Member Function Documentation

delete()

data_object::delete ( )

inherited

Deletes this object from the database.

Return values

bool

success

fetch()

static completion_aggregation::fetch ( $params )

static

Finds and returns a data_object instance based on params.

Parameters

array

$params

associative arrays varname=>value

Return values

data_object

instance of data_object or false if none found.

Reimplemented from data_object.

fetch_all()

static completion_aggregation::fetch_all ( $params )

static

Finds and returns all data_object instances based on params.

Parameters

array

$params

associative arrays varname=>value

Return values

array

array of data_object insatnces or false if none found.

Reimplemented from data_object.

fetch_all_helper()

static data_object::fetch_all_helper ( $table, $classname, $params )

staticinherited

Factory method - uses the parameters to retrieve all matching instances from the DB.

@final

Parameters

string	$table	The table name to fetch from
string	$classname	The class that you want the result instantiated as
array	$params	Any params required to select the desired row

Return values

mixed

array of object instances or false if not found

fetch_helper()

static data_object::fetch_helper ( $table, $classname, $params )

staticprotectedinherited

Factory method - uses the parameters to retrieve matching instance from the DB.

@final

Parameters

string	$table	The table name to fetch from
string	$classname	The class that you want the result instantiated as
array	$params	Any params required to select the desired row

Return values

object

Instance of $classname or false.

get_record_data()

data_object::get_record_data ( )

inherited

Returns object with fields and values that are defined in database.

Return values

stdClass

insert()

data_object::insert ( )

inherited

Records this object in the Database, sets its id to the returned value, and returns that value.

If successful this function also fetches the new object data from database and stores it in object properties.

Return values

int	PK ID if successful, false otherwise

load_optional_fields()

data_object::load_optional_fields ( )

inherited

Makes sure all the optional fields are loaded.

If id present (==instance exists in db) fetches data from db. Defaults are used for new instances.

notify_changed()

data_object::notify_changed ( $deleted )

inherited

Called immediately after the object data has been inserted, updated, or deleted in the database.

Default does nothing, can be overridden to hook in special behaviour.

Parameters

bool

$deleted

Set this to true if it has been deleted.

save()

completion_aggregation::save

(

)

Save aggregation method to database.

Return values

boolean

set_properties()

static data_object::set_properties ( & $instance, $params )

staticinherited

Given an associated array or object, cycles through each key/variable and assigns the value to the corresponding variable in this object.

@final

Parameters

data_object	$instance
array	$params

setMethod()

completion_aggregation::setMethod

(

$method

)

Set the aggregation method.

Parameters

int

$method

One of COMPLETION_AGGREGATION_ALL or COMPLETION_AGGREGATION_ANY

update()

data_object::update ( )

inherited

Updates this object in the Database, based on its object variables.

ID must be set.

Return values

bool

success

update_from_db()

data_object::update_from_db ( )

inherited

Using this object's id field, fetches the matching record in the DB, and looks at each variable in turn.

If the DB has different data, the db's data is used to update the object. This is different from the update() function, which acts on the DB record based on the object.

Return values

bool	True for success, false otherwise.

Member Data Documentation

$optional_fields

array data_object::$optional_fields = array()

inherited

Array of optional fields with default values - usually long text information that is not always needed.

If you want to create an instance without optional fields use: new data_object($only_required_fields, false);

$required_fields

array completion_aggregation::$required_fields = array('id', 'course', 'criteriatype', 'method', 'value')

Array of required table fields, must start with 'id'.

Defaults to id, course, criteriatype, method, value
