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'.
<snip>
1) Fix 2 and I think 1 will be more easily traced.
2) I did not see that you were keeping the species_name once the
user clicks on "Choose data to view." You could add a hidden input
field that saves the value and returns it to the script. Something like:
echo "<input type='hidden' name='species_name' value='{$species_name}' />";
Once the user clicks the button to select the data they want to
view, PHP has no idea what species they were viewing.
That might be a good suggestion, James. I will try this shortly
tonight. I will let you know after.
Can you possibly figure out why the form is working so flaky, now? As
above, it worked when not in a table for formating (quite well at one
early point), basically has not worked except briefly one morning
(without any code change I know.....) and not since. I just checked
now and it doesn't work.
The URL at the top shows as
http://www.prowebcanada.com/taxa/displayspecies.php?show_woodworking=OFF&show_numeric=OFF
and that is even after I have chosen both user check boxes on and
clicked on the submit button. Both should read on but both show OFF.
Thanks,
James
Here's hoping that you or someone can catch what I have not quite
coded correctly.
