Short answer: no.

Long answer:
Why would you want to hide data sent to your application? Any
half-baked hacker could sniff all the traffic between the browser and
the server or analyse your HTML code without any problem.
It seems to me that you want to implement security through obscurity,
which never works and is always a bad idea (from a security perspective
and a usability perspective).
You should always validate the data sent from the browser at
server-side, and implement your security checks at server-side as well.

You can simulate the click as a form submit, you can make a form with
hidden fields, and instead of the submit button you add a javascript
code in the link tag<a href='link.html '
onclick="this.s ubmit()">Submit Link</a>, you can pass the
variables using POST method!

Yes. If the client supports cookies, you can use session
variables. In the first script, you can write:

session_start() ;
$_SESSION['foo'] = 'bar';
echo '<a href="next.php" >Next Page</a>';

In the next.php, you can do:

session_start() ;
echo $_SESSION['foo'];

An alternative solution would be to output a hidden form
anywhere on the page and use JavaScript to submit it when
the user clicks on a hyperlink:

<form name="hiddenFor m" method="POST" action="next.ph p">
<input type="hidden" name="foo" value="bar">
</form>

<a href="#" onClick='docume nt."hiddenForm" .submit()'>Next Page</a>

Re: how to pass data to linked page ???

but if the javascript is not supported or diabled on client machine
then the above will not work and i am working on a site which is going
to be accessed by millions of people so may be there are many users on
whose computer the javascript is disabled or not supported.

if any other solution without using javascript then let me know

anyway thxs for your reply....
