Getting rid of bugs I never thought I would have

Overall, I am happy with the progress on my pet TAXA project but the
journey is proving to be like riding over a rocky road. The most
recent effort at a functional addition has been a form to let users
decide whether 2 of three types of data will show (general,
woodworking & numeric). The general
data for each wood should always so and the users should be able to
choose if either or both of hte other two should show (using include files).
At first in the form's simplest unformatted form, I got it working
fine (and I rejoiced ....). Then when I tried to put it into a table
to pretty it up again --- I would no longer work (... almost). I
tried all kinds of things. If you temporarily hardcode the choices,
the two tables show or do not as desired. Somehow
the user choices are not latching to the control lines. Every time
you click on the submit button
(named ''Choose Data to View"), it cycles back to the same page like it should.
Now the weird things start. Yesterday, in reviewing everything before
submitting to this forum, I
decided I should try it again ---- and to my astonishment for a while
--- it worked! I could choose
the working data checkbox, the woodworking checkbox or both and they
would show. Don't
check either and they didn't show just like should be. That was short
lived, though(!). It hasn't
worked since. Ahem..... talk about flaky.....
But then I noticed another problem. To activate the user choice you
have to click on the submit button of course. When I cycled through
is when I noticed that now on species detail sheets that
are set up to show a scan of the wood being reported on the scan that
first showed disappears,
leaving only the 'missing' graphic' symbol only.
So now I have two consternating problems:
1 - How do I get the form to let users choose what data
tables to show to work consistently
well all the time? If it works mysteriously some of the
time, my code should be fairly
close to what it needs to be <fingers-crossed>.
2 - How do I keep the scan showing always? I realize that
each time the submit button is
hit, the location for what scan file (all .jpg) should
show gets lost. All scans are kept in
and alphabetical list of folders according to the first
letter of the (botanical) name of the wood being showed:
/taxa/wood_scans/gallery_a/<filename>
/taxa/wood_scans/gallery_b/<filename>
/taxa/wood_scans/gallery_c/<filename>
/taxa/wood_scans/gallery_d/<filename> and so on, but have been loaded into
the 'species' MySQL file (species.sql) also in
column 'picture_filename'.
I looked at various examples on the Net but could not
see why it won't consistently work.
Probably the best way to understand what is happening is to try out
the site. You can find it at (as before) www.prowebcanada.com/taxa.
On the left side menu under 'Woods by Alphabet", use the
menu choice 'Woody Species'. Pick a name with a camera icon in front
of it in the range of A,B or C
where there is more data for now). It doesn't matter whether or not
you use the alphabetical menu first.
As long as you picked a species with a camera beside it, you should
see a scan of what that wood
looks like --- as long as you have not yet used the user choice form
below the Genera Data table. Now try picking if you want either the
woodworking data and/or Numeric Data tables to show. Click
the submit button and notice it does recycle ok ---- but it is a
minor miracle if the tables really do
show. Meanwhile, the graphic scan has disappeared <frustrating sigh....>
This time I think I had better show the code for the entire file :-(
. All this is happening in file
'displayspecies.php'. There are many debugging commented lines you
can ignore ;-) .
Glad for the help,
Bill Mudry

The programming works well now but there is a lot of data to
be stored.
It is a huge job that will take a long time to get
most of it in. Till then, there may seem
to be a lot of data missing --- because there is!
</P>
<P align='left' class='webmessage.p'>
This species area is still under development. It is the
bottom of the botanical tree.
No further elements are under species. There are
three categories for species data;
GENERAL DATA, WOODWORKING DATA AND NUMERIC TEST
DATA. General Data will always be
shown while future programming will let the reader
choose if woodworking or numeric test data shows.

Some species will have a lot of information for them, a few
even for all three data areas. The species that TAXA
reports ranges from massive wood from the largest trees in the
world weighing tons to ssmall shrubs that are
"woody" but without enough wood to be used for anything other
than academic interest. Some woods have been
researched and tested thoroughly while others are amongst the
thousands that are only known by some basic facts.
This shows why some data areas are rich with text and pictures
while others have very little known about them.
For such rare, obscure or small sized species, listing
woodworking or numeric test data is neither practical or
useful.
