Variables

Methods

FF_populateHistory()

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

__construct()

Construct this module class

getFields()

Generates a SQL to select the required fields. @param mixed $expr array or class implementing ArrayAccess, Iterator, and Countable (e.g. MagicDataNode) . the where data. @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_DB.php on line 323
  • Signature: public function getFields($form,$fields,$parent,$where_data,$ordering,$limit,$field_reference_callback,$mod_time,$user)
  • Parameters:
    • string $form
      The form we are select from
    • array $fields
      of string. the fields that we want to select. the keys are the fields names, the values are what we wish to select them as. 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"
      • Default Value: array()
    • 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.
    • $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
    • $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 time greater than $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: string
    the SQL Query needed to get the form/field data or false on failure.

getIdsAsChild()

    • $order_by
    • $where
    • $limit
  • Returns: array

getRecords()

Return an array of all the record ids for a given 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 @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"

      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. 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.

    • 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
