Using custom parameters with login page

maciej.wisniowski

Hi

I have a use case where I'd like to customize the FA login page based on the parameters sent in the request. I mean that my application will add an extra parameter during redirect to the FusionAuth /oauth2/authorize URL. I know that I can access request parameters in the login page template (OAuth authorize) but as soon as a user tries to log in and an error occurs (eg. invalid password) all the request parameters are gone (page reload).

So far I've found that I can use the user_code parameter (as I'm not using device flow) to achieve what I need. user_code is available all the time in the template, even after page reload, but is there any other option to do it? Some extra user_parameters would be great.

Answering to myself. Seems I can do the following:

[#if request.getParameter('custom_parameter')??]
          [#global custom_parameter = request.getParameter('custom_parameter')?string /]
          [@helpers.hidden name="custom_parameter" /]
[/#if]
</form>

which just passes the parameter in the input field making it available after the form submit

I did not know you could do that. Thanks for sharing your solution!
