=item * &excess_filesize_warning()

Returns warning message if upload of file to authoring space, or copying
of existing file within authoring space will cause quota for the authoring
space to be exceeded.

Same, if upload of a file directly to a course/community via Course Editor
will cause quota for uploaded content for the course to be exceeded.

Inputs: 7
1. username or coursenum
2. domain
3. context ('author' or 'course')
4. filename of file for which action is being requested
5. filesize (kB) of file
6. action being taken: copy or upload.
7. quotatype (in course context -- official, unofficial, community or textbook).

Returns: 1 scalar: HTML to display containing warning if quota would be exceeded,
otherwise return null.

=item * clean_path($name)

Performs clean-up of directories, subdirectories and filename in an
embedded object, referenced in an HTML file which is being uploaded
to a course or portfolio, where
"Upload embedded images/multimedia files if HTML file" checkbox was
checked.

Clean-up is similar to replacements in lonnet::clean_filename()
except each / between sub-directory and next level is preserved.

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

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

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).

cc_clone - escaped comma separated list of courses for which course cloner has active CC role
(and so can clone automatically)

reqcrsdom - domain of new course, where search_courses is used to identify potential courses to clone

reqinstcode - institutional code of new course, where search_courses is used to identify potential
courses to clone

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