[ODK Developers] Posting the form definition file to ODKaggregate

Development
1

I have no idea what that response from Curl means.

Note that form submissions into ODK Aggregate use standard plain old form
posts. If you have a working ODK Aggregate, you can see the web page for
form submission by opening a browser and pointing to .../formUpload. You
can then view source on that page and reconstruct what you should be
sending to the server.

i.e., if you had the ability to log into opendatakit.appspot.com, you could
get to this plain old web page via:

http://opendatakit.appspot.com/formUpload

From there, your knowledge of Curl should enable you to construct the
appropriate submission.

Hi there,

I am working on a PHP application to manage forms and form data from
outside ODK.
My idea was to post the form definition file from within the application
using curl.
Something like:

$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_VERBOSE, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
curl_setopt($ch, CURLOPT_URL, '

http://myAggregateserver.org/ODKAggregate/formUpload');
curl_setopt($ch, CURLOPT_USERPWD, "myUser:myPassword");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_POST, true);
$post = array(
"form_def_file"=>"@myformdefinition.xml",
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$response = curl_exec($ch);

This does not work however.
The application returns: "Resource id #2"

Is there anyone who has an idea how to do this?

Cheers!

Yes. See /formUpload

At the moment, the servlet is not reporting invalid forms correctly. Seems
to be a 1.3 regression.
If it were reporting invalid forms correctly, you would see an error page
other than the over-quota page that it now seems to display.

Hi everyone,

I have a questions along the same line. We have a use case for one of our
upcoming installations where we would be dynamically designing forms and
want to be able to upload them to aggregate through some API call (so that
collect application can download this from the server, fill in the values
and submit it back to aggregate). I see from above that form submission is
a simple http post method. Is it the same if we are uploading a new form
(empty...not a data submission) for a new survey that we now want to
conduct without using the designer etc.

Thanks for any help or suggestions in this regard
