Question

I have written some php/mysql queries inside node.tpl.php and page.tpl.php.

The username and password that these pages use to connect to MySQL are specified within the files.

Instead of doing this, I would like to be able to use the MySQL connection settings that are defined in Drupal’s settings.php file.

I am trying, unsuccessfully include the settings.php file into node.tpl.php and page.tpl.php.

<?php include("sites/default/settings.php") ?> 

Then I am trying to access the $databases array from settings.php like this:

$databases['default']['default']['username']

The $databases array has this structure:

$databases = array (
                   'default' => 
                        array (
                          'default' => 
                               array (
                                    'database' => 'sdnndr',
                                    'username' => 'root',
                                    'password' => '',
                                    'host' => 'localhost',
                                    'port' => '',
                                    'driver' => 'mysql',
                                    'prefix' => '',
                                ),
                        ),
              );

My approach is not working. Can anyone suggest

Answer 1

Let me count the way you are doing this wrong. You do not write queries into templates. Never. Because if you change looks later you would lose your logic. Put them in modules where they belong. You do need not include settings, it’s already included. You do not write MySQL queries because they are insecure, instead you use http://api.drupal.org/api/drupal/includes–database–database.inc/group/database/7 which encourages (and in some case even enforces) security.
