The Problem

The drupal view query filter 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

$query->addWhere('AND', 'node_field_data.status', 1, '=');

Correct but doesn't expose filter to UI.

Right

$query->addWhere('AND', 'node_field_data.status', 1, '='); $handler->options['expose'] = TRUE;

Filter applied and exposed to users.

Prevention

• Use exposed filters for user-configurable filtering
• Set proper filter operators
