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.
Thanks,
