Set up a particular instance of this class given data from the block_insances table and the current page.
(See block_manager::load_blocks().)
| stdClass | $instance | data from block_insances, block_positions, etc. |
| moodle_page | $page | the page this block is on. |
|
inherited |
Tests if this block has been implemented correctly.
Also, $errors isn't used right now
| boolean |

The information returned here is processed by the blocks_name_allowed_in_format() function. Look there if you need to know exactly how this works.
Default case: everything except mod and tag.

(Called once per block, not per instance!)

This method can be overriden to add some extra checks to decide whether the block can be added or not to a page.
It doesn't need to do the standard capability checks as they will be performed by has_add_block_capability(). This method is user agnostic. If you want to check if a user can add a block or not, you should use user_can_addto().
| moodle_page | $page | The page where this block will be added. |
| bool | Whether the block can be added or not to the given page. |
Reimplemented in block_accessreview, block_badges, block_blog_menu, block_blog_recent, block_blog_tags, block_comments, block_completionstatus, block_globalsearch, block_glossary_random, block_lp, block_mnet_hosts, and block_tags.

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.
| $output | The core_renderer to use when generating the output. |
| string | the HTML that should appearn in the body of the block. |
Reimplemented in block_list, and block_tree.
|
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:
| string |
Reimplemented in block_activity_modules, block_admin_bookmarks, block_blog_menu, block_course_list, block_navigation, block_search_forums, and block_settings.
| block_online_users::get_config_for_external | ( | ) |
Return the plugin config settings for external functions.
| stdClass | the configs for both the block instance and plugin |
Reimplemented from block_base.
| block_online_users::get_content | ( | ) |
Parent class version of this function simply returns NULL This should be implemented by the derived class to return the content object.
| stdObject |
Reimplemented from block_base.
|
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 core_external\util\format_text, core_external\utilformat_string functions for formatting or external_util\get_area_files for files.
| core_renderer | $output | the rendered used for output |
| stdClass | object containing the block title, central content, footer and linked files (if any). |
Reimplemented in block_html.
|
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 html_attributes(), formatted_contents() or get_content(), hide_header(), (get_edit_controls), etc.
| block_contents | a representation of the block, for rendering. |
|
inherited |
Returns the class $content_type var value.
Intentionally doesn't check if content_type is set. This is already done in _self_test()
| string\$this-,>content_type |
|
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_navigation, and block_settings.
|
inherited |
Returns the class $title var value.
Intentionally doesn't check if a title is set. This is already done in _self_test()
| string\$this-,>title |
| block_online_users::has_config | ( | ) |
Subclasses should override this and return true if the subclass block has a settings.php file.
| boolean |
Reimplemented from block_base.
|
inherited |
Default return is false - header will be shown.
| boolean |
Reimplemented in block_course_summary, and block_myoverview.
|
inherited |
Return any HTML attributes that you want added to the outer.

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

Allows the block class to have a say in the user's ability to create new instances of this block.
The framework has first say in whether this will be allowed (e.g., no adding allowed unless in edit mode) but if the framework does allow it, the block can still decide to refuse. This function has access to the complete page object, the creation related to which is being determined.
