Passing JS to PHP

[canadabeeau]

So I have the following

<?php
getdetails(?><script type="text/javascript">document.write(jsvariable)</script><?php );?>

 

The idea is that the getdetails() will process the JS output rather than doing mysite.com?data=jsoutput as I REALLY REALLY RALLY dont want urls like that. So why cant I get it to work, I think I have a syntax problem with opening and closing the getdetails()

 

Any help appreciated

As stated in the last post about this, its not going to happen unless you use a GET, Form or AJAX..

Sorry to be the bearer of bad news..

[canadabeeau]

okay I remember you mentioning AJAX how can I do this in AJAX.

And your not the bearer of bad news just the person snapping me into reality

Syntax problems are the least of your worries. You seem to also have a complete misunderstanding of client / server relationships and where php and Javascript fit in. PHP is executed on the server long before it is sent to the client, while Javascript is sent to the client and then executed. They are literally worlds apart.

Javascript can be run on the server just fine...

Can you explain in detail what your trying to do?

No kidding. But it doesn't contain a document object.

 

I'm sure the OP doesn't really need to be confused further by being made aware.

[canadabeeau]

Okay I need to pass the output of the JS which can ONLY be done in JS to a PHP variable, now I don't want to use (or cant) use forms or the URL method, so how can I, all suggestions welcome

 

PS I understand PHP is server side and JS is client side, nevertheless I still need to do what I am after

Here's your AJAX. http://www.w3schools.com/Ajax/Default.Asp It's a round about way of doing it, but it's the only other way.

As far as I can tell, he is only using document to output things. I have never used any of the SSJS implementations, but I'm sure they support basic things like outputting to stdout.

 

Depending on what kind of JS he wants to execute, I don't see why he couldn't use something like exec to execute it on the server with an SSJS implementation.

Could also use this simple js interpreter (j4p5) written in php.

 

Okay I need to pass the output of the JS which can ONLY be done in JS

 

What does the js do?

[canadabeeau]

Here is the JS

    <script type="text/javascript">
        var macs = {
            getMacAddress : function()
            {
                document.macaddressapplet.setSep( "-" );
                alert( "Mac Address = " + document.macaddressapplet.getMacAddress() );
			document.write(mac_string);
            },

            getMacAddressesJSON : function()
            {
                document.macaddressapplet.setSep( ":" );
                document.macaddressapplet.setFormat( "%02x" );
                var macs = eval( String( document.macaddressapplet.getMacAddressesJSON() ) );
                var mac_string = "";
                for( var idx = 0; idx < macs.length; idx ++ )
                    mac_string += "\t" + macs[ idx ] + "\n ";
			document.write(mac_string);
            }
        }
    </script>

 

Which is thanks to a Java Applet for getting MAC address, so any ideas no that you know the code

 

[canadabeeau]

So AJAX is the way but anyone done it before and can tell me where to start never done AJAX before

[trq]

Yep, you'll need to use ajax to send your data back to the server.

[canadabeeau]

Okay so after reading all the posts I understand I will need to use AJAX to send the JS variable back to the server to be part of the PHP function (variable), but as a person nver done AJAX before can someone point me in the correct direction please

[trq]

Take a look at jQuery's library, it makes ajax simple.

 

For example...

 

$.ajax({
  type: "POST",
  url: "http://yoursite/process.php",
  data: {
    'mac': mac_string
  }
});

 

would be enough to send the mac_string data back to process.php on your site. Within process.php it would show up within $_POST['mac'].

[canadabeeau]

okay thanks thorpe

[Daniel0]

Wouldn't it be smarter making the Java applet sending the mac address to your server?

[canadabeeau]

Um... how?

[canadabeeau]

Here is the file

 

Its not really a .txt its a .java only way I could post though

Rhodry, my previous post included a link to a tutorial on how to use AJAX. Here's the link again

[canadabeeau]

Garethp I got your link, just have no idea where to start with it :-)

 

Maybe you can help me a bit more with that

[canadabeeau]

$.ajax({  type: "POST",  url: "http://yoursite/process.php",  data: {    'mac': mac_string  }});

 

Do I have to run this code or just

<?php $.ajax({  type: "POST",  url: "http://yoursite/process.php",  data: {    'mac': mac_string  }});?>

[canadabeeau]

I am really not sure how to proceed with this AJAX

[canadabeeau]

If I can get this data passed back to the server that will be the end of this thread for good :-)
