Error: Class 'ReCaptcha\ReCaptcha' not found in recaptcha_captcha_validation() (line 162

Variation of #5 and #24 worked for me with D9.5.10, recaptcha 8.x-3.2:

Added these lines to recaptcha.module after the last use statement:

require_once dirname(__FILE__) . '/src/ReCaptcha/ReCaptcha.php';
require_once dirname(__FILE__) . '/src/ReCaptcha/RequestMethod.php';
require_once dirname(__FILE__) . '/src/ReCaptcha/RequestParameters.php';
require_once dirname(__FILE__) . '/src/ReCaptcha/Response.php';

Copied these class files from version: v8.x-3.1 of the module into recaptcha/src/ReCaptcha/

Solution from #61 worked for me. Installing with composer command solved the issue:

composer require 'drupal/recaptcha:^3.0'

I have older Drupal 8.9.x website where update would be problematic so I installed recaptcha at first by hand, but came across this error.

I duplicated composer.json file somewhere locally, run the command, copied vendor directory to live website and it started to work.

the solution in #76 worked for me , added the google directory into vendor directory and then added those lines to the recaptcha module as well as the files he includes in the zip to the src/recaptcha directory

Same error for me with Drupal 10 and the latest version of this module.

RE: #79

The Ludwig integration is added recently ✨ reCAPTCHA - Ludwig integration Fixed , so the latest 8.x-3.x-dev can be installed with Ludwig as well. Of course, the Composer is highly recommended whenever possible.

I believe this issue can be closed as outdated. If you have a proper Composer installation or the proper Ludwig + reCAPTHA 8.x-3.x-dev installation and you still experience this issue please feel free to reopen.

Hi

The error in forms has now reappeared when a non-authorised user submits a form.

Just upgraded to ReCaptcha 8.x-3.4 under Drupal 10.3.2
Running Ludwig 2.0.7 & CAPTCHA 8.x-1.15

I am still installing modules via Drupal...
Will have to upgrade to Composer sometime but it's a major pain as it's a shared server (home directory cannot be changed, etc.).

The following error whenever a form is submitted:
Error: Interface "ReCaptcha\RequestMethod" not found in include() (line 13 of /home/progres1/public_html/modules/recaptcha/src/ReCaptcha/RequestMethod/Drupal8Post.php).

The original lines in ludwig.json are present:

{
  "require": {
    "google/recaptcha": {
      "version": "v1.2.4",
      "url": "https://github.com/google/recaptcha/archive/1.2.4.zip"
    }
  }
}

Ludwig Packages tells me that google/recaptcha is downloaded.

Have I missed something?

Many thanks,
Andrew

Solution in #76 worked for me with Drupal core 10.3.2 and reCAPTCHA 8.x-3.4

Hi Alex

Thanks very for the note.
It now works!

Pity it doesn't stay like that after each upgrade...

Much appreciated,

Andrew

Re: #81+

The patch #2 in the new added related issue should help. Please test.
