使用 .htaccess 重写 URL

Question

I am trying to convert urls like this http://example.com/page.php?user=x&post=x into http://example.com/blogs/user/post

This is the code I have so far, not sure if I'm missing something or have done something wrong as it haven't been successful so far.

RewriteEngine On
RewriteRule ^blogs/([a-z0-9\-]+)/([0-9]{1,11})/$ page.php?user=$1&post=$2 [L]

EDIT: After making some amendments, it returns now an error 404 error saying page.php is not found. I know for certain the file is there.

2ND EDIT: Resolved 404 issue.

The post parameter is optional as well.
user can will have a mix of A-z0-9 (no character limit)
post can only be 0-9 with and upto 11 characters in length

Answer 1

According to http://htaccess.madewithlove.be/ , this should work:

RewriteEngine On
RewriteRule ^blogs/([a-z0-9-]+)/([0-9]+)$ /page.php?user=$1&post=$2 [L]

This transforms http://example.com/blogs/abc_123/67890 to http://example.com/page.php?user=abc_123&post=67890 .

The most notable change is that you apparently can't have a leading / in the first component of the rule, but I also removed the {11} constraint on the post ID since it's unlikely that would have the intended effect.

Try

RewriteRule ^blogs/?([a-z0-9]*)?/?$ page.php?user=$1&post=$2 [NC,L]

The ? indicates that the matching is optional. Therefore for /? the slash is optional.

And for the second section after the ^blogs/?

 ([a-z0-9]*)?

If you remove the ? and * from the above to become like this :

RewriteRule ^blogs/?([a-z0-9])/?$ page.php?user=$1&post=$2 [NC,L]

The user will no longer become optional and must be fully matched. Example http://blogs/John ; If you put + in place of * like below:

RewriteRule ^blogs/?([a-z0-9]+)/?$ page.php?user=$1&post=$2 [NC,L]

The user need to be matched with at least 1 character. For example : http://blogs/J

And if you put * asterisk like below:

RewriteRule ^blogs/?([a-z0-9]*)/?$ page.php?user=$1&post=$2 [NC,L]

It can match to zero length. For example : http://blogs/ . Almost like optional.

If the match failed you will get the 404 Not found error

Answer 3

This code provides the desired results...

RewriteRule ^blogs/([a-z0-9]+)?/?$ page.php?user=$1 [NC,L]
RewriteRule ^blogs/([a-z0-9]+)?/?([0-9]+)?/?$ page.php?user=$1&post=$2 [NC,L]

I also amended the post ID constraint as Fraxtil pointed out.
