javascript variables ---> PHP

[chops]

Any way to pass a js variable to PHP without reloading the page?...here is the js variable: var current_url = document.location ......I would like to be able to somehow convert that into a PHP variable.

If this is not possible....is there a variable I can call in PHP that will give me the entire URL....like $PHP_SELF?

I don't think that there is anyway to do this with javascript without reloading.

However, you could contuct it with something like
"http://".$HTTP_SERVER_VAR["SERVER_NAME"].$PHP_SELF

or

"http://".$HTTP_SERVER_VAR["SERVER_NAME"].HTTP_SERVER_VARS["REQUEST_URI"]

or
"http://".$HTTP_SERVER_VAR["SERVER_NAME"].HTTP_SERVER_VARS["SCRIPT_NAME"]

(i have never actually done this, but all of the above look like they will prduce the desired results)

calling phpinfo() will produce a list of variables that you can use.

none of those lines above produced any vars......

sorry,

the ones i gave you before had some syntax errors... these worked on my server (running apache)

echo ("http://".$HTTP_SERVER_VARS['SERVER_NAME'] . $PHP_SELF."<br>");
echo ("http://".$HTTP_SERVER_VARS['SERVER_NAME'] . $HTTP_SERVER_VARS['REQUEST_URI']."<br>");
echo ("http://".$HTTP_SERVER_VARS['SERVER_NAME'] . $HTTP_SERVER_VARS['SCRIPT_NAME']."<br>");

the differences: the variable is $HTTP_SERVER_VARS not $HTTP_SERVER_VAR

hope this helps,
