get web root

[jwk811]

i use a php function to get "http://www.domain.com"

 

when i go to my javascript file and try to go <?php echo WEB_ROOT; ?> it doesnt work. so is there a way to use php in a javascript

 

if not is there a way to get the website with js?

[jwk811]

nevermind it doesnt even work when i put the full url in.

 

its an ajax thing

 

xmlhttp.open("GET","lib/getMessage.php",true);

 

that works for only the front page. but if i go to a different folder it wont work because the url changes.

 

if i put

xmlhttp.open("GET","http://www.domain.com/lib/getMessage.php",true);

that doesnt work tho!

 

why??? i know this is more ajax/js now but please help

Try this:

 

<?php echo $_SERVER['DOCUMENT_ROOT'];?>

Your problem could be that you're accessing the web page without the www. and the AJAX request includes the www In that case you should either force www or no www or do something like this:

 

xmlhttp.open("GET","http://" + location.host + "/lib/getMessage.php",true);
