=head1 Routines for building display used to search for courses


=over 4

=item * &build_filters()

Create markup for a table used to set filters to use when selecting
courses in a domain. Used by lonpickcourse.pm, lonmodifycourse.pm
and quotacheck.pl


Inputs:

filterlist - anonymous array of fields to include as potential filters

crstype - course type

roleelement - fifth arg in selectcourse_link() populates fifth arg in javascript: opencrsbrowser() function, used
to pop-open a course selector (will contain "extra element").

multelement - if multiple course selections will be allowed, this will be a hidden form element: name: multiple; value: 1

filter - anonymous hash of criteria and their values

action - form action

numfiltersref - ref to scalar (count of number of elements in institutional codes -- e.g., 4 for year, semester, department, and number)

caller - caller context (e.g., set to 'modifycourse' when routine is called from lonmodifycourse.pm)

cloneruname - username of owner of new course who wants to clone

clonerudom - domain of owner of new course who wants to clone

typeelem - text to use for left column in row containing course type (i.e., Course, Community or Course/Community)

codetitlesref - reference to array of titles of components in institutional codes (official courses)

codedom - domain

formname - value of form element named "form".

fixeddom - domain, if fixed.

prevphase - value to assign to form element named "phase" when going back to the previous screen

cnameelement - name of form element in form on opener page which will receive title of selected course

cnumelement - name of form element in form on opener page which will receive courseID of selected course

cdomelement - name of form element in form on opener page which will receive domain of selected course

setroles - includes access constraint identifier when setting a roles-based condition for acces to a portfolio file

clonetext - hidden form elements containing list of courses cloneable by intended course owner when DC creates a course

clonewarning - warning message about missing information for intended course owner when DC creates a course


Returns: $output - HTML for display of search criteria, and hidden form elements.


Side Effects: None

=item * &timebased_select_form()

Create markup for a dropdown list used to select a time-based
filter e.g., Course Activity, Course Created, when searching for courses
or communities

Inputs:

item - name of form element (sincefilter or createdfilter)

filter - anonymous hash of criteria and their values

Returns: HTML for a select box contained a blank, then six time selections,
with value set in incoming form variables currently selected.

Side Effects: None

=item * &js_changer()

Create script tag containing Javascript used to submit course search form
when course type or domain is changed, and also to hide 'Searching ...' on
page load completion for page showing search result.

Inputs: None

Returns: markup containing updateFilters() and hideSearching() javascript functions.

Side Effects: None

=pod

=item * &search_courses()

Process selected filters form course search form and pass to lonnet::courseiddump
to retrieve a hash for which keys are courseIDs which match the selected filters.

Inputs:

dom - domain being searched

type - course type ('Course' or 'Community' or '.' if any).

filter - anonymous hash of criteria and their values

numtitles - for institutional codes - number of categories

cloneruname - optional username of new course owner

clonerudom - optional domain of new course owner

domcloner - Optional "domcloner" flag; has value=1 if user has ccc priv in domain being filtered by,
(used when DC is using course creation form)

codetitles - reference to array of titles of components in institutional codes (official courses).


Returns: %courses - hash of courses satisfying search criteria, keys = course IDs, values are corresponding colon-separated escaped description, institutional code, owner and type.


Side Effects: None
