I have a form like this:
Code:
<form method="get">
<input type="image" src="button.jpg" name="button" value="1" />
</form>

When you click on the button and submit the form, the resultant url is:
Code:
/mypage.php?button=1&button.x=3&button.y=4

I want to use htaccess to remove the co-ordinates from the querystring to leave:
Code:
/mypage.php?button=1

Can anybody help?

Thanks.

Code:
Options +FollowSymLinks
RewriteEngine On
RewriteBase /

RewriteCond %{THE_REQUEST} ^GET\ /mypage\.php.*\ HTTP/ [NC]
RewriteCond %{QUERY_STRING} button\. [NC]
RewriteRule ^mypage\.php$ /mypage.php? [C]
RewriteRule .* /mypage.php?button=1 [R,L]

Thank you for your reply. I don't quite understand it, but from the looks of it, button=1 is hard coded. I was hoping to retain the value of whatever button was set to in the querystring (and any other querystring variables). So rather than simply replacing the entire querystring with button=1, I want to remove the button.x and button.y part and leave the rest as it is.

In fact, this would be more useful if it worked on any url too (not just mypage.php).

Sorry if I wasn't very clear or have mis-understood your solution.

maniac, your clarification was close to perfect, very nice.. so here is some working code that I think does everything you want.

Code:
Options +FollowSymLinks
RewriteEngine On
RewriteBase /

RewriteCond %{THE_REQUEST} ^GET\ /.*\ HTTP/ [NC]
RewriteCond %{QUERY_STRING} button\.(x|y) [NC]
RewriteCond %{QUERY_STRING} (.*)(button\.[xy]{1}=[0-9]+.?button\.[xy]{1}=[0-9]+.?)(.*) [NC]
RewriteRule .* %{REQUEST_URI}?%1%3 [R,L]

Awesome!

This looks great. And it even makes sense to me!

Cheers mod_rewrite - you're my hero...
