How to remove journal from verbose cite?

Question

I want to remove the journal title and the issue (the yellow part in the screenshot) from the footnote of a citation. The repeating entries can remain as they are. But in the bibliography I still want this information. How can I add different way of using for citations and bibliography? The type of the entry is article.

The bibliography shall stay as it is:

My MWE:

\documentclass[ngerman]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[backend=biber,
style=ext-verbose-ibid,
isbn=false, url=false, doi=false, eprint=false,
dashed=false,
]{biblatex}

\addbibresource{biblatex-examples.bib}

\begin{document}
    Lorem\autocite{aksin} %article
    ipsum\autocite{angenendt} %article
    dolor\autocite{aksin}
    \printbibliography
\end{document}

What do you want to happen to other entry types like @book, @incollection etc.? I outlined general principles to modify verbose citation styles just this morning, maybe that helps a bit: https://tex.stackexchange.com/q/542604/35864 — moewe, May 07 '20 at 20:33
Maybe it helps to ask the question from a different point of view: Not 'what date do you want to remove', but rather 'what data do you want to see in citations?' It would also help if you could explain what you want to see on subsequent (non-"ibid.") citations. — moewe, May 07 '20 at 20:36
As explained in my answer to the linked question, the first citations in a verbose style use the bibliography driver, so in principle they produce the same output as the bibliography entry. If this is not desired then there are several possible ways around this. But which way is the most promising depends on what you want to happen to other types of entries: If you want to see only author, title and date for all entries then that would be done differently than if you want all other entries to remain as is. — moewe, May 08 '20 at 12:26
Since every entry type is a little bit different, I only want to change the way for articles. — Björn Bause-Engel, May 08 '20 at 12:45

I explained the general structure of verbose citation styles and approaches to modifying their output just recently in Customize verbose citation style, so I won't go through the details here again.

The first citation of a work is printed by the bibmacro cite:full (verbose.cbx, ll. 93-99 v3.14). Essentially that macro just calls the bib driver for the correct entry type. This means that the first citation will look almost exactly like the corresponding entry in the bibliography.

If you want to change that for all entry types, you would just redefine cite:full to print something else instead. But if you want to change the output only for @articles, you need a more sophisticated approach. One way is to define a new bibmacro cite:full:article for @articles that prints only the desired data. We would then tell cite:full to use cite:full:article instead of the driver for @article entries.

\documentclass[ngerman]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[backend=biber,
  style=ext-verbose-ibid,
  isbn=false, url=false, doi=false, eprint=false,
  dashed=false,
]{biblatex}

\renewbibmacro*{cite:full}{%
  \usebibmacro{cite:full:citepages}%
  \printtext[bibhypertarget]{%
    \ifbibmacroundef{cite:full:\strfield{entrytype}}
      {\usedriver
         {\DeclareNameAlias{sortname}{default}}
         {\thefield{entrytype}}}
      {\usebibmacro*{cite:full:\strfield{entrytype}}}}%
  \usebibmacro{shorthandintro}}

\newbibmacro{cite:full:article}{%
  \usebibmacro{author/translator+others}%
  \setunit{\printdelim{nametitledelim}}\newblock
  \usebibmacro{title}%
  \setunit{\addspace}%
  \usebibmacro{issue+date}%
  \usebibmacro{note+pages}%
}

\addbibresource{biblatex-examples.bib}

\begin{document}
  Lorem\autocite{aksin} %article
  ipsum\autocite{angenendt} %article
  dolor\autocite{aksin}
  sit\autocite{worman}
  amet\autocite{nussbaum}
  consectur\autocite{sigfridsson}
  \printbibliography
\end{document}

As discussed in the comments, this changes only first citations of @article entries. Subsequent citations and entry types other than @article are unaffected. But the scheme can easily be extended to modify the first citations of other entry types. Just define the bibmacro cite:full:<type> analogous to cite:full:article above.

One additional question, how do I change given name and familiy name? After the declaration I have the two lines \DeclareNameAlias{sortname}{family-given} \DeclareNameAlias{default}{given-family} but they don't work anymore for articles. — Björn Bause-Engel, May 08 '20 at 17:23
@BjörnEngel The name format in cite:full:article obeys the same settings as the bibliography. In this case \DeclareNameAlias{sortname}{family-given} means that you get "Sigfridsson, Emma and Ryde, Ulf". If you want more consistency with other cite:full results you can add \begingroup\DeclareNameAlias{sortname}{default} at the beginning of \newbibmacro{cite:full:article}{% and \endgroup at the end. — moewe, May 08 '20 at 17:27
