This article describes the abstract class I2CE_FormStorage_Mechanism .

@filesource Class I2CE_Module_FormStorage_Mechanism

Constants

I2CE_FormStorage_Mechanism::CHANGE_INITIAL

Constant signifying an initial entry. Defined as: 1

I2CE_FormStorage_Mechanism::CHANGE_VERIFY

Constant signifying a verified entry. Defined as: 2

I2CE_FormStorage_Mechanism::CHANGE_CORRECTION

Constant signifying a corrected entry. Defined as: 3

I2CE_FormStorage_Mechanism::CHANGE_UPDATE

Variables

$name

The short name for this storage mechanism

$global_options

$storage_options_cache

of I2CE_MagicDataNodes. The keys are the names of forms which have flat storage.

$ordering

Methods

FF_IG_setSequence()

Set FormField_INT_GENERATE sequence

FF_populateHistory()

Populate the history of entries for the form field if the storage module handles history.

FF_save()

Save the FormField to the database.

__construct()

The constructor for the storage mechanism

changeID()

Change the id of the given form

compareFormsByFields()

Compares two forms to see which is greater based on the field ordering set in $this->ordering @param $form1 @param $form2

delete()

Deletes a form from the entry tables.

getFormsById()

Gets the required fields. @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"

  • Defined in i2ce/modules/Forms/modules/FormStorage/lib/I2CE_FormStorage_Mechanism.php on line 346
  • Signature: public function getFormsById($form,$parent,$where_data,$ordering,$limit)
  • Parameters:
    • string $form
      The form we are select from
    • boolean $parent
      Defaults to false. If true, we include the parent id as a referenced field. 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.
    • mixed $where_data
      array or class implementing ArrayAccess, Iterator, and Countable (e.g. MagicDataNode) . the where data.
      • Default Value: array()
    • array $ordering
      An array of fields to order by. Defaults to the empty array. Prepend a - to order by in descending order.
      • Default Value: array()
    • mixed $limit
      Defaults to false. It true, returns only one result. If an integer it is the numeber of records to limit to. If it is as an array of two integers, it is the offset and then number of results to limit to.
      • Default Value: false
  • Returns: array
    with keys id's and values the I2CE_Form instance.

getIdsAsChild()

Gets the id's for the given child for this form.

getLimitedFields()

getRecords()

Return an array of all the record ids for a given form.

getStorageOptions()

Gets the storage options for the given form.

globalFieldUpdateByFunction()

update value of each instanceo of a given form field by a pho function call

hasRecord()

Checks if the given record exists.

isWritable()

Checks to see if this storage mechansim implements the writing methods. You need to override this in a subclass that implements writable

listDisplayFields()

  • Defined in i2ce/modules/Forms/modules/FormStorage/lib/I2CE_FormStorage_Mechanism.php on line 549
  • Signature: public function listDisplayFields($form,$fields,$parent,$where_data,$ordering,$limit,$mod_time,$user)
  • Parameters:
    • string $form
      THe form name
    • array $fields
      of string. The fields we want returned Can include the special field 'last_modified' to get the last modification time for any of the fields of that form which is returned in the format "Y-m-d H:i:s"
    • boolean $parent
      Defaults to false. 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. If true, we return the parent as one of the fields.
      • Default Value: false
    • array $where_data
      contains the where clause information about this form or a nested
      • Default Value: array()
    • array $ordering
      An array of fields to order by. Defaults to the empty array. Prepend a - to order by in descending order.
      • Default Value: array()
    • mixed $limit
      Defaults to false. It true, returns only one result. If an integer it is the numeber of records to limit to. If it is as an array of two integers, it is the offset and then number of results to limit to.
      • Default Value: false
    • 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 time greater than or equal to $mod_time. If the form storage has no way of tracking modifucation time, all entries are listed.
      • Default Value: -1
    • mixed $user
      The user id of the user to limit the results to so it only returns results limited to that user. This can be a single value or an array
      • Default Value: false
  • Returns: mixed
    an array with key id's and value and array of values. the array of values has as keys the fields with their corresponding value.

  • Returns: mixed
    an array with key id's and value and array of values. the array of values has as keys the fields with their corresponding value.

lookupDisplayField()

Looks up the description of the item based on the code. This is the default method that most implementations of lookup () use. It finds the description of the object based on the code and saves it in the cache and returns it.

lookupField()

Looks up the description of the item based on the code. This is the default method that most implementations of lookup () use. It finds the description of the object based on the code and saves it in the cache and returns it.

populate()

Populate the member variables of the object from the database.

populateHistory()

Populate the member variables of the object from the database.

release()

Release any resourced held by this form storage mechanism for the indicated form

save()

Save a form object into entry tables. If this functio is over-written, it should include the fuzzy method call foreach ($form as $field) { $field->save(true/false, $user) }

search()

  • Defined in i2ce/modules/Forms/modules/FormStorage/lib/I2CE_FormStorage_Mechanism.php on line 628
  • Signature: public function search($form,$parent,$where_data,$ordering,$limit)
  • Parameters:
    • string $form
      The form name.
    • boolean $parent
      Defaults to false. 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.
      • Default Value: false
    • mixed $where_data
      array or class implementing ArrayAccess, Iterator, and Countable (e.g. MagicDataNode) . the where data.
      • Default Value: array()
    • array $ordering
      An array of fields to order by. Defaults to the empty array. Prepend a - to order by in descending order.
      • Default Value: array()
    • mixed $limit
      Defaults to false. It true, returns only one result. If an integer it is the numeber of records to limit to. If it is as an array of two integers, it is the offset and then number of results to limit to.
      • Default Value: false
  • Returns: mixed
    an array of matching form ids. However, ff $limit_one is true or 1 or array ($offset,1) then then we return either the id or false, if none found or there was an error.

setStorageOptions()

Public set the more storage options for a given form
