RT eats table-tags in html-emails

RT Users

RT is pruning the table, td and tr -tags from emails when you look at them at
the Ticket/Display.html -page, is there a way to stop RT from doing this?

I tried enabling Rich text (HTML) in my preferences and looked at
\share\html\Elements\ShowMessageStanza but I’m just a beginner when it comes
to perl.

I’m currently on RT 4.2.6 and use apache, mod_fcgi and nginx as a reverse
proxy.

Thanks in advance,
vinz

Hi Vinz,

You need to adjust the allowed tags in the HTML::Scrubber object by adding a
Web_Local.pm:

https://www.bestpractical.com/docs/rt/4.2/RT/Interface/Web.html

Here is what I am using because I wanted to allow the tables to have colors:

package HTML::Mason::Commands;

Let tables through

push @SCRUBBER_ALLOWED_TAGS, qw(TABLE THEAD TBODY TFOOT TR TD TH);

Allow bgcolor to be set

$SCRUBBER_ALLOWED_ATTRIBUTES{bgcolor} = ‘^\s*#[a-fA-F0-9]{3,6}\s*’;
1;

Make sure to set the option in your RT_SiteConfig.pm

Set($TrustHTMLAttachments, 1);

I think that is all I needed to do. Then restart after clearing your Mason
cache.

Regards,
Ken

Another solution in recent versions of RT is to install the HTML::Gumbo
module from CPAN, which should automatically enable correct display of all
HTML in tickets without any coding.On Sat, 17 Jan 2015 1:11 am ktm@rice.edu ktm@rice.edu wrote:

Looking at the RT_Config documentation, I think you might need to enable
the $TrustHTMLAttachments setting. I know I’ve enabled that in my local
installation.

You might also need to increase the $MaxInlineBody setting from its default
of 12,000 bytes (or set it to 0 to disable size limiting altogether), since
things with HTML tables in my experience tend to frequently exceed that
limit.On 19 January 2015 at 18:41, Guadagnino Cristiano < guadagnino.cristiano@creval.it> wrote:

IIRC this is not very well documented… just a note among the release
notes.

I have both already set. Is it working in your system?
Did you need to add something to the config command line?

HTML tables are mostly displaying as expected on my installation (ignoring
missing images and CSS). I’m running v4.2.7 though; I guess it’s possible
that a regression has occurred in a later version.

There are no other relevant settings in my RT_SiteConfig.pm file, and I’m
90% sure that I didn’t add any special flags when I ran the “configure”
script.

Looking at the code, HTML::Gumbo would be ignored if it failed to install
properly for some reason. Are you seeing anything interesting in RT’s
debug logs? I remember having to grab a very fresh HTML::Gumbo version
because of some installation issue I encountered with an older (but still
somewhat recent) one.

Lastly, you’ve probably already done this, but for the sake of
documentation, RT would need to be restarted after the installation of this
module.On 19 January 2015 at 18:56, Guadagnino Cristiano < guadagnino.cristiano@creval.it> wrote:

Thank you all for your replies.
I used the solution from Ken. I enabled HTML-Attachments and created a \local\lib\RT\Interface\Web_Local.pm
Maybe I’ll try the “HTML::Gumbo”-Solution to.

Alex,
you were right: HTML::Gumbo installation failed on my box, but I did not notice it initially.

Trying to reinstall HTML::Gumbo now, I noticed that ‘libtoolize’ was missing, so I installed it.
Unfortunately it fails again because it wants autoconf >= v2.65, and there is only v2.63 in CentOS repository.

I’ll have to wait until CentOS updates the repos.

Thank you!

Bye
