Hi,
Id like to know if its possible to have an application fill an online form with data and post it as well. The form posts data via cgi. If so how ?
Thanks and regards

When you try Synapse, then you can find demo sample for this in
disribution package. ;-)

You can do it easily with ICS. Use the HTTP client component to do exactly
what a browser do when submitting a form (Post or Get method). If you need
help, please use ICS support mailing list where a team will answer your
questions and about 1000 subscribers wshare their experience with ICS.

Hi Francois,

I already am using Indy 9. Is it not possible with Indy? If not then i'll try ICS.

Thanks and Regards

I don't see why you couldn't do this with INDY.

Off the top of my head I would do something like the following:

First do a HTTP GET to retrieve the HTML form you want to fill in.

Then parse the HTML form and figure out what you need to fill in and fill it
in.

Then do a HTTP POST and submit the HTML form that you just parsed and filled
in to the appropriate place.

All of this can be done using the INDY HTTP client.

Yes, of course it is possible with Indy. TIdHTTP has a Post() method which
can accept post data. Have a look at the TIdMultiPartFormDataStream class.

Hello,
Ok, the form has a few fields like "edit1", "edit2" ...etc and a submit button: "button1". The form is named "TrialForm" and the submit action is linked to a cgi script.
So using idHTTP how can i get along this ?

Assuming the following HTML:

You would do the following with Indy:

var
PostData: TIdMultiPartFormDataStream;
Result: String;

PostData := TIdMultiPartFormDataStream.Create;
try
PostData.AddFormField("edit1", "TextFromEdit1");
PostData.AddFormField("edit2", "TextFromEdit2");
Result := IdHTTP.Post("http://www.somesite.com/somescript.cgi",
PostData);
finally
PostData.Free;
end;

Parsing out the values from the HTML is your own responsibility separately.
Indy has no facilities for handling that.
