Changing & editing templates¶
EXT:news is using Fluid as templating 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 the TYPO3 Documentation TYPO3 Explained: Fluid or many third party sites, videos and books.
Use a site package extension¶
It is recommended to always store overwritten templates in a custom TYPO3 extension. Usually this is done in a special extension called the site package.
If you do not have a site package yet you can create one manually following this Official Tutorial: Site Package.
There is also a site package generator available (Provided by Benjamin Kott).
Create a directory called
EXT:mysitepackage/Resources/Private/Extensions/News
for example and
create 3 directories therein called Templates
, Partials
and
Layouts
. In these directories you can store your version of the Fluid
templates that you need to override.
As any Extbase based extension, you can find the original templates of the
extension news in the directory EXT:news/Resources/Private/
.
If you want to change a template, copy the desired files to the directory in your site package. If the template is in a sub folder you have to preserve the folder structure.
For example the template:
EXT:news/Resources/Private/Templates/News/Detail.html
would have to be copied to
EXT:mysitepackage/Resources/Private/Extensions/News/Templates/News/Detail.html
Since your site package extends the extension news you should require news in
your composer.json
:
{
"require": {
"georgringer/news": "^9.0"
}
}
And / or ext_emconf.php
:
$EM_CONF[$_EXTKEY] = [
// ...
'constraints' => [
'depends' => [
'news' => '9.0.0-9.99.99',
],
// ...
],
];
Note
It is not recommended anymore to store Fluid templates in the
fileadmin
directory.
Changing paths of the template¶
Warning
You should never edit the original templates of an extension as those changes will vanish if you upgrade the extension.
In the most common case, where you want to override the standard news template with your own templates you can use the TypoScript constants to set the paths:
plugin.tx_news {
view {
templateRootPath = EXT:mysitepackage/Resources/Private/Extensions/News/Templates/
partialRootPath = EXT:mysitepackage/Resources/Private/Extensions/News/Partials/
layoutRootPath = EXT:mysitepackage/Resources/Private/Extensions/News/Layouts/
}
}
If needed, multiple fallbacks can be defined with TypoScript setup:
plugin.tx_news {
view {
templateRootPaths >
templateRootPaths {
0 = EXT:news/Resources/Private/Templates/
10 = EXT:mynewsextender/Resources/Private/Templates/
15 = EXT:myothernewsextender/Resources/Private/Templates/
20 = {$plugin.tx_news.view.templateRootPath}
}
partialRootPaths >
partialRootPaths {
0 = EXT:news/Resources/Private/Partials/
10 = EXT:mynewsextender/Resources/Private/Partials/
15 = EXT:myothernewsextender/Resources/Private/Partials/
20 = {$plugin.tx_news.view.partialRootPath}
}
layoutRootPaths >
layoutRootPaths {
0 = EXT:news/Resources/Private/Layouts/
10 = EXT:mynewsextender/Resources/Private/Layouts/
15 = EXT:myothernewsextender/Resources/Private/Layouts/
20 = {$plugin.tx_news.view.layoutRootPath}
}
}
}
It is recommended to always include the path from the TypoScript constants last (with the highest numeral) so that the site package can still override the templates.
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 = EXT:mysitepackage/Resources/Private/Extensions/News/Templates/
}
}
}
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="myFancyNews">
<f:render section="content" />
</div>
This means that the output of the section content
will be rendered
inside a div with the class myFancyNews
.
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
EXT:news/Resources/Private/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 without file extension).
<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 Templates/News/List.html
you will see the
render ViewHelper:
<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
(attribute partial, line 2). All
arguments which are used in the attribute arguments (line 3ff)
are available in the partial itself.
You can override existing partials or create your own 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¶
Every Fluid ViewHelper starts with <f:
. The view helpers supplied by
TYPO3 are documented in the ViewHelper Reference.
Any other ViewHelpers from other extensions can be used by using a namespace declaration like
<html xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers"
xmlns:n="http://typo3.org/ns/GeorgRinger/News/ViewHelpers"
xmlns:x="http://typo3.org/ns/Vendor/SomeExtension/ViewHelper"
data-namespace-typo3-fluid="true">
...
</html>
Then ViewHelpers of EXT:news can be used with prefix n:
. You can find
the available ViewHelpers in the chapter
ViewHelper reference.
