Generating introtext from content

Hi all,
does anyone knows of a way I can set the page [+introtext+] to be the first <p></p> of same page content?

It seems possible using regex and the documentObject[’content’] but it would likely take all day for me a PHP grasshopper to wade through.

Sorry.

Something similar was discussed in a recent post. You want this in intro text to be able to display the summary in Ditto or some other snippet? If so look at this post and see how to do it on the fly with PHx:

Also you could turn that phx modifier into a snippet and just drop that into the intro text field, or maybe even turn it into a plugin and have it run onDocumentSave. That sould like a good idea. Wonder if this already exists? Seems that I have seen something like this in the Repository.

thx for the replies.

are you talking about this from the repo?

edit:
just read the post you linked up there. just what I needed. phx defiently the easiest way to go. still would be nice to have it set on all new docs like that instaed of adding the introtext manually.

are you talking about this from the repo?

No, this is the same as the PHx described. It would work as well for dynamic on the fly descriptions (as the name says). The plugin would actually record the data, not sure if that would really an advantage of any sorts (load wise) but it sounds good

Hm. That does indeed sound good. Would obviate the necessity of training end users to copy the first x amount of text into the Summary field for Ditto’s use.

make sense too isn’t it?
I mean 99% of the time your introtext *should* be your first paragraph if you write properly (I think), I do needed it for Ditto call where I show some products description polled from the introtext. using the [+content+] with phx:word_limit from the wiki can save me the chopped words but still I won’t have all the first paragraph. tuatara posted here something to avoide this and to kepp the whole first <p>. I’ll play with all these and see if I can make it work somehow.

how I wish I knew some php

The trick here would be to get all the text up to the first </p> occurance. I am not sure how to do that with PHx but it is not hard to do with a snippet.

Another issue I can think of if using this is a plugin with OnDocomentSave is with pages like ’login’ and ’search’ where the first <p> can be a snippet and I’ll end up with the snippet call in my introtext.
so maybe not such a great idea after all

The plugin could specifically exclude a list of page IDs, or perhaps even better, since this really would only be useful for blog or news pages, have it work with pages whose parent is in a list of ids.
