<?php
class Ncr_Custom_Login_Captcha extends Ncr_No_Captcha_Recaptcha {
public static function initialize() {
// initialize if login is activated
if ( isset(self::$plugin_options['captcha_login']) && self::$plugin_options['captcha_login'] == 'yes') {
// add captcha header script to WordPress header
add_action( 'wp_head', array( __CLASS__, 'header_script' ) );
// adds the captcha to the custom login form
add_action( 'custom_captcha_login', array( __CLASS__, 'display_captcha' ) );
// authenticate the captcha answer
add_action( 'wp_authenticate_user', array( __CLASS__, 'validate_captcha_custom_login' ), 10, 2 );
}
}
/**

* @return WP_Error|WP_user
*/
public static function validate_captcha_custom_login( $user, $password ) {
if ( ! isset( $_POST['g-recaptcha-response'] ) || ! self::captcha_verification() ) {
// Pop error message into $error_msg
}
return $user;
}
}

require_once dirname(__FILE__). '/custom-login.php';
Ncr_Custom_Login_Captcha::initialize();
—————————–
On the form in question I have added a fire action
{do_action( 'custom_captcha_login' )}
I think i just found the answer…
`/** reCAPTCHA header script */
public static function header_script() {
$lang_option = self::$language;
// if language is empty (auto detected chosen) do nothing otherwise add the lang query to the
// reCAPTCHA script url
if ( isset( $lang_option ) && ( ! empty( $lang_option ) ) ) {
$lang = “?hl=$lang_option”;
} else {
$lang = null;
}
echo ‘<script src=”https://www.google.com/recaptcha/api.js’ . $lang . ‘” async defer></script>’ . “\r\n”;
}
/**
* Enqueue the Google ReCAPTCHA script using the WP system.
*
* @since 1.0.3
*/
public static function enqueue_header_script() {
// if language is empty (auto detected chosen) do nothing otherwise add the lang query to the
// reCAPTCHA script url
if ( ! empty( self::$language ) ) {
$lang = “?hl={self::$language}”;
} else {
$lang = ”;
}
$src = ‘https://www.google.com/recaptcha/api.js’ . $lang;
wp_enqueue_script( self::$script_handle, $src, false, false, true );
}`
Its not getting called into the custom login page
Now it seems when validation fails I get a 500 server error
PHP Fatal error: Class name must be a valid object or a string
Update to custom-login.php
Good news, the login is working only problem is getting the error message to display. So far no error message is showing.
<?php
class Ncr_Custom_Login_Captcha extends Ncr_No_Captcha_Recaptcha {
public static function initialize() {
// initialize if login is activated
if ( isset(self::$plugin_options['captcha_login']) && self::$plugin_options['captcha_login'] == 'yes') {
// add captcha header script to WordPress header
add_action( 'wp_head', array( __CLASS__, 'header_script' ) );
// adds the captcha to the custom login form
add_action( 'custom_captcha_login', array( __CLASS__, 'display_captcha' ) );
// authenticate the captcha answer
add_action( 'wp_authenticate_user', array( __CLASS__, 'validate_captcha_custom_login' ), 10, 2 );
}
}
/**
* Verify the captcha answer
*
* @param $user string login username
* @param $password string login password
*
* @return WP_Error|WP_user
*/
public static function validate_captcha_custom_login( $user, $password ) {
if ( ! isset( $_POST['g-recaptcha-response'] ) || ! self::captcha_verification() ) {
// Pop error message into $error_msg
echo $error_message;
}
return $user;
}
}
