PROCESS.PHP

<?php

$myFile = "testFile.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh, $mac);
fclose($fh);
?>

 

I manually created testFile.txt so ist does exist

 

ERRORS ARE:

missing } after property list
http://10.0.0.1/apps/mac/mac2.php
Line 50
which is 

                mac: macs.getMacAddressesJSON();

 

and a range for jquery.js (I presume that is normal as it is a straight download from their site and they are only warnings not errors)

 

thorpe thanks for all your help your #1

[canadabeeau]

So that is my current code (thanks to you thorpe)

[trq]

Your declaring macs twice for starters. This will break things.

 

All this embbeding code? Where is it within your document?

 

You might want to simply try sending a simple string via ajax so we can at least eliminate that as a problem.

 

[canadabeeau]

Here is my simpler test code:

mac9.php

<script type="text/javascript" src="jquery-1.3.2.js"></script>
<script type="text/javascript">
       var macs = {
       getMacAddressesJSON : function() {
            var mac_string = "aaaaaaaaaaaaaaa";
            return mac_string
        }
   }

$(document).ready(function() {
   $.ajax({
       type: "POST",
       url: "process.php",
      dataType: "json",
       data: {
          'mac': macs.getMacAddressesJSON()
       }
     });
});
</script>

 

process.php

<?php
$mac = $_POST['mac'];
$myFile = "testFile.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
fwrite($fh, $mac);
fclose($fh);
?>

The code in the above post after somemodification now works :-) Now to get the other to work

[canadabeeau]

IT WORKS :-)

Thanks a billion thorpe, I dont know what I did but I (thanks to you) got it working, had to remove some of your lines of code i.e.

      success: function(d) {
         console.log(d)
      }

 

which seemed to make it work with some other stuff

 

So thanks a million, this is now sorted, finally :-)

[trq]

console.log() is simply there to aid in the debugging. Glad its working.

[canadabeeau]

as I said, thanks so much for all of your help thorpe, I really appreciate it

[canadabeeau]

Okay now I dont know why I am getting this error

document.macaddressapplet.setSep is not a function
http://10.0.0.1/apps/mac/index.php
Line 33

which is

           document.macaddressapplet.setSep( ":" );

[canadabeeau]

SOLVED again

[canadabeeau]

okay now another problem with it,

If i visit mysite.com it will not display the MAC but if I first visit mysite.com/apps/mac/index.php then go back to mysite.com the mac works

any thoughts on this.

 

from mysite.com/index.php I call it like this

<?php
$require_once = 'apps/mac/index.php';
require_once($require_once);
?>

in the body of the page <body>

[trq]

You need to post your current code.

[trq]

You need to think about the process. You have a page that echos an unset $_SESSION variable when it is executed. Once this script is executed it gets sent to the client. Once on the client you have some javascript which executes and makes another request back to the server and sets the $_SESSION variable you attempted to echo within the last request.

 

Thats it, the whole process.

 

The only way the page which is still sitting on the client can get to echo this $_SESSION variable is if you refresh it and make another request or to let Javascript update the current page.

 

If all you want to do is display a user mac address why are you sending it back to the server just to try and retrieve it again when it already exists on the client?

[canadabeeau]

It is going to a logging database and a range of other stuff happens to it

[canadabeeau]

If I refresh my page the MAC still does not come up?!?!?!?

[trq]

Try debugging your code then.

[canadabeeau]

found a/the errror

document.macaddressapplet.setSep is not a function
http://10.0.0.1/
Line 43

 

which is

           document.macaddressapplet.setSep( ":" );

 

why would I get this? This is the code required from the mac/index.php which works well by itself

 

Actually the error only disappears after two refreshes (at least on apps/mac/index.php) so why would I get it?

[canadabeeau]

I find it  interesting how this error is fixed after refresh but not fixed after refresh of the main index.php

[trq]

No doubt your logic is screwed up somewhere. Its likely that your embed tags need to actually go within your actual document somewhere. hence attaching it to the document object.

 

I'm not real sure as I haven't and wouldn't use embed tags. They are not part of xhtml, and are only officially supported in the brand new html5.

[canadabeeau]

How do you suggest I get the .jar in then or the .java???

[canadabeeau]

This is starting to really bug me, I have no idea why this only works when I got the the real location not the page which is requiring it, and if I got to the actual page I need to do a refesh about 2 time for it to work. Any ideas?
