Introduction ¶

There are three columns config types that do similar things but still have subtle differences between them. These are the none type, the passthrough type and the user type.

Characteristics of none:

The DataHandler discards values send for type none and never persists or updates them in the database.
Type none is the only type that does not necessarily need a database field.
Type none fields does have a default renderType in FormEngine that displays the value as readonly if a database field exists and the value can be formatted.
If no database field exists for none fields, an empty readonly input field is rendered by default.
Type none fields are designed to be not rendered at other places in the backend, for instance they can not be selected to be displayed in the list module "single table view" if everything has been configured correctly.

The none field can be useful, if:

A "virtual" field that has no database representation is needed. A simple example could be a rendered map that receives values from latitude and longitude fields but that needs to database representation itself.
A third party feeds the database field with a value and the value should be formatted and displayed in FormEngine. However, a input type with readOnly=true is usually better suited to do that.

Since the formatting part of none fields can be done with input type as well, most useful usage of type none fields is a "virtual" field that is combined with a custom renderType by an extension. The TYPO3 core makes little or no use of none fields itself.

Examples ¶

Simple none field¶

'none_1' => [
    'label' => 'none_1',
    'config' => [
        'type' => 'none',
    ],
],

cols ¶

Datatype

integer

Scope

Display

Description

Set the width of the input field. Overrides size.

Value for the width of the <input> field. To set the input field to the full width of the form area, use the value 50. Default is 30.

fieldInformation ¶

Datatype: array
Scope: Display
Description: Show information between an element label and the main element input area. Configuration works identical to the "fieldWizard" property, no default configuration in the core exists (yet). In contrast to "fieldWizard", HTML returned by fieldInformation is limited, see FormEngine docs for more details.

none ¶

Datatype

string (keyword) + array

Scope

Display

Description

The value of a none-type fields is normally displayed as is. It is however possible to format it using this property. The following keywords are available, some having sub-properties. Sub-properties are called with the format. keyword (note the trailing dot), which in itself is an array.

date

Formats the value of the field as a date. The default formatting uses PHP's date() function and d-m-Y as a format.

Possible options are:

strftime: (boolean) If true, strftime() is used instead date() for formatting.
option: (string) Format string (i.e. Y-m-d or %x, etc.).
appendAge: (boolean) If true, the age of the value is appended is appended to the formatted output.

datetime

Formats the values using PHP's date() function and H:i d-m-Y as a format.

time

Formats the values using PHP's date() function and H:i as a format.

timesec

Formats the values using PHP's date() function and H:i:s as a format.

year

Formats the values using PHP's date() function and Y as a format.

int

Formats the values as an integer using PHP's sprintf() in various bases. The default base is decimal (dec). The base is defined as an option:

base: (string) Defines the base of the value. Possible bases are "dec", "hex", "HEX", "oct" and "bin".

float

Formats the values as an real number using PHP's sprintf() and the %f marker. The number of decimals is an option:

precision: (integer) Defines the number of decimals to use (maximum is 10, default is 2).

number

Formats the values as a number using PHP's sprintf(). The format to use is an option:

option: (string) A format definition according to PHP's sprintf() function (see the reference).

md5

Returns the md5 hash of the values.

filesize

Formats the values as file size using \TYPO3\CMS\Core\Utility\GeneralUtility::formatSize(). One option exists:

appendByteSize: (boolean) If true, the original value is appended to the formatted string (between brackets).

user

Calls a user-defined function to format the values. The only option is the reference to the function:

userFunc

(string) Reference to the user-defined function. The function receives the field configuration and the field's value as parameters.

Examples

'aField' => [
    'config' => [
        'type' => 'none',
        'format' => 'date'
        'format.' => [
            'strftime' => TRUE,
            'option' => '%x'
        ],
    ],
],

'aField' => [
    'config' => [
        'type' => 'none',
        'format' => 'float'
        'format.' => [
            'precision' => 8
        ],
    ],
],

pass_content ¶

Datatype

boolean

Scope

Display

Description

If set, then content from the field is directly outputted in the <input> section as value attribute. Otherwise, the content will be passed through htmlspecialchars().

Be careful to set this flag since it allows HTML from the field to be outputted on the page, thereby creating the possibility of XSS security holes.

size ¶

Datatype

integer

Scope

Display

Description

The cols value is used to set the width of the field, and if cols is not found, then this value is used.

Value for the width of the <input> field. To set the input field to the full width of the form area, use the value 50. Default is 30.
