\nn\t3::TCA()->addModuleOptionToPage($label, $identifier, $iconIdentifier = ''); 

Add a selection option in the page properties under "Behavior -> Contains extension". Traditionally used in Configuration/TCA/Overrides/pages.php, previously in ext_tables.php

// Register the icon in ext_localconf.php (16 x 16 px SVG)
\nn\t3::Registry()->icon('icon-identifier', 'EXT:myext/Resources/Public/Icons/module.svg');

// In Configuration/TCA/Overrides/pages.php
\nn\t3::TCA()->addModuleOptionToPage('description', 'identifier', 'icon-identifier');

\nn\t3::TCA()->createConfig($tablename = '', $basics = [], $custom = []); 

Get basic configuration for the TCA. These are the fields such as hidden, starttime etc., which are always the same for (almost) all tables.

Get ALL typical fields:

'columns' => \nn\t3::TCA()->createConfig(
    'tx_myext_domain_model_entry', true,
    ['title'=>...]
)

Get only certain fields:

'columns' => \nn\t3::TCA()->createConfig(
    'tx_myext_domain_model_entry',
    ['sys_language_uid', 'l10n_parent', 'l10n_source', 'l10n_diffsource', 'hidden', 'cruser_id', 'pid', 'crdate', 'tstamp', 'sorting', 'starttime', 'endtime', 'fe_group'],
    ['title'=>...]
)

\nn\t3::TCA()->getColorPickerTCAConfig(); 

Get color picker configuration for the TCA.

\nn\t3::TCA()->getColumn($tableName = '', $fieldName = '', $useSchemaManager = false); 

Gets configuration array for a field from the TCA. Alias to \nn\t3::Db()->getColumn()

\nn\t3::TCA()->getColumn( 'pages', 'media' );

| @return array

| ➜ Go to source code of TCA::getColumn()

\nn\t3::TCA()->getColumns($tableName = '', $useSchemaManager = false); 

Gets configuration array for a table from the TCA. Alias to \nn\t3::Db()->getColumns()

\nn\t3::TCA()->getColumns( 'pages' );

| @return array

| ➜ Go to source code of TCA::getColumns()

\nn\t3::TCA()->getConfig($path = ''); 

Get a configuration from the TCA for a path. Returns a reference to the config array of the corresponding field.

\nn\t3::TCA()->getConfig('tt_content.columns.tx_mask_iconcollection');

| @return array

\nn\t3::TCA()->getConfigForType($type = '', $override = []); 

Get default configuration for various typical types in the TCA Serves as a kind of alias to write the most frequently used config arrays faster and and to be able to write them more quickly

\nn\t3::TCA()->getConfigForType( 'pid' ); // => ['type'=>'group', 'allowed'=>'pages', 'maxItems'=>1]
\nn\t3::TCA()->getConfigForType( 'contentElement' ); // => ['type'=>'group', 'allowed'=>'tt_content', 'maxItems'=>1]
\nn\t3::TCA()->getConfigForType( 'text' ); // => ['type'=>'text', 'rows'=>2, ...]
\nn\t3::TCA()->getConfigForType( 'rte' ); // => ['type'=>'text', 'enableRichtext'=>'true', ...]
\nn\t3::TCA()->getConfigForType( 'color' ); // => ['type'=>'color', ...]
\nn\t3::TCA()->getConfigForType( 'fal', 'image' ); // => ['type'=>'file', ...]

Default configurations can simply be overwritten / extended:

\nn\t3::TCA()->getConfigForType( 'text', ['rows'=>5] ); // => ['type'=>'text', 'rows'=>5, ...]

For each type, the most frequently overwritten value in the config array can also be by passing a fixed value instead of an override array:

\nn\t3::TCA()->getConfigForType( 'pid', 3 ); // => ['maxItems'=>3, ...]
\nn\t3::TCA()->getConfigForType( 'contentElement', 3 ); // => ['maxItems'=>3, ...]
\nn\t3::TCA()->getConfigForType( 'text', 10 ); // => ['rows'=>10, ...]
\nn\t3::TCA()->getConfigForType( 'rte', 'myRteConfig' ); // => ['richtextConfiguration'=>'myRteConfig', ...]
\nn\t3::TCA()->getConfigForType( 'color', '#ff6600' ); // => ['default'=>'#ff6600', ...]
\nn\t3::TCA()->getConfigForType( 'fal', 'image' ); // => [ config for the field with the key `image` ]

\nn\t3::TCA()->getFalFields($tableName = ''); 

Retrieves all field names from the TCA array that have a SysFileReference relation. For the table tt_content this would be assets, media etc.

\nn\t3::TCA()->getFalFields( 'pages' ); // => ['media', 'assets', 'image']

| @return array

\nn\t3::TCA()->getFileFieldTCAConfig($fieldName = 'media', $override = []); 

Get FAL configuration for the TCA.

Standard config incl. image cropper, link and alternative image title This setting changes regularly, which is quite an imposition given the number of parameters and their changing position in the array is quite an imposition.

\nn\t3::TCA()->setConfig($path = '', $override = []); 

Overwrite a configuration of the TCA, e.g. to overwrite a mask field with its own renderType or to change core settings in the TCA on the pages or tt_content tables.

The following example sets/overwrites the config array in the TCA under:

$GLOBALS['TCA']['tt_content']['columns']['mycol']['config'][...]

\nn\t3::TCA()->setConfig('tt_content.columns.mycol', [
    'renderType' => 'nnsiteIconCollection',
    'iconconfig' => 'tx_nnsite.iconcollection',
]);

See also \nn\t3::TCA()->setContentConfig() for a short version of this method when it comes to the table tt_content and \nn\t3::TCA()->setPagesConfig() for the table pages

| @return array

| ➜ Go to source code of TCA::setConfig()

\nn\t3::TCA()->setContentConfig($field = '', $override = [], $shortParams = NULL); 

Set or overwrite a configuration of the TCA for the table tt_content.

$GLOBALS['TCA']['tt_content']['columns']['title']['config'][...]

\nn\t3::TCA()->setContentConfig( 'header', 'text' ); // ['type'=>'text', 'rows'=>2]
\nn\t3::TCA()->setContentConfig( 'header', 'text', 10 ); // ['type'=>'text', 'rows'=>10]
