This is a PHP library for interacting with Inkdit. Right now it focusses on using hosted signing pages.
When the user does something that requires a contract to be signed, you construct a URL that contains the information you want to pass through to the contract.
$offer_url = '...'; // obtained from your contract page
$private_key = '...'; // obtained from your contract page
$url = inkdit_offer_url($offer_url,
$private_key,
array('email' => 'earl@example.org', 'redirect' => 'http://example.org/'),
array('contract-input-1' => 'St. Louis'));
The user gets sent to $url. They sign the contract. Inkdit redirects
them to the URL given as the 'redirect' parameter, and appends a query
string.
$query_string = $_SERVER['QUERY_STRING'];
$result = inkdit_verify_signing($query_string, $private_key);
// if the signing could not be validated, $result will be false.
//
// if the signing was validated, $result will be an array containing:
// contract_id: the id of the newly created contract
// contract_url: the URL of the newly created contract
// signed_at: the date and time that the contract was signed.
// ensure that the signing was created recently (PHP 5.3+)
$t = DateTime::createFromFormat(DateTime::ISO8601, $result['signed_at']);
if((time() - $t->getTimestamp()) > 300)
throw new Exception('This signing was created more than 5 minutes ago!');
At this point, the signing has been validated, you know that the contract has been signed, and the user can continue with your workflow.
