Class: I2CE List (4.1.6)

From IHRIS Wiki
For other versions, see Class: I2CE_List (versions) .


This article describes the abstract class I2CE_List .

Base object for dealing with lists of data. This is an abstract object with base code for many of the I2CE_Form interface methods. It is used for many of the list database objects such as AcademicLevel and District . It assumes all lists have a code field and by default a description field but this can be overwritten by certain objects like Cadre . @abstract

Form Fields

This class is a form class and provides the following form fields

remap

The form field remap is implemented by REMAP

i2ce_hidden

The form field i2ce_hidden is implemented by YESNO

Variables

$mapped_fields_by_form

of array index by names of lists of arrays where keys are form names, values are arrays with keys field names and values field objects

$cache

An array to cache lookup entries Any lookups done to the database will be cached in this static array so additional lookups using the same id won't have to access the database. @static

  • Parameters:
    • array $fields
      an ordered array E.g array('village+county','county','district,'region+country','country'). it is an "bottom up" array of string where strings are of the form "$form" or "$form+$link_field". In the case of the former type, then $link_field is assumed to be the next form. So for example, "county" has link field "district". If a "$form(+$link_field)" is surrounded by brackets [ ] , it is not displayed.
    • array $forms

    • array $limits
      An array with keys form names and value limit data
    • array $orders
      An array with keys form names and values array of field orders for that form. If the form name has no orders, we use default ordering for that form based on its displayed firelds
      • Default Value: array()
    • boolean $show_hidden
      Show the hidden members of the list, defaults to false.
      • Default Value: false

    • array $forms
      an array of string which are componentized @parm string $component The component we possibly wish to componentize at.
    • $component
  • Returns: string.
    They query need to turn $qry into one componentized to $component.

findLowerMatches()

For the list of displayed fields for a field, find all the ids for forms that are below the given matched form id. For example if a location has the displayed fields of: array( 'county', 'district', '[region]', 'country' ) with selectable fields: array( 'county', 'district' ) if you want to match the district: district|10 this method will return all the county ids that are in district|10. This will also return 'district|10' in the list to have a complete list of valid selectable forms.

  • Defined in i2ce/modules/Forms/modules/Lists/lib/I2CE_List.php on line 614

lookup()

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.
