How to replace request param name using .htaccess?

@raven_corwin 

To replace a request param name using .htaccess, you can use the RewriteCond and RewriteRule directives to rewrite the URL and change the parameter name. Here's an example:

1
2
3

RewriteEngine On
RewriteCond %{QUERY_STRING} ^(.*)&oldparam=(.*)$
RewriteRule ^(.*)$ $1?newparam=%2 [L]

In this example, we are checking if the query string contains the parameter "oldparam" and capturing its value. Then we are rewriting the URL to replace "oldparam" with "newparam".

Make sure to adjust the parameter names and values according to your specific requirements.

This code snippet will work for simple cases where you want to replace a specific request parameter in the URL. However, if you need a more general solution that works for arbitrary parameter names and values in the query string, you can use the following code:

1
2
3
4
5
6
7

RewriteEngine On

# Match any query parameter name and value pair
RewriteCond %{QUERY_STRING} ^(.+?&)?([^&=]+)=([^&]+)(&.*)?$

# Rewrite the URL by replacing the parameter name with a new name
RewriteRule ^(.*)$ $1?%1newparam=%3%4 [L]

With this code, any parameter name and value pair in the query string will be replaced with the new parameter name specified in the rule (in this case, "newparam"). This provides a more flexible solution that can be used to replace any parameter in the query string.

Remember to test this code on a development environment before applying it to a production server to ensure it works as expected for your specific use case.
