当前URL添加和删除term-> slug

I have some issues with add/delete taxonomy from url.

$arch_postID - i get posts ID's from loop on current archive page.

How it works:

1 - when i push <a class="cat-hide-link" href="'. $URI .''. $res_slug[$f] .'" >+</a> i'm aditing to page URL appropriate '+slug'

2 - When i push <a href="'. $linkk .'" >-</a> i'm removing appropriate '+slug' from current url( if it's exist )

Now code working like that:

I have 3 slugs to add, "other-1", "other-2", "other-3". I add them one by one, first- "other-1", last- "other-3"

Current URL be like - "domain/other/other-1+other-2+other-3"

When im trying to push "-" on slug "other-1" i get back whole current URL

When im pushing "-" on slug "other-2" i get URL - "domain/other/other-1". But not URL - "domain/other/other-1+other-3"

When im pushng "-" on "other-3" i get right back value. URL - "domain/other/other-1+other-2"

Some one, Help pls! Thanks for your time!
