Update Close issue field with JIRA SOAP API

[SamJ]

I am trying to update a field of an issue using JIRA API and PHP.

<?php
set_time_limit(0);
session_start();
$soapClient = new SoapClient("http://jira.example.com/jira/rpc/soap/jirasoapservice-v2?wsdl");
$token = $soapClient->login('userId', 'passwd') or die('Username/Password is not correct!');
$data = array('fields'=>array('id'=>'customfield_11662','values'=>array('SDLCT-3')));
$soapClient->updateIssue($token,'SDLCT-3', $data)

SDLCT-32 is an CLOSED issue whose customfield_11662 field  is not being updated by the script.

But the script works fine for All the open, inprogress, reopened  issues.

Error

Fatal error:  Uncaught SoapFault exception: 
[soapenv:Server.userException] 
com.atlassian.jira.rpc.exception.RemoteValidationException: Fields not 
valid for issue: 
Errors: {}
Error Messages: [You do not have permission to edit issues in this

So can any one suggest me how to solve this error and update the field for closed issues?

Thanks in advance...

Your setup is such that you cannot edit closed issues.  You either need to remove that flag from the workflow (which will also allow edits in the UI) or re-open the issue to edit it, or add an "edit" style transition to the workflow for your script to use.

(Also, consider moving to the REST interface, as SOAP is deprecated and will be removed soon)
