Apache url rewriting and loop

setting url rewriting to have nice urls, i have existing urls like that :
/xxx/test.php

but in the background, it is allways going to the same script with a query :
/xxx/index.php?id=test

with the following rewrite :

RewriteRule ^xxx/([0-9a-z-]*).php$ /xxx/index.php?id=$1 [QSA,L]

it’s working fine.

now, there are old urls still like /xxx/index.php?id=$1
and i want to get rid of these old urls, meaning I want all of them to be for the users like /xxx/test.php with a 301 redirect

i did a rewrite for this but then i’m entering a loop despite the L flag 

RewriteCond %{QUERY_STRING} ^id=(.*)$ 
RewriteRule ^xxx/index.php$ /xxx/%1.php? [R=301,L]

? is it possible to handle that and how ?

and other to describe it is allways use the script :
/xxx/index.php?id=$1
but allways have the right url in the browser displayed

    Make your RewriteRule not match index.php or remove the QSA flag.

    Say you type test.php well now you will go to index.php?id=test

    Then Rewrite occurs again and you will go to index.php?id=index&id=test

    Then it will occur again because the page is different: index.php?id=index&id=index&id=test etc.

    So add in your regex a negative lookahead: xxx/(?!index)([0-9a-z-]*).php

    Try:

    RewriteRule ^xxx/(?!index)([0-9a-z-]*).php$ /xxx/index.php?id=$1 [QSA,L]

    Keep your existing

    RewriteRule ^xxx/([0-9a-z-]*).php$ /xxx/index.php?id=$1 [QSA,L]

    which appears to work fine.

    Add in these two lines before that which will catch if there is an id= and strip it out of the URL.

    RewriteCond %{QUERY_STRING} ^id=([^&]*)(.*)$
RewriteRule ^xxx/([0-9a-z-]*).php$ /xxx/index.php?id=%1%2 [L,R=301]
    • ^ start of query string
    • ([^&])* any character except &
    • (.*) any following characters

    So if query string is id=test&something=else RewriteRule will append exactly that and nothing else as there is no more QSA flag.

    Try those 3 lines together (htaccess test website), here is the full htaccess file:

    RewriteCond %{QUERY_STRING} ^id=([^&]*)(.*)$
RewriteRule ^xxx/([0-9a-z-]*).php$ /xxx/index.php?id=%1%2 [L]

RewriteRule ^xxx/([0-9a-z-]*).php$ /xxx/index.php?id=$1 [QSA,L]
