CakePHP console gives error "Undefined index: HTTP_HOST"

Question

I have a setting in my APP/Config/config.php I have a line that defines the host:

define('SITE_URL','http://'.$_SERVER['HTTP_HOST']);

Whenever I run the cake console, I get the error:

Notice (8): Undefined index: HTTP_HOST [APP/Config/config.php, line 144]
Code Context
include - APP/Config/config.php, line 144

ShellDispatcher::run() - CORE/Cake/Console/ShellDispatcher.php, line 68

Why is this appearing and how can I solve this problem?

Answer 1

Its because you are running from console, (cakePHP uses PHP-CLI)

$_SERVER['HTTP_HOST']

its only filled when running from a browser (web server)

Answer 2

@Braian is right.

You could do the following in your config file:

if(php_sapi_name() === 'cli') { 
    define('SITE_URL','http://{DEFAULT HOST HERE};
} else {
    define('SITE_URL','http://'.$_SERVER['HTTP_HOST']);
}

Alternatively, you could query your database for a host setting of some sort - if your hosts are different based on the environment - and use Configure::write to set your config value before your console scripts main logic is run.
