Cannot post form completed with Javascript

[SteveYoungTbird]

I am starting to experiment with AJAX and have hit a problem which I am
sure must be obvious to an experienced programmer but I cannot seem to
solve it. I have successfully managed to submit a form via Javascript
which is read by a PHP script which then puts the data into an SQL
database. The script is here:

http://steveyoung.myftp.org/secureArea/http_putgettest.html - just
input new names and click the "save" button.

But when I write the data to the form via Javascript I get an MySQL
warning "Duplicate entry '' for key 1" which means that the form is
submitted empty. Also I echo the first item in the form to prove that it
is empty.

I would be very grateful for any help with this.

Regards, Steve.

Hi,

Don't echo the first item, simply put out all you received.
From PHP start with:

echo "<pre>";
printr($_POST);
echo "</pre>";

and you'll see everything that PHP received from the form (assuming you
use Method="POST").

So your form doesn't get its right values set.

I am not going to dive into your code, but do you see any errormessages
in the JavaScript error console?
(If you are on IE, start using Firefox right away. All serious
developers work in FF and test on IE later.)

Typo:
that should be:
print_r($_POST);

Nice tip, and it helped me isolate the problem which was I was using
"id" instead of "name" and therefore the data wasn't being submitted.

Thanks, Steve.
