MACHINE_LANGUAGE_HOOK', 'load-options-reading.php' ); </code></pre>
<p>For example this line causes to run only on Settings / Reading.</p>
<h4>Features</h4>
<ul>
<li>Basically all input ID-s are displayed in place of labels, actually <code>for</code> attributes of labels</li>
<li><code>select</code>-s get a title showing all option values comma separated (hover over <code>select</code>-s with your mouse)</li>
<li><code>option</code>-s get values appended in the form of “original option text|value”</li>
<li>Radio button labels will show: “name|value”</li>
<li>Descriptions (<code>p</code>-s and <code>span</code>-s with “description” class) will be hidden, this way Machine Language will clean up all admin pages, descriptions are hidden by CSS, so there’s no <a href="http://en.wikipedia.org/wiki/Flash_of_unstyled_content" rel="nofollow ugc">FOUC</a></li>
</ul>
<h4>Other notes</h4>
<ul>
<li>Radio buttons or checkboxes with empty value are displayed with the “Empty Set” Unicode character: “? ” (U+2205) ( e.g. Settings / Permalinks / Default )</li>
<li><code>select</code>-s with empty values are not</li>
<li>The plugin’s checkbox in Screen Options is effective immediately</li>
<li>The code is designed as a must use plugin, so there is no separated Javascript or CSS file</li>
<li>State of Machine Language is saved as a user option so it is a per user setting</li>
</ul>
<h4>Links</h4>
<p>Development goes on on <a href="https://github.com/szepeviktor/machine-language" rel="nofollow ugc">GitHub</a>.</p>
