Appending query string params dynamically

Question

I have a webpage which allows users to filter results. Once a filter is set it is appended to the URL eg: www.testsite.com?show=active. The results are broken into several pages (simple pagination) once a user clicks a certain page the page is also appended to the user like www.testsite.com?page=3. The problem I have is that after applying a filter and then clicking a page number the URL should be www.testsite.com?show=active&page=3 but instead the URL turn into just www.testsite.com?page=3 loosing the previously set filter.

I set the href to the pagination links as follows <a href='?page=3'>3</a> and to the filter links as <a href="?show=active">Active items</a>

Any help to resolve this issue is appreciated.

You can use

 $_SERVER['QUERY_STRING']

To get the current query string

You can prepend it to your links like

 '?' . <?= $_SERVER['QUERY_STRING']; ?> . '&show=active'
