inherited |
Create all the block instances for all the blocks that were loaded by load_blocks.
This is used, for example, to ensure that all blocks get a chance to initialise themselves via the block_base::specialize() method, before any output is done.
It is also used to create any blocks that are "requiredbytheme" by the current theme. These blocks that are auto-created have requiredbytheme set on the block instance so they are only visible on themes that require them.

array | contents of the block table. |
|
protectedinherited |
Helper method used by get_content_for_region.

This is needed because the My Moodle pages set the page context to the user's context for access control, etc. But the blocks for the system pages are stored in the system context.
Reimplemented from block_manager.

Return false as from MDL-64506
|
inherited |
Determine whether a region contains anything.
(Either any real blocks, or the add new block UI.)
(You may wonder why the $output parameter is required. Unfortunately, because of the way that blocks work, the only reliable way to find out if a block will be visible is to get the content for output, and to get the content, you need a renderer. Fortunately, this is not a performance problem, because we cache the output that is generated, and in almost every case where we call region_has_content, we are about to output the blocks anyway, so we are not doing wasted effort.)
string | $region | a block region that exists on this page. |
core_renderer | $output | a core_renderer. normally the global $OUTPUT. |
boolean | Whether there is anything in this region. |
