Posted on 2009-05-07
Hi there,
Having a small problem with a form, when it is submitted it inserts a duplicate record in the database, any idea what could be causing this?

if there is no page reload caused by anything in your code after you submit your form - and I don't see
from your code where the page-reload could happen (your page with form is not 'home', is it?)
More likely I sense that trouble could be in your SQL-code, here:
$add = oci_parse($connect,"INSERT
Not sure about the JOBGROUP_ID_SEQ.NEXTVAL syntax, but somehow my intuition says it could be
a reason (first inserting into the next available id, then again because of nextval adding an id with same
values ??)
but not sure about it, since I am not experienced with Oracle SQL and highly recommend you to post this issue
in the Oracle SQL zone, for real experts to contribute from there, too.

I have disabled all includes apart from oracle.php which has the database connect string and still no luck

some remedies given too in above url, hope it helps.
One tip from me added:
run a html validator on your site and make sure any code is absolutely neat and valid,
html, css, php, javascript ...
