How to automatically hide email adresses from spambots on your WordPress blog

Paste the following code into your functions.php file. Once you saved the file, the code will filter content and widget content to hide all e-mails from spambots.

function security_remove_emails($content) {
    $pattern = '/([a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4})/i';
    $fix = preg_replace_callback($pattern,"security_remove_emails_logic", $content);

    return $fix;
}
function security_remove_emails_logic($result) {
    return antispambot($result[1]);
}
add_filter( 'the_content', 'security_remove_emails', 20 );
add_filter( 'widget_text', 'security_remove_emails', 20 );
