allowNonIdValues

allowNonIdValues
Type
boolean
Path
$GLOBALS['TCA'][$table]['columns'][$field]['config']
Scope
Proc.
RenderType
all

Only useful if foreign_table is enabled.

If set, then values which are not integer ids will be allowed. May be needed if you use itemsProcFunc or just enter additional items in the items array to produce some string-value elements for the list.

authMode

authMode
Type
string (keyword)
Path
$GLOBALS['TCA'][$table]['columns'][$field]['config']
Scope
Display / Proc.
RenderType
all

Authorization mode for the selector box. The only possible option is:

explicitAllow
All static values from the "items" array of the selector box will be added to a matrix in the backend user configuration where a value must be explicitly selected if a user (other than admin) is allowed to use it!)
Migration: Using authMode='explicitDeny'

The "deny list" approach for single field values has been removed, the only allowed option for authMode is explicitAllow. Extensions using config value explicitDeny should be adapted to switch to explicitAllow instead. The upgrade wizard "Migrate backend groups "explicit_allowdeny" field to simplified format." that transfers existing be_groups rows to the new format, drops any DENY fields and instructs admins to not set new access rights of affected backend groups.

Migration: Using authMode='individual'

Handling of authMode being set to individual has been fully dropped. The Core provides no alternative. This has been an obscure setting ever since and there is no direct migration. Extensions that rely on this handling need to find a substitution based on Core hooks, Core events or other existing Core API functionality.

allowLanguageSynchronization

allowLanguageSynchronization
Type
boolean
Default
false
Path
$GLOBALS['TCA'][$table]['columns'][$field]['config']['behaviour']['allowLanguageSynchronization']
Scope
Proc.

Allows an editor to select in a localized record whether the value is copied over from default or source language record, or if the field has an own value in the localization. If set to true and if the table supports localization and if a localized record is edited, this setting enables FieldWizard LocalizationStateSelector: Two or three radio buttons shown below the field input. The state of this is stored in a json encoded array in the database table called l10n_state. It tells the DataHandler which fields of the localization records should be kept in sync if the underlying default or source record changes.

Type
integer

Scope
Proc.

New in version 13.0

The TCA config option dbFieldLength contains an integer value that is applied to varchar fields (not text) and defines the length of the database field. It will not be respected for fields that resolve to an integer type. Developers who wish to optimize field length can use dbFieldLength for type=select fields to increase or decrease the default length.

Example: Increase the dbFieldLength for a select field

Type

Path

Scope
Proc. / Display
RenderType
all

The items from foreign_table are selected with this WHERE clause. The WHERE clause is effectively appended to the existing WHERE clause (which contains default constraints, such as NOT deleted) and must begin with AND.

Field quoting

The example below uses the special field quoting syntax {#...} around identifiers to be as DBAL-compatible as possible. Note that ORDER BY and GROUP BY should NOT be quoted, since they always receive proper quoting automatically through the API.

Markers inside the WHERE statement

It is possible to use markers in the WHERE clause:

###REC_FIELD_[field name]###

Any field of the current record.

###THIS_UID###
Current element uid (zero if new).
###CURRENT_PID###
The current page id (pid of the record).

###SITEROOT###

###PAGE_TSCONFIG_ID###
A value you can set from Page TSconfig dynamically.
###PAGE_TSCONFIG_IDLIST###
A value you can set from Page TSconfig dynamically.
###PAGE_TSCONFIG_STR###
A value you can set from Page TSconfig dynamically.
###SITE:<KEY>.<SUBKEY>###
A value from the site configuration, for example: ###SITE:mySetting.categoryPid### or ###SITE:rootPageId###.

The markers are preprocessed so that the value of CURRENT_PID and PAGE_TSCONFIG_ID are always integers (default is zero), PAGE_TSCONFIG_IDLIST will always be a comma-separated list of integers (default is zero) and PAGE_TSCONFIG_STR will be quoted before substitution (default is blank string).

More information about markers set by Page TSconfig can be found in the TSconfig reference.

items

items
Type
array
Path
$GLOBALS['TCA'][$table]['columns'][$field]['config']
Scope
Display / Proc.
RenderType
all

Contains the elements for the selector box unless the property foreign_table or special has been set in which case automated values are set in addition to any values listed in this array.

For examples see also property items of singleSelect.

itemsProcFunc

itemsProcFunc
Type
string (class->method reference)
Path
$GLOBALS['TCA'][$table]['columns'][$field]['config']
Scope
Display / Proc.

PHP method which is called to fill or manipulate the items array. See itemsProcFunc about details.

localizeReferencesAtParentLocalization

localizeReferencesAtParentLocalization
Type
boolean
Path
$GLOBALS['TCA'][$table]['columns'][$field]['config']
Scope
Proc.

Defines whether referenced records should be localized when the current record gets localized. This only applies if references are not stored using MM tables.

maxitems

maxitems
Type
integer > 0
Path
$GLOBALS['TCA'][$table]['columns'][$field]['config']
Scope
Display / Proc.

Maximum number of child items. Defaults to a high value. JavaScript record validation prevents the record from being saved if the limit is not satisfied.

minitems

minitems
Type
integer > 0
Path
$GLOBALS['TCA'][$table]['columns'][$field]['config']
Scope
Display

Minimum number of child items. Defaults to 0. JavaScript record validation prevents the record from being saved if the limit is not satisfied.

MM

MM
Type
string (table name)
Path
$GLOBALS['TCA'][$table]['columns'][$field]['config']
Scope
Proc.

This value contains the name of the table in which to store a MM relation. It is used together with foreign_table.

The database field with a MM property only stores the number of records in the relation.

Please have a look into the additional information in the MM common property description.

MM_match_fields

MM_match_fields
Type
array
Path
$GLOBALS['TCA'][$table]['columns'][$field]['config']
Scope
Display / Proc.

Array of field => value pairs to both insert and match against when writing/reading MM relations.

MM_opposite_field

MM_opposite_field
Type
string (field name)
Path
$GLOBALS['TCA'][$table]['columns'][$field]['config']
Scope
Proc.

If you want to make a MM relation editable from the foreign side (bidirectional) of the relation as well, you need to set MM_opposite_field on the foreign side to the field name on the local side.

For example, if the field companies.employees is your local side and you want to make the same relation editable from the foreign side of the relation in a field called persons.employers, you would need to set the MM_opposite_field value of the TCA configuration of the persons.employers field to the string "employees".

MM_oppositeUsage

MM_oppositeUsage
Type
array
Path
$GLOBALS['TCA'][$table]['columns'][$field]['config']
Scope
Proc.

In a MM bidirectional relation using match fields the opposite side needs to know about the match fields for certain operations (for example, when a copy is created in a workspace) so that relations are carried over with the correct information.

MM_oppositeUsage is an array which references which fields contain the references to the opposite side, so that they can be queried for match field configuration.

MM_table_where

MM_table_where
Type
string (SQL WHERE)
Path
$GLOBALS['TCA'][$table]['columns'][$field]['config']
Scope
Proc.

Additional where clause used when reading MM relations.

Example:

{#uid_local} = ###THIS_UID###
Copied!

The above example uses the special field quoting syntax {#...} around identifiers to be as DBAL-compatible as possible.

MM_hasUidField

MM_hasUidField

Changed in version 13.0

This setting is obsolete. Remove all occurrences of MM_hasUidField from TCA. The uid column is added as primary key automatically, if multiple = true is set, otherwise a combined primary key of fields uid_local, uid_foreign plus eventually tablenames and fieldname is used.

multiple

multiple
Type
boolean
Path
$GLOBALS['TCA'][$table]['columns'][$field]['config']
Scope
Display / Proc.

Allows the same item more than once in a list.

If used with bidirectional MM relations it must be set for both the native and foreign field configuration.

Changed in version 13.0

The property MM_hasUidField is obsolete. It had to be defined previously when using multiple.
