#1660 closed defect (bug) (fixed)

bp_create_excerpt can split html tags

Reported by: junsuijin's profile junsuijin Owned by: junsuijin's profile junsuijin
Milestone: 1.2 Priority: major
Severity: Version:
Component: Keywords: has-patch, needs testing


Because exploding content with a space delimiter can split html tags like 'a' or 'img' and cut them at the 55 word-limit, creating ugly half-codes at the end of excerpts, a preg_split should be used to count <a...</a>, <img ... >, <object...</object> and other inline elements like span etc as single words. I have tested this code extensively for trimming unstripped blog post excerpts but have not tested with BuddyPress specifically. Decisions can also be made as to whether to even allow <object>s into the excerpts (I haven't looked but perhaps these tags get removed at some other point). This code does not handle iframes. If desired I can use an 'x' flag on the regex and attempt to make it more readable.

Object tags are handled before this. Could you update the patch to remove the object support? Thanks.

bp_create_excerpt.2.patch is updated to remove object support.

A short explanation of the regex pattern:
it splits the string on <tag ...>[optional non-space chars]. It also splits on the space character(s), similar to what the normal explode would do. If it splits on a <tag> with or without a word attached after it (<opening tag>word as explained above), it captures that delimiter, discarding the surrounding space characters and adding it as another word in the array. I have tested this regex extensively on unstripped WordPress post excerpts and it has to be formatted in this order to function properly. The force_balance_tags function must also be used (it is currently added to the bp_create_excerpt filter), because the word limit might be hit after <opening tag>word another-word...before the closing tag occurs.
