I am creating an ecommerce application, and wanted to send a variable
that would invoke a function to increment a particular item in the
shopping cart. If I use a querystring, I'm know that some user will get
upset once they hit reload, and inadvertantly add another item to the

I wanted to do this with text instead of a form button or image, and I
was wondering if it were possible.

Here is an example using JavaScript. I do not want to use JavaScript.
 From php-general:

<a href="javascript:setvars('var1value', 'var2value')">click here to go
next page</a>

<script language="JavaScript">
  function setvars(var1, var2)
    df = document.dataform;
    df.var1.value = var1;
    df.var2.value = var2;
<form name="dataform" action="page2.php" method="post">
<input type='hidden' name='var1'>
<input type='hidden' name='var2'>
