Migrating to 2.0 checklist
From MoodleDocs
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 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: 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 - Backup_2.0_for_developers, Restore_2.0_for_developers.
- Add db/log.php file if you have log calls (see any of the core modules for examples).
