send from a file as if from a form

I have this code to send values to a file.

The values are entries received from a form, but cannot be sent directly from the form.

I need to send this data so it is received as if it were from the form, i.e., as in method=post form action.

What needs to be added?

<?php 
$siteUrl="http://receivingurl/receive.jsp";

$variablesToPost = array
(
	"first_name",
	"last_name"

$postData = array();

foreach($variablesToPost as $variable)
{
$postData[$variable]=urlencode($_REQUEST[$variable]);
}

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $siteUrl);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $postData);
curl_exec ($curl);
curl_close ($curl); 
?>

Code (markup):

 

try something like this

<? 
           
$_data_boundary = '----' . md5(uniqid(rand(), true));
$temp = array();
	foreach ($array as $key => $value)
	{
		$key = isset($parent_key) ? sprintf('%s[%s]', $parent_key, rawurlencode($key)) : rawurlencode($key);
		if (is_array($value))
			$temp = array_merge($temp, set_post_vars($value, $key));
		else
			$temp[$key] = urlencode($value);
	}
$array = $temp;
foreach ($array as $key => $value)
{
	$_post_body .= "--{$_data_boundary}\r\n";
	$_post_body .= "Content-Disposition: form-data; name=\"$key\"\r\n\r\n";
	$_post_body .= urldecode($value) . "\r\n";
}
unset($temp);
$temp = array();
foreach ($_FILES as $key => $value)
{
	$key = isset($parent_key) ? sprintf('%s[%s]', $parent_key, urlencode($key)) : urlencode($key);
	if (is_array($value))
	{
		$temp = array_merge_recursive($temp, set_post_files($value, $key));
	}
	else if (preg_match('#^([^\[\]]+)\[(name|type|tmp_name)\]#', $key, $m))
	{
		$temp[str_replace($m[0], $m[1], $key)][$m[2]] = $value;
	}
}
$array = $temp;
foreach ($array as $key => $file_info)
{
	$_post_body .= "--{$_data_boundary}\r\n";
	$_post_body .= "Content-Disposition: form-data; name=\"$key\"; filename=\"{$file_info['name']}\"\r\n";
	$_post_body .= 'Content-Type: ' . (empty($file_info['type']) ? 'application/octet-stream' : $file_info['type']) . "\r\n\r\n";

	if (is_readable($file_info['tmp_name']))
	{
		$handle = fopen($file_info['tmp_name'], 'rb');
		$_post_body .= fread($handle, filesize($file_info['tmp_name']));
		fclose($handle);
	}
	
	$_post_body .= "\r\n";
}

$_post_body       .= "--{$_data_boundary}--\r\n";
curl_setopt($curl, CURLOPT_POST, 1); 
curl_setopt($curl, CURLOPT_POSTFIELDS, $_post_body);
		
proxy_set_postdata($_post_body, $_socket);
$proxy_headers = array();
$proxy_headers[] = "Content-Type: multipart/form-data; boundary={$_data_boundary}";
$proxy_headers[] = "Content-Length: " . strlen($_post_body);
curl_setopt($curl, CURLOPT_HTTPHEADER, $proxy_headers);
}
 ?>

That additional code looked like it should achieve something, but I still could not get this to work.

Since curl apparently requires a load of code, I am now trying this simpler approach:

<?php
$Url="http://receivingurl.com/receive.jsp"; 

foreach ($_POST as $key => $value)
{ 
$url .="$key=" . urlencode($value) . "&";
} 
header ("Location: http://receivingurl.com/receive.jsp"); 
?>

Code (markup):

This looks like it should resend the values, but I get an error message indicating that something is missing:

I know the values get to the intermediate file. If I send direct from the form to the same url, that works.

Why won't this code work?

 

try this

<?php
$url="http://receivingurl.com/receive.jsp"; 

foreach ($_POST as $key => $value)
{ 
$url .="$key=" . urlencode($value) . "&";
} 
header ("Location: $url"); 
?>

PHP:

you didn't have the header command pointing to the variable $url but instead to a constant

 

Yes. I did header the wrong way because I got an "invalid url" error message when I did it the right way.

The url must have a "?" after it because the code is creating a query string:

<?php
$url="http://receivingurl.com/receive.jsp?";

foreach ($_POST as $key => $value)
{
$url .="$key=" . urlencode($value) . "&";
}
header ("Location: $url");
?>

Code (markup):

Now it all works.

 

If you have PHP 5, you can also use http_build_query().

header ("Location: $url". http_build_query($_POST));
