MDL-26425 tablelib better validation of the sort code, also some cleanup.
You may think that the extra validation is unnecessary, since the sort fields are already validated when the URL parameters are parsed, however that overlooks an important point. There may be other options that affect which columns are in the SQL, for example the quiz show individual question grades setting. These other options can cause a column that was in the table, and being sorted on, to disappear. Therefore, it is necessary to re-validate the sort columns when they are used, to make sure they are still present, otherwise you can get ORDER BY sql that refers to non-existant columns, which then causes DB errors.
QUICK INSTALL ============= For the impatient, here is a basic outline of the installation process, which normally takes me only a few minutes: 1) Move the Moodle files into your web directory. 2) Create a single database for Moodle to store all it's tables in (or choose an existing database). 3) Visit your Moodle site with a browser, you should be taken to the install.php script, which will lead you through creating a config.php file and then setting up Moodle, creating an admin account etc. 4) Set up a cron task to call the file admin/cron.php every five minutes or so. For more information, see the INSTALL DOCUMENTATION: http://docs.moodle.org/en/Installing_Moodle Good luck and have fun! Martin Dougiamas, Lead Developer
