htaccess基于查询字符串的网址

Question

Suppose my website is www.example.com

Earlier the urls of my website was like this www.example.com/php/bookdetails.php?bid=33

Last week i changed the urls of my site to this www.example.com/bookdetails/33

and wrote an htacces like this

RewriteRule ^bookdetails/(.*)$ php/bookSearchResult.php?bid=$1

The problem is that there are some external site using my earlier URL structure ( www.example.com/php/bookdetails.php?bid=33 ) and what i want is to redirect it to my new URL structure ( www.example.com/bookdetails/33 ).

I know it can be possible in htaccess, but i have no idea how to do it

Answer 1

RewriteRule ^php/bookdetails\\.php\\?bid=(\\d+)$ bookdetails/$1 [L,R=301]

A PCRE to match the old format, capturing the number, the new URL with the reference to the captured number, Last rule, Redirect with HTTP status 301 (moved permanently)

( Tested it for syntax, but not to ensure that it works exactly . I'm fairly sure that if this isn't it, it should be close.)

Make sure this rule is before the other you mentioned rewriting to the proper php URL, or you'll get a 500 for an infinitely looping rewrite.

The Rewrite Guide and the Advanced Rewrite Guide are invaluable resources for examples.

EDIT:

BTW, this is a duplicate of .htaccess and seo friendly urls , and probably several others, for additional ideas. (I should have looked for a dup first.)
