RopeADope Posted January 13, 2011 Share Posted January 13, 2011 Hi all. Working on a nav system using the document_root variable. I can't figure out why the links won't execute when I click them. When I mouse over a link, it shows the correct URL, but nothing happens when I click the links. The browser remains on the same page. The page <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <title>vCTO-Home</title> <link rel="stylesheet" type="text/css" href="css/style.css" media="screen" /> <?php include($_SERVER['DOCUMENT_ROOT'] . '/php/var.php');?> </head> <body> <?php include($_SERVER['DOCUMENT_ROOT'] . "/php/t1.php");?> </body> </html> t1.php <div class="tier"> <a href="<?php echo $docroot;?>/index.php">Home</a> <a href="<?php echo $docroot;?>/demand_management.php">Demand Management</a> <a href="<?php echo $docroot;?>/engineering.php">Engineering</a> <a href="<?php echo $docroot;?>/steady_state.php">Steady State</a> <a href="<?php echo $docroot;?>/communications.php">Communications</a> <a href="<?php echo $docroot;?>/business_management.php">Business Management</a> <a href="<?php echo $docroot;?>/risk_management.php">Risk Management</a> <a href="<?php echo $docroot;?>/other.php">Other</a> </div> var.php <?php $docroot=$_SERVER['DOCUMENT_ROOT']; ?> Quote Link to comment Share on other sites More sharing options...
PFMaBiSmAd Posted January 13, 2011 Share Posted January 13, 2011 $_SERVER['DOCUMENT_ROOT'] is a file system path. It only has meaning on the server to the file system and php statements that use file system paths. It is not a URL. A URL is - http://some_domain.com/some_path/some_file.ext Quote Link to comment Share on other sites More sharing options...
RopeADope Posted January 13, 2011 Author Share Posted January 13, 2011 So how do I go about accomplishing what I'm trying to do? Is there a way to set a document_root-like path to use in URLs? Quote Link to comment Share on other sites More sharing options...
PFMaBiSmAd Posted January 13, 2011 Share Posted January 13, 2011 A leading slash / on a URL, makes it a domain-root relative URL, which most browsers support. They take the http://some_domain.com of the current page and append the domain-root relative URL to it. If you want to form a fully qualified/absolute URL, you can either setup a configuration variable/constant to hold your domain or you can use $_SERVER['HTTP_HOST'] to get it at runtime to make the - http://some_domain.com/some_path/some_file.ext URL.

RopeADope Posted January 17, 2011 Author Share Posted January 17, 2011 So I thought I had this figured out but I've run into another problem. I tried using a leading "/" which worked initially, but I've found that with documents that are in directories, I can only load files in parent folders by using "../". I also tried using $_SERVER['HTTP_HOST'] instead of the leading slash but that hasn't worked. Quote Link to comment Share on other sites More sharing options...
PFMaBiSmAd Posted January 17, 2011 Share Posted January 17, 2011 You would need to post an example of what you are doing, because I don't think it has anything to do with making links in a navigation menu. Quote Link to comment Share on other sites More sharing options...

PFMaBiSmAd Posted January 17, 2011 Share Posted January 17, 2011 Navigation links deal with URLs that the browser requests. Php include statements deal with file system paths that php uses to open and read a file. Links and include statements don't have anything to do with each other. You WOULD use $_SERVER['DOCUMENT_ROOT'] to form an absolute file system path to use in an include statement. A leading / on a file system path refers to the root of the current disk drive.
