QUESTION:

What does error_article_context mean?
What does error_comment_context mean?



ANSWER:

Certain Textpattern tags are only intended for use in a particular context.

Article form tags work only in an article context. They refer to a single article, so they can only be used in a context that identifies one particular article. Specifically, they may be used on an individual article page template, or in an article form that has been displayed using a <txp:article ... /> or <txp:article_custom ... /> tag.

Article context tags will not work in an article list page template, because list pages are not associated with any single article.

Comment form tags may only be used in the form that is used to display each individual comment (usually named comments).
