<p>Create your own custom variables to manage information on your website such as:</p>
<ul>
<li>Phone numbers</li>
<li>Addresses</li>
<li>Social media links</li>
<li>HTML snippets</li>
<li>And anything else<br />
test</li>
</ul>
<p>Easily access them globally in WordPress and PHP.</p>
<h4>Why you need it</h4>
<p>Rather than having to change something like an email address across multiple pages, you can do it in one place. Avoid the pitfalls of hard coding information in your WordPress theme that is likely to change.</p>
<h4>Why it’s better</h4>
<ul>
<li>Your variables are stored and retrieved locally without any calls to the database. That means faster load times for your pages!</li>
<li>Variables can be accessed easily in PHP from the global scope.</li>
</ul>
<h3>Usage</h3>
<p>Display your variables using the shortcode syntax:</p>
<pre><code>[cgv variable-name]
</code></pre>
<p>Or using the superglobal in PHP:</p>
<pre><code><?php echo $GLOBALS['cgv']['variable-name'] ?>
</code></pre>


Custom Global Variables

By far the best one "Variables" plugin. I tested some others, those were based on database and because of failed caching I experienced problems. Since the day I moved to this plugin, all problems disappeared :)  I love the simplicity :)



Best of the ones I tested

Easily create custom variables that can be accessed globally in Wordpress and PHP. Retrieval of information is extremely fast, with no database calls.
