Drupal Text Formats

Standardizing HTML formats involves defining a single allowed HTML tag set, configuring matching CKEditor button sets to align with those tags, and applying consistent access controls so authors cannot switch between conflicting formats. This ensures secure, predictable authoring across your Drupal site.

Map each CKEditor button to its corresponding allowed HTML tag, then remove insecure options from both the editor configuration and the text format's tag allowlist. This prevents authors from generating HTML that the format will strip or reject, reducing authoring confusion.

Yes. Implement mirrored access controls by assigning each text format to specific roles or fields, preventing format switching while maintaining separate configurations for different content types if needed. This enforces a predictable editing experience.

Use the provided validation script to check that allowed HTML tags match editor button sets and that access rules are correctly applied. This catches misalignments that could cause data loss or security issues before they reach production.

Remove dangerous HTML tags and attributes (like script, iframe, onclick) from both the allowed tags list and CKEditor toolbar to prevent XSS attacks. Restrict format access by role to ensure only trusted users can create content in less-filtered formats.
