cURL and image upload field

[rednax]

I'm trying to write a script that will fill out a remote form that contains a few text fields and an image upload field. The text fields work fine, but I cannot for the life of me get the image upload to work...

 

Here is some sample code: (I've already connected with cURL and logged in to the form.)

 

// Copy thumbnail over and rename
$thumbLocation = "http://www.domain.com/thumbs/preview.jpg";

$name = "test";
$newLocation = "thumbs/".$name.".jpg";

if (!copy($thumbLocation, $newLocation)) {
    echo "failed to copy.\n";
}
$Location = "/usr/home/username/domains/domain.com/public_html/thumbs/".$name.".jpg";


$Fields = array('gallery_url' => $galleryURL, 'gallery_title' => $galleryTitle, 'newthumb' => $Location, 'save' => 'Insert');

   $o = "";
   foreach ($Fields as $key => $value)
   {
       $o .= urlencode($key). "=" .urlencode($value)."&";
   }
   
$Fields = substr($o,0,-1); // lose last &

// Now I have a query string [$Fields] to submit to the form

curl_setopt ($ch, CURLOPT_POST, 1);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $Fields);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 0);
$submitIt = curl_exec($ch);

 

I guess my question is... am I okay to supply the local file path as the value for the image upload field - or am I misunderstanding something? I've tried giving it just the relative path, absolute etc without luck?

You may need to post the binary data of the image to the script....no....maybe not...I'm not sure if there's an easy way to upload an image with cURL.
