Templating 

Accessing variables 

Inside your frontend.html or backend-preview.html file you can access the properties of your Content Element as usual by the {data} variable. This variable, however, is special. It has real superpowers!

In contrast to the usual array, we are dealing with an object here. This allows us to magically access our own custom properties very easily. Normally you would access the processed properties. This is done by simply accessing the desired property like {data.header}. The raw properties have to be accessed by {data.rawRecord.some_field}.

All fields with relations are resolved automatically to an array. This includes Collection, Select, Relation, File, Folder, Category and FlexForm fields. There is no need to provide additional DataProcessors for them. Content Blocks applies relation resolving for you (recursively!).

Have a look at this code example to grasp what's possible:

<!-- Any property, which is available in the Record (like normal) -->
{data.title}
{data.uid}
{data.pid}

<!-- Normal access to custom relational properties -->
<f:for each="{data.collection1}" as="item">{item.title}</f:for>

<!-- Recursive access to custom relational properties -->
<f:for each="{data.collection1}" as="item">
    <f:for each="{item.categories}" as="category">
        {category.title}
    </f:for>
</f:for>

<!-- Language related properties -->
{data.languageId}
{data.languageInfo.translationParent}
{data.languageInfo.translationSource}

<!-- The overlaid uid -->
{data.overlaidUid}

<!-- Types are a combination of the table name and the Content Type name. -->
<!-- Example for table "tt_content" and CType "textpic": -->

<!-- "tt_content" (this is basically the table name) -->
{data.mainType}

<!-- "textpic" (this is the CType) -->
{data.recordType}

<!-- "tt_content.textpic" (Combination of mainType and record type, separated by a dot) -->
{data.fullType}

<!-- System related properties -->
{data.systemProperties.deleted}
{data.systemProperties.disabled}
{data.systemProperties.lockedForEditing}
{data.systemProperties.createdAt}
{data.systemProperties.lastUpdatedAt}
{data.systemProperties.publishAt}
{data.systemProperties.publishUntil}
{data.systemProperties.userGroupRestriction}
{data.systemProperties.sorting}
{data.systemProperties.description}

<!-- Computed properties depending on the request context -->
{data.computedProperties.versionedUid}
{data.computedProperties.localizedUid}
{data.computedProperties.requestedOverlayLanguageId}
{data.computedProperties.translationSource} <!-- Only for pages, contains the Page model -->

<!-- Workspace related properties -->
{data.versionInfo.workspaceId}
{data.versionInfo.liveId}
{data.versionInfo.state.name}
{data.versionInfo.state.value}
{data.versionInfo.stageId}

<!-- To access the raw (unprocessed) database record use `rawRecord` -->
{data.rawRecord.some_field}

Frontend & backend 

Content Blocks allows you to provide a separate template for the frontend and the backend out of the box. The variables are the same for both templates, and while using the asset ViewHelpers, you can also ship JavaScript and CSS as you need. The main goal behind this is, that you can provide a better user experience for the editors. With this feature, there is the possibility to provide nearly the same layout in the frontend and the backend, so the editors easily find the element they want to edit.

The frontend template is located in templates/frontend.html and the backend template in templates/backend-preview.html.

Asset ViewHelpers 

Content Blocks provides a new AssetPathViewHelper to access assets from within the current Content Block in the template.

<f:comment><!-- Include the assets/frontend.css stylesheet --></f:comment>
<f:asset.css identifier="myCssIdentifier" href="{cb:assetPath()}/frontend.css"/>

<f:comment><!-- Include the assets/frontend.js script --></f:comment>
<f:asset.script identifier="myJavascriptIdentifier" src="{cb:assetPath()}/frontend.js"/>

Alternatively, you can set name manually.

<f:comment><!-- The name of the Content Block is set explicitly --></f:comment>
<f:asset.script identifier="myJavascriptIdentifier" href="{cb:assetPath(name: 'vendor/name')}/frontend.js"/>

LanguagePath ViewHelper 

Content Blocks provides a LanguagePathViewHelper to retrieve the LLL-path for the labels.xlf file of the current Content Block.

<f:translate key="{cb:languagePath()}:header"/>

You can also set name manually:

<f:translate key="{cb:languagePath(name: 'vendor/name')}:header"/>

Partials 

Partials are a very useful feature of Fluid. You can use them to split up your templates into smaller parts. If you want to use a partial in a Content Block, you can create a subdirectory partials in the templates directory and place your partials there.

This part is automatically added, but you can also extend or overwrite this TypoScript configuration in your sitepackage.

• Shared partials

Layouts 

Analogous to partials, you can also use layouts. You can create a subdirectory layouts in the templates directory and place your layouts there. The configuration is added automatically, but you can also extend or overwrite the TypoScript configuration in your sitepackage. Afterwards you can use your layouts as usual in Fluid.

Shareable resources 

There is the technical possibility to use resources from the whole TYPO3 setup (e.g. translations, scripts, or partials from other extensions), but we do not recommend to do so. Content Blocks are intended to work independent of external resources so they can be easily copy-pasted between projects. Be aware of this downside, when you add dependencies to your Content Block.
