JS to PHP

[BelgainDSoul]

I'm totally clueless how to accomplish this: PHP keep complaining about the "}" or an unespected $end.

The script gets loaded externally by a *.php page constructed out of smaller scripts.

Main idea is to parse JavaScript Variables to PHP or vice-versa, popping up a hint with a variable source. ("test.pop" here.)

In the page the script gets called by :

onClick="pop(<? $X = "test"; ?>)"

The Script:

<script language="JavaScript" type="text/JavaScript">

// "testing" <? $X = "test"; ?> 

function pop(){

<?
$Path_X = "C:\wwwroot\";  // Set Base
$Path_EX = '.pop';               // Give extention
$Path_Whole = $Path_X . $X . $Path_EX;   // Construct
$string = require($Path_whole);        // Set stream from 'hint' file.
?>

alert('<? echo $string ?>');         // Open stream in alert()
}</script></head>

You're missing a semicolon after this line (in the PHP part):

alert('<? echo $string ?>');

Try that.

PHP runs on the server. Javascript runs on the client. They are completely different environments, and, usually, different computers.

The way to pass information from PHP to Javascript is to use PHP to generate a page containg valid Javascript.

Example:

<script language="JavaScript">
alert("<? echo $somephpvariable; ?>");
</script>

The way to pass information from Javascript to PHP is to request a new page from the server, passing the information back to the server in any of the standard ways: GET, POST, or a cookie.

Thanks for the replies.

I should be able to get it done with keeping in mind the client/server environment.
