Add JetFormBuilder form integration

[davidperezgar]

Summary

Adds native FormsCRM integration for JetFormBuilder, enabling form submissions to be automatically sent to connected CRM/ERP systems.

Key Changes

• New form integration class (FORMSCRM_JetFormBuilder) that:

  • Registers a meta box on JetFormBuilder form editor for per-form CRM settings
  • Supports dynamic CRM credential fields (URL, username, password, API key, etc.) based on selected CRM type
  • Provides field mapping UI to connect JetFormBuilder form fields to CRM module fields
  • Hooks into jet_fb_on_success action to process form submissions and send data to the CRM
  • Handles both JFB 2.x (two-arg) and 3.x (single-arg) action signatures for compatibility

• Field extraction from JetFormBuilder's Gutenberg block structure:

  • Recursively parses form post content to discover all jet-forms/* field blocks
  • Supports both name and fieldName block attributes for field identification

• Dynamic value substitution using {id:field_name} shortcode syntax in field mappings

• Error handling that logs CRM submission failures to the error log without blocking form submissions

• Conditional loading in loader.php — integration only loads when JetFormBuilder plugin is active

Implementation Details

• Follows FormsCRM's standard CRM integration pattern: per-form settings stored as post meta, field mapping via fc_crm_field-* keys
• Reuses existing CRM library infrastructure (formscrm_get_api_class(), formscrm_render_connection_status(), etc.)
• Supports expert mode to show all CRM fields
• Enqueues admin stylesheet on form edit screen for consistent UI with other form integrations
• Properly sanitizes and validates all user input; uses nonces for settings save
