recaptcha Verify() method returns invalid-input-secret

[engharb]

Hello,

I am starting using this lib, and when I submit my form and verify the secret I got always 'invalid-input-secret' ?

Do you have any idea?

Please check that you are passing the full key in the right format as retrieved from https://www.google.com/recaptcha/admin#list

That error occurs, according to https://developers.google.com/recaptcha/docs/verify

The secret parameter is invalid or malformed.

I have the same problem and have never gotten this to work. I pass the correct key but no success.

I encountered the same error and was able to resolve it.
The thing is that you should use two different secret keys, one on the client-side, and another one (not the same) on the server-side.

When you open secret keys in google page (https://www.google.com/recaptcha/admin/site/XXXXXXXXX/setup), then you'll see two keys: first one is for client-side, the second one is for Verify() method on the server-side.

Same for me even using different key one for client side(site key) and other for server verification(secret key). Still I'm getting the error code ['invalid-input-secret']

Maybe a little late to the party. But changing the server side ReCaptcha class fixed it for me.

Original code

public function ReCaptcha ($secret) {
        if ($secret == null || $secret == "") {
            die("To use reCAPTCHA you must get an API key from <a href='"
                . self::$_signupUrl . "'>" . self::$_signupUrl . "</a>");
        }
        $this->_secret=$secret;
}

changed to

public function __construct($secret) {
        if ($secret == null || $secret == "") {
            die("To use reCAPTCHA you must get an API key from <a href='"
                . self::$_signupUrl . "'>" . self::$_signupUrl . "</a>");
        }
        $this->_secret=$secret;
       
    }

Hope that helps someone.

Thanks @faseelsaeed, changing constructor method from same as class to __construct solved my problem.
