Programming Consultant needed	Quote \| Reply \| Private Reply

Hi Folks,

I've been contracted to develop a multi-website posting engine. I'd like to find a consultant familiar with mod_perl / Apache::Perlrun, LWP::UserAgent and HTTP POST operations. I'll be doing the programming, but would like someone to review my code and answer some specific questions. Here are a couple of typical questions:

1) How does a browser normally prepare to POST multiple select menus and / or multiple fields with the same name attribute (eg checkboxes), and how do I emulate this when preparing the data hash for the request object? IE is there a specific delimiter, do I just append all selected fields into a single string or is there some way to construct multiple values with the same key in the request object?

2) How do I prepare the headers for www_authenticate or authorization?

I may also ask you to review my database schema (MySQL).

If you're interested, please e-mail me directly at kencl@home.com to discuss this further. Thanks.

Each value of same-name fields are reproduced in key=value fashion as if they were the only one, and then stringed together later on as you would for any other field you need to add either directly with HTTP::Request's new or content methods.

Code

    $req = HTTP::Request->new( POST => $url ); 
    $req->content("field=value1&field=value2&ad=nauseum");

Personally, I find it much easier to use HTTP::Request::Common instead, and let it build my query strings for me.

Code

    $req = POST $url, [ 
             "field" => "value1",  
             "field" => "value2", 
             "ad"    => "nauseum",  
           ];

2) How do I prepare the headers for www_authenticate or authorization?

There's a few ways, but the easist is probably using HTTP::Request's authorization_basic method.

Code

    $req->authorization_basic( "username", "password" );

Other alternatives include tacking on an Authorization header, using LWP::UserAgent's credentials method, or overriding LWP::UserAgent's get_basic_credentials; each of which have their pros and cons.
