Submission validity

• This is not a personal support request, that should be posted on discussions community.
• I checked current issues and this request isn't a duplicate of an existing issue, opened or closed.

Summary

• some plugins use custom url table columns, e.g. user column to save the YOURLS_USER, who created the shortlink
• it is already possible to:
  1. adjust database scheme in plugin activation hook
  2. add new column to the search and order by dropdowns with 'html_select'
  3. apply the custom column for the search/ordering with 'admin_view_search_in' and 'admin_view_sort_by'
• however, handling the changes to the sql query and the generation of long names requires changing code of the core in two places:
  1. admin/index.php::"// Searching": requires modification to add the custom column for the 'search all' case
  2. includes/Views/AdminParams.php::get_param_long_name": currently only works for the native columns without checking for unknown columns

Motivation

• the usage of custom url table columns is made easier without having to patch core functionalities

Describe the solution

1. admin/index.php::"// Searching": add filter to be able to change sql search clause from within a plugin (analogous to where clause with hook 'admin_list_where')
2. includes/Views/AdminParams.php::get_param_long_name": add filter inside the function to allow custom handling (especially for non-native columns)
