You can append the values in the query string for the next page to see and process. You can wrap them inside the link tags:
<a href="your_page.php?var1=value1&var2=value2">
You separate each of those values with the &
sign.
Or you can create this on a button click like this:
<input type="button" onclick="document.location.href = 'your_page.php?var1=value1&var2=value2';">
