Hook of 'media_send_to_editor' filter causes no output.

[slancio]

I have a site there I'm trying to make modifications to the HTML returned when uploading images in a post via the Add Media button.

Just the act of hooking that filter seems to cause the Add Media button to output no HTML whatsoever . I am passing $html, $send_id, and $attachment to my hook function and returning $html.

Interestingly enough, the body of the function seems to not run. I've tried setting debugger lines within the function, vardump the input variables, even exit(). Nothing seems to happen within the function body, xdebug doesn't kick off within the function body and no output is returned either. Once I remove the hook, everything seems to work fine again.

This happens on a fresh install of 4.7.2 I also tried this on 3 other WordPress site installs that I have in production versions 4.5 and later and experience the same behavior.

Hi @slancio, welcome to Trac! Thanks for the report.

I could not reproduce the issue on a clean install, media_send_to_editor filter works as expected for me.

Could you provide an example code of the function you're using?

[slancio]

I've made it as simple as

function filter_media_send_to_editor( $html, $id, $attachment ) {
  return $html;
}

add_filter( 'media_send_to_editor', 'filter_media_send_to_editor', 10, 3 );

in functions.php. No output. If I set a breakpoint within the body of that function, my debugger doesn't catch it. The only other thing unusual about my setups that I can think of is that all of my WordPress installs are on Vagrant boxes or Homestead.

Closing. Figured out this is totally an issue on our end. We have multiple vagrant boxes on the same system and whatever was getting returned was going to the a different wordpress install/vagrant box.

Going to chalk it up to a configuration error on our end. Sorry for the inconvenience.

All good, thanks for the follow-up!
