About this extension

TYPO3's out of the box configuration options to change the way editors interact with content are impressive and cover almost all use cases we encounter in our daily work. Changing backend forms for example for content element types globally or for a specific content element type is a breeze — you can just override global TCA settings. Changing some other elements, like a field label, hiding a specific field in a specific content element type within just parts of your TYPO3 instance (whether for one of your page trees or a part of a larger page tree) is easy to do using Page TsConfig.

Sometimes, though, you might want some more options than ship with TYPO3 core. At least we do from time to time. For advanced use cases we created (and use) this extension.

This extension enables advanced configuration options using Page TsConfig for special use cases.

Use cases for this extension

Changing configuration for a field

Sometimes you might need to adjust configuration for a field for parts of your TYPO3 page tree, like when working with multi-site setups. You can change the configuration for the header field using:

TCEFORM.tt_content.header.config.type = text
TCEFORM.tt_content.header.config.rows = 2

This also works for certain the types only:

TCEFORM.tt_content.header.types.my_example_type.config.type = text
TCEFORM.tt_content.header.types.my_example_type.config.rows = 3
TCEFORM.tt_content.header.types.my_example_type.config.cols = 25

Changing configuration for inline fields

Depending on your frontend design your "Element Component 1" might feature an image with a full palette of fields for meta data - alt text, title text, a link etc. For parts of your page tree, though, the element uses a different frontend template and some of these fields are ignored. Your editor might be confused about a "link" field, that does not do anything. Here's how to change a showitem configuration for an inline field:

TCEFORM.tt_content {
  image.types.component-1.config.overrideChildTca.types.2.showitem = --palette--;;basicImageoverlayPalette, --palette--;;filePalette
}

Changing crop variants using PageTS

We maintain TYPO3 instances with multiple websites using a common set of templates and content element types. We normally set fixed cropVariants for all image assets an editor can use in a specific element if the design calls for a specific aspect ratio; often times more than one, depending on the design.

Sometimes we have a set of teaser elements in such a template package, the default ratio for this element's image is 4:3, but for some reason two out of your 70 websites built upon that template package use a design slightly different and want to have a 16:9 image ratio for that specific element.

This extension enables the use of Page TsConfig to alter available cropVariant settings:

TCEFORM.tt_content.image.types.my_example_teaser.config.overrideChildTca.columns.crop.config.cropVariants {
  default {
    allowedAspectRatios.default.title = 16:9
    allowedAspectRatios.default.value = 1.77
    selectedRatio = default
  }
}

Depending on our use case we can change a setting for an existing named cropVariant, or add a new one — sometimes there's no cropVariant set globally to begin with (and we set everything using PageTS), sometimes there's the need to change on part.

This is also possible for inline records, their values and their respective settings (tx_listelements_list being an inline element created using EXT:listelements):

TCEFORM.tt_content {
  tx_listelements_list.types.timeline.config.overrideChildTca.columns.images.config.overrideChildTca.columns.crop.config.cropVariants {
    default.title = My new title
    allowedAspectRatios.1:1.title = 1:1
    allowedAspectRatios.1:1.value = 1
    selectedRatio = 1:1
  }
}

Changing palette configuration

Sometimes it makes sense to rearrange fields in the backend within a palette for one of your page trees, for example because it helps the editor to better recognize the connection between the backend form and the frontend design. It is possible using Page TsConfig to change settings for palettes:

# move the "media" field from example-palette-2 to example-palette-1
TCEFORM.tt_content {
  palettes.types.startpage-header.startpage-header-media.label = Custom palette title
  palettes.types.startpage-header.startpage-header-media.showitem = image, --linebreak--, media
  # an empty palette will not be shown at all
  palettes.types.startpage-header.startpage-header-media-desktop.showitem =
}

Important note: While you can mess with the order of fields that way, you cannot add a field entirely. The TCA showitem configuration determines which fields are available for your backend form; you might need to add a field globally, remove it globally and enable it for a specific page tree depending on your use case.

When to not use this extension

If you want to change some setting for some backend form globally, always put your configuration in TCA/Overrides!
