Validates an auth code generated with Finisher\GenerateAuthCode.

If you have a registration form which sends an auth code to the user by email, you can use this PreProcessor to validate the auth code directly on the form page with no need to write additional PHP code.

These steps are required to make a working auth code validation:

• Create the record using Finisher\DB. Make sure you set the record inactive at first (e.g. set hidden to 1).
• Send an auth code generated with Finisher\GenerateAuthCode to the user.
• Validate the auth code with PreProcessor\ValidateAuthCode. Configure the used hiddenField in TypoScript.
• If the auth code is valid, Formhandler sets the hiddenField to 0 and redirects the user to the specified redirectPage. If the code is invalid, the user is redirected to the specified errorRedirectPage.

preProcessors {
  5 {
    class = PreProcessor\LoadGetPost
  }
  10 {
    class = PreProcessor\ValidateAuthCode
    config {
     
      # Redirect to this page if the validation is successful
      redirectPage = 50

      # Redirect to this page if there is an error
      errorRedirectPage = 51
    }
  }
}
