I'm trying to post avatar images from my website to pipedrive using PHP/Curl. The docs require a multipart/form-data encoding. I can't seem to get the actual file to post. I've tried several ways to send the file from various how-to's but every time pipedrive returns "no file attached". I've pasted my current attempt below, any ideas? Or perhaps just point me to an example that would work?
$ch = curl_init();
$timeout = 10;
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
curl_setopt($ch, CURLOPT_INFILESIZE, $params['filesize']);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER,
array('Content-Type:multipart/form-data')
);
$data = curl_exec($ch);
$params = array(
'id' => $PDid,
'file' => plugin_dir_path( dirname( __FILE__ )).'tmp/'.$filename,
'filesize' => filesize(plugin_dir_path( dirname( __FILE__ )).'tmp/'.$filename)
);
