Hello,
I wish create some text with variables like :
TWIG
// config/annonces.yaml
region: "My region"
// config/news.yaml
presentation: My text blablabla <em>lbablaba {{ config.annonces.region }}</em> blabla ...
Is it possible ? Thx

See the docs:
You are also not limited to the
user/config/system.yamlor theuser/config/site.yamlfiles as described above. You can create any arbitrary.yamlconfiguration file in theuser/configfolder you wish and it will get picked up by Grav automatically.
I do not believe there's a way to reference other YAML files from within YAML. There are only node anchors. The YAML parser certainly won't parse the Twig. But I suppose if you inject the Twig early enough in the lifecycle, it will end up being processed when the page is.
I found the following in the Twig docs:
TWIG
{{ include(template_from_string("Hello {{ name }}")) }}
It seems this is what you are after, but I couldn't get it to work...
Prerequisite:
The
template_from_stringfunction is not available by default. You must add theTwig_Extension_StringLoaderextension explicitly when creating your Twig environment
@nicolasG Did some more research and managed to get the suggestion I made above working...
I'm using the Quark theme for convenience, but an inherited theme should be used for production.
These are the steps I took:
- Created file '/user/config/annonces.yaml' with content:
TXT
region: "My region" - Created file 'user/config/news.yaml' with content:
TWIG
presentation: My text blablabla <em>lbablaba {{ config.annonces.region }}</em> blabla ... -
In '/user/themes/quark/quark.php', I replaced the following lines:
TXTpublic function onThemeInitialized() { }with:
PHPpublic function onThemeInitialized() { // Don't proceed if we are in the admin plugin if ($this->isAdmin()) { return; } // Enable the main event we are interested in $this->enable([ 'onTwigExtensions' => ['onTwigExtensions', 0], ]); } public function onTwigExtensions() { $this->grav['twig']->twig->addExtension(new \Twig_Extension_StringLoader()); } - In '/user/themes/quark/templates/default.html.twig', I added the following line to block 'content':
TWIG
<h1>{{ include(template_from_string(config.news.presentation)) }}</h1> - Fired up the browser which shows:
My text blablabla lbablaba My region blabla ...

I didn't know where to put "Twig_Extension_StringLoader", your answer provides the solution, perfect, thank you very much!
Now, it opens a debate on the solution to be adopted... Let me explain:
Either this solution, or create a twig function that makes a simple "str_replace" of keywords containing in the text as %%city%%%% then in my html view, just do {{ replaceAndShowFunction(config.news.presentation) }}, what do you think?
Which solution would you prefer?
It depends on your decisive selection criteria of the solution. Only then can be decided which solution fits best.
I don't know yours, but I could think of criteria like:
- ease of implementation
- ease of maintenance
- flexibility/extensibility
- performance
