[rt-users] Interfacing with RT via PHP

AFAIK, Chris, you're more or less out of luck. It's not that somebody
else hasn't done this already (I don't know, maybe they have), but I
think a lot of people give up on PHP after they get more insight to
HTML::Mason and the design of RT. 

Also, I've replied some more throughout the text of your message:

That's a very good justification. However, you could still reference
an HTML page, couldn't you? Rewriting a year's worth of work sounds
bad, but I don't know why you'd need to rewrite it all, couldn't you
just link over to the HTML::Mason page?

But it appears you have other concerns listed below. And, of course,
you add complexity to the maintenance of your webserver by installing
RT and all its dependencies on there.

Yeah, but RT's API solves a lot of problems with accessing the database
directly. For example, good luck trying to query the database to find
out which ticket id you just inserted. Using RT's modules, when you
create the ticket, you have a return value that tells you that info.
I'm not sure there's a pretty way of doing it, but I'm not an expert,
either.

I don't know that anyone on this list will flame you for expressing
frustrations with mod_perl. :-) That's understandable. Mod_perl is
stinky, IMHO as well. I like fastcgi a lot better.  It improved
performance at my site significantly, though I'm still not using
fastcgi in production because the rt mason handler for fastcgi doesn't
do what I'd like it to do with cookies (and what the mod_perl mason
handler currently does, methinks).

You should consider giving fastcgi a try.

Don't know whether fastcgi is UNIX specific or not. I'm guessing it is.

Yeah, emailing the ticket from the web is crappy, IMHO. I agree.

Not sure what you mean here. I guess you're doing some kind of
site-wide include stuff for your pages. But it doesn't really matter
whether or not I understand, I think, since your other justifications
for using PHP are pretty substantial anyway.

You may want to look in $RTPREFIX/lib/RT/ for some of the code (if you
haven't already), but I spent about five minutes looking for it and
couldn't find the database insert stuff in there. And there are more
clueful individuals about than myself.

Anyway, I'd still encourage you to look at using fastcgi as opposed to
mod_perl because fastcgi's performed much better for me. But, if PHP's
a better fit for you, best of luck with it.
