Translate ViewHelper <f:translate>

Translate a key from locallang. The files are loaded from the folder Resources/Private/Language/.

Examples

Translate key

<f:translate key="key1" />
Copied!

Value of key key1 in the current website language. Alternatively id can be used instead of key:

<f:translate id="key1" />
Copied!

This will output the same as above. If both id and key are set, id will take precedence.

Keep HTML tags

<f:format.raw><f:translate key="htmlKey" /></f:format.raw>
Copied!

Value of key htmlKey in the current website language, no htmlspecialchars() applied.

Translate key from custom locallang file

<f:translate key="key1" extensionName="MyExt"/>
Copied!

or

<f:translate key="LLL:EXT:myext/Resources/Private/Language/locallang.xlf:key1" />
Copied!

Value of key key1 in the current website language.

Inline notation with arguments and default value

{f:translate(key: 'someKey', arguments: {0: 'dog', 1: 'fox'}, default: 'default value')}
Copied!

Value of key someKey in the current website language with the given arguments (dog and fox) assigned for the specified %s conversions, using PHP sprintf() notation in the language file:

<trans-unit id="someKey" resname="someKey">
    <source>Some text about a %s and a %s.</source>
</trans-unit>
Copied!

The output will be Some text about a dog and a fox.

If the key someKey is not found in the language file, the output is default value.

As in PHP's sprintf() you can order placeholders (Second %2$s, first %1$s) or use specific types like A padded number: %'.09d, returning 000000123 for a number passed as 123. See the sprintf PHP Documentation for more information on possible formatting.

Inline notation with extension name

{f:translate(key: 'someKey', extensionName: 'SomeExtensionName')}
Copied!

Value of key someKey in the current website language. The locallang file of extension "some_extension_name" will be used.
