| 2 | * WP 2FA - Setup Wizard Core |
| 3 | * |
| 4 | * A fully extensible, wp.hooks-driven wizard for configuring 2FA methods |
| 5 | * on a per-user basis. Methods register themselves via hooks so the wizard |
| 6 | * is decoupled from any specific 2FA provider. |
| 7 | * |
| 8 | * @package wp2fa |
| 9 | * @since 4.0.0 |
| 10 | * |
| 11 | * Hooks reference (all via wp.hooks): |
| 12 | * |
| 13 | * Filters: |
| 14 | * wp2fa_wizard_methods - Collect enabled methods for current user. |
| 15 | * Each method adds an object: { id, name, description, order } |
| 16 | * wp2fa_wizard_backup_methods - Collect enabled backup/secondary methods for current user. |
| 17 | * Each backup method adds: { id, name, description, order } |
| 18 | * wp2fa_wizard_step_title - Filter the title shown for a given step. |
| 19 | * wp2fa_wizard_can_proceed - Whether the "Continue" button should be enabled. |
| 20 | * wp2fa_wizard_modal_classes - Filter additional CSS classes on the modal container. |
| 21 | * |
| 22 | * Actions: |
| 23 | * wp2fa_wizard_opened - Fired when wizard modal opens. |
| 24 | * wp2fa_wizard_closed - Fired when wizard modal closes. |
| 25 | * wp2fa_wizard_method_selected - Fired when a method is selected (args: methodId). |
| 26 | * wp2fa_wizard_step_shown - Fired when a wizard step becomes visible (args: stepId). |
| 27 | * wp2fa_wizard_render_method - Render method-specific configuration UI (args: methodId, containerEl). |
| 28 | * wp2fa_wizard_render_backup_method - Render backup-method UI (args: methodId, containerEl, context). |
| 29 | * wp2fa_wizard_before_proceed - Fired before moving to next step (args: currentStepId, nextStepId). |
| 30 | * wp2fa_wizard_after_proceed - Fired after moving to next step (args: newStepId). |
| 31 | * wp2fa_wizard_before_back - Fired before going back a step. |
| 32 | * wp2fa_wizard_after_back - Fired after going back a step. |
| 33 | * wp2fa_wizard_validate_method - Fired when user submits verification for a method (args: methodId, containerEl). |
| 34 | * wp2fa_wizard_method_validated - Fired when a method has been validated successfully (args: methodId). |
| 35 | * The core listens for this and proceeds to backup methods or closes. |
| 36 | * wp2fa_wizard_init - Fired after the wizard core initializes. |
| 37 | * wp2fa_wizard_complete - Fired when the entire wizard flow is complete (no more steps). |
