query-string-keeper

Query String Keeper plugin for YOURLS - tested on YOURLS version 1.8.3 and php version 8.0.12.

Description

Query String Keeper retains the query string added to the short url and adds it to the long url. If the long URL already includes a query string, it appends it following an ampersand (&) and if not, appends it to the long url following a question mark (?).

Examples

Examples 1 & 2 use the following short & long URLs configured in YOURLS:
Short url = http://sho.rt/keyword
Long url = http://www.longurl.com

Example 1
http://sho.rt/keyword?foo=bar
...becomes...
http://www.longurl.com/?foo=bar

Example 2
http://sho.rt/keyword?123
...becomes...
http://www.longurl.com/?123

Example 3 uses the following short & long URLs configured in YOURLS:
Short url = http://sho.rt/keyword
Long url = http://www.longurl.com?foo=bar
Example 3
http://sho.rt/keyword?zoo=car
...becomes...
http://www.longurl.com/?foo=bar&zoo=car

Installation

1. Move query-string-keeper directory to the /user/plugins directory of the YOURLS installation.
2. Go to the Plugins administration page ( eg http://sho.rt/admin/plugins.php ) and activate the Query String Keeper plugin.

This plugin adapted from the Query String Keeper plugin by jessemaps. Solved the problem <PHP v7 for some reason does not return any value in $_SERVER['QUERY_STRING']>. Thanks for skarjoss's comment.
