=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:

change in current course. (default: 600 s).

Returns: an array; first element is:
