Fix Drupal Block Cache Context Errors

You will learn to fix drupal block cache context errors

The Problem

The drupal block cache context pattern is frequently misapplied in smart contract and dapp development, leading to vulnerabilities, gas inefficiencies, or logic errors. This guide shows the correct implementation and common pitfalls to avoid.

Quick Fix

Wrong

public function build() { return ['#markup' => \Drupal::currentUser()->getDisplayName()]; }

No cache context. Shows wrong username to other users.

Right

public function getCacheContexts() { return ['user']; }

Cached per user. Each user sees their own name.

Prevention

• Add user context for user-specific content
• Add url context for path-specific content
