How to create the rewrite rule for the url where the parameter/arguments will contain the dynamic value?

Question

I have a rwrite rule which is like this:

RewriteRule ^30/edit-print-ready-vinyl-banners.html edit_print_ready_form.php?id=30

Now I need a Rewrite rule such that if i append the dynamic parameter say "pro_id" and "osCsid" to it likewise

edit_print_ready_form.php?id=30&pro_id=51&osCsid=hdsfjhfkjhk11212jhkjkjhkjh

Now if i use the rewrite rule I have mentioned at the top, I do not get the "$_GET['pro_id']" and "$_GET['osCsid']" on the page i am redirected to..

please guide me to write a rewrite rule to have it for dynamic parameters appended to it

Answer 1

Set the QSA flag for that rule to have the original query automatically appended to the new one:

RewriteRule ^30/edit-print-ready-vinyl-banners.html edit_print_ready_form.php?id=30 [QSA]
