Upload Files to Web Server

Demonstrates how to upload files 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.

use chilkat();


$http = new chilkat::CkHttp();

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

#  Build a HTTP request with the files to be uploaded:
$req = new chilkat::CkHttpRequest();
$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->put_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 != 1) {
    print $req->lastErrorText() . "\n";

}

$success = $req->AddFileForUpload("file2","dude.gif");
if ($success != 1) {
    print $req->lastErrorText() . "\n";
    exit;
}

#  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.
