I wrote a WordPress widget for displaying some fuel prices in my sidebar. Now I want to let it update some fuel websites if the prices change. The following piece of code should log me in but it doesn’t work for whatever reason. I have no idea what’s going wrong

$ch = curl_init();

$options = array(
		CURLOPT_URL => 'http://www.clever-tanken.de/login.asp',
                CURLOPT_HEADER => false,
                CURLOPT_FOLLOWLOCATION => true,
   		CURLOPT_POST => 1,
   		CURLOPT_POSTFIELDS => "name=imtheuser&pass=my%3Apass"
                );

curl_setopt_array($ch, $options);
curl_exec($ch);
curl_close($ch);
