Member Function Documentation

add_entry()

static mod_data_external::add_entry (   $databaseid,   $groupid,   $data  )

static

Adds a new entry to a database.

Parameters

int	$databaseid	the data instance id
int	$groupid	(optional) group id, 0 means that the function will determine the user group
array	$data	the fields data to be created

Return values

array

of warnings and status result

Since

Moodle 3.3

Exceptions

moodle_exception

add_entry_parameters()

static mod_data_external::add_entry_parameters ( )

static

Returns description of method parameters.

Return values

external_function_parameters

Since

Moodle 3.3

add_entry_returns()

static mod_data_external::add_entry_returns ( )

static

Returns description of method result value.

Return values

external_description

Since

Moodle 3.3

approve_entry()

static mod_data_external::approve_entry (   $entryid,   $approve = true  )

static

Approves or unapproves an entry.

Parameters

int	$entryid	the record entry id id
bool	$approve	whether to approve (true) or unapprove the entry

Return values

array

of warnings and the entries

Since

Moodle 3.3

Exceptions

moodle_exception

approve_entry_parameters()

static mod_data_external::approve_entry_parameters ( )

static

Returns description of method parameters.

Return values

external_function_parameters

Since

Moodle 3.3

approve_entry_returns()

static mod_data_external::approve_entry_returns ( )

static

Returns description of method result value.

Return values

external_description

Since

Moodle 3.3

call_external_function()

static external_api::call_external_function (   $function,   $args,   $ajaxonly = false  )

staticinherited

Call an external function validating all params/returns correctly.

Note that an external function may modify the state of the current page, so this wrapper saves and restores tha PAGE and COURSE global variables before/after calling the external function.

Parameters

string	$function	A webservice function name.
array	$args	Params array (named params)
boolean	$ajaxonly	If true, an extra check will be peformed to see if ajax is required.

Return values

array

containing keys for error (bool), exception and data.

clean_returnvalue()

static external_api::clean_returnvalue ( external_description  $description,   $response  )

staticinherited

Clean response If a response attribute is unknown from the description, we just ignore the attribute.

If a response attribute is incorrect, invalid_response_exception is thrown. Note: this function is similar to validate parameters, however it is distinct because parameters validation must be distinct from cleaning return values.

Parameters

external_description	$description	description of the return values
mixed	$response	the actual response

Return values

mixed

response with added defaults for optional items, invalid_response_exception thrown if any problem found
