hyphen on custom field names + article_custom
Hi.
As you may know, a custom field name can be used as an attribute for txp:article_custom
Doing that, the output will be restricted to only articles that have that custom field filled with some particular value.
For example (being “featured” the name of a custom field):
<txp:article_custom featured="yes" />
It will list just those articles that have “yes” as the value for the custom field “featured”.
Now, the problem: if the custom field name has an hyphen, then the filtering doesn’t work.
For example (being “featured-article” the name of a custom field):
<txp:article_custom featured-article="yes" />
That won’t work (at least, on a 4.0.6 installation) :(
The workaround: use an underscore (“featured_article” and <txp:article_custom featured_article="yes" />) and it will work.
Can anyone confirm if this is a bug/issue or if hyphen are prohibited in custom field names?

Custom names may include letters (uppercase or lowercase), numbers and under_scores, but no spaces or other special characters. [From Textbook BTW: I find an underscore a more special character than a hyphen.

Thanks for clarifying, uli. I should have taken a look at the textbook.

Re: hyphen on custom field names + article_custom
FYI, it is a PHP limitation.
