#10073 closed Bug (fixed)

ACF should clean up empty elements

Description (last modified by Piotrek Koszuliński)


  1. Create editor without image button (e.g. use one of editors in filter sample).
  2. Switch to source.
  3. Set: <p><em><img src="" alt=""></em></p>.
  4. Switch to wysiwyg mode.
  5. Check with dev tools that editable contains <p><em></em></p>.

There are few cases:

  • <b><img></b>: after filtering out <img> entire <b> should be removed, because it's in DTD.$removeEmpty.
  • <a href=""><img></a> is a different case because it's similar to <a name=""><img></a> and <a name=""></a> shouldn't be removed. So it's an exception, because 'a' isn't included in $removeEmpty. However, why doesn't data processor fix this case? It fixes the case I described in the next point, but why not this? Especially, that I see a filter's rule for htmlFilter that fixes this on output. I think that identical rule should exist for toHtml(). And perhaps previous point should also be handled by data processor...
  • <p><img></p>}: after filtering out <img> filter will left empty <p></p> which then will be correctly handled by data processor, so in this case we don't have to act.

Another uncool case - when table is allowed (e.g. by style), but tr,td are not, then table is incorrectly stripped out.
