• Open Login and Registration form in popup (with ability to tune Login and Registration popups settings), Drupal 8 version

Basic usage

Flag anonymous module helps you to show existing "flagging" ability to anonymous users and motivate them to login or register in a simple way (on the same page using popup).

Requirements

• Flag

Installation

• Install the module to:
  • Drupal 7: sites/all/modules/contrib or sites/all/modules
  • Drupal 8: modules/contrib or modules
    or with Composer: $ composer require 'drupal/flag_anon:^1.0'
• Enable Flag anonymous module

Configuration (Drupal 8)

• Go to a Flags list page /admin/structure/flags
• Click "Edit" link on Flag which you'd like to configure
  • Or click "Add flag" button if you'd like to add a new Flag
• Scroll down flag edit page to "Anonymous settings" section
• Check "Show this flag to anonymous users even if they don't have permission to use it." checkbox to enable module functionality.
  • IMPORTANT NOTE: Anonymous users shouldn't have Flag/Unflag permission for currently edited flag (shouldn't be able to use this flag). If anonymous users have Flag/Unflag permission remove it using /admin/people/permissions#module-flag page, otherwise module functionality will be blocked.
• Choose "Label display" option:
  • "Keep original flag label (show Message on click)" - in this case original flag label will be displayed. On click by it: Popin with "Login or Register to use this flag" message will be displayed.
    • Set "Dialog message title" - it's a title of Popin with "Login or Register to use this flag" message. Leave blank to have empty Popin title.
  • "Show Message instead of flag label" - in this case flag label will be replaced with "Login or Register to use this flag" message.
• Set "Message" - it's a "Login or Register to use this flag" message. You can use: @login - Login link, @register - Registration link placeholders there.
• Set "Login link label" - a label for Login link placeholder.
• Set "Register link label" - a label for Registration link placeholder.
• Check "Show Login and Registration form in popup." checkbox if you'd like to show Login and Registration forms in Popup on click by "Login" or "Register" links
  • "Login popup settings" - Login popup settings for data-dialog-options attribute. Valid JSON should be used like: {"width": "auto"}
  • "Register popup settings" - Registration popup settings for data-dialog-options attribute. Valid JSON should be used like: {"width": "auto"}
• Fill or change other needed fields and click "Save Flag" button.

For developers

To add custom placeholders into configurable "Login or Register to use this flag" message implement hook_flag_anon_message_placeholders_alter() and add additional placeholders there (see more details in flag_anon.api.php file).
