Hi,

I have a problem with syntax highlighter in bbpress (plugin). Normaly, after I’ve used Crayon and paste the example code

void loop()
{
digitalWrite
}

it generates in the background (if I switch to text mode)

<pre class="lang:arduino decode:true crayon-selected">void loop()
{
digitalWrite
}</pre>

It works good for admin, but if somebody else (member) try to post a code, the tag </pre> disappears, so his code will be not highlighted and in the published post I can see the code and a part of Crayon’s tag like this

<pre class="lang:arduino decode:true crayon-selected">void loop()
{
digitalWrite
}

I’ve noticed about restrictions in html-tags etc. but as I can see in formatting.php pre is allowed tag.

What is the problem?

Thanks in advance.

I just had a play with this and you are correct, it works for administrators/keymasters but not standard ‘participants’ or ‘anonymous’ users.

Grab this custom KSES plugin I have here https://gist.github.com/ntwb/7797990

I just added class to to the pre section as that is where the issue is, pre is allowed but <pre class="whatever"> is not.

Double check any of the other allowed tags and/or remove ones you don’t want/need.

Edit: I just double checked against the default bbPress allowed tags and all are there, you may or may not want the table sections, up to you. I also made a note to add class as an allowed tag of pre for bbPress core, I can’t think of a reason for us not to add this by default.

I just added a patch for this, so unless someone comes with a reason to not include this it will be included in bbPress 2.6.

I post only to confirm that I have a similar issue.

I have enabled the Crayon Button to Post code over the crayon Popup.
It inserts allways the pre Tag with a class attribute.
If I Post as Admin with Crayon Syntax Highlighter in bbPress all is fine.
If I post as a User the angle brackets of the preliminary pre Tag are geting masked like so:
& lt; pre class=”lang:arduino decode:true crayon-selected” & gt;

If I remove the class attribute and put in a simple < pre > all works fine.

@netweb Thank you for your workaround I will Ty it!

Hi Stephen,

Thank you for this workaround.
I’ve already found this solution ca. 2 weeks after the request here.
I thought there is no interest to fix it, so I’ve never written about a solution here.
Unfartunatelly the notification email about your reply landed in my spam folder.

I’ve posted my workaround on my own blog (www.5volt-junkie.net, German) like a notice for me, if this issue appears again.

I’m very impressed, that you guys are tracking this kind of little bugs 🙂

Thank you!!!
