RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]*)/?$ page3.php?cat=$1 [L,NE,QSA,NC]

Answer 1

As Panama Jack stated, the server cannot simply guess which rewrite needs to occur after the page has been redirected, simply because the patterns for each of your three rules are exactly the same . As such, the first rule will always execute, and nothing else will.

To tackle this, use the following code instead:

RewriteEngine on

RewriteBase /bookshow/

# Step 1: Redirect all pagex.php?... to new URIs

RewriteCond %{QUERY_STRING} cat=([^\s&]+)$ [NC]
RewriteRule ^page1.php$ cat/%1? [R=302,NE,L]

RewriteCond %{QUERY_STRING} name=([^\s&]+)$ [NC]
RewriteRule ^page2.php$ name/%1? [R=302,NE,L]

RewriteCond %{QUERY_STRING} id=([^\s&]+)$ [NC]
RewriteRule ^page3.php$ id/%1? [R=302,NE,L]

# Step 2: Rewrite cat/something, name/something, id/something to the actual pages

RewriteRule ^cat/([^/]*)/?$ page1.php?cat=$1&r [L,NE,QSA,NC]
RewriteRule ^name/([^/]*)/?$ page2.php?name=$1&r [L,NE,QSA,NC]
RewriteRule ^id/([^/]*)/?$ page3.php?id=$1&r [L,NE,QSA,NC]

Further Explanation:

In the first step , we're checking which page is being access with what query string. If there is a match, redirect to the new URI.

For example, page1.php?cat=hello will redirect to cat/hello .

Then, in the second step, we rewrite these new URIs to the already-existing pages, and append &r to the query string so we avoid a redirect loop. This &r is basically redundant, and acts like a dummy.

For example, cat/hello will internally rewrite to page1.php?cat=hello&r .

Updated: I have removed RewriteCond %{REQUEST_FILENAME} !-f and RewriteCond %{REQUEST_FILENAME} !-d from the code as well - these are not needed. Feel free to put them back if you ever land up needing them.
