Submitting forms with Zinc

Can Zinc do this easily (e.g. automatically handle hidden fields)? If not, is it planned? Where can I find an example?

Thanks.

Sure, have a look at ZnClientTests>>#testPostForm (and possibly #testPostMultipart).
The API you are looking for is in ZnClient>>#formAt:put: (or #formAdd:) and friends.
This would be an example:

ZnClient new
url: 'http://myserver.com/login';
formAt: 'username' put: 'john';
formAdd: 'password' -> 'secret';
post.

HTH,

I tried this with my wordpress site:
ZnNeoClient new
url: 'http://seandenigris.com/blog/wp-login.php';
formAt: 'log' put: username;
formAdd: 'pwd' -> password;
post.
which failed (I also tried the form element id's instead of names).

The following worked via Ruby's Mechanize:
a = Mechanize.new { |agent|
agent.user_agent_alias = 'Mac Safari'
}
page = a.get('http://seandenigris.com/blog/wp-login.php')
form = page.form_with(:name => 'loginform')
form.log = username
form.pwd = password
results = form.submit
results.body

Sean,

It is hard for me to read the Ruby code, but I seems as if they first get the page/form, modify it and then submit it. It is probably important to either do the same, or at least supply all needed fields (there are some hidden ones, look at the HTML source).

Maybe you could try this:

ZnClient new
url: 'http://seandenigris.com/blog/wp-login.php';
formAt: 'log' put: 'sean';
formAt: 'pwd' put: 'password';
formAt: 'redirect_to' put: 'http://seandenigris.com/blog/wp-admin/';
formAt: 'testcookie' put: '1';
post.

In any case, I get an unknown user error back, so the submit basically worked. Now you have to find out what you have to supply as form elements. Let me know how it goes.
