Alternative to Backspace Parameter

Question

I asked this question some time back and it worked, however I don't see the backspace parameter listed in the docs now, nor do I see in the change log that it was removed. I tried it anyway and it doesn't work. Is there another way to remove the last comma from a list of tags? Thanks

Answer 1

backspace="" also takes newlines and extra spaces into account. So if you have

{exp:tag:tags backspace="2"}
   {tag_name}, 


{/exp:tag:tags}

...this will remove the last two linebreaks, leaving the last comma intact. Instead try removing these non-printing characters:

{exp:tag:tags backspace="2"}{tag_name}, {/exp:tag:tags}

This can happen not only with Tag, but with other add-on and native EE tags as well.
