◆ extract_record()

static core\persistent::extract_record	(		$row,
			$prefix = null )

staticinherited

Extract a record from a row of data.

Most likely used in combination with self::get_sql_fields(). This method is simple enough to be used by non-persistent classes, keep that in mind when modifying it.

e.g. persistent\extract_record($row, 'user'); should work.

Parameters

stdClass	$row	The row of data.
string	$prefix	The prefix the data fields are prefixed with, defaults to the table name followed by underscore.

Return values

stdClass The extracted data.

◆ from_record()

core\persistent::from_record ( stdClass $record )

finalinherited

Parameters

stdClass $record A DB record.

Return values

static

◆ get()

core\persistent::get ( $property )

finalinherited

Data getter.

This is the main getter for all the properties. Developers can implement their own getters (get_propertyname) and they will be called by this function. Custom getters can use raw_get to get the raw value. Internally this is not used by self::to_record() or self::from_record() because the data is not expected to be validated or changed when reading/writing raw records from the DB.

Parameters

string $property The property name.

Return values

mixed

◆ get_errors()

core\persistent::get_errors ( )

finalinherited

Returns the validation errors.

protected

Get the list of expired role IDs.

Return values

int[]

◆ get_formatted_properties()

static core\persistent::get_formatted_properties ( )

static core\persistent::get_property_default_value ( $property )

staticfinalprotectedinherited

Gets the default value for a property.

This assumes that the property exists.

Parameters

string $property The property name.

Return values

mixed

◆ get_property_error_message()

static core\persistent::get_property_error_message ( $property )

staticfinalinherited

For a given record, return an array containing only those properties that are defined by the persistent.

Parameters

stdClass $record

Return values

array

◆ raw_get()

core\persistent::raw_get ( $property )

finalprotectedinherited

Internal Data getter.

This is the main getter for all the properties. Developers can implement their own getters but they should be calling self::get() in order to retrieve the value. Essentially the getters defined by the developers would only ever be used as helper methods and will not be called internally at this stage. In other words, do not expect self::to_record() or self::from_record() to use them.

This is protected because it is only for raw low level access to the data fields. Note this function is named raw_get and not get_raw to avoid naming clashes with a property named raw.

Parameters

string $property The property name.

Return values

mixed

◆ raw_set()

core\persistent::raw_set	(		$property,
			$value )

finalprotectedinherited

Data setter.

This is the main setter for all the properties. Developers can implement their own setters but they should always be calling self::set() in order to set the value. Essentially the setters defined by the developers are helper methods and will not be called internally at this stage. In other words do not expect self::to_record() or self::from_record() to use them.

This is protected because it is only for raw low level access to the data fields.

Parameters

string	$property	The property name.
mixed	$value	The value.

Return values

$this

◆ read()

core\persistent::read ( )

finalinherited

Load the data from the DB.

Return values

static

◆ record_exists()

static core\persistent::record_exists ( $id )

staticinherited

Check if a record exists by ID.

Parameters

int $id Record ID.

Return values

bool

◆ record_exists_select()

static core\persistent::record_exists_select	(		$select,
		array	$params = null )

staticinherited

Check if a records exists.

Parameters

string	$select
array	$params

Return values

bool

◆ save()

core\persistent::save ( )

finalinherited

Saves the record to the database.

If this record has an ID, then self::update() is called, otherwise self::create() is called. Before and after hooks for create() or update() will be called appropriately.

Return values

void

◆ set()

core\persistent::set	(		$property,
			$value )

finalinherited

Data setter.

This is the main setter for all the properties. Developers can implement their own setters (set_propertyname) and they will be called by this function. Custom setters should call internal_set() to finally set the value. Internally this is not used self::to_record() or self::from_record() because the data is not expected to be validated or changed when reading/writing raw records from the DB.

Parameters

string $property The property name.

Return values

$this

Exceptions

coding_exception

◆ set_expiredroles()

tool_dataprivacy\expired_context::set_expiredroles ( array $roleids )

protected

Set the list of expired role IDs.

Parameters

int[] $roleids

Return values

expired_context

◆ set_many()

core\persistent::set_many ( array $values )

finalinherited

Data setter for multiple properties.

Internally calls {

See also: set} on each property

Parameters

array $values Array of property => value elements

Return values

$this

◆ set_roleids_for()

tool_dataprivacy\expired_context::set_roleids_for	(	string	$field,
		array	$roleids )

protected

Set the list of role IDs for either expiredroles, or unexpiredroles.

Parameters

string	$field
int[]	$roleids

Return values

expired_context

◆ set_unexpiredroles()

tool_dataprivacy\expired_context::set_unexpiredroles ( array $roleids )

protected

Set the list of unexpired role IDs.

Parameters

int[] $roleids

Return values

expired_context

◆ to_record()

core\persistent::to_record ( )

finalinherited

Create a DB record from this class.

Note that this does not use any custom getter because the data here is intended to represent what is stored in the database.

Return values

stdClass

◆ update()

core\persistent::update ( )

finalinherited

Update the existing record in the DB.

Return values

bool	True on success.

◆ update_from_expiry_info()

tool_dataprivacy\expired_context::update_from_expiry_info ( expiry_info $info )

Update the expired_context from an expiry_info object which relates to this context.

Parameters

expiry_info $info

Return values

$this

◆ validate()

core\persistent::validate ( )

finalinherited

Validates the data.

Developers can implement addition validation by defining a method as follows. Note that the method MUST return a lang_string() when there is an error, and true when the data is valid.

protected function validate_propertyname($value) { if ($value !== 'My expected value') { return new lang_string('invaliddata', 'error'); } return true }

It is OK to use other properties in your custom validation methods when you need to, however note they might not have been validated yet, so try not to rely on them too much.

Note that the validation methods should be protected. Validating just one field is not recommended because of the possible dependencies between one field and another,also the field ID can be used to check whether the object is being updated or created.

When validating foreign keys the persistent should only check that the associated model exists. The validation methods should not be used to check for a change in that relationship. The API method setting the attributes on the model should be responsible for that. E.g. On a course model, the method validate_categoryid will check that the category exists. However, if a course can never be moved outside of its category it would be up to the calling code to ensure that the category ID will not be altered.

Return values

array|true Returns true when the validation passed, or an array of properties with errors.

◆ verify_protected_methods()

core\persistent::verify_protected_methods ( )

finalprotectedinherited

This function is used to verify that custom getters and setters are declared as protected.

Persistent properties should always be accessed via get('property') and set('property', 'value') which will call the custom getter or setter if it exists. We do not want to allow inconsistent access to the properties.
