Member Function Documentation

◆ _load_instance()

block_base::_load_instance	(	$instance,
		$page
	)

inherited

Set up a particular instance of this class given data from the block_insances table and the current page.

(See block_manager::load_blocks().)

Parameters

stdClass	$instance	data from block_insances, block_positions, etc.
moodle_page	$the	page this block is on.

◆ _self_test()

block_base::_self_test ( )

inherited

Tests if this block has been implemented correctly.

Also, $errors isn't used right now

Return values

boolean

◆ applicable_formats()

block_myoverview::applicable_formats ( )

Locations where block can be displayed.

Return values

array

Reimplemented from block_base.

◆ before_delete()

block_base::before_delete ( )

inherited

Function that can be overridden to do extra cleanup before the database tables are deleted.

(Called once per block, not per instance!)

Reimplemented in block_myprofile.

◆ config_save()

block_base::config_save ( $data )

inherited

Default behavior: save all variables as $CFG properties You don't need to override this if you 're satisfied with the above.

Deprecated:: since Moodle 2.9 MDL-49385 - Please use Admin Settings functionality to save block configuration.

◆ formatted_contents()

block_base::formatted_contents ( $output )

protectedinherited

Convert the contents of the block to HTML.

This is used by block base classes like block_list to convert the structured $this->content->list and $this->content->icons arrays to HTML. So, in most blocks, you probaby want to override the get_contents() method, which generates that structured representation of the contents.

Parameters

$output The core_renderer to use when generating the output.

Return values

string the HTML that should appearn in the body of the block.

Since: Moodle 2.0.

Reimplemented in block_tree, and block_list.

◆ get_aria_role()

block_base::get_aria_role ( )

inherited

Returns the aria role attribute that best describes this block.

Region is the default, but this should be overridden by a block is there is a region child, or even better a landmark child.

Options are as follows:

landmark
- application
- banner
- complementary
- contentinfo
- form
- main
- navigation
- search

Return values

string

Reimplemented in block_settings, block_search_forums, block_navigation, block_course_list, block_blog_menu, block_admin_bookmarks, and block_activity_modules.

◆ get_config_for_external()

block_myoverview::get_config_for_external ( )

Return the plugin config settings for external functions.

Return values

stdClass the configs for both the block instance and plugin

Since: Moodle 3.8

Reimplemented from block_base.

◆ get_content()

block_myoverview::get_content ( )

Returns the contents.

Return values

stdClass contents of block

Reimplemented from block_base.

◆ get_content_for_external()

block_base::get_content_for_external ( $output )

inherited

Return an object containing all the block content to be returned by external functions.

If your block is returning formatted content or provide files for download, you should override this method to use the external_format_text, external_format_string functions for formatting or external_util::get_area_files for files.

Parameters

core_renderer $output the rendered used for output

Return values

stdClass object containing the block title, central content, footer and linked files (if any).

Since: Moodle 3.6

Reimplemented in block_html.

◆ get_content_for_output()

block_base::get_content_for_output ( $output )

inherited

Return a block_contents object representing the full contents of this block.

This internally calls ->get_content(), and then adds the editing controls etc.

You probably should not override this method, but instead override }, formatted_contents()} or get_content()}, * hide_header()}, (get_edit_controls), etc.

Return values

block_contents a representation of the block, for rendering.

Since: Moodle 2.0.

◆ get_content_type()

block_base::get_content_type ( )

inherited

Returns the class $content_type var value.

Intentionally doesn't check if content_type is set. This is already done in _self_test()

Return values

string::$this-,>content_type

◆ get_required_javascript()

block_base::get_required_javascript ( )

inherited

Allows the block to load any JS it requires into the page.

By default this function simply permits the user to dock the block if it is dockable.

Left null as of MDL-64506.

Reimplemented in block_settings, and block_navigation.

◆ get_title()

block_base::get_title ( )

inherited

Returns the class $title var value.

Intentionally doesn't check if a title is set. This is already done in _self_test()

Return values

string::$this-,>title

◆ has_config()

block_myoverview::has_config ( )

Allow the block to have a configuration page.

Return values

boolean

Reimplemented from block_base.

◆ hide_header()

block_base::hide_header ( )

inherited

Default return is false - header will be shown.

Return values

boolean

Reimplemented in block_course_summary.

◆ html_attributes()

block_base::html_attributes ( )

inherited

Return any HTML attributes that you want added to the outer.

that of the block when it is output.

Because of the way certain JS events are wired it is a good idea to ensure that the default values here still get set. I found the easiest way to do this and still set anything you want is to override it within your block in the following way

 function html_attributes() { $attributes = parent::html_attributes(); $attributes['class'] .= ' mynewclass'; return $attributes; }

Return values

array attribute name => value.

Reimplemented in block_navigation, block_list, and block_html.

◆ instance_allow_config()

block_base::instance_allow_config ( )

inherited

Is each block of this type going to have instance-specific configuration? Normally, this setting is controlled by instance_allow_multiple(): if multiple instances are allowed, then each will surely need its own configuration.

However, in some cases it may be necessary to provide instance configuration to blocks that do not want to allow multiple instances. In that case, make this function return true. I stress again that this makes a difference ONLY if instance_allow_multiple() returns false.

Return values

boolean

Reimplemented in block_tags, block_settings, block_section_links, block_rss_client, block_navigation, block_myprofile, block_blog_tags, block_blog_recent, block_blog_menu, and block_badges.

◆ instance_allow_multiple()

block_base::instance_allow_multiple ( )

inherited

Are you going to allow multiple instances of each block? If yes, then it is assumed that the block WILL USE per-instance configuration.
