Setting custom link text
[email-obfuscate email=”bob@example.com” link_title=”Email Bob!”]
*Setting custom link title attribute”
[email-obfuscate email=”bob@example.com” tag_title=”Email Bob!”]
Using every available setting (this example shows their default values)
[email-obfuscate email=”bob@example.com” linkable=”1″ link_title=”” use_htmlentities=”1″ use_noscript_fallback=”1″ noscript_message=”Please enable JavaScript to see this field.”]
Usage from a template or plugin
Below is a snippet that you can use in any template or plugin to apply the same obfuscation to an email as using the shortcode:
if(function_exists(‘eos_obfuscate’)) 
{ 
 echo eos_obfuscate(array(’email’ => $email, ‘link_title’ => ‘Email Bob!’)); 
} 
else 
{ 
 echo $email; 
}
If the plugin is not enabled, the email address will just pass through and output in cleartext.

Obfuscate your email address or other sensitive information with a shortcode to prevent spam and automated harvesting of data.

This email cloaking method:
<ul>
<li>is accessible for people browsing with screen readers (e.g., blind people); </li>
<li>degrades gracefully for browsers without JavaScript; </li>
<li>works just like a normal, clickable email address for browsers with JavaScript enabled; and</li>
<li>requires no shortcodes.</li>
</ul>
Email addresses in the form <code>email AT address DOT com</code> are converted to a clickable version, <a href="mailto:email@address.com" rel="nofollow ugc">email@address.com</a>, if JavaScript is enabled. If JavaScript is not enabled (such as for screen readers), then the email address in the form <code>email AT address DOT com</code> is still readable to humans.
