keep params and add another from a form
- by doubtful
Hey Guys,
I have the following 3 urls:
http://www.test.com?a=1
http://www.test.com?a=1&b=3
http://www.test.com?a=1&b=2&c=99
Now in a form i have a drop down menu like so:
<select name="b">
<option value="1">1</option>
...
</select>
Now i want to either add that param to the list of existing params or edit the param if its already there, then refresh the page.
Any ideas?
Thanks
