Fill in HTML form automatically?

[callaghan001]

Hi All,

I am trying to (transparent to the user) fill in a html form a press submit. I am trying to prevent the user having to log in every time they visit the page so I intend to store their password and then pass it to the form when needed. Does anybody have any idea how I could achieve this.

Username: <INPUT TYPE="text" NAME="user_id"  SIZE=25 MAXLENGTH=50 tabindex="1">
Password: <INPUT SIZE="25" NAME="password" TYPE="password" tabindex="2">

That is an example of the form I am trying to fill in and the submit button would be as follows:

<input type="image" alt="Log In" name="Login" src="/images/ci/formbtns/login_off.gif" tabindex="3" border="0">

Any help on this would be brilliant and I have been trying to come up with a solution for some time,

Thanks,

Callaghan001.

When your web browser submits a form, what it's doing is posting the values for the fields in this format:

"name1=value1&name2=value2", so in this case "user_id=whatever&password=whatever".

You'll need to gather where the form is submitted (it's in the HTML source code, usually called the "action" or something like that), then you need to post the data yourself.

A very simple example of this would be something like:

NSString * postString = [NSString stringWithFormat: @"user_id=%@&password=%@",theUserName,thePassword];
NSData *myRequestData = [NSData dataWithBytes:[postString UTF8String] length:[postString length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString: @"http://www.theaddress.com"]]; 
[request setHTTPMethod:@"POST"];
[request setHTTPBody:myRequestData];
NSData * response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
[request release];

Hope that helps!

That helps a lot and I think it may be the way to go, but one question though, I think the webpage calls some javascript on the the entries before sending them back to the server, I think some base64 encoding and MD5...should I be worried about that too?

Thanks for the help,

Yeah, you should try to mimic it exactly.
