Defining attributes

Defining attributes for question types.

Attributes for question types are all configurable, non default, aspects of a question. A good example of an attribute is question text.

Question attributes are defined using an array with the name of the attribute as a key. An attribute definition supports several keys.

• type - string: The data type of the attribute. Supported types are ('html', 'string', 'boolean', 'select')
• localized - boolean: Whether this attribute should be configurable per language.
• advanced - boolean: Whether this attribute should be shown in the default or advanced tab.
• label - string: The label of the attribute in English (this is localized by the admin interface).
• options - array(string-string): Contains the options for an attribute of type 'select'.
• default - mixed: Contains the default value for the attribute.

Example:

protected $attributes = array(

   'question' => array(

       'type' => 'html',

       'localized' => true,

       'label' => 'Question text:'

   ),

   'help' => array(

       'type' => 'html',

       'localized' => true,

       'label' => 'Help text:'

   ),

   'mandatory' => array(

       'type' => 'boolean',

       'label' => 'Mandatory:'

   ),

   'display' => array(

       'label' => 'Display using:',

       'type' =>  'select',

       'options' => array(

           'radio' => 'Radio buttons',

           'dropdown' => 'Dropdown list'

       ),

       'localized' => false,

       'advanced' => false,

       'default' => 'dropdown'

   )

);
