Question

I have an external app that generates html which I publish via a twiki site.The html is included into a TWiki page using:

%-INCLUDE{"%-ATTACHURL%/uidlist.html" raw="on" literal="on"}%

The html contains lots of tables and I want to allow users to comment on the table entries without changing the html itself.

I am trying to add a button to each table which when clicked will either create a new twiki topic into which user comments can be added, or if the topic has already been created, then just append comments.

I can sort of get what I want by using a form within the table:

<-form name="comment" class="buttonstyle" action="%-SCRIPTURLPATH{edit}%/%-WEB%/">
 <-input type="hidden" name="action" value="text" />
 <-input type="hidden" name="id" value="UID100" />
 <-input type="hidden" name="topic" value="projectUID100Comments" />
 <-input type="hidden" name="templatetopic" value="projectUIDCommentTemplate" />
 <-input type="hidden" name="topicparent" value="-%TOPIC%" />
 <-input type="hidden" name="onlywikiname" value="on" />
 <-input type="hidden" name="onlynewtopic" value="on" />
 <-input type="submit" class="twikiSubmit" value="Add Comment" /> 
<-/form>

But whenever the button is clicked it always creates a new topic which overwrites any existing topic of the same name (as created by a previous user clicking the Add Comment button).I have played around with the "onlynewtopic" parameter, but it does not seem to change the outcome.

Is what I wish to do possible? If so, please can you direct me how (or where to go look).

Thanks.

Note, I tried replacing the word edit with

%IF{"istopic 'projectUID100Comments'" then="view" else="edit"}

but that ended up generating bad html:

<form name="comment" class="buttonstyle" action="%-SCRIPTURLPATH{view/Sandbox/"> 

It almost worked though!

I also tried removing the literal="on" from the include line, but this actualy made things worse (rather than better as I had expected).

Use a custome CommentPlugin template. See sample applications in the Sandbox web, such as EditActionItems and GenericVote.
