Obfuscate email addresses

As most of you know, spam bots are constantly scanning the internet in order to find emails to spam. Of course, you don’t want to receive spam, but what if you need to display your email (or someone else) on your blog? This code will create a shortcode which will obfuscate email adresses. As usual, let’s start by creating the shortcode: paste the code into your functions.php file.

 
function cwc_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', 'cwc_mail_shortcode');

Then you can use the shortcode, which is pretty easy:

[mailto]email@yourdomain.com[/mailto]
