Mod-Rewrite: Ignore/exclude parameter when using QSA flag

Question

I'm trying to pass parameters and use the GET function in PHP on a URL that has already been rewritten using mod rewrite, this is a follow on question from PHP: GET Variables on Mod Rewritten URL .

This is what I have at present:

RewriteRule ^search/$  ?action=search [L,QSA]

I would like the URL to only show as search/?q=test&p=1 instead of search/?action=search&q=test&p=1 which is what the above rewrite rule gives me, is there a way to tell it to ignore the first parameter on the rule or to ignore a specific parameter?

RewriteRule ^search/?q=([^/]+)&p=([0-9])$ ?action=search&q=$1&p=$2 [L,QSA]

Answer 1

You can use the following rule with %{THE_REQUEST} variable to match against the full request line:

RewriteCond %{THE_REQUEST} /search/\?action=[^&]+q=([^&]+)&p=([^&\s]+)$ [NC]
RewriteRule ^ /search/?q=%1&p=%2 [NC,L,R]

This will redirect

• ?action=foo&q=bar&p=1

to

• ?q=bar&p=1

And the following rule will then rewrite :

• ?q=bar&p=1

to its orignal location

• ?action=foo&q=bar&p=1

  RewriteRule ^search/$ ?action=search [L,QSA]
