(PHP Extension) HTTP multipart/form-data Upload

Demonstrates how to upload files to an HTTP server using a multipart/form-data POST.

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$http = new CkHttp();

$req = new CkHttpRequest();
$req->put_HttpVerb('POST');
$req->put_ContentType('multipart/form-data');
$req->put_Path('rcvFormDataUpload.aspx');

// Send an "Expect: 100-continue" header in the request.
// This causes the HTTP server to end a 100-continue response
// immediately after receiving the HTTP header.  The client
// (Chilkat) will receive this intermediate response, and if
// it's not an error response, it knows that the HTTP server will
// accept the data that is forthcoming.
// The alternative is to get an error response after trying to upload
// the entire contents of the files.
$req->AddHeader('Expect','100-continue');

// Call AddFileForUpload2 for each file to be uploaded in the HTTP multipart/form-data POST
// To allow Chilkat to determine the content-type automatically based on file-extension,
// call AddFileForUpload instead.

// The 1st arg is the filename passed in the HTTP request.
// The 2nd arg is the path in the local filesytem.
// The file is not loaded into memory.  It is streamed directly from the file
// when the HTTP POST is sent.
$success = $req->AddFileForUpload2('starfish.jpg','c:/qa_data/starfish.jpg','image/jpg');
if ($success != true) {
    print $req->lastErrorText() . "\n";
    exit;
}

$success = $req->AddFileForUpload('something.pdf','c:/qa_data/something.pdf');
if ($success != true) {
    print $req->lastErrorText() . "\n";
    exit;
}

// Its also possible to add a file from a string:
$success = $req->AddStringForUpload('test.xml','test.xml','<abc>This is the test.xml content</abc>','utf-8');
// We'll assume success since no files are involved..

// This sends the HTTP request (with 3 files being uploaded) to
// http://www.mywebserver123abc.com/rcvFormDataUpload.aspx

// resp is a CkHttpResponse
$resp = $http->SynchronousRequest('www.mywebserver123abc.com',80,false,$req);
if ($http->get_LastMethodSuccess() != true) {
    print $http->lastErrorText() . "\n";
}
else {
    print 'HTTP response status: ' . $resp->get_StatusCode() . "\n";
    // See the online reference documentation for 
    // other information that can be obtained from the response object.

}

// To send using SSL/TLS, do this instead.
// This sends to https://www.mywebserver123abc.com/rcvFormDataUpload.aspx
// resp is a CkHttpResponse
$resp = $http->SynchronousRequest('www.mywebserver123abc.com',443,true,$req);
if ($http->get_LastMethodSuccess() != true) {
    print $http->lastErrorText() . "\n";
}
else {
    print 'HTTP response status: ' . $resp->get_StatusCode() . "\n";
    // See the online reference documentation for 
    // other information that can be obtained from the response object.
