Base class for course formats.
Each course format must declare class class format_FORMATNAME extends format_base {} in file lib.php
For each course just one instance of this class is created and it will always be returned by course_get_format($courseorid). Format may store it's specific course-dependent options in variables of this class.
In rare cases instance of child class may be created just for format without course id i.e. to check if format supports AJAX.
Also course formats may extend class section_info and overwrite format_base::build_section_cache() to return more information about sections.
If you are upgrading from Moodle 2.3 start with copying the class format_legacy and renaming it to format_FORMATNAME, then move the code from your callback functions into appropriate functions of the class.
|

Creates a new instance of class.
Please use course_get_format($courseorid) to get an instance of the format class
string | $format | |

stdClass | cm_info | $cm | course module (may be null if we are displaying a form for adding a module) |
stdClass | section_info | $section | section where this module is located or will be added to |
bool |
Reimplemented in format_weeks, format_topics, format_social, and format_site.
format_base::can_delete_section | ( | $section | ) |
Whether this format allows to delete sections.
If format supports deleting sections it is also recommended to define language string 'deletesection' inside the format.
Do not call this function directly, instead use course_can_delete_section()
int | stdClass | section_info | $section |
bool |
Reimplemented in format_weeks, and format_topics.
format_base::course_content_footer | ( | ) |
Course-specific information to be output immediately below content on any course page.
See format_base::course_header() for usage
null|renderable | null for no output or object with data for plugin renderer |
format_base::course_content_header | ( | ) |
Course-specific information to be output immediately above content on any course page.
See format_base::course_header() for usage
null|renderable | null for no output or object with data for plugin renderer |
format_base::course_footer | ( | ) |
Course-specific information to be output on any course page (usually in the beginning of standard footer)
See format_base::course_header() for usage
null|renderable | null for no output or object with data for plugin renderer |
format_base::course_format_options | ( | $foreditform = false | ) |
Definitions of the additional options that this course format uses for course.
This function may be called often, it should be as fast as possible. Avoid using get_string() method, use "new lang_string()" instead It is not recommended to use dynamic or course-dependant expressions here This function may be also called when course does not exist yet.
Option names must be different from fields in the {course} talbe or any form elements on course edit form, it may even make sence to use special prefix for them.
Each option must have the option name as a key and the array of properties as a value: 'default' - default value for this option (assumed null if not specified) 'type' - type of the option value (PARAM_INT, PARAM_RAW, etc.)
Additional properties used by default implementation of format_base::create_edit_form_elements() (calls this method with $foreditform = true) 'label' - localised human-readable label for the edit form 'element_type' - type of the form element, default 'text' 'element_attributes' - additional attributes for the form element, these are 4th and further arguments in the moodleform::addElement() method 'help' - string for help button. Note that if 'help' value is 'myoption' then the string with the name 'myoption_help' must exist in the language file 'help_component' - language component to look for help string, by default this the component for this course format
This is an interface for creating simple form elements. If format plugin wants to use other methods such as disableIf, it can be done by overriding create_edit_form_elements().
Course format options can be accessed as: $this->get_course()->OPTIONNAME (inside the format class) course_get_format($course)->get_course()->OPTIONNAME (outside of format class)
All course options are returned by calling: $this->get_format_options();

format_base::editsection_form | ( | $action, | |
$customdata = array() |
|||
) |
Return an instance of moodleform to edit a specified section.
Default implementation returns instance of editsection_form that automatically adds additional fields defined in format_base::section_format_options()
Format plugins may extend editsection_form if they want to have custom edit section form.

format_base::extend_course_navigation | ( | $navigation, | |
navigation_node | $node | ||
) |
Loads all of the course sections into the navigation.
This method is called from global_navigation::load_course_sections()
By default the method global_navigation::load_generic_course_sections() is called
When overwriting please note that navigationlib relies on using the correct values for arguments $type and $key in navigation_node::add()
Example of code creating a section node: $sectionnode = $node->add($sectionname, $url, navigation_node::TYPE_SECTION, null, $section->id); $sectionnode->nodetype = navigation_node::NODETYPE_BRANCH;
Example of code creating an activity node: $activitynode = $sectionnode->add($activityname, $action, navigation_node::TYPE_ACTIVITY, null, $activity->id, $icon); if (global_navigation::module_extends_navigation($activity->modname)) { $activitynode->nodetype = navigation_node::NODETYPE_BRANCH; } else { $activitynode->nodetype = navigation_node::NODETYPE_LEAF; }
Also note that if $navigation->includesectionnum is not null, the section with this relative number needs is expected to be loaded

format_base::get_last_section_number | ( | ) |
Method used in the rendered and during backup instead of legacy 'numsections'.
Default renderer will treat sections with sectionnumber greater that the value returned by this method as "orphaned" and not display them on the course page unless in editing mode. Backup will store this value as 'numsections'.
This method ensures that 3rd party course format plugins that still use 'numsections' continue to work but at the same time we no longer expect formats to have 'numsections' property.

format_base::get_view_url | ( | $section, | |
$options = array() |
|||
) |
The URL to use for the specified course (with section)
Please note that course view page /course/view.php?id=COURSEID is hardcoded in many places in core and contributed modules. If course format wants to change the location of the view script, it is not enough to change just this function. Do not forget to add proper redirection.
int | stdClass | $section | Section object from database or just field course_sections.section if null the course view page is returned |
array | $options | options for view URL. At the moment core uses: 'navigation' (bool) if true and section has no separate page, the function returns null 'sr' (int) used by multipage formats to specify to which section to return |

Reimplemented in format_weeks, format_topics, format_social, format_singleactivity, format_site, and format_legacy.
format_base::has_view_page | ( | ) |
Returns true if the course has a front page.
This function is called to determine if the course has a view page, whether or not it contains a listing of activities. It can be useful to set this to false when the course format has only one activity and ignores the course page. Or if there are multiple activities but no page to see the centralised information.
Initially this was created to know if forms should add a button to return to the course page. So if 'Return to course' does not make sense in your format your should probably return false.

Definitions of the additional options that this course format uses for section.
See format_base::course_format_options() for return array definition.
Additionally section format options may have property 'cache' set to true if this option needs to be cached in }. The 'cache' property * is recommended to be set only for fields used in format_base::get_section_name(), } and format_base::get_view_url()
For better performance cached options are recommended to have 'cachedefault' property Unlike 'default', 'cachedefault' should be static and not access get_config().
Regardless of value of 'cache' all options are accessed in the code as $sectioninfo->OPTIONNAME where $sectioninfo is instance of section_info, returned by get_fast_modinfo($course)->get_section_info($sectionnum) or get_fast_modinfo($course)->get_section_info_all()
All format options for particular section are returned by calling: $this->get_format_options($section);

Note: affected user can be retrieved as: $section->modinfo->userid
Course format plugins can override the method to change the properties $available and $availableinfo that were calculated by conditional availability. To make section unavailable set: $available = false; To make unavailable section completely hidden set: $availableinfo = ''; To make unavailable section visible with availability message set: $availableinfo = get_string('sectionhidden', 'format_xxx');
section_info | $section | |
bool | $available | the 'available' propery of the section_info as it was evaluated by conditional availability. Can be changed by the method but 'false' can not be overridden by 'true'. |
