=item &parmval() |
|
|
|
Determine the value of a parameter. |
|
|
|
Inputs: $what, the parameter needed, $symb, $uname, $udom, $csec |
|
|
|
Returns: The value of a parameter, or '' if none. |
|
|
|
This function cascades through the possible levels searching for a value for |
|
a parameter. The levels are checked in the following order: |
|
user, course (at section level and course level), map, and lonnet::metadata. |
|
This function uses %parmhash, which must be tied prior to calling it. |
|
This function also requires %courseopt and %useropt to be initialized for |
|
this user and course. |

Determine the value of a parameter. |

Inputs: $what, the parameter needed, $sheet, the safe space |
|
|
|
Returns: The value of a parameter, or '' if none. |
|
|
|
This function cascades through the possible levels searching for a value for |
|
a parameter. The levels are checked in the following order: |
|
user, course (at section level and course level), map, and lonnet::metadata. |
|
This function uses %parmhash, which must be tied prior to calling it. |
|
This function also requires %courseopt and %useropt to be initialized for |
|
this user and course. |
