linked_select_forms returns a string containing a <script></script> block |

changing the value of the first menu will result in new values being placed |
| |
in the second menu. The values in the select menu will appear in alphabetical |
| |
order unless a defined order is provided. |

linked_select_forms takes the following ordered inputs: |

| |
first menu value is given in $menu{$choice1}->{'text'}. The values |

=item * &change_content_javascript(): |
| |
|
| |
This and the next function allow you to create small sections of an |
| |
otherwise static HTML page that you can update on the fly with |
| |
Javascript, even in Netscape 4. |
| |
|
| |
The Javascript fragment returned by this function (no E<lt>scriptE<gt> tag) |
| |
must be written to the HTML page once. It will prove the Javascript |
| |
function "change(name, content)". Calling the change function with the |
| |
name of the section |
| |
you want to update, matching the name passed to C<changable_area>, and |
| |
the new content you want to put in there, will put the content into |
| |
that area. |
| |
|
| |
B<Note>: Netscape 4 only reserves enough space for the changable area |
| |
to contain room for the original contents. You need to "make space" |
| |
for whatever changes you wish to make, and be B<sure> to check your |
| |
code in Netscape 4. This feature in Netscape 4 is B<not> powerful; |
| |
it's adequate for updating a one-line status display, but little more. |
| |
This script will set the space to 100% width, so you only need to |
| |
worry about height in Netscape 4. |
| |
|
| |
Modern browsers are much less limiting, and if you can commit to the |
| |
user not using Netscape 4, this feature may be used freely with |
| |
pretty much any HTML. |

=item * &get_course_users() |
| |
|
| |
Retrieves usernames:domains for users in the specified course |

with specific role(s), and access status. |
| |
|
| |
Incoming parameters: |
| |
1. course domain |
| |
2. course number |
| |
3. access status: users must have - either active, |
| |
previous, future, or all. |
| |
4. reference to array of permissible roles |
| |
5. reference to array of section restrictions (optional) |
| |
6. reference to results object (hash of hashes). |
| |
7. reference to optional userdata hash |
| |
8. reference to optional statushash |
| |
9. flag if privileged users (except those set to unhide in |
| |
course settings) should be excluded |
| |
Keys of top level results hash are roles. |
| |
Keys of inner hashes are username:domain, with |
| |
values set to access type. |
| |
Optional userdata hash returns an array with arguments in the |

same order as loncoursedata::get_classlist() for student data. |

|
| |
Optional statushash returns |

Entries for end, start, section and status are blank because |

of the possibility of multiple values for non-student roles. |

=item * &default_quota() |
| |
|
| |
Retrieves default quota assigned for storage of user portfolio files, |
| |
given an (optional) user's institutional status. |
| |
|
| |
Incoming parameters: |
| |
1. domain |
| |
2. (Optional) institutional status(es). This is a : separated list of |
| |
status types (e.g., faculty, staff, student etc.) |
| |
which apply to the user for whom the default is being retrieved. |
| |
If the institutional status string in undefined, the domain |
| |
default quota will be returned. |
| |
|
| |
Returns: |
| |
1. Default disk quota (in Mb) for user portfolios in the domain. |
| |
2. (Optional) institutional type which determined the value of the |
| |
default quota. |
| |
|
| |
If a value has been stored in the domain's configuration db, |
| |
it will return that, otherwise it returns 20 (for backwards |
| |
compatibility with domains which have not set up a configuration |
| |
db file; the original statically defined portfolio quota was 20 Mb). |
| |
|
| |
If the user's status includes multiple types (e.g., staff and student), |
| |
the largest default quota which applies to the user determines the |
| |
default quota returned. |
