DEPRECATION WARNING

This documentation is not using the current rendering mechanism and will be deleted by December 31st, 2020. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.

# Changing & editing templates¶

EXT:news is using fluid as template engine. If you are used to fluid already, you might skip this section.

This documentation won’t bring you all information about fluid but only the most important things you need for using it. You can get more information in books like the one of Jochen Rau und Sebastian Kurfürst or online, e.g. at http://wiki.typo3.org/Fluid or many other sites.

## Changing paths of the template¶

You should never edit the original templates of an extension as those changes will vanish if you upgrade the extension. As any extbase based extension, you can find the templates in the directory Resources/Private/.

If you want to change a template, copy the desired files to the directory where you store the templates. This can be a directory in fileadmin or a custom extension. Multiple fallbacks can be defined which makes it far easier to customize the templates.

plugin.tx_news {
view {
templateRootPaths >
templateRootPaths {
0 = EXT:news/Resources/Private/Templates/
}
partialRootPaths >
partialRootPaths {
0 = EXT:news/Resources/Private/Partials/
}
layoutRootPaths >
layoutRootPaths {
0 = EXT:news/Resources/Private/Layouts/
}
}
}


### Change the templates using TypoScript constants¶

You can use the following TypoScript in the constants to change the paths

plugin.tx_news {
view {
}
}


### Change path of the pagination widget¶

The path of the pagination widget can be changed by using a configuration like below.

plugin.tx_news {
view {
widget.GeorgRinger\News\ViewHelpers\Widget\PaginateViewHelper.templateRootPath = {\$plugin.tx_news.view.templateRootPath}
}
}


## Layouts, Templates & Partials¶

If using fluid, the templates are structured by using Layouts, Templates and Partials.

### Layouts¶

Layouts are used to structure the output of a plugin. A simple example is to wrap every output with the same <div> element. Therefore it is not needed to repeat this code and write it only once.

A layout can look this:

<div class="news">
<f:render section="content" />
</div>


This means that the output of the section content will be rendered inside a div with the class news.

### Templates¶

Every action (like the list view, the detail view, date menu or a category listing) needs its own template which can be found at Templates/<Model>/<ActionName>.html.

If Layouts are used, it is required to define the name of the Layout (which is identical to the file name of the Layout file).

<f:layout name="General" />

<f:section name="content">
This will be rendered
</f:section>


Note

It is optional to use Layouts. If those are not used, the complete content of the Template is shown.

### Partials¶

Partials are used within templates to be able to reuse code snippets. If you open the template News/List.html you will see the partial:

<f:render partial="List/Item" arguments="{newsItem: newsItem, settings:settings, className:className, view:'list'}"/>


This will embed the output of the partial which is located at Partials/List/Item.html (as stated in the attribute partial ). All arguments which are used in the attribute arguments are available in the partial itself.

You can create your own partials and name them as you like

### Sections¶

Sections are very similar to partials. The difference is that sections are defined in the same file as the template.

### ViewHelpers¶

Ever fluid viewhelper starts with <f: . and you can always check out the code at typo3/sysext/fluid/Classes/ViewHelpers/. As an example the viewhelper <f:link.page can be found at typo3/sysext/fluid/Classes/ViewHelpers/Link/PageViewHelper.php.

Any other viewhelpers from other extensions can be used by using a namespace declaration like

{namespace n=GeorgRinger\News\ViewHelpers}


Then viewHelpers of EXT:news (which can be found in news/Classes/ViewHelpers) can be used with the prefix n: .
