PHP cURL isn't storing the session cookie... How to fix this?

Question

Hi all, I am making a class to comunicate with our company API... I'm using curl to post data and retrieve the response in json. In the last part of the code (after the class), i log the user into the server (it gives true), but when i try to connect again with curl, he says that i'm not logged! I've done a google search already and added the curl_setopt($ch,CURLOPT_COOKIE,$this->Session_Cookie); line.

Can anybody give me a light on this?

Thanks in advance ;)

if(!class_exists("Microdual")) {
 class Microdual{

  // No caso de a sessão não estar iniciada, iniciar aqui a sessão

Answer 1

The CURLOPT_COOKIE option is for sending a particular cookie using CURL. The options you are looking for are CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR, which specify a file to save and load cookie from.

So you'll have to do something like this:

curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookies.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookies.txt');
