PHP List:

I am doing a pretty cool gig and I have decided to map a Nodal network
using a "threaded BBS"-type +/- hierarchical system. I am imitating
Chapter 29 in the SAMS _PHP & MySQL_ book and I love the model.  I am not
having a lot of luck in mapping my MySQL DB to the model and not only that
but I am getting funny "triple" repeats and recursive memory bloats and
all sorts of terrible things.

I am using my DB schema/structure:

connections(node1,node2)
contacts(contid,node,admintech)
maps(node,maptype,mapurl)
node_types(typeid,typedesc)
nodes(nodeid,nodename,toplevel,nodetype,moreinfo,city,state,country,homepage,bandwidth)
peers(peer1,peer2,transitfrom,transitto,bandwidth)
people(personid,firstname,lastname,phone,cell,fax,email,moreinfo)
updown(upnode,downnode,bandwidth)

The only tables I am using for the "threaded nesting bulletin board" model
is:  nodeid, upnode, downnode, nodename, moreinfo

A list of the files follows:

(You can look at the source at http://www.zdev.net/i2/ I didn't include
db_fns for the obvious reasons):

data_valid_fns.php
db_fns.php
discussion_fns.php
include_fns.php
index.php
new_node.php
output_fns.php
store_new_node.php
treenode_class.php
view_node.php
images/
    blah_blah.gif
    cancel.gif
    collapse.gif
    expand.gif
    index.gif
    minus.gif
    new_post.gif
    plus.gif
    post.gif
    reply.gif
    spacer.gif

And this is how it barfs:

So, what do you think?

It should look like:

Internet2 Nodes
+ Abilene
+ DANTE

And when you click on the "+" or "-", then you should see it cascade only
to the children.  All I get is nasty "memory overflow" fun!

And not three copies of everything!  Here is a little bit of a way the
data looks:

mysql> select * from updown limit 30
    -> ;
+--------+----------+-----------+
| upnode | downnode | bandwidth |
+--------+----------+-----------+
|      1 |        2 |         0 |
|      5 |        6 |         0 |
|      6 |        7 |         0 |
|      2 |        3 |         0 |
|      2 |        4 |         0 |
|     17 |        8 |        20 |
|     17 |        9 |        10 |
|     17 |       10 |        20 |
|     17 |       11 |        10 |
|     17 |       12 |        20 |
|     17 |       13 |        20 |
|     17 |       14 |        20 |
|     17 |       15 |        20 |
|     17 |       16 |        30 |
|      6 |       17 |         2 |
|      5 |       17 |        34 |
+--------+----------+-----------+

The IDs under 'updown.upnode' and 'updown.downnode' equal 'nodes.nodeid'

And here is the other table, 'nodes':

mysql> select nodeid, nodename from nodes limit 20;
+--------+----------------------------------------------------+
| nodeid | nodename                                           |
+--------+----------------------------------------------------+
|      1 | Abilene                                            |
|      2 | CALRen2                                            |
|      3 | UCLA                                               |
|      4 | Stanford                                           |
|      5 | DANTE                                              |
|      6 | JANet                                              |
|      7 | Cambridge                                          |
|      8 | Dublin City University                             |
|      9 | Dublin Institute of Technology                     |
|     10 | National University of Ireland, Galway             |
|     11 | National University of Ireland, Maynooth           |
|     12 | Trinity College                                    |
|     13 | University College, Dublin                         |
|     14 | University College, Cork                           |
|     15 | University of Limerick                             |
|     16 | Network of Institutes of Technology (ITNet)        |
|     17 | HEANet                                             |
+--------+----------------------------------------------------+

I didn't include 'nodes.moreinfo' because the table is prettier this way.

Anyway, If you can please help me, or at least point me in the pants or in
the right direction -- and if I missed something ala glaring omission,
then please ask any questions!

I am using PHP ala http://www.internet2.edu/arena/29/info.php

Cheers,

Chris

PS: Thanks in advance!
