Fix Drupal Element Type Errors

You will learn to fix drupal element type errors

The Problem

The drupal form element type 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

$element = ['#markup' => '<script>alert("xss")</script>']; // XSS vulnerability

No sanitization. XSS attack vector.

Right

$element = ['#markup' => Html::escape('<script>alert("xss")</script>')];

Output sanitized. Safe rendering.

Prevention

• Use #plain_text for simple text, #markup only with sanitized HTML
• Use Xss::filter for allowed HTML
