Proper way to get web_root

never mind this was just to problematic depending on peoples server configurations, so i just reverted back to the old way the plug-in was finding the base_path by default.

simple

if (array_key_exists('DOCUMENT_ROOT',$_ENV))
        {
            $base_path = $_ENV['DOCUMENT_ROOT'];
        }
        else
        {
            $base_path = $_SERVER['DOCUMENT_ROOT'];
        }

This seems to work fine for servers only reporting this in ENV OR _SERVER If anyone knows a more universal way let me know

Any reason you’re needing the web root instead of the folder that ExpressionEngine is being executed from?

Hi Derek what i am doing is building the absolute path to a image on the server based on webroot and the relative path supplied by the user. ./ works for me but i found allot of people have strange setups so ‘DOCUMENT_ROOT’ concatenated with user supplied relitive path seems to work more universally.

I don’t guess I’m really following on how that correlates to finding the web root, as ExpressionEngine and the user’s files could be anywhere. I’d give a specific recommendation for how to get it if I had a larger overall picture of what you’re doing, i.e. where the relative path is coming from, what types of files are being referenced (EE uploaded files? Themes specific to your add-on?), and whether this executes from the control panel or the user side.

Hi Derek,

For me, getimagesize() function needs to be a base server path in order to work (at least on my server).

On the other hand, my work servers do not care if the path is from the root.

Essentially, I am in the same boat as Lumis.

I like the posted solution though… I prefer writing it like this:

$base_path = (array_key_exists('DOCUMENT_ROOT', $_ENV)) ? $_ENV['DOCUMENT_ROOT'] : $_SERVER['DOCUMENT_ROOT']; // Server root path.

Anyone know how bullet proof that is?

Thanks, M

Lumis,

I noticed that in your image sizer plugin, you use this code:

$base_path = str_replace("\\", "/", $base_path);
$base_path = $FNS->remove_double_slashes($base_path);

Just out of curiosity, what are you doing here? Should I be concerned with extraneous slashes when setting up the root/base path?

Thanks! M

RIght, that still has no correlation to web root. If it’s an uploaded file, you will want to use the path from the database for that upload location.
