RewriteEngine on
RewriteBase / 
RewriteRule ^.*code=1.*$ /post/path/ [L]

[REQUEST_URI] => /post/path/?code=1/oWTYGaoOsyts
[SCRIPT_NAME] => /index.php
[PHP_SELF] => /index.php

Answer 1

For searching a parameter in the URL, you need to use RewriteCond and %{QUERY_STRING}:

RewriteCond %{QUERY_STRING} ^.*code=1.*$
RewriteRule .* /post/path/ [L]

From the documentation :

Syntax: RewriteRule Pattern Substitution [flags]

In Directory and htaccess context, the Pattern will initially be matched against the filesystem path, after removing the prefix that led the server to the current RewriteRule (eg "app1/index.html" or "index.html" depending on where the directives are defined).

If you wish to match against the hostname, port, or query string, use a RewriteCond with the %{HTTP_HOST}, %{SERVER_PORT}, or %{QUERY_STRING} variables respectively.

Answer 2

Because you're searching for code=1 and you pass code=4

This should work with given input

RewriteRule ^.*code=4.*$ /post/path/ [L]

Note that it can match unintended urls like code=40 or somecode=4
