Extension: Scroll to Comment
Development and Programming
I’ve just started working with ExpressionEngine (first site hopefully launching tomorrow), and one thing I found sorely missing was the ability to make a page scroll down to the newly submitted comment after a visitor has added it.
So I made an extension. And here it is. 😊
It’s pretty basic - stick the extension file in your /extensions folder and the language file in your /languages folder, and enable the new extension under Admin > Utilities > Extensions Manager.
The single setting allows you to specify a prefix for the comment_id to be used in the markup. (Under a Strict doctype, you can’t start a CSS id with a number, so you should really call them “comment123” or similar).
Any feedback, suggestions or comments, please let me know. 😊

Fantastic work, thanks for this one. Going to try this out later.
Perhaps this thread should be re-titled and moved to the Extensions development forum though? 😉
Best wishes,

Hi,
I made a little fork of Scroll to Comment extension. The aim of this fork is to have a a possibility to form URLs without # symbol. That is, instead of forming URLs as this
http://mysite.com/index.php/blog/entry/#comment190
to form them as this
[quote]http://mysite.com/index.php/blog/entry/comment190/
Such possibility can be handy in some cases (e.g. when there are on the page elements having CSS “position” set to “fixed” or in cases when javascript onload makes some change of CSS rules, such as change of font). In these cases URLs having # symbol cannot scroll marked element into view correctly; only some custom javascript that parses URL can.
In settings I added a new option “Use symbol # in the last URL segment” (default is yes). And in ext.scroll_to_comment.php file I added all needed branching of code for the case “yes” and for the case “no”.
Hi,
I published Comment Location plugin which can be used together with Scroll to Comment extension in order to support pagination of comments.
Good stuff. 😊 Sorry for not replying to your emails about forking, I’ve been too snowed under with ‘proper’ work to worry about EE add-ons. 😉
Matthew,
This extension does not play nice with Weever. Might there be a simple solution to solve the conflict?
(If both are installed, weever no longer nests new comments. Old comments are not affected however; they are still displayed in the proper, nested order.)
The conflict seems to have something to with the fact that both extensions use the insert_comment_end hook. Weever has priority 10, scroll-to-comment priority 1.
I’ll take a look when I have time. Your last comment seems to indicate that either:
- Weever isn’t checking whether previous extensions have modified the session, or
- I’ve stopped all processing of further extensions after Scroll_to_comment runs
Looking at my code it may be that the latter is true. Try removing the $EXT->end_script = TRUE line from my extension.
Thanks Matthew. I really appreciate it.
I tried removing the $EXT->end_script = TRUE line, but that didn’t work.
In case it helps, Mr. Wilson, the author of Weever, sent me to this page in the docs for a clue as to what might be the problem: http://expressionengine.com/docs/development/extensions.html#hook
