Obfuscate E-mail

Version:

Description:

Obfuscate e-mail addresses in text and links via random hex and ASCII code substitution while retaining the appearance and functionality of hyperlinks.

Notes:

Example (of full obfuscation):

<a href="mailto:person@example.com">person@example.com</a>

Would be translated into something like this:
<a href="mailto:&#112;&#101;&#114;&#115;&#x6F;&#110;&#x40;&#101;&#x78;&#x61;&#x6D;&#112;&#x6C;&#101;&#x2E;&#x63;om">&#112;&#x65;&#x72;&#x73;&#111;&#110;&#64;&#x65;&#x78;&#x61;&#109;&#x70;&#108;&#x65;&#x2E;&#99;om</a>

However, in your browser it would appear to you as it does prior to obfuscation, and the link for the e-mail would still work. Theorectically, however, spammers would have a somewhat more difficult time harvesting the e-mails you display or link to in your posts.

Installation:
  1. Download the file obfuscate-email.zip and unzip it into your /wp-content/plugins/ directory.
    -OR-
    Copy and paste the the code ( obfuscate-email.phps ) into a file called obfuscate-email.php, and put that file into your /wp-content/plugins/ directory. Please ensure you do not introduce any spaces or other characters before the <?php or after the ?>
  2. Optional: Change configuration options in the file to your liking. In-code comments should help you there.
  3. Activate the plugin from your WordPress admin ‘Plugins’ page.
Functions:

function c2c_obfuscate_email( $text, $encode_everything = 1 )

  • $text : Text to be scanned for e-mail obfuscation
  • $encode_everything: optional; if 1 then full obfuscation (as seen in the Notes section) will occur. If set to 0, then only very minimal obfuscation occurs, i.e. “@” gets replaced with &#064; and “.” gets replaced with &#046;
Tips & Examples:

(See notes section above)

Mads: Yes, it works on pages in WP.

Pariah: Actually, it does apply to comments. I simply didn’t have the plugin activated on my site. It is now, so feel free to test again.

Simpler Solution:

Just copy this where ever you need it


$email_address = "foo@bar.com";
$email_address = substr( chunk_split( bin2hex( " ".$email_address ), 2, ";&amp;#x" ), 3,-3);

It’s a wonderful plugin.

For several reasons I have put email-addresses in the post meta (such as post_custom(’email’)). They will be published later like

echo post_custom(’email’);
echo ‘” TARGET=”_blank”>Email

Is there any way your plugin can manage this (it does not work with 2.1.3)?

Thanks
Tom
