Trying to disable color tags for some users

[NovoCiv]

My members have requested the ability to disable color tags just as they can disable images. I created a profile field for this and have been trying to determine the correct hook and code to make this work. The closest I've gotten is:

if ($vbulletin->userinfo['field5'] == "Yes") {
global $vbphrase, $db;
$post_text = $db->query_first("SELECT pagetext FROM " . TABLE_PREFIX . "post WHERE postid = $post[postid] ORDER BY dateline ASC");
$post_color['pagetext'] = preg_replace('#\[color=sienna\](.*?)\[/color\]#si', '\1', $post_text[pagetext]);
$post_color['pagetext'] = preg_replace('#\[color=black\](.*?)\[/color\]#si', '\1', $post_color[pagetext]);
$post['message'] = nl2br($post_color['pagetext']);
}

While this removes the sienna and black color tags, it leaves the rest of the BBcode unparsed.

I'm looking for a way to just remove the tags without unparsing everything else, and possibly a more efficient way of removing colors (than one at a time).

You could do this: create a new style and then in a plugin using hook bbcode_fetch_tags:

global $style;
if ($style['styleid'] == X)
    $tag_list['option']['color']['html'] = '%1$s';

where the X is the new style id. I think this works because posts are cached by style. If you used a profile field instead I don't think it would work because of post caching.

Obviously this isn't a good solution if you already have a number of styles that a user can choose. I'm not sure where you are putting the code in your example, maybe there's another way to do it (like maybe you could replace all <span color="xxx">whatever</span> in the post text).

Sorry forgot to mention this is in a plugin at the postbit_display_complete hook.

A new style is not a viable option.

OK, how about this:

if ($vbulletin->userinfo['field5'] == "Yes")
    $post['message'] = preg_replace('#<font color=".*?">(.*?)</font>#si', '\1', $post['message']);

Hey that worked great! Thanks!

Thinking about it more, it's probably not going to work in all situations since the SIZE and FONT bbcodes also end up as <font> tags, so something like:

This is red and big still red

would probably end up with "still red" being size 5 instead of normal.

That's totally worth it unless someone has an easy fix.
