Non–Virginia residents who have recently received a card at the Library may send an email request with their full name and library card barcode number to <a href="mailto:refdesk@lva.virginia.gov" style="color:yellow">refdesk@lva.virginia.gov</a>. Within two to three business days, we will extend your card to expire on June 4, 2020. Otherwise, you can renew in–person at your next visit.

Non–Virginia residents who have recently received a card at the Library may send an email request with their full name and library card barcode number to <a href="mailto:refdesk@lva.virginia.gov" style="color:yellow">refdesk@lva.virginia.gov</a>. Within two to three business days, we will extend your card to expire on June 4, 2020. Otherwise, you can renew in–person at your next visit. We do not offer online renewal for non-Virginia residents.

So on line 191, you should create an if statement that checks if $api_result == null.

if ($api_result != null ) {
  $api_result = addEmail($api_result, $data['email']);
  $api_result = addPassword($api_result, $data['password']);
  $api_result = updateExpiryDate($api_result, 1);
  $api_result = $alma_api->update_user(json_encode($api_result), $data['previous_identifier']);
}
else {
  $api_result = array("You're not currently a library patron! Please <a href='http://www.lva.virginia.gov/register/'>create a new library account!</a>");
}

We'll assume that if the request is returning null, then the user doesn't exist.

I also don't know if the error codes will let you put in a link, but they should?
