[rt-users] MySQL Query from PHP

hey,

Thanks for the direction. I had been trying to do joins off the wrong
table and did not include Transactions in my statement.

As an FYI, the query was something like this:

$query = "SELECT t.id, t.type, t.OldValue, t.NewValue, u.Name,
t.Created, a.Content FROM Transactions t JOIN Users u on u.id =
t.Creator JOIN Attachments a on a.TransactionId = t.id WHERE t.ObjectId
= '$ticketId'"

Now I have a fully functional PHP interface for people to view the
status of tickets without having to log into RT itself. Users can select
between Queues and see the progress. 

All that's left is to hack together a RegEx to parse Attachments.Content
to the correct format and I'm golden.

Again, thanks for everyone's time and comments. Its much appreciated.

RT's database is heavily normalized.

You'll need to use "left join" in your mysql statements.  Here's an
example:

select
t.id,q.Name,t.Subject,t.FinalPriority,t.Status,t.Created,t.LastUpdated,t
.Resolved,u.Name,u.Name from Tickets t left join Users u on u.id =
t.Owner and u.id = t.LastUpdatedBy left join Queues q on q.id = t.Queue
where t.Subject like '$searchsubject' order by t.id;

where in this case I'm searching on a string, $searchsubject, and only
returning specific fields.  Note that I'm left joining on the Users and
Queues tables to get the real name of the people involved, not just the
id.

Here's another one where I'm searching on an IP:

select
t.id,q.Name,t.Subject,t.FinalPriority,t.Status,t.Created,t.LastUpdated,t
.Resolved,u.Name,u.Name,c.Content from Tickets t left join Users u on
u.id = t.Owner and u.id = t.LastUpdatedBy left join Queues q on q.id =
t.Queue left join TicketCustomFieldValues c on c.Ticket = t.id where
c.Content like '$sourcenum%'

Note I brought in the table TicketCustomFieldValues as source IP is one
of our custom fields.

For Attachments to a ticket, I actually call a different script and pop
it up in a separate browser window using javascript.
Here's the popup code:

<ahref=\"javascript:window.open('searchtickets.php?tid=$result[0]','Popu
p_Window','toolbar=no,location=no,directories=no,status=no,menubar=no,sc
rollbars=yes,resizable=yes,copyhistory=no,width=1000,height=900,top=200,
left=300')&&void(0)\">

and here's the search from the other script - I'm passing the ticket id
as $tid:

select t.id,t.Type,t.OldValue,t.NewValue,u.Name,t.Created,a.Content from
Transactions t join Users u on u.id = t.Creator join Attachments a on
a.TransactionId = t.id where t.Ticket = '$tid'"


Hope this is enough to get you started.  My needs came from the fact
that I had 3.0.10 on a linux box for the old ticketing system, and 3.6.1
on a different OS for the new, and considering the upgrade path involved
here, it was simpler to write some php code.
