Thread: File Upload with libcurl

Using VC++6 on XP, I am trying to upload a small jpeg file to a script that looks like:

PHP Code:

<form method="post" enctype="multipart/form-data" action="upload.php">

        File: <input type="file" name="file" size="40"> <br>
        Name: <input type="text" name="name" size="40"> <br>
        <input type="submit" value="send" name="submit"> <br>

</form> 


The code I am made is this:

Code:

#include <curl.h>
#include <stdio.h>

int main(int argc, char *argv[])
{
	CURL *curl;
	CURLcode res;

	HttpPost* post =	NULL;
	HttpPost* last =	NULL;

	curl = curl_easy_init();
	if(curl)
	{
		curl_formadd(&post, &last, 
			CURLFORM_COPYNAME, "file",
			CURLFORM_FILE, "C:\\rect.jpg",
			CURLFORM_END);

		curl_formadd(&post, &last, 
			CURLFORM_COPYNAME, "name",
			CURLFORM_FILE, "rect.jpg",
			CURLFORM_END);

		curl_easy_setopt(curl, CURLOPT_URL, "http://zxcvbn.t35.com/test.php");
		curl_easy_setopt(curl, CURLOPT_HTTPPOST, post);

		res = curl_easy_perform(curl);
		if(res)
		{
			printf("curl_easy_perform failed: %d\n", res);
		}
		curl_formfree(post);
	}
	else
		printf("curl_easy_init failed\n");

	return 0;
}

And I am getting the error:

curl_easy_perform failed: 7

Maybe?
CURLE_COULDNT_CONNECT, /* 7 */

Sorry I forgot to check error codes, and I had forgotton to give the program priveledges and was on a limited account. I have now also changed it from C:\\rect.jpg to rect.jpg and had to move the executable because I was getting a read error (26). Now, I'm getting back from my web script: No file specified. This is the script;

PHP Code:

<?php

if($_FILES['file']['name'] != "")
{
    copy ($_FILES['file']['tmp_name'], "/uploads" . $_FILES['file']['name'])
    or die ("Could not copy file");
}
else
{ 
    die( "No file specified" ); 
}

?>

Are you using ethereal to watch
a) what your browser does successfully when it uploads
b) what your program fails to do

Problem was with my script working with the host mostly. Thanks for the help. Final code:

Code:

	curl = curl_easy_init();
	if(curl)
	{
		curl_formadd(&post, &last, 
			CURLFORM_COPYNAME, "file",
			CURLFORM_FILE, "C:\\rect.jpg",
			CURLFORM_END);

		curl_formadd(&post, &last, 
			CURLFORM_COPYNAME, "name",
			CURLFORM_COPYCONTENTS, "rect",
			CURLFORM_END);

		curl_easy_setopt(curl, CURLOPT_URL, "http://blah.com/upload.php");
		curl_easy_setopt(curl, CURLOPT_HTTPPOST, post);

		res = curl_easy_perform(curl);
		if(res)
		{
			return 0;
		}
		
		curl_formfree(post);
	}
	else 
	{
		return 0;
	}

	curl_easy_cleanup(curl);
