It doesn't matter the previous page who links to this page as i need to add params to url according to the form fields typed in the user form at the present page
Unfortunately, i'm the only one available today. Perhaps I can ask christian to assist with this, however he won't be available until sunday.
I took a look at the link you sent but this isn't working.
I understand what you want to achieve but what i'm not understanding is the use case. Is the user form on a separate page from the parametric search form ?
You say it depends on a value that the user selects in the user form. We have hooks that we can use to get that value they select and redirect to the form with that value in the URL.
I just need to know the page that the user form is on and the page that the search form is on and the field that will be setting the value in the URL.
