How to do a javascript redirect and include post data

Question

I am designing an web application. This application has a number of users.

All users can see and use a search form - however only those who are logged in can submit the form properly.

So when the form is submitted - BEFORE redirecting to the results page and showing the results, a jquery ajax function fires, checks if the user is logged in and if the user is logged in does a window.location.replace('searchresults.php') to the search results page.

How can I ensure that the correct POST data (from the form input fields) is included in the redirect?

Answer 1

Create hidden form and submit it via javascript instead of window.location.replace('searchresults.php')
