As a regression of MDL-55360, it was not possible to create new workshops if the field "Submission grade to pass" or "Assessment grade to pass" was left empty. The validation failed with "You must enter a number here". The fields submissiongradepass and gradinggradepass are always present as we explicitly define them in the mod form. So the isset() condition in the validation was useless and it did not allow to submit the form with these fields empty. Additionally, the unformat_float() returns null only if it receives empty value on the input. Which can't happen in our case so I am removing this condition to improve the readability of the code.
ACTIVITY MODULES
----------------
These are main modules in Moodle, allowing various activities.
Each of these modules contains a number of expected components:
mod_form.php: a form to setup/update a module instance
version.php: defines some meta-info and provides upgrading code
pix/icon.gif: a 16x16 icon for the module
db/install.xml: an SQL dump of all the required db tables and data
index.php: a page to list all instances in a course
view.php: a page to view a particular instance
lib.php: any/all functions defined by the module should be in here.
constants should be defined using MODULENAME_xxxxxx
functions should be defined using modulename_xxxxxx
There are a number of standard functions:
modulename_add_instance()
modulename_update_instance()
modulename_delete_instance()
modulename_user_complete()
modulename_user_outline()
modulename_cron()
modulename_print_recent_activity()
