Send 2 Different Content Types in 1 Http Request - How?

    What I'm trying to do is send both an image and text on one http request. I've tried multipart/mixed using boundaries.

    
ob_start();
header('Content-Type: multipart/mixed; boundary=unique-boundary-1');
header('--unique-boundary-1');
$filename = 'a.jpg';
header("Content-Type: image/jpeg", false);
$im = imagecreatefromjpeg($filename);
imagejpeg($im);
imagedestroy($im);

header('--unique-boundary-1');
header('Content-Type: text/html', false);

echo <<<YYY
<html><body>
<center>Hello - This Mime part should display while, or following the
file Download</center>
</body></html>
YYY;
header('--unique-boundary-1--');
ob_end_flush();
    Code (markup):
    Which doesn't work (in FF/IE/OP). Instead of getting the image displayed with text, I get the image file content because the Content-Type: text/html seems to over write the image content type header.

    I know it can be done with two http requests, but looking to do it from an href link. Please note, this is not for an email client, just a regular browser.

    Can it be done?

    Any help is appreciated.

    Have you read about the HTTP Accept field? I'm not sure but I think maybe a special parameter has to be sent in order for the client to receive multipart content. I'm not sure what the parameter is, though.
    Here's what my FF is sending on a regular html request:

    Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5


    Is that good enough to accept multipart content? I don't know, but something to investigate.

    If this is the source of the problem then it's a client side issue and there probably isn't a way around it.

    Thanks for the suggestion, looked into it and tested. Unfortunately for me it didn't work.

    Here is simple script....


    look at the $form array (); to understand how to set the values


    
<?php

function send_post ( $host, $form_data, &$code, &$string )
{
	$data = '';

	$part = parse_url ( $host );

	if ( empty ( $part['path'] ) )
	{
		$part['path'] = '/';
	}


	if ( ( $io = fsockopen ( $part['host'], 80, $code, $string, 5 ) ) !== false )
	{
		$temp = "--_" . md5 ( uniqid ( microtime () ) );

		$send  = "POST " . $part['path'] . " HTTP/1.1\r\n";
		$send .= "Host: $part['scheme'] . "://" . $part['host'] . "\r\n";
		$send .= "Referer: " . $part['scheme'] . "://" . $part['host'] . $part['path'] . "\r\n";
		$send .= "User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT)\r\n";
		$send .= "Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,video/x-mng,image/png,mage/jpeg,image/gif;q=0.2,text/css,*/*;q=0.1\r\n";
		$send .= "Accept-Encoding: gzip, deflate, compress;q=0.9\r\n";
		$send .= "Accept-Language: en-us, en;q=0.50\r\n";
		$send .= "Content-Type: multipart/form-data; boundary=" . $temp . "\r\n";

		foreach ($form_data AS $k => $v )
		{
			if ( $v['file'] )
			{
				$data .= "--" . $temp . "\r\n";
				$data .= "Content-Disposition: form-data; name=\"" . $v['input'] . "\"; filename=\"" . $v['name'] . "\"\r\n";
				$data .= "Content-Type: " . $v['mime'] . "\r\n";
				$data .= "Content-Transfer-Encoding: base64\r\n\r\n";
				$data .= chunk_split ( base64_encode ( readfile ( $v['path'] ) ) ) . "\r\n";
			}
			else
			{
				$data .= "--" . $temp . "\r\n";
				$data .= "Content-Disposition: form-data; name=\"" . $v['input'] . "\"\r\n\r\n";
				$data .= $v['value'] . "\r\n";
			}
		}

		$data .= "--" . $temp . "--\r\n";

		$send .= "Content-Length: " . strlen ( $data ) . "\r\n\r\n";
		$send .= $data;

		$data = '';

		fputs ( $io, $send );

		unset ( $form_data, $k, $send, $temp, $v );

		while ( ! feof ( $io ) )
		{
			$data .= fgets ( $io, 4096 );
		}

		fclose ( $io );

		unset ( $io );
	}
	else
	{
		$data = false;
	}

	unset ( $part );

	return $data;
}

// uri, to post data to

$uri = 'http://localhost/upload.php';

// error code container

$code = 0;

// error string container

$string = '';

// the form data array

$form = array ( 
		/* input type text */

		0 => array ( 
				'file' => false, 
				'name' => '', 
				'mime' => '', 
				'path' => '', 
				'input' => 'name', 
				'value' => 'printf'
			),

		/* input type text */

		1 => array ( 
				'file' => false, /* this is not a file input */
				'name' => '', 
				'path' => '', 
				'mime' => '', 
				'input' => 'zipcode', /* the name of the form input */
				'value' => '02112' /* the value of the form input */
			),

		/* input type file */

		2 => array ( 
				'file' => true, /* this is a file input */
				'name' => '28-funny-warning.jpg', /* the file you are posting */
				'path' => 'f:/www/docs/28-funny-warning.jpg', /* the local system path to file */
				'mime' => 'image/jpeg', /* the file mime type */
				'input' => 'upload', /* the name of the form input */
				'value' => '' /* the value of the form input (always empty for file inputs) */
			)
		);


/* run it */

$out = send_post ( $url, $form, $code, $string );

if ( is_bool ( $out ) )
{
	echo "Error: (" . $code . "), " . $string . "\r\n";
}
else
{
	echo nl2br ( $out );
}

    thanks dataman, will give it a go, since my initial approach of using multipart just won't work across all browsers, especially IE.
