Using dbforge?

Not sure when this changed but...

to do this now (CI Version: 2.1.2), the code should be as follows:

Code:

$this->dbforge->add_field(array(
      'id' => array(
          'type' => 'INT',
          'constraint' => 11,
          'auto_increment' => TRUE
        ),
      'date TIMESTAMP DEFAULT CURRENT_TIMESTAMP',
      'name' => array(
        'type' => 'VARCHAR',
        'constraint' => 255,
        'default' => 'John Smith'
      )
));

... with extra fields (id, name) to give context.

So you can pass the whole definition for a field as a string instead of passing an array.
Also - if you just pass the string 'id' it'll auto convert to :

Code:

'id' => array(
  'type' => 'INT',
  'constraint' => 9,
  'auto_increment' => TRUE
)
