Get signature count

[Tom Vile]

Just looking for some php code to get the signature count of my petition.

Any help will be appreciated.

Anyone have a suggestion?

This PHP function takes 1 Change.org petition url and returns its signature count. Be sure to replace API_KEY with your api key.

// get signatures for a Change.org petition
function getChangePetitionSignatureCount($url){
 $CHANGE_API_KEY = 'API_KEY';
 $CHANGE_REQUEST_URL = 'https://api.change.org/v1/petitions/get_id';
 $parameters = array(
 'api_key' => $CHANGE_API_KEY,
 'petition_url' => $url
 );
 $query_string = http_build_query($parameters);
 $final_request_url = "$CHANGE_REQUEST_URL?$query_string";
 $response = file_get_contents($final_request_url);
 $json_response = json_decode($response, true);
 $petition_id = $json_response['petition_id'];
 //now get the petition details for signature count
 $CHANGE_REQUEST_URL = 'https://api.change.org/v1/petitions';
 $parameters = array(
 'api_key' => $CHANGE_API_KEY,
 'petition_ids' => $petition_id
 );
 $query_string = http_build_query($parameters);
 $final_request_url = "$CHANGE_REQUEST_URL?$query_string";
 $response = file_get_contents($final_request_url);
 $json_response = json_decode($response, true);
 $petition = $json_response['petitions'][0];
 $sig_count = $petition['signature_count'];
 //var_dump($json_response);
 return $sig_count;
}
