Question

Today I wanted to write a simple php script, but I got some annoying errors.
I just simply include the config.php file and try to access the root_path variable without success. There are also 2 other warnings that only show when I include the config.php file.

The files are running on the newest xampp.

smarty_setup.php :

<?php
require('config.php');
require($root_path . '/libs/Smarty.class.php');

class FileHosting extends Smarty {

   function __construct()
   {
        parent::__construct();

        $this->setTemplateDir($root_path . '/templates/');
        $this->setCompileDir($root_path . '/templates_c/');
        $this->setConfigDir($root_path . '/configs/');
        $this->setCacheDir($root_path . '/cache/');
        $this->caching = Smarty::CACHING_LIFETIME_CURRENT;
        $this->assign('app_name', 'File Hosting');
   }
}
?>

config.php :

<?php
    $root_path = 'D:/xampp/htdocs/example';
    $db_user = 'xxx';
    $db_password = 'xxx';
    $db_name = 'xxx';
    $db_host = 'xxx';
    $facebook_appID = 'xxx';
    $facebook_secret = 'xxx';
?>

Errors :

Thanks for helping me.

Inside your class, you are accessing $root_path, which is at the global scope. Pass it into the constructor:

class FileHosting extends Smarty {

   // Pass $root_path as a param to the constructor
   function __construct($root_path)
   {
        parent::__construct();

        $this->setTemplateDir($root_path . '/templates/');
        $this->setCompileDir($root_path . '/templates_c/');
        $this->setConfigDir($root_path . '/configs/');
        $this->setCacheDir($root_path . '/cache/');
        $this->caching = Smarty::CACHING_LIFETIME_CURRENT;
        $this->assign('app_name', 'File Hosting');
   }
}

// Instantiate as
$smarty = new FileHosting($root_path);

The first of these errors is puzzling, as it would indicate that config.php was not properly included.

Notice: Undefined variable: root_path in D:\xampp\htdocs\example\includes\smarty_setup.php on line 3

If those are indeed the only contents of config.php (and you have not set those variables inside a function for example), you ought not get that first root_path notice.

Update

If you are failing to include config.php with a relative path, make sure:

1. config.php is in the same directory as the file you are attempting to include it from
2. Check your PHP include_path to be sure it includes the current directory .:

.

echo get_include_path();
