How to use SCORM API to retrieve data?

I am developing a simple LMS for medical trainees. So far i have developed a PHP LMS. For the content i have prepared a SCORM course with quizzes created with Articulate Storyline software. To communicate with SCORM and to retrieve quiz result i tried to implement SCORM API.

this is my Run time environment file

<html>
<head>

<title>VS SCORM - RTE Frameset</title>
<!-- Rev 1.0 - Sunday, May 31, 2009 -->

</head>
<frameset 
  frameborder="0" framespacing="0" 
  border="0" rows="0,*" cols="*" >
    <frame src="api.html" name="API" noresize></frame>
    <frame src="/packadge/JStest/story.html" name="course"></frame>
</frameset>
</html>

this is the api.html

<html>
<head>

<title>VS SCORM - RTE API</title>

<script language="javascript">

var debug = true;

// ------------------------------------------
//   SCORM RTE Functions - Initialization
// ------------------------------------------
function LMSInitialize(dummyString) { 
  if (debug) { alert('*** LMSInitialize ***'); }
  return "true";
}

// ------------------------------------------
//   SCORM RTE Functions - Getting and Setting Values
// ------------------------------------------
function LMSGetValue(varname) {
  if (debug) { 
    alert('*** LMSGetValue varname='+varname
                          +' varvalue=value ***');
  }
  return "value";
}

function LMSSetValue(varname,varvalue) {
  if (debug) { 
    alert('*** LMSSetValue varname='+varname
                          +' varvalue='+varvalue+' ***');
  }
  return "true";
}

function LMSCommit(dummyString) {
  if (debug) { alert('*** LMSCommit ***'); }
  return "true";
}

// ------------------------------------------
//   SCORM RTE Functions - Closing The Session
// ------------------------------------------
function LMSFinish(dummyString) {
  if (debug) { alert('*** LMSFinish ***'); }
  return "true";
}

// ------------------------------------------
//   SCORM RTE Functions - Error Handling
// ------------------------------------------
function LMSGetLastError() {
  if (debug) { alert('*** LMSGetLastError ***'); }
  return 0;
}

function LMSGetDiagnostic(errorCode) {
  if (debug) { 
    alert('*** LMSGetDiagnostic errorCode='+errorCode+' ***');
  }
  return "diagnostic string";
}

function LMSGetErrorString(errorCode) {
  if (debug) { 
    alert('*** LMSGetErrorString errorCode='+errorCode+' ***'); 
  }
  return "error string";
}

</script>

</head>
<body>

<p> 

</body>
</html>

but I don't see these functions are being triggered at the initiation of the SCORM project.

how to get Quiz result and alert it? (my idea is if I can do so, I will be able to send that results via ajax post to the sever)

In order for any course to find the API you need to declare window.API and the API itself contains all those LMSxxxxxxx() functions.

For example:

var SCORM = {}; // Create blank object

// ------------------------------------------
//   SCORM RTE Functions - Initialization
// ------------------------------------------
SCORM.LMSInitialize = function(dummyString) { 
  if (debug) { alert('*** LMSInitialize ***'); }
  return "true";
}

// ------------------------------------------
//   SCORM RTE Functions - Getting and Setting Values
// ------------------------------------------
SCORM.LMSGetValue = function(varname) {
  if (debug) { 
    alert('*** LMSGetValue varname='+varname
                      +' varvalue=value ***');
  }
  return "value";
}

// repeat for other LMSxxxxx() functions then assign to window.API

window.API = SCORM;
