Methods

__construct()

The constructor for the storage mechanism the same across all all forms which share a commone storage mechanisms

• Signature: public function __construct($name,$global_options)

Parameters:

• string $name
• array $global_options
  Default to empty array. The array of options that are
  • Default Value: array()

fieldIsColumn()

• Signature: protected function fieldIsColumn($data)

Parameters:

• $data

getFieldData()

• Signature: protected function getFieldData($data)

Parameters:

• $data

getFormObj()

Get a (cached) form object for the given form

• Signature: protected function getFormObj($form)
• Returns: I2CE_Form or false on failure.

Parameters:

• string $form

getRequiredFieldsQuery()

Construct a query (to be used as a sub-select) to view the fields of the given form. It always will return the id of the form as well If it is scalar and non-boolean, it is consider to be the ID of the parent, and then we get all forms with parent the given id. @param callback $field_refernece_callback. A callback function whose first arguement is the form, the second arguements is the field and which returns the way the field value should be references as a field. If the callback is null (the default) then the reference used is "$form+$field" time greater than or equal to $mod_time. If the form storage has no way of tracking modifucation time, all entries are listed.

• Signature: public function getRequiredFieldsQuery($form,$fields,$id,$parent,$field_reference_callback,$mod_time)
• Returns: string the query or false on failed.

Parameters:

• string $form
• mixed $fields
  Either a string, the field, or an array of string, the fields.
• mixed $id
  Defaults to null. If non-null it is the id that we wish to limit to.
  • Default Value: null
• boolean $parent
  Defaults to false. If true, we include the parent id as a referenced field
  • Default Value: false
• $field_reference_callback
  • Default Value: null
• integer $mod_time
  Defaults to -1. If non-negative, we only list the requested fields for an id if at least one of them has a modification
  • Default Value: -1

getStorageOptions()

Checks that the storage mechansim for the given form is 'multi_flat' and has storage options.

• Signature: protected function getStorageOptions($form)
• Returns: mixed I2CE_MagicDataNode of flat storage options on success, false on failure.

Parameters:

• string $form

isWritable()

Checks to see if this storage mechansim is writable

• Signature: public function isWritable()
• Returns: boolean. false
