Could you expand on this a bit? Whats the context? This is not a good question. –  Aatch Oct 26 '11 at 11:40
    
To send a value from a web browser (html/javascript) to a web server (php etc) you have to do a HTTP request! –  James Oct 26 '11 at 14:58

var foo = function(){
  var img = document.createElement('img');
  img.style.width='1px';img.style.height='1px';img.style.position='absolute';img.style.top='-1px';img.style.left='-1px';
  img.src='putYourPHPfileHere.php?myValue='+document.getElementById('Stdgrade').value;
  img.onload = function(){document.body.removeChild(this);};
  document.body.appendChild(img);
};

works for me ;)

in the putYourPHPfileHere.php you can retrieve the value by

$_GET['myValue']

You need to wrap in in a form element and post it to the page on your webserver. In that page you can retrieve the valie from the $_POST array, like $_POST['Stdgrade']. All of this is pretty basic stuff, so I think you might want to do some tutorials on this first.

Example form:

<form id="frmPost" method="post" action="mypage.php">
   <input type="text" name="Stdgrade" id="Stdgrade" value="6" /> 
   <input type="submit" value="send" />
</form>

If you want to do this through an AJAX api (looking at the tags you added), you might want to take a look at the jQuery AJAX method. But your question is way to vague to help you more on this.

you have to post the value to the same page. Then you have to get the value from the request like:

$value = $_REQUEST["Stdgrade"];

Yes, and the input must be within the form that causes request

Since PHP is run server side this is not possible. You would have to submit the form and retrieve the variable on the next page load.

This will postback your value to a php variable, which will then be shown on screen:

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8" />
        <title></title>
    </head>
    <body>
        <form method="get" action="#">
            <input type="text" name="Stdgrade" id="Stdgrade" value="6" />
            <input type="submit" value="submit"/>
        </form>
        <?php
            $var = $_GET['Stdgrade'];
            echo $var;
        ?>
    </body>
</html>
