TYPO3 Content Blocks Development

Compatibility: This skill targets TYPO3 v14.x with Content Blocks 2.x. Always match the Packagist friendsoftypo3/content-blocks constraint to your Core version. For Content Blocks 1.x on TYPO3 v13 , upstream requires TYPO3 ≥ 13.4 (typo3/cms-core: ^13.4) — confirm on Packagist. Examples use TYPO3 v14 APIs and CB 2.x; adjust composer.json if upstream constraints differ.

TYPO3 API First: Always use TYPO3's built-in APIs, core features, and established conventions before creating custom implementations. Do not reinvent what TYPO3 already provides. Always verify that the APIs and methods you use exist and are not deprecated in TYPO3 v14 by checking the official TYPO3 documentation.

1. The Single Source of Truth Principle

Content Blocks is the modern approach to creating custom content types in TYPO3. It eliminates redundancy by providing a single YAML configuration that generates:

• TCA (Table Configuration Array)
• Database schema (SQL)
• TypoScript rendering
• Backend forms and previews
• Labels and translations

Why Content Blocks?

2. Installation

# Install via Composer (DDEV recommended)
ddev composer require friendsoftypo3/content-blocks

# After installation, clear caches
ddev typo3 cache:flush

Version constraint: Content Blocks 1.x requires TYPO3 ≥ 13.4 (typo3/cms-core: ^13.4 in the package). TYPO3 13.1–13.3 do not satisfy that Composer constraint.

Security Configuration (Classic Mode)

For non-composer installations, deny web access to ContentBlocks folder:

# .htaccess addition
RewriteRule (?:typo3conf/ext|typo3/sysext|typo3/ext)/[^/]+/(?:Configuration|ContentBlocks|Resources/Private|Tests?|Documentation|docs?)/ - [F]

3. Content Types Overview

Content Blocks supports four content types:

4. Folder Structure

EXT:my_sitepackage/
└── ContentBlocks/
    ├── ContentElements/
    │   └── my-hero/
    │       ├── assets/
    │       │   └── icon.svg

5. Creating Content Elements

Kickstart Command (Recommended)

# Interactive mode
ddev typo3 make:content-block

# One-liner
ddev typo3 make:content-block \
  --content-type="content-element" \
  --vendor="myvendor" \
  --name="hero-banner" \
  --title="Hero Banner" \
  --extension="my_sitepackage"

# After creation, update database
ddev typo3 cache:flush -g system
ddev typo3 extension:setup --extension=my_sitepackage

Predefined Basics (content elements)

List under basics: to pull in Core field groups: TYPO3/Header , TYPO3/Appearance , TYPO3/Links , TYPO3/Categories. See the Content Blocks basics reference.

    useExistingField: true
  - identifier: bodytext
    useExistingField: true

Full Content Element Example

# EXT:my_sitepackage/ContentBlocks/ContentElements/hero-banner/config.yaml
name: myvendor/hero-banner
group: default
description: "A full-width hero banner with image and CTA"
prefixFields: true

Frontend Template

<!-- templates/frontend.fluid.html -->
<html xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers"
      xmlns:cb="http://typo3.org/ns/TYPO3/CMS/ContentBlocks/ViewHelpers"
      data-namespace-typo3-fluid="true">

<f:asset.css identifier="hero-banner-css" href="{cb:assetPath()}/frontend.css"/>

<section class="hero-banner">
    <f:if condition="{data.hero_image}">
        <f:for each="{data.hero_image}" as="image">
            <f:image image="{image}" alt="{data.header}" class="hero-image"/>
        </f:for>
    </f:if>
    
    <div class="hero-content">
        <h1>{data.header}</h1>
        <f:if condition="{data.subheadline}">
            <p class="subheadline">{data.subheadline}</p>
        </f:if>
        
        <f:if condition="{data.cta_link}">
            <f:link.typolink parameter="{data.cta_link}" class="btn btn-primary">
                {data.cta_text -> f:or(default: 'Learn more')}
            </f:link.typolink>
        </f:if>
    </div>
</section>
</html>

Backend Preview Template

<!-- templates/backend-preview.fluid.html -->
<html xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers"
      xmlns:be="http://typo3.org/ns/TYPO3/CMS/Backend/ViewHelpers"
      data-namespace-typo3-fluid="true">

<div class="content-block-preview">
    <strong>{data.header}</strong>
    <f:if condition="{data.subheadline}">
        <br/><em>{data.subheadline}</em>
    </f:if>
    <f:if condition="{data.hero_image}">
        <f:for each="{data.hero_image}" as="image">
            <be:thumbnail image="{image}" width="100" height="100"/>
        </f:for>
    </f:if>
</div>
</html>

6. Creating Record Types (Custom Tables)

Record Types create custom database tables for structured data like teams, products, events, etc.

Extbase-Compatible Table Naming

IMPORTANT: For Extbase compatibility, use the tx_extensionkey_domain_model_* naming convention:

# ✅ CORRECT - Extbase compatible table name
name: myvendor/team-member
table: tx_mysitepackage_domain_model_teammember
labelField: name
fields:
  - identifier: name
    type: Text
  - identifier: position
    type: Text
  - identifier: email
    type: Email
  - identifier: photo
    type: File
    allowed: common-image-types
    maxitems: 1



# ❌ WRONG - Short table names don't work with Extbase
name: myvendor/team-member
table: team_member  # Won't work with Extbase!

Minimal Record Type

# EXT:my_sitepackage/ContentBlocks/RecordTypes/team-member/config.yaml
name: myvendor/team-member
table: tx_mysitepackage_domain_model_teammember
labelField: name
fields:
  - identifier: name
    type: Text

Full Record Type Example

# EXT:my_sitepackage/ContentBlocks/RecordTypes/team-member/config.yaml
name: myvendor/team-member
table: tx_mysitepackage_domain_model_teammember
labelField: name
fallbackLabelFields:
  - email
languageAware: true
workspaceAware: true
sortable: true
softDelete: true
trackCreationDate: true
trackUpdateDate: true
internalDescription: true
restriction:
  disabled: true
  startTime: true
  endTime: true
  userGroup: true  # fe_group visibility fields when applicable
security:
  ignorePageTypeRestriction: true  # Allow on normal pages
fields:
  - identifier: name
    type: Text
    required: true
  - identifier: position
    type: Text
  - identifier: email
    type: Email
  - identifier: phone
    type: Text
  - identifier: bio
    type: Textarea
    enableRichtext: true
  - identifier: photo
    type: File
    allowed: common-image-types
    maxitems: 1
  - identifier: social_links
    type: Collection
    labelField: platform
    fields:
      - identifier: platform
        type: Select
        renderType: selectSingle
        items:
          - label: LinkedIn
            value: linkedin
          - label: Twitter/X
            value: twitter
          - label: GitHub
            value: github
      - identifier: url
        type: Link

Record Type options (reference)

Content Blocks exposes many optional root keys on record types — always confirm names against the current Record Types YAML reference. Commonly used flags include:

Multi-Type Records (Single Table Inheritance)

Create multiple types for one table:

# EXT:my_sitepackage/ContentBlocks/RecordTypes/person-employee/config.yaml
name: myvendor/person-employee
table: tx_mysitepackage_domain_model_person
typeField: person_type
typeName: employee
priority: 0  # Integer ordering; higher values load first (higher priority)
labelField: name
languageAware: false
workspaceAware: false
fields:
  - identifier: name
    type: Text
  - identifier: department
    type: Text



# EXT:my_sitepackage/ContentBlocks/RecordTypes/person-contractor/config.yaml
name: myvendor/person-contractor
table: tx_mysitepackage_domain_model_person
typeName: contractor
fields:
  - identifier: name
    type: Text
  - identifier: company
    type: Text
  - identifier: contract_end
    type: DateTime

Record Types as Collection Children

Define a record that can be used in IRRE collections:

# EXT:my_sitepackage/ContentBlocks/RecordTypes/slide/config.yaml
name: myvendor/slide
table: tx_mysitepackage_domain_model_slide
labelField: title
fields:
  - identifier: title
    type: Text
  - identifier: image
    type: File
    maxitems: 1
  - identifier: link
    type: Link



# EXT:my_sitepackage/ContentBlocks/ContentElements/slider/config.yaml
name: myvendor/slider
fields:
  - identifier: slides
    type: Collection
    foreign_table: tx_mysitepackage_domain_model_slide
    shareAcrossTables: true
    shareAcrossFields: true
    minitems: 1

7. Creating Page Types (Custom doktypes)

Page Types extend the pages table with custom page types – ideal for blog articles, landing pages, news pages, or other page variants with special properties.

When to Use Page Types

Minimal Page Type

# EXT:my_sitepackage/ContentBlocks/PageTypes/blog-article/config.yaml
name: myvendor/blog-article
typeName: 1705234567
fields:
  - identifier: author_name
    type: Text

Full Page Type Example

# EXT:my_sitepackage/ContentBlocks/PageTypes/blog-article/config.yaml
name: myvendor/blog-article
typeName: 1705234567   # Unix timestamp (unique identifier)
group: default         # Options: default, link, special
fields:
  - identifier: author_name
    type: Text
    label: Author
    required: true
  - identifier: teaser_text
    type: Textarea
    label: Teaser
  - identifier: hero_image
    type: File
    allowed: common-image-types
    maxitems: 1
  - identifier: publish_date
    type: DateTime
    label: Publish Date
  - identifier: reading_time
    type: Number
    label: Reading Time (minutes)

Page Type Options

Reserved typeName values: 199, 254 (cannot be used)

Icons for Page States

Page Types support state-specific icons. Add these to your assets folder:

ContentBlocks/PageTypes/blog-article/
├── assets/
│   ├── icon.svg              # Default icon
│   ├── icon-hide-in-menu.svg # Hidden in menu state
│   └── icon-root.svg         # Site root state
└── config.yaml

Backend Preview

Create a backend-preview.fluid.html to preview custom page properties:

<!-- templates/backend-preview.fluid.html -->
<html xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers"
      xmlns:be="http://typo3.org/ns/TYPO3/CMS/Backend/ViewHelpers"
      data-namespace-typo3-fluid="true">

<div class="card card-size-medium">
    <div class="card-body">
        <be:link.editRecord uid="{data.uid}" table="{data.mainType}" fields="author_name">
            <strong>Author:</strong> {data.author_name}
        </be:link.editRecord>
        <f:if condition="{data.publish_date}">
            <br/><small>Published: <f:format.date format="d.m.Y">{data.publish_date}</f:format.date></small>
        </f:if>
    </div>
</div>
</html>

Frontend Integration

Page Types have no automatic frontend rendering. Add the ContentBlocksDataProcessor to your TypoScript:

# Configuration/TypoScript/setup.typoscript
page = PAGE
page {
    10 = FLUIDTEMPLATE
    10 {
        templateName = Default
        templateRootPaths.10 = EXT:my_sitepackage/Resources/Private/Templates/
        
        dataProcessing {
            # Process Content Blocks page data
            1 = content-blocks
        }
    }
}

Then access fields in your Fluid template:

<!-- Resources/Private/Templates/Default.html -->
<f:if condition="{data.author_name}">
    <p class="author">By {data.author_name}</p>
</f:if>

<f:if condition="{data.hero_image}">
    <f:for each="{data.hero_image}" as="image">
        <f:image image="{image}" class="hero-image"/>
    </f:for>
</f:if>

Remove from Page Tree Drag Area

To hide your page type from the "Create new page" drag area:

# Configuration/user.tsconfig
options {
    pageTree {
        doktypesToShowInNewPageDragArea := removeFromList(1705234567)
    }
}

8. Creating File Types (Extended Metadata)

New in version 1.2

File Types extend the sys_file_reference table with custom fields – perfect for photographer credits, copyright notices, or additional reference-level options.

Available File Type Names

Minimal File Type

# EXT:my_sitepackage/ContentBlocks/FileTypes/image-extended/config.yaml
name: myvendor/image-extended
typeName: image
fields:
  - identifier: photographer
    type: Text
    label: Photographer

Full File Type Example

# EXT:my_sitepackage/ContentBlocks/FileTypes/image-extended/config.yaml
name: myvendor/image-extended
typeName: image
prefixFields: false  # Keep original column names
fields:
  - identifier: image_overlay_palette
    type: Palette
    label: 'LLL:EXT:core/Resources/Private/Language/locallang_tca.xlf:sys_file_reference.imageoverlayPalette'
    fields:
      # Reuse existing TYPO3 core fields
      - identifier: alternative
        useExistingField: true
      - identifier: description
        useExistingField: true
      - type: Linebreak
      - identifier: link
        useExistingField: true
      - identifier: title
        useExistingField: true
      - type: Linebreak
      # Custom fields
      - identifier: photographer
        type: Text
        label: Photographer
      - identifier: copyright
        type: Text
        label: Copyright Notice
      - identifier: source_url
        type: Link
        label: Source URL
      - type: Linebreak
      - identifier: crop
        useExistingField: true

File Type Options

Use Cases for File Types

Accessing File Type Fields

In Fluid templates, access custom metadata through FAL references:

<f:for each="{data.images}" as="image">
    <figure>
        <f:image image="{image}" alt="{image.alternative}"/>
        <f:if condition="{image.properties.photographer}">
            <figcaption>
                Photo: {image.properties.photographer}
                <f:if condition="{image.properties.copyright}">
                    | © {image.properties.copyright}
                </f:if>
            </figcaption>
        </f:if>
    </figure>
</f:for>

9. Field Types Reference

Simple Fields

Relational Fields

Structural Fields

Common Field Options

fields:
  - identifier: my_field
    type: Text
    label: My Field Label           # Static label (or use labels.xlf)
    description: Help text          # Field description
    required: true                  # Make field required
    default: "Default value"        # Default value
    placeholder: "Enter text..."    # Placeholder text
    prefixField: false              # Disable prefixing for this field
    useExistingField: true          # Reuse existing TCA field
    displayCond: 'FIELD:other:=:1'  # Conditional display
    onChange: reload                # Reload form on change

File Field Example

TCA-only options: Keys like appearance / behaviour belong in generated TCA, not always in Content Blocks YAML. If the schema rejects them, add a TCA override for that field after generation (see Content Blocks docs on extending TCA).

fields:
  - identifier: gallery_images
    type: File
    allowed: common-image-types
    minitems: 1
    maxitems: 10

Select Field Example

fields:
  - identifier: layout
    type: Select
    renderType: selectSingle
    default: default
    items:
      - label: Default Layout
        value: default
      - label: Wide Layout
        value: wide
      - label: Compact Layout
        value: compact

Collection Field Example (Inline IRRE)

fields:
  - identifier: accordion_items
    type: Collection
    labelField: title
    minitems: 1
    maxitems: 20
    appearance:
      collapseAll: true
      levelLinksPosition: both
    fields:
      - identifier: title
        type: Text
        required: true
      - identifier: content
        type: Textarea
        enableRichtext: true
      - identifier: is_open
        type: Checkbox
        label: Initially Open

10. Field Prefixing

Content Blocks automatically prefixes field identifiers to avoid collisions.

Prefixing Types

# Full prefix (default): myvendor_myblock_fieldname
name: myvendor/my-block
prefixFields: true
prefixType: full

# Vendor prefix only: myvendor_fieldname
name: myvendor/my-block
prefixFields: true
prefixType: vendor

# Custom vendor prefix: tx_custom_fieldname
name: myvendor/my-block
prefixFields: true
prefixType: vendor
vendorPrefix: tx_custom

# No prefix (use with caution!)
name: myvendor/my-block
prefixFields: false

Disable Prefixing per Field

fields:
  - identifier: my_custom_field
    type: Text
    prefixField: false  # This field won't be prefixed

11. Templating Features

Accessing Data in Fluid

<!-- Basic field access -->
{data.header}
{data.my_field}

<!-- Record metadata -->
{data.uid}
{data.pid}
{data.languageId}
{data.mainType}      <!-- Table name: tt_content -->
{data.recordType}    <!-- CType: myvendor_heroblock -->
{data.fullType}      <!-- tt_content.myvendor_heroblock -->

<!-- Raw database values -->
{data.rawRecord.some_field}

<!-- System properties -->
{data.systemProperties.createdAt}
{data.systemProperties.lastUpdatedAt}
{data.systemProperties.sorting}
{data.systemProperties.disabled}

<!-- Language info -->
{data.languageInfo.translationParent}
{data.languageInfo.translationSource}

<!-- Relations are auto-resolved! -->
<f:for each="{data.gallery_images}" as="image">
    <f:image image="{image}" width="400"/>
</f:for>

<!-- Nested collections -->
<f:for each="{data.accordion_items}" as="item">
    <h3>{item.title}</h3>
    <f:format.html>{item.content}</f:format.html>
</f:for>

Asset ViewHelpers

<!-- Include CSS from assets folder -->
<f:asset.css identifier="my-block-css" href="{cb:assetPath()}/frontend.css"/>

<!-- Include JS from assets folder -->
<f:asset.script identifier="my-block-js" src="{cb:assetPath()}/frontend.js"/>

<!-- Cross-block asset reference -->
<f:asset.css identifier="shared-css" href="{cb:assetPath(name: 'vendor/other-block')}/shared.css"/>

Translation ViewHelper

<!-- Access labels.xlf translations -->
<f:translate key="{cb:languagePath()}:my_label"/>

<!-- Cross-block translation -->
<f:translate key="{cb:languagePath(name: 'vendor/other-block')}:shared_label"/>

12. Extending Existing Tables

Add custom types to existing tables (like tx_news):

# EXT:my_sitepackage/ContentBlocks/RecordTypes/custom-news/config.yaml
name: myvendor/custom-news
table: tx_news_domain_model_news
typeName: custom_news
fields:
  - identifier: title
    useExistingField: true
  - identifier: custom_field
    type: Text

13. Workflow with DDEV

Standard Development Workflow

# 1. Create new Content Block
ddev typo3 make:content-block

# 2. Clear system caches
ddev typo3 cache:flush -g system

# 3. Update database schema
ddev typo3 extension:setup --extension=my_sitepackage

# Alternative: Use Database Analyzer in TYPO3 Backend
# Admin Tools > Maintenance > Analyze Database Structure

Using webprofil/make Extension

If webprofil/make is installed:

# Create Content Block with webprofil/make
ddev make:content_blocks

# Clear caches and update database (prefer Core CLI)
ddev typo3 cache:flush
ddev typo3 extension:setup --extension=my_sitepackage
# `database:updateschema` exists only with helhum/typo3-console — do not assume it in plain Core projects

Integration with Extbase

After creating Record Types with proper table names, generate Extbase models:

# If typo3:make:model is available
ddev typo3 make:model --extension=my_sitepackage

# Generate repository
ddev typo3 make:repository --extension=my_sitepackage

14. Defaults Configuration

Create a content-blocks.yaml in project root for default settings:

# content-blocks.yaml
vendor: myvendor
extension: my_sitepackage
content-type: content-element
skeleton-path: content-blocks-skeleton

config:
  content-element:
    basics:
      - TYPO3/Header
      - TYPO3/Appearance
      - TYPO3/Links
      - TYPO3/Categories
    group: default
    prefixFields: true
    prefixType: full
  
  record-type:
    prefixFields: true
    prefixType: vendor
    vendorPrefix: tx_mysitepackage

15. Best Practices

DO ✅

1. Use Extbase-compatible table names for Record Types:

   table: tx_myextension_domain_model_myrecord

2. Reuse existing fields when possible:

   • identifier: header useExistingField: true

3. Group related fields with Tabs and Palettes:

   • identifier: settings_tab type: Tab label: Settings

4. Use meaningful identifiers (snake_case):

   • identifier: hero_background_image

5. Clear caches after changes :

   ddev typo3 cache:flush -g system ddev typo3 extension:setup --extension=my_sitepackage

6. Use labels.xlf for all user-facing labels

DON'T ❌

1. Don't use raw SQL - Content Blocks generates schema automatically

2. Don't duplicate TCA - Config.yaml is the single source of truth

3. Don't use short table names for Extbase integration:

   ❌ Wrong

table: team_member

# ✅ Correct
table: tx_mysitepackage_domain_model_teammember

4. Don't use dashes in identifiers :

    # ❌ Wrong
identifier: hero-image

# ✅ Correct
identifier: hero_image

5. Don't forget shareAcross options when using foreign_table in multiple places

16. Troubleshooting

Content Block Not Appearing

# Clear all caches
ddev typo3 cache:flush

# Rebuild class loading
ddev composer dump-autoload

# Check extension setup
ddev typo3 extension:setup --extension=my_sitepackage

Database Errors

# Update database schema (Core)
ddev typo3 extension:setup --extension=my_sitepackage
# With typo3-console only: ddev typo3 database:updateschema

# Or use Compare Tool
# Admin Tools > Maintenance > Analyze Database Structure

Field Not Saving

• Check field identifier is unique (use prefixing)
• Verify field type is correct
• Check for typos in config.yaml
• Ensure labels.xlf has matching keys

17. Version constraints

Use TYPO3 v14.1+ with Content Blocks 2.x (friendsoftypo3/content-blocks currently requires typo3/cms-core: ^14.1 — confirm on Packagist).

// ext_emconf.php — TYPO3 v14.1+ + Content Blocks 2.x
'depends' => [
    'typo3' => '14.1.0-14.99.99',
    'content_blocks' => '2.0.0-2.99.99',
],

18. Package Management for v14 Compatibility

If extensions don't support TYPO3 v14 yet, fork and update:

# Add private fork as VCS repository in composer.json
# Then update extension for v14 using typo3-rector and typo3-update skills

Required private forks for webconsulting stack:

• webprofil/wp-t3monitoring-client (^13 → ^14)
• webprofil/deployer (^13 → ^14)
• webprofil/crawler (^1.0 → compatible with v14)
• webprofil/make (^1.1 → compatible with v14)

v14-Only Changes

The following changes affect Content Blocks development on TYPO3 v14 only.

New TCA Type country [v14 only]

TYPO3 v14 introduces a native country TCA type (#99911). Content Blocks can use this for country selection fields. Check Content Blocks YAML documentation for support of this field type.

TCA itemsProcessors [v14 only]

New itemsProcessors option (#107889) enables dynamic item generation for select fields. Content Blocks may expose this via YAML configuration for advanced select field customization.

Type-Specific TCA Properties [v14 only]

• Type-specificctrl properties (#108027) — title, label, and other ctrl properties can now be overridden per record type in the types section.
• Type-specific TCA defaults (#107281) — default values can differ per record type.

Fluid 5.0 Strict Types [v14 only]

Content Block Fluid templates must comply with Fluid 5.0 strict typing:

• ViewHelper arguments are strictly typed. Ensure correct types (int vs string).
• No underscore-prefixed variable names (_myVar).
• CDATA sections are preserved (not stripped).

Content Element Restrictions per Column [v14.1+ only]

TYPO3 v14.1 integrates content_defender functionality into Core. Backend layouts can now restrict which Content Elements (including Content Blocks) are allowed per colPos without third-party extensions.
