@filesource Class I2CE_FormStorage_CSV

Variables

$mod_time

of int, the unix style mod time of the sdmx file associated to the form which is the index.

$closeCSV

whether or not to close the file pointer for a CSV between access.

$resources

. An array indexed by form names of file pointers.

$locations

Array of file offesset for an id for a given form.

$lastread_locations

Array of file last read offets for a given form.

$field_indices

The column indices for the fields . Arrays indexed by form names of pairs $field=>$index

Methods

__construct()

Construct this module class

closeCSV()

Tries to get the filepointer for the CSV file

ensureIndices()

Ensures that the column indices for the fields are set.

getCSV()

Tries to get the filepointer for the CSV file

getCSVData()

Reads a line of data from ta CSV file pointer and returns it as an array of readable and enabled datavalues from the CSV indexed by the field names, 'id' and 'parent'

getFileLocation()

Get the offset in the CSV file for the specified form object

getFileLocations()

Worker moethod to the offset in the CSV file for the specified form id and store it into the {$locations} cache. Reads through the file until the specified is found. @param resource $p

getFormData()

Gets the form data for a specified form as an array of readable and enabled datavalues from the CSV indexed by the field names, 'id' and 'parent'

getRecords()

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

listDisplayFields()

  • Defined in i2ce/modules/Forms/modules/FormStorage/modules/FormStorageCSV/lib/I2CE_FormStorage_CSV.php on line 538
  • Signature: public function listDisplayFields($form,$fields,$parent,$where_data,$ordering,$limit,$mod_time)
  • 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
  • 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.
