How to use dynamic title in frontmatter

Support
1

Hi! I found various questions and answers on the matter, however, none of them seems to work.

Here’s my scenario: a form with a /thankyou/formdata.md embedded in other page(s).

---
title: '{{ CONTACTFORM.SENT_MESSAGE_PAGE_TITLE }}'
cache_enable: false
process:
    twig: true
---

## {{ 'CONTACTFORM.SENT_MESSAGE_PAGE_TEXT'|t }}

Body gets translated, however title is not, regardless of the syntax used (when not throwing error).

Any advice?

Thanks!

@phmg701,

I found various questions and answers on the matter, however, none of them seems to work.

Before I repeat what others have done already…

  • Which questions and answers have you found?
  • For each: What doesn’t work, or doesn’t meet your needs?

I guess using multiple formdata.<lang>.md has already been suggested?

@pamtbaau you’re right, sorry!
Various combinations of {{ “STRING” }} with or without |t filter, quotes, double quotes. I didn’t find a working combination for the frontmatter, but I could be wrong on interpreting syntax!
Yes, <lang>.md could be a solution, yet title: wouldn’t be a string of languages.yaml which is my goal as form.md is language-agnostic and fully translatable (page has no title as it is a non published page, I then embed the form elsewhere, very powerful Grav feature).
Thanks!

@phmg701, Did some playing and it seems the following is working:

  • Fresh install of Grav 1.17.24
  • Updated /user/config/system.yaml:
    languages:
  supported: [en, de]

pages:
  frontmatter:
    process_twig: true     # Should the frontmatter be processed to replace Twig variables?
  • Created Contact form in two languages + single thankyou page:
    user/pages
├── 01.home
│   └── default.md
├── 02.typography
│   └── default.md
└── 03.contact
    ├── form.de.md
    ├── form.en.md
    └── thankyou
        └── formdata.md
    03.contact/form.en.md + 03.contact/form.de.md
    ---
title: Contact Form

form:
    name: contact

    fields:
        name:
          label: Name
          type: text

    buttons:
        submit:
          type: submit
          value: Submit

    process:
        message: Thank you for getting in touch!
        display: thankyou
---
    formdata.md
    ---
title: "{{ 'TITLE'|t }}"
process:
    twig: true
---

## {{ 'CONTENT'|t }}
  • Added translation to user/themes/quark/languages.yaml
    en:
  TITLE: Title-EN
  CONTENT: Content-EN

de:
  TITLE: Title-DE
  CONTENT: Content-DE
  • Browsed to localhost/en/contact, filled in the form and hit submit =>
    Page title is English version + content is English version
  • Browsed to localhost/de/contact, filled in the form and hit submit =>
    Page title is German version + content is German version

Hope this is what you were looking for… If not, I’ve had some fun anyway.

Thank you! Works flawlessly!
I also managed to put a failsafe in the Twig template in case page title is missing, just in case…
Thanks again!
