Getting variables retrieved by javasript to php

[fo3]

I'm trying to get variables, that a javascript function retrieves, from another php file. Any ideas how to do this?

I have a file '../filename.php', which has javascript in it. In the script there is a function: "function searchvalues(archive_nr)"
When the function is accessed, it returns some variables, that depend on the archive_nr.
What code should be in the other php file, to get those variables?

in order to javascript to pass variables to PHP, the variables must either be put into a form and submitted via POST or GET or you can simply use javascript to call the other page with query string like this:

../filename.php?var1=value1&var2=value2

depending on which approach you use, you will find the variables defined in either $POST or $GET. if you use the query string approach i just typed, your filename.php code might look like this:

<?

echo "var1 = " . $_GET['var1'];
echo "var2 = " . $_GET['var2'];


?>
