How come I never get an answer about WP’s awful editor?

i am having a similar problem but i have isolated it to captions, seems to add blank <p> </p> before [caption and after /caption]
this only seems to get added when switching between the html and visual editor.

if i save the page and switch between html and visual editor it will add another, and do this as many times as i save and switch between.

i have tried wrapping the caption with paragraph which it strips out and adds the <p> </p> before and after. when its wrapped with a div it will also add the <p> </p>

i am using tinymce advanced and have ticked the stop removing <p> and
setting in timymce advanced. and also tried commenting out the lines in tadv_replace.js this only removes the <br “class=spacer_” /> from <p><br “class=spacer_” /></p>

After 6 months of absence from this thread I return and see nothing of significance has happened. That was a little disappointing.

It seems that this must be a very technically challenging task – much more so than all the other bells and whistles that the WordPress developers have introduced since last it would appear. Otherwise my take is that they would have fixed this a long time ago. Surely they must be aware of it. This problem has, aside from the permalinks implementation, been the biggest downside to WordPress ever since I started using it.

WordPress developers seem to be pretty active elsewhere on the forum so why not here? There’s this guy named Otto? Where are you Otto? Come and help us out please .-)

In other threads around here, I’ve heard rumour that a different editor solution is possible being worked on.

Not sure how high of a priority it is…. since the editor seems to be just fine for the needs of many. But I know I’ve seen talk of it

Maybe just a wild idea, but has anyone tried using the content_filtered_save_pre filter to strip off trailing spacers? Or is the problem more than just trailing ones?

According to the Codex here, the content_filtered_save_pre filter filters the content before it is saved to the database. If that is indeed true, you should be able to use some pattern matching logic to remove trailing spacers.

Is the problem only with extra trailing spacers?

If you want to try a filter to remove trailing spacer_ lines, put this in your functions.php:

<?php
function content_save_pre_function ($content) {
// A brute-force attempt to remove trailing <p><br class="spacer_" /></p> lines
// from post text.
$pattern = '#(<p><br class=..spacer_.. /></p>.)#m';
$pieces = preg_split($pattern,$content,-1,PREG_SPLIT_DELIM_CAPTURE);
if (sizeof($pieces) > 1) {
  $new_content = '';
  $drop = true;
  for ($i=sizeof($pieces) - 1;$i >= 0; --$i) {
    $piece = $pieces[$i];
    // Drop until we find a non-empty line that does not match the pattern.
    if ($drop && preg_match('#^\s*$#',$piece)) continue;
    if (!preg_match($pattern,$piece)) $drop = false;
    if ($drop) continue;
    $new_content = $piece . $new_content;
  }
  $content = $new_content;
}
return $content;

}
add_filter('content_save_pre','content_save_pre_function');
?>

If you try it, please let me know if it works.
