PHP in JavaScript

I am trying to use a common onload clipboard effect to automatically clipboard the user's IP, but I am unsure how to use PHP in unison with JavaScript. Can anyone help me?

<script type="text/javascript" language="javascript">
function copy(text2copy) {
  if (window.clipboardData) {
    window.clipboardData.setData("Text",text2copy);
  } else {
    var flashcopier = 'flashcopier';
    if(!document.getElementById(flashcopier)) {
      var divholder = document.createElement('div');
      divholder.id = flashcopier;
      document.body.appendChild(divholder);
    }
    document.getElementById(flashcopier).innerHTML = '';
    var divinfo = '<embed src="_clipboard.swf" FlashVars="clipboard='+escape(text2copy)+'" width="0" height="0" type="application/x-shockwave-flash"></embed>';
    document.getElementById(flashcopier).innerHTML = divinfo;
  }
}

window.onload = snvc;

function snvc() {
copy("User's IP address would go here");
}
</script>

Code (markup):

 

replace:

copy("User's IP address would go here");

Code (markup):

with

copy("<?php echo $_SERVER['REMOTE_ADDR']; ?>");

PHP:

 

I think most browsers won't allow direct copying but that's indeed the code, except if you are using a proxy

check this http://www.hawkee.com/snippet/1358/

 

I did this before and it copies that actual code to the clipboard, not the IP.

Oh, okay... nevermind. Probably because I had the file as .htm and not .php...
Yeah, thanks for helping me realize that.


Another question, though. If I wanted to make it so that the IP copied when an input button was clicked, how would I do that?

 

that's a misleading script snippet.

it will indeed present you with the users real ip if they are connecting directly or through a non-elite proxy, but if they are connecting through an elite proxy, a phproxy, or CGI proxy, then you wont get their real ip because the elite proxy server filters out and does NOT pass on the 'HTTP_X_FORWARDED_FOR' value, so all you will get is the proxy servers ip.

something like this but it will only work in IE i believe :

<SCRIPT LANGUAGE="JavaScript">
function ClipBoard()
    {
        holdtext.innerText = copytext.innerText;
        Copied = holdtext.createTextRange();
        Copied.execCommand("Copy");
    }
</SCRIPT>

<SPAN ID="copytext">
<?php echo $_SERVER['REMOTE_ADDR'] ?>
</SPAN>
<TEXTAREA ID="holdtext" STYLE="display:none;">
</TEXTAREA>
<BUTTON onClick="ClipBoard();">Copy IP to Clipboard</BUTTON>
