Frontmatter global setting for Default page

i searched the entire help center
I could not find what i was looking for, basically i need to know where i would set the following frontmatter "global" for each new Default page created:

access:
site.login: true
site.admin: true

I don't want any page accessible without login, for now I am manually adding the 3 lines to each new page i create but i want those 3 lines included from the start already, i could not find the config file to set this default behaviour to..

Please help,
thx mik

@mikulabc If you are using the Admin panel to create pages, the following might be a solution. If you create pages manually using an editor I would not know of any Grav solution.

Grav allows you to extend the blueprints used by Admin to generate pages. Have a look at the docs on Page Blueprints.

In the following example, a new section 'Access' with two new fields will be added to the bottom of tab 'Advanced'. The defaults are being set to 'true'. Every time a page is created using Admin panel, the two fields are added to the frontmatter of the page.

• Create file '/user/blueprints/pages/default.yaml

• Add the following to the page:

  YAMLCopy

  title: Access
  '@extends':
    type: default
    context: blueprints://pages
  
  form:
  fields:
    tabs:
      type: tabs
      active: 1
  
      fields:
        advanced:
          fields:
            access:
              type: section
              title: Access
              underline: true
              fields:
                header.access.site.login:
                  type: toggle
                  label: Site login
                  highlight: 1
                  default: 1
                  options:
                      1: PLUGIN_ADMIN.ENABLED
                      0: PLUGIN_ADMIN.DISABLED
                  validate:
                      type: bool
                header.access.site.admin:
                  type: toggle
                  label: Site admin
                  highlight: 1
                  default: 1
                  options:
                      1: PLUGIN_ADMIN.ENABLED
                      0: PLUGIN_ADMIN.DISABLED
                  validate:
                      type: bool
  

  Off course, you can place the section/fields somewhere else e.g another tab.

Hope this helps...

For grav v1.7.23 there is already a form field for page access.

We can override this in /user/blueprints/pages/default.yaml with

'@extends':
  type: default
  context: blueprints://pages

form:
  fields:
    tabs:
      fields:
        security:
          fields:
            _site:
              fields:
                header.access:
                  default:
                    site.login: true
