PHP & Apache Mod rewrite: search?keyword

these are the rewrite rules I normally use for clean urls,

RewriteRule ^([a-zA-Z0-9\-]+)/?$  index.php?pg_url=$1 [L,QSA]
RewriteRule ^([a-zA-Z0-9\-]+)/([a-zA-Z0-9\-]+)/?$  index.php?pg_url=$2开发者_如何学JAVA [L,QSA]

they will accept requested urls such as,

mysite/home
mysite/portfolio/photograhy

but how can I set the rewrite rule for seaching such as,

mysite/search?photograhy
mysite/search?painting

I tried with this one below,

RewriteRule ^search?([a-zA-Z0-9\-]+)/?$ index.php?pg_url=search&keyword=$1[L,QSA]

they keyword seach won't appear correctly, but I will get this below whatever I search for,

echo $_REQUEST['keyword'];


h[L,QSA] // result

thanks.

You need to use a RewriteCond for the Query String, a la:

RewriteCond %{QUERY_STRING} ^keyword=([a-zA-Z0-9\-]+)$

You'll need to adjust your query to do something like ?keyword=photography
