Upload Files with Params

Demonstrates how to upload files with extra form parameters from an application to a web server. Note: There must be something provided on the server-side to consume the upload. It could be an ASP or ASP.NET script, Perl, C++ CGI, PHP, Ruby, etc,. However, uploading via HTTP is not the same as uploading via FTP where the FTP server handles receiving the file and saving to disk.

<?php


$http = new COM("Chilkat.Http");

//  Any string unlocks the component for the 1st 30-days.
$success = $http->UnlockComponent('Anything for 30-day trial');
if ($success != true) {
    print $http->lastErrorText() . "\n";
    exit;
}

//  Build a HTTP request with the files to be uploaded:
$req = new COM("Chilkat.HttpRequest");
$req->UseUpload();

//  The URL we'll be posting to is:
//  http://www.chilkatsoft.com/receiveUpload.aspx
//  Therefore, the path part of the URL is:
$req->Path = '/receiveUpload.aspx';

//  Note: You may test uploads to this URL, but anything over 80K will be aborted on the receiving side.

//  Add some files to the request:
//  The 1st argument is an arbitrary name.  It's the POST form field name.
//  The 2nd argument is the filename currently existing on
//  the local filesystem.  It may include an absolute or relative
//  path, or no path at all if it's in the current working directory.
$success = $req->AddFileForUpload('file1','hamlet.xml');
if ($success != true) {
    print $req->lastErrorText() . "\n";
    exit;
}

$success = $req->AddFileForUpload('file2','dude.gif');
if ($success != true) {
    print $req->lastErrorText() . "\n";
    exit;
}

//  Additional non-file params may be added to the POST request
//  by calling AddParam:
$req->AddParam('extraParam1','abc123');
$req->AddParam('extraParam2','This is the content for my POST param');

//  Send the HTTP POST and get the response.  Note: This is a blocking call.
//  The method does not return until the full HTTP response is received.
