What I have done is use a form to set a hidden form element equal to a javascript value. Then I print out that form value in PHP.

To take a variable from PHP I use something like

document.value=<? print "$value"; ?>

Here you go the first is the HTML file you need, then there is a very simple php file to post to. You must first click the 'click here' then click submit.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<HTML>
<HEAD>
<TITLE>Untitled</TITLE>
<META NAME="GENERATOR" CONTENT="MAX's HTML Beauty++ ME">
<SCRIPT TYPE="text/javascript" LANGUAGE="JavaScript">
function test(apply) {
document.colorss.Form_Text_Decoration.value='test';
}
</SCRIPT>
</HEAD>

<BODY>

<a href="#" onclick="test();">Click Here</a>

<form method="post" name="colorss" action="css.php">
<input type="hidden" name="Form_Text_Decoration" size="10" maxlength="6">
<input type="submit" value="submit">
</form>

</BODY>
</HTML>

This is the PHP file.

<?
print "$Form_Text_Decoration";
?>

Thanks for the cool demonstration.

Just fooling around, I used the onClick handler on the submit button:

<form method="post" name="colorss" action="test.php">
<input type="hidden" name="Form_Text_Decoration" size="10" maxlength="6">
<input type="submit" value="submit" onClick="test();">
</form>

Wonder if it works with Netscape...
