TYPO3 12.4 API: ReferenceIndex

ReferenceIndex implements LoggerAwareInterface uses LoggerAwareTrait

Reference index processing and relation extraction

Internal

Extensions shouldn't fiddle with the reference index themselves, it's task of DataHandler to do this.

Interfaces

LoggerAwareInterface

Properties

$eventDispatcher : EventDispatcherInterface
$excludedColumns : array<string|int, mixed>: Definition of fields to exclude from ReferenceIndex in *every* table
$excludedTables : array<string|int, mixed>: Definition of tables to exclude from the ReferenceIndex
$hashVersion : int: Number which we can increase if a change in the code means we will have to force a re-generation of the index.
$relations : array<string|int, mixed>: An index of all found references of a single record
$softReferenceParserFactory : SoftReferenceParserFactory
$tableRelationFieldCache : array<string|int, mixed>: A list of fields that may contain relations per TCA table.
$temp_flexRelations : array<string|int, mixed>: This array holds the FlexForm references of a record
$workspaceId : int: Current workspace id

Methods

__construct() : mixed
getNumberOfReferencedRecords() : int: Returns the amount of references for the given record
getRelations() : array<string|int, mixed>: Returns relation information for a $table/$row-array Traverses all fields in input row which are configured in TCA/columns It looks for hard relations to records in the TCA types "select" and "group"
getRelations_flexFormCallBack() : mixed: Callback function for traversing the FlexForm structure in relation to finding DB references!
setReferenceValue() : string|bool|array<string|int, mixed>: Setting the value of a reference or removing it completely.
setWorkspaceId() : mixed: Sets the current workspace id
updateIndex() : array<string|int, mixed>: Updating Index (External API)
updateRefIndexTable() : array<string|int, mixed>: Call this function to update the sys_refindex table for a record (even one just deleted) NOTICE: Currently, references updated for a deleted-flagged record will not include those from within FlexForm fields in some cases where the data structure is defined by another record since the resolving process ignores deleted records! This will also result in bad cleaning up in DataHandler I think... Anyway, that's the story of FlexForms; as long as the DS can change, lots of references can get lost in no time.

$excludedColumns

Definition of fields to exclude from ReferenceIndex in *every* table


    protected
        array<string|int, mixed>
    $excludedColumns
     = ['uid' => true, 'perms_userid' => true, 'perms_groupid' => true, 'perms_user' => true, 'perms_group' => true, 'perms_everybody' => true, 'pid' => true]

Implemented as array with fields as keys and booleans as values for fast isset() lookup instead of slow in_array()

$excludedTables

Definition of tables to exclude from the ReferenceIndex


    protected
        array<string|int, mixed>
    $excludedTables
     = ['sys_log' => true, 'tx_extensionmanager_domain_model_extension' => true]

Only tables which do not contain any relations and never did so far since references also won't be deleted for these. Since only tables with an entry in $GLOBALS['TCA] are handled by ReferenceIndex there is no need to add *_mm-tables.

Implemented as array with fields as keys and booleans as values for fast isset() lookup instead of slow in_array()

$hashVersion

Number which we can increase if a change in the code means we will have to force a re-generation of the index.

Array with information about relations

getRelations_flexFormCallBack()

Callback function for traversing the FlexForm structure in relation to finding DB references!


    public
                    getRelations_flexFormCallBack(array<string|int, mixed> $dsArr, mixed $dataValue, array<string|int, mixed> $PA, string $structurePath) : mixed

setReferenceValue()

Setting the value of a reference or removing it completely.


    public
                    setReferenceValue(string $hash, mixed $newValue[, bool $returnDataArray = false ][, bool $bypassWorkspaceAdminCheck = false ]) : string|bool|array<string|int, mixed>

Usage: For lowlevel clean up operations! WARNING: With this you can set values that are not allowed in the database since it will bypass all checks for validity! Hence it is targeted at clean-up operations. Please use DataHandler in the usual ways if you wish to manipulate references. Since this interface allows updates to soft reference values (which DataHandler does not directly) you may like to use it for that as an exception to the warning above. Notice; If you want to remove multiple references from the same field, you MUST start with the one having the highest sorting number. If you don't the removal of a reference with a lower number will recreate an index in which the remaining references in that field has new hash-keys due to new sorting numbers - and you will get errors for the remaining operations which cannot find the hash you feed it! To ensure proper working only admin-BE_USERS in live workspace should use this function

Parameters

$hash : string: 32-byte hash string identifying the record from sys_refindex which you wish to change the value for
$newValue : mixed: Value you wish to set for reference. If NULL, the reference is removed (unless a soft-reference in which case it can only be set to a blank string). If you wish to set a database reference, use the format "[table]:[uid]". Any other case, the input value is set as-is
$returnDataArray : bool = false: Return $dataArray only, do not submit it to database.
$bypassWorkspaceAdminCheck : bool = false: If set, it will bypass check for workspace-zero and admin user

Return values

string|bool|array<string|int, mixed> —

FALSE (=OK), error message string or array (if $returnDataArray is set!)

setWorkspaceId()
