How To Create a Shortcode That Obscures Email Links

Are you looking for a way to create a shortcode that obscures email links? This snippet will let you easily and quickly obscure an email address link to make it harder for spam bots to find your email address.

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

<?php

// Obfusticate email addresses
function obf_mail_shortcode( $atts , $content=null ) {
    for ($i = 0; $i < strlen($content); $i++) $encodedmail .= "&#" . ord($content[$i]) . ';';
    return '<a href="mailto:'.$encodedmail.'">'.$encodedmail.'</a>';
}
add_shortcode('mailto', 'obf_mail_shortcode');

?>

You can wrap this shortcode around an email address to obscure the email address.

[mailto][email protected][/mailto]
