This is the official github repository of the WP reCaptcha integration plugin plugin. This repo might contain untested and possibly unstable or insecure code. So use it on your own risk.
- Secures login, signup and comment form with a recaptcha.
- Supports visible Google recaptcha. Invisible recapture planned.
- Tested with up to WP 4.8, WooCommerce 2.3.5, cformsII 14.14
- Can be used together with Ninja Forms and Contact Form 7 recaptchas.
Fires after a recaptcha has been checked.
// will redirect to http://honeypot.org when captcha test fails.
function my_recaptcha_checked( $check_successful ) {
if ( ! $check_successful )
wp_redirect( 'http://honeypot.org' );
}
add_filter('wp_recaptcha_checked','my_recaptcha_checked');
Disable captcha if it has been solved once.
// safely start a session
function my_session_start( ) {
$sid = session_id();
if ( empty( $sid ) ) {
session_start();
}
}
add_action('init','my_session_start',1);
// don't requiere captcha, if session says so
function my_wp_recaptcha_required( $is_required ) {
if ( isset( $_SESSION['recaptcha_solved'] ) && $_SESSION['recaptcha_solved'] )
return false;
return $is_required;
}
add_filter('wp_recaptcha_required' , 'my_wp_recaptcha_required');
// store in session if captcha solved
function my_wp_recaptcha_checked( $check_successful ) {
if ( $check_successful )
$_SESSION['recaptcha_solved'] = true;
}
add_action('wp_recaptcha_checked','my_wp_recaptcha_checked');
Returns whether to show a recaptcha or not.
// will disable recaptcha for nice spambots
function my_recaptcha_required( $is_required ) {
if ( is_nice_spambot() )
return false;
else if ( is_ugly_spambot() )
return true;
else
return $is_required;
}
add_filter('wp_recaptcha_required','my_recaptcha_required');
HTML to be showed when entering a recaptcha is not required.
// will disable recaptcha for nice spambots
function my_recaptcha_disabled_html( $html ) {
return 'Not for you, my friend!';
}
add_filter('wp_recaptcha_disabled_html','my_recaptcha_disabled_html');
Override the recaptcha language attribute. Possible return values are depending on the languages supported by the current captcha flavor.
Note: This filter is used internally in order to set the language according to the current WP language. I cannot imagine a real-world use case, but for the sake of completeness I documented it here.
// will set language to french if language is german
// (French is considered a very elegant and pleasing language in germany,
// your vistors from DE will love you for it!)
function my_recaptcha_language( $lang ) {
if ( $lang == 'de' )
return 'fr';
return $lang;
}
add_filter('wp_recaptcha_language','my_recaptcha_language');
Use this to disable loading of the recaptcha scripts.
// Will disable script loading on the frontend
if ( ! is_admin() && ! in_array( $GLOBALS['pagenow'], array( 'wp-login.php', 'wp-register.php' ) ) )
add_filter('wp_recaptcha_do_scripts','__return_false');
Use this to disable the css on the login page.
// Will disable plugin css on the login page
add_filter('wp_recaptcha_print_login_css','__return_false');
I order to integrate recaptcha in your custom forms, there are six filters added in order to get the recaptcha HTML:
recaptcha_htmllostpassword_recaptcha_htmllogin_recaptcha_htmlsignup_recaptcha_htmlcomments_recaptcha_htmlwc_checkout_recaptcha_html
Use apply_filters('feature_recaptcha_html','') to retrieve the HTML.
// $recaptcha_html will hold the recaptcha HTML if
// a captcha validation is required AND recaptcha is enabled for comment forms
$recaptcha_html = apply_filters( 'comments_recaptcha_html' , '' );
