Ignore case in check for valid PDF file extension

Deletes double declared variable ($result) in sub grade_pdf.

Avoids a server-error when uploading a pdf-file without formfields.

- Check if symb is in current list of resources via navmaps,
  instead of lesser check via &lonnet::is_on_map() for resource.
- If resource is in a folder or composite page added via DOCS,
  can check if domain and courseID match those of current course.
   - generate warnings, if not.

- Check resource is in course, before making submission.
- Display warning instead of grade display if no form items were found in course map.
- Some coding style changes: keys().

- Ensure user is in course context.
- use File::MMagic to confirm a PDF file was uploaded.
- Breadcrumb trail for two step process: 1. upload form, 2. processing result.
- Check permission from canuse_pdfforms course config.
  - if none set, default to default for domain of course.

- Making pdfupload more like the rest of LON-CAPA.
  - Authz handler: lonacc
  - path: /adm/pdfupload
  - remove "use package" for packages which are not actually used
  - use routine in loncommon.pm to generate HTTP header.

- Consistent wording.
  - "Navigate" no longer used.

- Added breadcrumbs
- Wrap Upload button in <p>aragraph (padding)

- Corrected handler info text
- First check for valid user, then start data_table
- Optimized wrong-username-message:
    - Standard error style
    - Standard format username:domain
    - Optimized &mt usage

- fix problem with students pdf-upload

I don't know what exactly went wrong. There shut be different cases with advanced roles.
More research is necessary... good night (:

- showing 'Your are correct.' in overview table when get APPROX_ANS response for a problem

- By default, first arg passed to &start_page has &mt() applied to it, within locnommon.pm.

- parse responses for problem status like EXACT_ANS, APPROX_ANS and INCORRECT into human readable format

- fix TODO "get a Problemname" including a clean part information
- localize title in page header.
- call end_page() for a clean page closure.

Optimized screen layout, wording and localization:
- Wording
- Optimized mt usage
- Added new phrases to de.pm
- Always separate Navigate link from rest of screen by <hr>
- Make headlines headlines
- Added error style to error message
- Corrected grading table header and added table headline

Optimized screen layout and code routines:
- Replaced pick_boxish code by real pick_box routines
- Corrected Navigate link

- correct localization
- correct web-design with using user addicted CSS entries for pick_boxes
- correct web-design for problem results with data_table
- don't show partnumber for problems with only one part in result table

in the end:
- stundents are able to upload PDF-Forms

XHTML conform tags (input, br, hr)

Upgrade for PDF-Forms.

Now only perl is used to read out PDF-Formdata. Before you copy lonpdfupload.pm in to your Apache-folder check the needed Steps below.

----------

Enable PDF-Forms in LON-CAPA

First you need to install the AcroTeX-education bundle from ctan.

Get the package and unzip it:

    [root@loncapa ]# wget http://tug.ctan.org/get/macros/latex/contrib/acrotex.zip
    [root@loncapa ]# unzip acrotex.zip

go into the acrotex-folder and install

    [root@loncapa ]# cd acrotex
    [root@loncapa acrotex]# latex acrotex.ins

Now move the folder acrotex file into the latex path. You can easy find it by searching for "cite.sty" or some other tex-packages.

    [root@loncapa /]# locate cite.sty
    /usr/share/texmf/tex/latex/cite/cite.sty
    /usr/share/texmf/tex/latex/cite/drftcite.sty
    /usr/share/texmf/tex/latex/cite/overcite.sty
    On CentOS the latex path is: /usr/share/texmf/tex/latex/ (perhaps there is different to

    [root@loncapa acrotex]# cd ..
    [root@loncapa ]# mv acrotex /usr/share/texmf/tex/latex/

Remove the acrotex.zip

    [root@loncapa]# rm acrotex.zip

After that you must rehash tex:

    [root@loncapa ]# texhash

Now you are able to print PDF with Forms (Radiobutton-, Comboboxes-, Textfield based problems).

The second thing to do is to enable the Upload-script lonpdfupload.pm. Before you can use it you have to install CAM::PDF for perl. It is available on CPAN so you can use the perl –MCPAN -eshell.

    [root@loncapa ~]# perl -MCPAN -eshell

    cpan shell -- CPAN exploration and modules installation (v1.7602)
    ReadLine support enabled

    cpan>install CAM::PDF
    (…follow installation and also install the dependencies)
    cpan>exit

Next you need to copy the upload-script from CVS to the LON-CAPA Apache folder.

    [root@loncapa ~]# cp [your-cvs-folder]/loncom/interface/lonpdfupload.pm /home/httpd/lib/perl/Apache/

Now restart httpd:
    [root@loncapa ~]# /etc/init.d/httpd restart
