URL将旧URL重写为新URL

Question

I'm trying to rewrite this:

index.php?action=dlattach;topic=2745.0;attach=14374;image

to this:

attachments/opening-inauguracion-png.14374/

What I've built so far but it isn't working is this:

RewriteRule ^index\.php?=dlattach;topic=([0-9]+);attach=([0-9]+);image /attachments/$2/ [R=301,L]

Answer 1

To manipulate the query string you need to use a rewrite condition with %{QUERY_STRING} :

Options +FollowSymLinks -MultiViews

RewriteEngine On
RewriteBase /

RewriteCond %{QUERY_STRING} attach=([0-9]+) [NC]
# if you need a more exact match of your current query string
# comment the above RewriteCond and uncomment the below RewriteCond
#RewriteCond %{QUERY_STRING} ^action=dlattach;topic=[0-9\.]+;attach=([0-9]+);image$ [NC]
RewriteRule ^index.php$ attachments/opening-inauguracion-png.%1/ [R=302,NC,L]

Also only change it to 301 once you have confirmed the rule is working to avoid caching your browser while testing a rule which can be bad in case the rule is not properly working to mitigate the same.

I think you mean the opposite:

RewriteEngine On
RewriteRule ^attachments/opening-inauguracion-png.([0-9]+)$ /index.php?action=dlattach;topic=2745.0;attach=$1;image [R=301,L]
