$config->urls->root and $config->httpHost Empty

[MadHatter]

Hi,

I've tried printing the domain url but can't get ProcessWire to return anything. I can get it to work if I manually define the url in config.php but shouldn't this be detected automatically?

Any chance you are using these inside a function or module?

In that case you'd need: 

wire('config')->urls->root 

Do you have debug mode turned on? That should let you know that you have an undefined variable: $config

I'm just trying to echo it out in a template file. I'm just trying to get ProcessWire to print out the web address of the site (e.g. "http://www.example.com").

Well:

$config->urls->root will usually just give you "/"

$config->httpHost should give www.example.com

How are you defining the url in config.php ?

Is this an issue in your local testing environment, or on a live server?

The domain is listed in the $config->httpHosts array. Does the domain need to be speicified for it to be callable via $config->urls? I was under the impression that it was pulled automagically from $_SERVER environment variables.

Sorry, in a rush, but I think you are correct - I think it's coming from: $_SERVER['HTTP_HOST']

I wonder if Ryan should add a backup check for $_SERVER['SERVER_NAME'] if host return nothing.

Can you confirm what $_SERVER['HTTP_HOST'] is actually returning?

[MadHatter]

$_SERVER['HTTP_HOST'] is returning the web address I'm currently using.
