Skipping the edit button in a comment

Arturo G.

Hello to everybody!
I'm working on an add-on which needs to eliminate the possibility of editing your own comments if they contain some given strings in the body (except for administrators as usual).

I have already added a funtion to the DiscussionForm-PostLoadData delagation to prevent editing when the blocking condition is true. It adds a warning and sets FatalError to 1, and it works.

But now, I think it would be nice to eliminate the "edit" button for those selected comments. I have done a dirty trick: I have added a function to the CommentGrid-PreCommentOptionRender delegation which tests the condition and, if it is true, it changes the AuthorID to -1. This produces a fail in the permissions check and the edit button dissapears.

Question: Is there a cleaner way to achieve this?

I havn't look at it but if there no other way, you can extend the class and rewrite the function. http://lussumo.com/docs/doku.php?id=vanilla:development:objectfactory

The problem is that this delegation and the code that includes the 'edit' button are in the comments.php file of the default theme (included from the CommentGrid class).

If I would rewrite the class I would need to include the content of the whole comments.php file into my code to make the small change, wouldn't I?

Yep, and if you extend the render fonction (and so "comments.php"), you will break themes that have a custom "comments.php".

If you need to change something in a template and that a new delegation can't help... well... you still can add a new comments.php to put in the theme folder of the user.

It doesn't sound nice.

I think I will keep with the dirty trick. As far as I know changing the AuthorID in the comment data during the PreCommentOptionRender delegation does not have side effects. In the worst case, if something arises, I could restore the original value in the PostCommentOptionRender delegation.

Thanks!
