|
Restores/Store indicated form parameters from the course environment. |
|
Will not overwrite existing values of the form parameters. |
|
|
|
Inputs: |
|
a scalar describing the data (e.g. 'chart', 'problem_analysis') |
|
|
|
a hash ref describing the data to be stored. For example: |
|
|
|
%Save_Parameters = ('Status' => 'scalar', |
|
'chartoutputmode' => 'scalar', |
|
'chartoutputdata' => 'scalar', |
|
'Section' => 'array', |
|
'StudentData' => 'array', |
|
'Maps' => 'array'); |
|
|
|
Returns: both routines return nothing |
