Feature: #97193 - New TCA type "number"

Description

Especially TCA type input has a wide range of use cases, depending on the configured renderType and the eval options. Determination of the semantic meaning is therefore usually quite hard and often leads to duplicated checks and evaluations in custom extension code.

In our effort of introducing dedicated TCA types for all those use cases, the TCA type number has been introduced. It replaces the eval=int and eval=double2 options of TCA type input.

The TCA number fields will be rendered with the html type attribute set to number.

The TCA type number features the following column configuration:

autocomplete
behaviour: allowLanguageSynchronization
default
fieldControl
fieldInformation
fieldWizard
format: integer, decimal
mode
nullable
placeholder
range: lower, upper
readOnly
required
search
size
slider: step, width
valuePicker: items, mode

The following column configuration can be overwritten by page TSconfig:

readOnly
size

The TCA type number introduces the new configuration format, which can be set to decimal or integer, which is the default.

Note

The slider option allows to define a visual slider element next to the input field. The steps can be defined with the step option. The minimum and maximum value can be configured with the range[lower] and range[upper] options.

Note

The valuePicker option allows to define default values via items. With mode, one can define how the selected value should be added (replace, prepend or append).

Note

The options range, slider as well as eval=double2 are no longer evaluated for TCA type input.

Migration

The migration from eval='int' to type=number is done like following:

// Before

'int_field' => [
    'label' => 'Int field',
    'config' => [
        'type' => 'input',
        'eval' => 'int',
    ]
]

// After

'int_field' => [
    'label' => 'Int field',
    'config' => [
        'type' => 'number',
    ]
]

The migration from eval=double2 to type=number is done like following:

// Before

'double2_field' => [
    'label' => 'double2 field',
    'config' => [
        'type' => 'input',
        'eval' => 'double2',
    ]
]

// After

'double2_field' => [
    'label' => 'double2 field',
    'config' => [
        'type' => 'number',
        'format' => 'decimal'
    ]
]

An automatic TCA migration is performed on the fly, migrating all occurrences to the new TCA type and triggering a PHP E_USER_DEPRECATED error where code adoption has to take place.

Impact

It's now possible to simplify the TCA configuration by using the new dedicated TCA type number. Setting the new format option to decimal behaves like the former eval=double2.
