How to include JavaScript into PHP to get 2 Variables ???

[sunbeam]

hello 2 all. im trying for the last couple of days to get 2 simple variables/data into the MySQL Database.

Short Description of the Project:

we developed a e-learning system for our students. each student has a unique username/password to view the modules he/she should view and nothing more. since we want to give them the opportunity to run these modules from home as well, we are trying to get the USERNAME/COMPUTERNAME as well, so the students, when they sign up for the modules, they can ONLY run the modules from the home PC.

We found a very nice JavaScript, that gives us the opportunity to get these 2 values, but we are not able to retrieve these values into PHP.

The JavaScript has as follow:


[code]
//~~Author~~. Curtis Riley
//~~Email_Address~~. [email protected]
//~~Comment~~.
//Gets the current user's name, domain, and PC name, then gets the global
//groups on the domain that the user is a member of, and then checks the
//local groups on the PC to see if the user is a member. All of the data is
//displayed as collected in an Internet Explorer window controled by the
//script.

//~~Script~~.
// WSH and ADSI demo program
// Gets global and local groups
// for the current user and machine
// and displays them in IE
// Requires: ADSI 2.5, WSH 2.0,
// Scripting 5.1, IE4
//Global ActiveX objects

If you run (save it as script.js or something else) the script, u get the desired information, the question ist how sould we place this script into a php page, to get these 2 values, when the student registers ??


any help would be appreciated

First I would like to say that ActiveXObject will only work in IE.

Ok I will give you a nice createRequestObject function, written by Ober.

[code]
function createRequestObject() {
    if (window.XMLHttpRequest) { // Mozilla, Safari, Opera...
        var xmlhttp = new XMLHttpRequest();
        if (xmlhttp.overrideMimeType)
xmlhttp.overrideMimeType('text/xml');
    }
else if (window.ActiveXObject) { // IE
        try {
            var xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
        } catch (e) {
            try {
                var xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
            } catch (e) {}
        }
    }

    if (!xmlhttp) {
        alert('Giving up :( Cannot create an XMLHTTP instance');
        return false;
    }
return xmlhttp;
}

var http = createRequestObject();
[/code]

Now say you are wanting to post something to a php script.. You could do something like this.

[code]
function sendRequest() {
    var field = document.getElementById('yourfield').value;
    http.open('POST', 'yourscript.php');
    http.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
    //send the field to the file
    http.send('field=' + field);
    //the handle request is a function that will handle the response from the php file
    http.onreadystatechange = handleRequest;
}

function handleRequest() {
    if (http.readyState == 4) {
      //the response from the php file
      var response = http.responseText;
      if (response == 'your error message') {
          alert('There was an error in sending the request');
      } else {
          alert('It worked');
      }
    }
}[/code]

Good Luck,
Tom

Tom, thank you for ur reply, hope im can get that thing to work , not so familiar in JS. Also, i know that ActiveXObject is only for IE, not very happy with that, but 4 now i have to accept that :(

I hope, that i can bother again, if i have problems

thank u in advance

[sunbeam]

ok, here it is how far i could get through by myself

[code]
var  gsUserName, gsComputerName;

function Get_ComputerName(){
  var  WshNetwork  = new ActiveXObject ("WScript.Network");
  return (WshNetwork.ComputerName);
}

function Get_UserName(){
  var  WshNetwork  = new ActiveXObject ("WScript.Network");
  return  (WshNetwork.UserName);
}
[/code]

so... in my opinion the 2 GET functions (Get_ComputerName and Get_UserName) should show the required data if they where called somewhere in the file, right ???

my question is, how can i put this code into a single php file, the 2 GET functions should somehow do what they sould do, and afterwards, how to put the results of the 2 GETs into a simple php variable, something like

[code]
<?php
$variable_UserName = gsUserName ;
$variable_ComputerName = gsComputerName ;
?>
[/code]

Not so simple with two runtimes....

...as i said, i know nothng about JS :(

i did a lite version of my first code

[code]
var  ie = new ActiveXObject ("InternetExplorer.Application");

var  gsUserName, gsComputerName;

BuildOutputWindow();
  gsUserName    = Get_UserName();
  gsComputerName = Get_ComputerName();
  ShowUserData();

function Get_ComputerName(){
  var  WshNetwork  = new ActiveXObject ("WScript.Network");
  return (WshNetwork.ComputerName);
}

function Get_UserName(){
  var  WshNetwork  = new ActiveXObject ("WScript.Network");
  return  (WshNetwork.UserName);
}

function BuildOutputWindow(){
  var  n = 0;
  var  s = "";

  ie.height      = 480;
  ie.width      = 640;
  ie.menubar    = false;
  ie.toolbar    = false;
  ie.statusbar  = false;
  ie.addressbar  = false;
  ie.resizable  = true;
  ie.navigate ("about:blank");

  while (ie.busy) {++n};

  ie.document.body.innerHTML = "Building Document..." + "<br>load time= " + n;
  ie.visible = true;
  s += '<p id="UserData_id">No user data</p>\n';
  ie.document.body.innerHTML = s;

}

function ShowStatus(sCurrStatus){
  ie.document.all.item("Status_id").innerHTML = sCurrStatus;
}

function ShowUserData(){
  var  s = ""
  s += '<table>\n';
  s += '<tr><td width="33%" align=center><u>User Name</u></td>';
  s += '<td align=center><u>Computer Name</u></td></tr>\n';
  s += '<tr><td align=center>' + gsUserName + '</td>';
  s += '<td align=center>' + gsComputerName + '</td></tr>';
  s += '</table>'
  ie.document.all.item("UserData_id").innerHTML = s;
}
[/code]

saved it, and double clicked it, a popup window came up and the requested info was there.

there must be a way to merge that script into a single php file , or not ?

i posted also a screenshot with the info i got from the js, when i doubleclicked it

You can have PHP write out JS code, but not vice-versa.
