Upload a PDF file to a potential

Hi,

I'm facing a problem with the uploadFile Method. The error i have is the error 4424.

I'm trying to upload a pdf directly from a server.

I hope that you can help me.

Here is my PHP code :

$content = '@devis/devis_100179';

$post=array("id"=>$recordId,"content"=>$content);

//================= start curl ===================

$ch = curl_init();

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

curl_setopt($ch,CURLOPT_URL,$url);

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_TIMEOUT, 30);

curl_setopt($ch, CURLOPT_POST, 1);

curl_setopt($ch,CURLOPT_POSTFIELDS,$post);

$result = curl_exec($ch);

curl_close($ch);

Thanks a lot for your help
