How to migrate latitude & longitude geodata into a unified geocode field

geofield_migration.yml

field_geofield:
  plugin: geofield_latlon
  source:
    - field_latitude
    - field_longitude

Issue:

Migrating geographic coordinate data from the geofield module into a unified geofield requires correct source field mapping.

Solution:

The code uses the geofield_latlon plugin to combine latitude and longitude fields in the specified order for proper geofield migration.

See the Drupal documentation for more info about the topic.

How to translate the Maxlength Countdown message label globally

A Drupal backend screenshot showing the "Count down message" field

Leave this field empty to allow for translation via Drupal interface translation.

Example configuration created by enabling Maxlength:

core.entity_form_display.node.article_not_translatable.default.yml

# ...
content:
  field_copyright:
    type: text_textarea
    weight: 3
    region: content
    settings:
      rows: 2
      placeholder: ''
    third_party_settings:
      allowed_formats:
        hide_help: '1'
        hide_guidelines: '1'
      maxlength:
        maxlength_js: null
        maxlength_js_label: 'Content limited to @limit characters, remaining: <strong>@remaining</strong>'
        maxlength_js_enforce: false
# ...

However, the module already contains fallback logic for this label in maxlength.module:

maxlength.module

$maxlength_js_label = !empty($thirdPartySettings['maxlength']['maxlength_js_label']) ? $thirdPartySettings['maxlength']['maxlength_js_label'] : t('Content limited to @limit characters, remaining: <strong>@remaining</strong>');
$maxlength_js = $thirdPartySettings['maxlength']['maxlength_js'];

Working configuration: empty the label

core.entity_form_display.node.article_translatable.default.yml

# ...
content:
  field_copyright:
    type: text_textarea
    weight: 3
    region: content
    settings:
      rows: 2
      placeholder: ''
    third_party_settings:
      allowed_formats:
        hide_help: '1'
        hide_guidelines: '1'
      maxlength:
        maxlength_js: null
        maxlength_js_label: ''
        maxlength_js_enforce: false
# ...

With the label empty, the module falls back to its internal t() string, which can then be translated normally via the interface translation system.
