Using article_custom with attribute month
I detected that
<txp:article_custom section='articles' month='2025-07' />works as documented, but putting the month in a variable
<txp:article_custom section='articles' month="<txp:variable name='d' />" />doesn’t.
What is the official or recommended way to use the month attribute with variable values?
Are there any usage examples available?

Try switching the quotes around. Use single quotes to denote “process the contained tag and puts its result here”, otherwise double quotes for normal attributes.
<txp:article_custom section="articles" month='<txp:variable name="d" />' />And your variable d should take the form YYYY or YYYY-MM. You can use the format attribute to output dates in other formats using strftime notation, e.g. format="%Y-%m" …

Re: Using article_custom with attribute month
Thanks for your prompt reply. I have tested all possible variations before. Out of the box, your proposal didn’t work either.
The problem is/was that I defined the variable formatted using multiple lines.
<txp:variable name="d">
...
</txp:variable>Thus the variable content was surrounded with some whitespace and linefeed (?) chars.
Two solutions:
a) Write the definition as a one-liner; avoid any whitespace.
<txp:variable name="d">...</txp:variable>b) Add a trim attribute on insertion.
<txp:article_custom section="articles" month='<txp:variable name="d" trim="/[\n\r\t ]/" />' />Everything is working as expected now.
Huge thanks!

Hmm, that’s annoying that linebreaks break strtotime(), thanks for the hint. Can anyone see any drawback of incorporating a cleanup into core?

Glad you got it working, and it sounds like you know what you’re doing, and found your solution.

Doesn’t adding trim.during variable definition work?
<txp:variable name="d" trim>
...
</txp:variable><txp:article_custom section="articles" month='<txp:variable name="d" />' />The smd plugin menagerie — for when you need one more gribble of power from Textpattern. Bleeding-edge code available on GitHub.
