{{Moodle 2.0}}

These are things that OU developers have found so far to check/do in code we're migrating from Moodle 1.9 to 2.0. All information on the detail of this checklist can be found elsewhere in Moodle Docs, and particularly from the [[Development:Migrating_contrib_code_to_2.0]]

Not all these things are essential for a rush job, but if you did all of them, then that'd be great. We should really mark each one with a priority of some sort!

Please add/edit this list!

==Database==

* Leave empty db/update.php file
* New $DB global objects with functions replace old db functions
* $DB parameters swapped to ?
* Add and strip slashes no longer required
* Remove use of ENUM and ENUMVALUES in install.xml file
* Remove STATEMENTS section in install.xml file, use db/install.php or db/log.php instead.
* check use of sql_substr()
* Get_records() etc now always returning arrays, empty array in case of no records found.
* Db functions throw errors not return false on error
* DB functions offer strictness parameters e.g MUST_EXIST
* Update version.php numbers (esp required)
* In version.php add $module->requires = 2010080300; // Requires this Moodle version

==Page display==

* New $OUTPUT header and footer functions
* Navigation links need to use $PAGE->navbar
* Make sure that you instantiate the moodle form before any call to $OUTPUT->header()
* Create a renderer
* Change the way image urls are displayed (not $CFG->pixpath any more)
* CSS changes
** Change styles.php to styles.css
** Change page id to new structure e.g. course-format-studyplan to page-course-view-studyplan

==Roles and Permissions:==

* array name to $capabilities in access.php
* Remove references to admin in access.php
* Rename legacy to archetypes in access.php
* Add manager archetype in access.php
* Ensure require_login as well as require_capability checks
* isguest() is depreicated, use !isloggedin() || isguestuser() instead

==Language strings==

* Rename language folder
* Change $a to {$a} in language files
* Change popup help files to _help lang strings and shorten
* Add $string[‘pluginname’] to lang file
* Add $string[‘pluginadministration’] to lang file

==Forms==

* Param_clean parameter type removed
* type required parameter for optional_and required_param
* Replace file form elements with new filepicker
* Replace htmleditor with editor form field type
* Change setHelpButton to addHelpButton. (You need to change the arguments, but the new ones are simpler.)

==General==

* Swap config_ files to edit and settings php files
* Fix whitespace & coding style
* rs_fetch_next_record($rs) is deprecated, in favour of the simple foreach($rs as $var). Calls to rs_close() must be replaced by $rs->close();
* Check functions deprecated list: [[Development:Deprecated_functions_in_2.0]]
* Use print_error() or throw new moodle_exception not error()
* Replace all url strings e.g. in redirect() calls with moodle_url instances
* Move install/uninstall functions from lib to db/install.php, lib/uninstall.php
* Move images into pix folder (especially icon.gif), get path by calling $OUTPUT->pix_url('icon', 'local_whatever');
* Add 'supports' function in lib (modname_supports()) for modules (and blocks?).
* New Backup and Restore process - [[Development:Backup_2.0_for_developers]], [[Development:Restore_2.0_for_developers]].
* Add db/log.php file if you have log calls (see any of the core modules for examples).
