How do get link to question/answer/comment from within filter module?

Question

I cannot see any possibility how to get the link to the recent question (answer/comment) from the filter module.

I tried $question['postid'] but this gives me an undefined index.

Is there any way I can get the link to Q/A/C or at least the postid?

----

I ended up using the event module and catching the q_post, a_post, c_post events which have the postid in the $params['postid'].

Unless you're editing an existing post, the filter module is called before the post is created, so it does not yet have a postid. If you want to do something after the post is created, I recommend trying an event module.

Oh wow! So here I was wrong :S. I thought filter is to update the content in post not pre. :(

FYI: If an answer is posted, use function filter_answer() which has $question. Then you can use $question['postid'] to access the question, i.e. the parent of the answer.

I believe filter module is for filtering the stored data and another which is not an event or action. So I think you can update or filter the data rather than sorting.

This is something similar to Wordpress add_filter () This is what I know. So I don't think so this will work to get recent question. But if not then please update my knowledge I would appreciate.

What exactly you are trying to get? May be possible with different approach!

Thanks for your answer. I am filtering formatting and other stuff. Furthermore I implemented if i get mentioned in the post with "@echteinfachtv" it sends me an notification email. Problem is that I would like to have a link there, not only the text. I needed to search for the post each time...

So you want to link @mention to the question/answer/comment? Or to the user profile? Sorry just confused because usually @mention linked to the user profile or somewhere.

Linking to the Q/A/C where the mention is. The user profile is not necessary, that would be easy ;)

But to make it clear, when @echteinfachtv appears in text, the filter module is sending an email with this text to my email address. Then in this mail, I'd like to have a link that points to the post.
