问题
I currently have a simple rewrite that redirects
/photos/2
to
/photoviewer.php?photo=2
However I need to be able to allow the user to add a photo to their cart so I was thinking I need to retain the query string so that the following works.
/photos/2?action=purchase
redirects to:
/photoviewer.php?photo=2&action=purcahse
My current htaccess rule is:
RewriteRule ^photos/([a-zA-Z0-9_-]+)$ photoviewer.php?photo=$1 [L]
回答1:
Append the [QSA] flag (query string append).
RewriteRule ^photos/([a-zA-Z0-9_-]+)$ photoviewer.php?photo=$1 [L,QSA]
回答2:
In your rule, replace [L] with [L,QSA].
That will then retain the query information.
Hope this helps!
回答3:
[QSA,L] instead of just [L] should do the trick. Hope this helps!
回答4:
How about just extending the idea to pass "any" name/value pairs thru the URL to the photoviewer.php script? This is an elegant approach I've used in the past.
RewriteRule ^photos\/([^/\.\-]+)\/([^/\.\-]+)$ /photoviewer\.php\?$1=$2 [L]
RewriteRule ^photos\/([^/\.\-]+)\/([^/\.\-]+)\/([^/\.\-]+)\/([^/\.\-]+)$ /photoviewer\.php\?$1=$2&$3=$4 [L]
RewriteRule ^photos\/([^/\.\-]+)\/([^/\.\-]+)\/([^/\.\-]+)\/([^/\.\-]+)\/([^/\.\-]+)\/([^/\.\-]+)$ /photoviewer\.php\?$1=$2&$3=$4&$5=$6 [L]
So, something like:
photos/photo/2/action/purchase
rewrites to:
photoviewer.php?photo=2&action=purchase
