Hi Guys,

I am trying to call the Javascript function declared at the top in my php area. However its not working. Can anyone tell me the reason for it. Everything else is working except for this part. Please help me.

<script type="text/javascript">

   function doDecryption()
                {
                document.write("Inside Javascript");
                var ct, key;
                
      ct = hex2s(<?php echo $myValue; ?>);
      document.write("Inside Javascript");
      document.write(ct);
     // key = hex2s(theForm.key.value);
     // theForm.plaintext.value = byteArrayToHex(rijndaelDecrypt(ct, key, "ECB"));


                }


</script>

Hi there, Have a look at this: This is just an example of how you can inter-mingle php and js.
The function is actually PHP, but what's contained inside of it is JS

<?php
	Redirect("page.html");
?>
 
/**
 * JavaScript Redirect Function - Redirects the user should the result data be empty
 * @param string $url the dynamic url to redirect to
 */
function Redirect($url) 
{ ?>
	<script type="text/javascript">
		window.location = "<?php echo $url ?>"
	</script>
<?php 
}

        {

            $query = mysql_query("select * from employee_details where id = '$userId'");
                if($row=mysql_fetch_assoc($query))
                    {
                        echo '<tr>';
                        foreach($row as $value)

        else if (($_SERVER['REQUEST_METHOD'] == 'POST') && ($_POST['key']))
            {

               $columname = "ciphertext";
               $tablename = "employee_details";

                     return @mysql_result($result, 0);
                }

                    $myValue = getField($columname,$tablename,$userId);

                    echo "$myValue";
                    doDecryptionPHP();   //call the php function
            }

function doDecryptionPHP()

    doDecryption();    

    function doDecryption()
    {
                document.write("Inside Javascript");
                var ct, key;
                
      ct = hex2s(<?php echo $myValue; ?>);
      document.write("Inside Javascript");
      document.write(ct);
     // key = hex2s(theForm.key.value);
     // theForm.plaintext.value = byteArrayToHex(rijndaelDecrypt(ct, key, "ECB"));
     }
</script>
<?php
}            
?>
</body>
</html>

Perhaps something like that? I have no idea if that will work, but have a play around with it and I'm sure you can get it to work!
