Can´t get a comma after the title in Biblatex with IEEE style and online typ?

Question

I am writing my master thesis and started to work with biblatex. It is definitely easier than bibtex. I discovered that there is a special online type for websites and I wanted to use it, because I use quite some websites.

I want to list the websites in the following style:

Author, "Title", note, (date), URL, (URLdate)

Because of this I use the IEEE style and change it when there is a dot, but I can´t get a comma after the author and after the website.

I only get the following:

Wich is

Author. "Title". note, (date), URL, (URLdate)

I tried to add the comma with the following, but this doesn´t work.

\DeclareFieldFormat[online]{tile}{\enquote{#1}\addcomma}
\DeclareFieldFormat[online]{author}{#1\addcomma}

Till now I used the type misc for websites, thats why i included it in my example code

\usepackage[T1]{fontenc}

\DeclareFieldFormat[online]{note}{#1\addcomma}
\DeclareFieldFormat[misc]{date}{(#1)\addcomma}
\renewcommand*{\finentrypunct}{}
\DeclareFieldFormat[online]{tile}{\enquote{#1}\addcomma}%does not work
\DeclareFieldFormat[online]{author}{#1\addcomma}%does not work

Instead of adjusting the field formats, it is easier and cleaner to change the driver: (Some styles use commands for the punctuation which can be adapted, but yours not).

\DeclareBibliographyDriver{online}{%
  \usebibmacro{bibindex}%
  \usebibmacro{begentry}%
  \usebibmacro{author/editor+others/translator+others}%
  \setunit{\addcomma\addspace}% <--- comma
  \usebibmacro{title}%
  \setunit{\addcomma\addspace}% <--- comma
  \printlist{language}%
  \setunit{\adddot\addspace}%
  \usebibmacro{byauthor}%
  \setunit{\adddot\addspace}%
  \usebibmacro{byeditor+others}%
  \setunit{\adddot\addspace}%
  \printfield{version}%
  \setunit{\adddot\addspace}%
  \printfield{note}%
  \setunit{\addcomma\addspace}% <-- comma ?
  \printlist{organization}%
  \setunit{\adddot\addspace}%
  \iftoggle{bbx:eprint}
    {\usebibmacro{eprint}}
    {}%
  \setunit{\adddot\addspace}%
  \printtext[parens]{\usebibmacro{date}}%
  \newunit\newblock
  \usebibmacro{url+urldate}%
  \setunit{\adddot\addspace}%
  \usebibmacro{addendum+pubstate}%
  \setunit{\bibpagerefpunct}\newblock
  \usebibmacro{pageref}%
  \newunit\newblock
  \iftoggle{bbx:related}
    {\usebibmacro{related:init}%
     \usebibmacro{related}}
    {}%
  \usebibmacro{finentry}}

You can use the xpatch package to patch the bibliography driver for online entries. For use inside biblatex macros you should use \mkbibquote instead of the csquotes command \enquote.
