[SOLVED] moving session cookie data to client cookie

[methano]

I know I'll probably get hammered for not understanding the header problem, but is there a simple way to get data from a MySQL search or from a session variable, into a client cookie?

 

The client cookie already has data in it and I want to change it.  I'd like to put the code on an include page, which is where I seem to get into trouble.  I've tried this with PHP code but would also consider using Javascript to read the session cookie, which also seems to be problematic.

PHP Sessions can only be read by PHP, client side code won't be able to access them directly. You can use Cookies instead which are accessible by PHP and JavaScript

Unfortunately, the data is coming from MySQL via PHP.  I'm trying to embed the javascript instructions to set the client side cookie within PHP and it doesn't seem to work.

 

I use:

 

<?php

$wholerxn = "smith";

echo "<script>function setCookie(\"wholerxn\",".$wholerxn.",5);</script>\n";

?>

 

where the javascript function is

 

function setCookie(c_name,value,expiredays)

{

var exdate=new Date();

exdate.setDate(exdate.getDate()+expiredays);

document.cookie=c_name+ "=" +escape(value)+

((expiredays==null) ? "" : ";expires="+exdate.toGMTString());

}

 

I've probably messes up the syntax.

I finally got the syntax:

 

echo "<script>setCookie('wholerxn','$wholerxn',5);</script>\n";

 

where:

 

function setCookie(c_name,value,expiredays)

{

var exdate=new Date();

exdate.setDate(exdate.getDate()+expiredays);

document.cookie=c_name+ "=" +escape(value)+

((expiredays==null) ? "" : ";expires="+exdate.toGMTString());

}

 

Thought I'd tried that already.

well...if the value is in PHP, you can just use PHP to set it:
