I have a few parameters, I have to preserve, like 'order'.
I also have links, where the user can click, to change the order of links.
But if a link already has the parameter 'order', clean_output will also add his own 'order' to preserve it... So there will be duplicate 'order' parameters. Check my example in my original post.
It should check, if there is already an 'order' parameter in the link, then should keep the one from the link, since the parameter in the link must have higher priority, than the one is preserved.
So the 'order' parameter in the link should override, the one we preserved from other page.
Do you see now?
