[wp-hackers] re-thinking about the way filters work

[David Chait]

Ummm.  Guess that's one way, but maybe there needs to be yet-another filter, the_excerpt_content, or something like that, for the generated exerpt.  Also, realize that some folks like me write plugins that use the "get_zzzz" versions of things, so if you are hooking the_excerpt but not get_the_excerpt, the plugin won't necessarily get a properly-processed excerpt (although in this case, it's probably the correct result... highlighting shouldn't affect 'more direct' retrieval, just the 'generic page output tags'.

  as being discussed at this forum post
  http://wordpress.org/support/topic/37331
  there seems to be a problem in the functioning of 'the_excerpt' & 'the_content' filters. The thing is that if there's no excerpt for a post, 'the_content' is used by 'the_excerpt' to create an excerpt. so far its ok, but the problem is that the excerpt created has the filters applied to it which were for 'the_content' & then the filters meant for 'the_excerpt' are applied. But if there are one or more filters that are same for 'the_content' & 'the_excerpt' (as in my plugin's case, ig:Syntax Hiliter), there comes the problem with the plugin not working correctly on the excerpt.


  Proposed Solution:-
  -----------------------
  The logical way would be that 'the_content' filters are not applied to the excerpt generated by 'the_content' as at that time, 'the_content' is not the target entity but is merely acting as a conduit for 'the_excerpt' to generate an excerpt from the DB. So when 'the_content' & 'the_excerpt' are treated as seperate entities by allowing different filters on each, then why not allow it in the right way? else what's the use of having 'the_excerpt' filter when 'the_content' filter is gonna be applied to the excerpt??
