◆ get_component_type()

core_search\base::get_component_type ( )
inherited

Returns the component type.

It might be a plugintype or 'core' for core subsystems.

Return values
string

◆ get_config()

◆ get_context_restriction_sql()

core_search\base_mod::get_context_restriction_sql ( \context  $context = null,
  $modname,
  $modtable,
  $paramtype = SQL_PARAMS_QM 
)
protectedinherited

Helper function that gets SQL useful for restricting a search query given a passed-in context.

The SQL returned will be zero or more JOIN statements, surrounded by whitespace, which act as restrictions on the query based on the rows in a module table.

You can pass in a null or system context, which will both return an empty string and no params.

Returns an array with two nulls if there can be no results for the activity within this context (e.g. it is a block context).

If named parameters are used, these will be named gcrs0, gcrs1, etc. The table aliases used in SQL also all begin with gcrs, to avoid conflicts.

Parameters
context | null$contextContext to restrict the query
string$modnameName of module e.g. 'forum'
string$modtableAlias of table containing module id
int$paramtypeType of SQL parameters to use (default question mark)
Return values
arrayArray with SQL and parameters; both null if no need to query
Exceptions
coding_exceptionIf called with invalid params

◆ get_contexts_to_reindex()

core_search\base_mod::get_contexts_to_reindex ( )
inherited

Gets a list of all contexts to reindex when reindexing this search area.

For modules, the default is to return all contexts for modules of that type, in order of time added (most recent first).

Return values

Reimplemented from core_search\base.

◆ get_contexts_to_reindex_extra_sql()

inherited

Gets the length of time spent indexing this area (the last time it was indexed).

Return values
int|boolTime in seconds spent indexing this area last time, false if never indexed

◆ get_levels()

staticinherited

Returns context levels property.

Return values
int

◆ get_module_name()

core_search\base_mod::get_module_name ( )
protectedinherited

Parameters

◆ get_recordset_by_timestamp()

core_search\base::get_recordset_by_timestamp (   $modifiedfrom = 0)
inherited

Returns a recordset ordered by modification date ASC.

Each record can include any data self::get_document might need but it must:

  • Include an 'id' field: Unique identifier (in this area's scope) of a document to index in the search engine If the indexed content field can contain embedded files, the 'id' value should match the filearea itemid.
  • Only return data modified since $modifiedfrom, including $modifiedform to prevent some records from not being indexed (e.g. your-timemodified-fieldname >= $modifiedfrom)
  • Order the returned data by time modified in ascending order, as core_search::manager will need to store the modified time of the last indexed document.

Since Moodle 3.4, subclasses should instead implement get_document_recordset, which has an additional context parameter. This function continues to work for implementations which haven't been updated, or where the context parameter is not required.

Parameters
int$modifiedfrom
Return values
moodle_recordset

◆ get_search_fileareas()

mod_forum\search\post::get_search_fileareas ( )

Return the context info required to index files for this search area.

Return values
array

Reimplemented from core_search\base.

◆ get_settingnames()

static core_search\base::get_settingnames ( )
staticinherited

Return a list of all required setting names.

Return values
array

◆ get_visible_name()

core_search\base::get_visible_name (   $lazyload = false)
inherited

Returns the area visible name.

Parameters
bool$lazyloadUsually false, unless when in admin settings.
Return values
string

◆ is_enabled()

core_search\base::is_enabled ( )
inherited

Is the search component enabled by the system administrator?

Return values
bool

◆ restrict_cm_access_by_group()

core_search\base_mod::restrict_cm_access_by_group ( \cm_info  $cm)
inherited

Checks whether the content of this search area should be restricted by group for a specific module.

Called at query time.

The default behaviour simply checks if the effective group mode is SEPARATEGROUPS, which is probably correct for most cases.

If restricted by group, the search query will (where supported by the engine) filter out results for groups the user does not belong to, unless the user has 'access all groups' for the activity. This affects only documents which set the 'groupid' field; results with no groupid will not be restricted.

Even if you return true to this function, you may still need to do group access checks in check_access, because the search engine may not support group restrictions.

Parameters
cm_info$cm
Return values
boolTrue to restrict by group

◆ supports_get_document_recordset()

core_search\base::supports_get_document_recordset ( )
inherited

Checks if get_document_recordset is supported for this search area.

For many uses you can simply call get_document_recordset and see if it returns false, but this function is useful when you don't want to actually call the function right away.

◆ supports_group_restriction()

mod_forum\search\post::supports_group_restriction ( )

Confirms that data entries support group restrictions.

Return values
boolTrue

Reimplemented from core_search\base_mod.

◆ uses_file_indexing()

mod_forum\search\post::uses_file_indexing ( )

Returns true if this area uses file indexing.

Return values
bool

Reimplemented from core_search\base.
