README
TYPO3 extension allowing to write your meta-tags in
Fluid. Syntax is a close as possible to the HTML
<meta> tag. Ships with one level of override.
Installation
Via composer
composer require undkonsorten/meta-tags
or from Github
Configuration
No configuration is needed, there‘s no TypoScript to include.
Usage
To use the view helper in your Fluid templates you have to import the namespace, e.g.:
<html xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers"
xmlns:m="http://typo3.org/ns/Undkonsorten/MetaTag/ViewHelpers"
data-namespace-typo3-fluid="true">
or
{namespace m=Undkonsorten\MetaTag\ViewHelpers}
Then you can use the meta view helper in any of the following forms:
<!--Tag style-->
<m:meta http-equiv="content-type" content="{settings.contentType}" />
<!--Inline style-->
{m:meta(property:'og:description',content:description)}
<!--You can omit content attribute and use tag content instead-->
<m:meta property="og:image"><f:uri.image image="{image}" width="800" height="600" absolute="1" /></m:meta>
<!--The same works for inline syntax-->
{author.fullName -> m:meta(name:'author')}
If the content is empty (i.e. only white-space characters) no meta tag is added. There‘s no need to wrap each of your meta tags in an if construct just to get rid of the empty ones.
Overriding
If for a requested meta tag there‘s a collision with an existing meta tag
(same property / name / http-equiv value) then the existing one will
be kept and the new one will be discarded. To change this behavior you can
set override="1". Then any existing meta tag of the same
type will be overridden.
That means you have a two-level hierarchy that works regardless
of processing order at run time. Just define your "global" meta tag
with values e.g. from pages record without override but set that flag
for your more specific ones, e.g. coming from extension show actions.
