原文外掛簡介

LW Simple Forms is a versatile WordPress form plugin that allows you to create customizable forms. It supports the Japanese-style workflow of a complete form submission process:

Input screen – Users enter their information
Confirmation screen – Users review their input before submitting
Completion screen – Thank you message after successful submission

The plugin also supports a simpler one-step submission process when confirmation is not needed.
Development Concept

HTML-First Approach: This plugin is designed to faithfully reproduce your designed HTML forms, confirmation screens, and error screens without forcing you to adapt to plugin limitations. The forms conform to your design, not the other way around.

Built for Web Professionals: LW Simple Forms does not provide CSS or HTML templates for the frontend. It’s specifically created for web designers and developers who already have designed their form screens and need a way to implement the functionality. (HTML/CSS samples are available for reference.)

Minimalist Philosophy: This plugin intentionally maintains a minimalist approach, focusing on core functionality rather than excessive features. We prioritize site speed and minimal data usage to keep your websites running efficiently.

Key Features

Complete Form Workflow: Create forms with input screen, error screen, confirmation screen, and completion screen
Flexible Design: Customize each screen with your own HTML
Form Validation: Server-side and client-side validation for each input field (required fields, email format, phone number validation)
Email Notifications: Send confirmation emails to both administrators and users
Security Features: CSRF protection, data sanitization, input validation, and secure data handling
Multiple Field Types: Support for text fields, text areas, checkboxes, radio buttons, select menus, and multi-select menus
Shortcode Support: Easy integration into WordPress pages via shortcodes
Custom HTML: Design your forms with complete HTML freedom
Multi-Form Support: Create and manage multiple forms on a single site
Database Storage: Form data is temporarily stored in the database rather than in sessions or cookies, allowing for unlimited submission data
JavaScript/No-JavaScript Support: Forms work properly even in environments where JavaScript is disabled (e.g., screen readers)
Field Validation: Extensive validation system with customizable error messages
Security Measures: Protection against common vulnerabilities including CSRF attacks and header injection

Usage Guide

Design and create the HTML for input screen, confirmation screen, and completion screen
Register each screen as a WordPress page
Create a new form from “Forms” in the WordPress admin panel
Configure each section. You can configure the following:

HTML for each screen (input, confirmation, completion)
URL for each screen
Administrator email settings
User email settings
Validation settings (required fields, email format, phone number validation)

Use the “Parse HTML” button to automatically extract form fields from your input screen HTML
Add the appropriate shortcodes to your pages
Test the form operation before going live

Note: This plugin is designed to give you maximum freedom in writing form HTML, so you need to write the HTML for your form pages yourself. The plugin does not provide CSS or images for form display. HTML samples are available for reference.

Data Storage and Security

Form submissions are temporarily stored in the WordPress database (prefix_lwsf_form_data table)
Data is automatically cleaned up after 1 hour
All user inputs are sanitized before processing
CSRF protection is implemented on all form submissions
Email headers are validated to prevent header injection

Why This Plugin Was Created
This plugin was created because MW WP Form, which had been used for client work for many years, ended development. There was a need for a form plugin with confirmation screens that operated cleanly. The plugin was created primarily for web development work, and we thought many web development companies might have similar needs.
Future Implementation Plans

The ability to change validation error messages
PHP-based validation hooks that operate before and after form submission
Additional validation types (URL, numeric values, custom regex patterns)
Hooks to trigger at important timings such as just before and just after email sending.
File upload handling
reCAPTCHA

Privacy Policy
This plugin stores form submission data in the WordPress database (prefix_lwsf_form_data table) for the purpose of displaying confirmation and completion screens. Data is automatically deleted after 1 hour.
When enabled, user email addresses may be used to send confirmation emails to form submitters. The plugin does not share any collected data with external services.
