Making the ssl Connection in Drupal

There are times when the connection to your Drupal DB will need to be via ssl, such as when using an external DB service like clearDB. How do you accomplish this with regards to the settings.php file?

Simple.

Add the following to your database array:

      'pdo' => array (

            PDO::MYSQL_ATTR_SSL_CERT => 'path-to-cert.pem',

            PDO::MYSQL_ATTR_SSL_KEY => 'path-to-key.pem',

            PDO::MYSQL_ATTR_SSL_CA => 'path-to-ca.pem',

To Be, or Not To Be: the Empty Entity Reference

To be, or not to be, that is the question. Shakespeare never quite gets around to answering it, though. In Drupal 7, a similar existential question arises regarding entity references: Is it, or is it empty? Unlike Will, we can answer this question.

With other field types, we can check to see if the field is empty by doing something like this:

if (sizeof($form_state['values']['field_x'][LANGUAGE_NONE]) > 0)
