Library of internal classes and functions for module workshop All the workshop specific functions, needed to implement the module logic, should go to here. Instead of having bunch of function named workshop_something() taking the workshop instance as the first parameter, we use a class workshop that provides all methods.

Class: workshop  - X-Ref

Full-featured workshop API

This wraps the workshop database record with a set of methods that are called
from the module itself. The class should be initialized right after you get
$workshop, $cm and $course records at the begining of the script.
__construct(stdclass $dbrecord, $cm, $course, stdclass $context=null)   X-Ref
Initializes the workshop API instance using the data from DB

Makes deep copy of all passed records properties.

For unit testing only, $cm and $course may be set to null. This is so that
you can test without having any real database objects if you like. Not all
functions will work in this situation.

param: stdClass $dbrecord Workshop instance data from {workshop} table
param: stdClass|cm_info $cm Course module record
param: stdClass $course Course record from {course} table
param: stdClass $context The context of the workshop instance

installed_allocators()   X-Ref
Return list of available allocation methods

return: array Array ['string' => 'string'] of localized allocation method names

instruction_editors_options(stdclass $context)   X-Ref
Returns an array of options for the editors that are used for submitting and assessing instructions

param: stdClass $context
return: array

percent_to_value($percent, $total)   X-Ref

param: float $percent from 0 to 100
param: float $total   the 100% value
return: float

available_maxgrades_list()   X-Ref

return: array ['string' => 'string']

available_evaluators_list()   X-Ref

available_dimension_weights_list()   X-Ref
Return an array of possible values of assessment dimension weight

return: array of integers 0, 1, 2, ..., 16

available_assessment_weights_list()   X-Ref
Return an array of possible values of assessment weight

Note there is no real reason why the maximum value here is 16. It used to be 10 in
workshop 1.x and I just decided to use the same number as in the maximum weight of
a single assessment dimension.
The value looks reasonable, though. Teachers who would want to assign themselves
higher weight probably do not want peer assessment really...

return: array of integers 0, 1, 2, ..., 16

gcd($a, $b)   X-Ref
Helper function returning the greatest common divisor

param: int $a
param: int $b

param: string|array $whitelist list of valid extensions
return: array list of invalid extensions not found in the whitelist

grades are not returned. If none grade is to be returned, this method returns false.

have the 'access all groups' permission, or share at least one
accessible group with the other user.
