Question

Twiki in preview mode does not allow to click on links (only after page is saved) which makes sense. But CommentPlugin does not, and if accidentally you click on "Add commnent" button in preview mode, your edited changes are lost, and obviously no comments are added.

I know I should switch to a skin without preview and I might. But I want to fix this bug. How to detect in plugin that I am in preview mode? In preview, I might even return '' and do not render COMMENTS at all - it is fine too

• TWiki version:
• Perl version:
• Web server & version:
• Server OS:
• Web browser & version:
• Client OS:

Answer

There is currently no API to check for that.

A (possibly not so portable) way is to check for the SCRIPT_NAME env variable, which is for example /cgi-bin/preview.cgi.

Thank you. If it will work for me, it's portable enough . Another portable way could be to use skin without preview and CgiSaveMulti

It's worth noting that this is a general "problem" with forms in TWiki content - whilst user inserted links are redirected user inserted forms are not. Personally I find this useful - it makes it easier to test that the form is right (hence the quotes around problem )

The comment plugin is one aspect of a form embedded in the page. Another is where you have a form designed for creating pages - eg applications using TWiki, using TWikiForms, using URLPARAM based variables to populate pages etc. Eg a bug report form, a to do list etc.

Why does it make sense to disable the links in Preview mode? Here's a user case in which I'd prefer the links were there: in a TWiki page with headings, I want to obtain the anchor URL pointing to a heading long enough that not all the words will be included in the anchor part of the URL. To know what URL TWiki generates for that header, I'd edit the page, add %TOC% at the beginning, then copy/paste the URL of the heading. If links are disabled, I can't do that.
