Lightweight Contact Form Plugin

This is the absolute lightest contact form for WordPress. This plugin is designed for the fastest pagespeed. So, there is no CSS stylesheet, no extra files, and no overhead. And no spam. It uses Google reCAPTCHA v3 so as not to annoy your users with any extra step, while keeping your contact form spam-free.

If all you need is a simple contact form to take messages from site visitors, and fast page speed is your priority, this minimal plugin is for you.

Although this form is lightweight and simple, it blocks SPAM, and has both client-side and server-side validation. This is a solid and dependable contact form.

NOTE: To make use of the extra spam protection from Google reCAPTCHA v3, you must get your reCAPTCHA v3 API keys from Google. This is a free and easy step, and is strongly recommended.

Features

• Emails are sent to the admin email which is set in your WordPress General Settings.
• Add the contact form to any page with a shortcode.
• Both JavaScript client-side and PHP server-side validation.
• It’s just one file. No extra CSS or JavaScript files. This is for the most lightweight footprint.

You must add any CSS styling yourself. This is easy and is explained in the installation guide.

(In addition, if you need extra fields or different forms for different pages, see the Advanced: Add Custom Form Fields section.)

Install and Activate

1. Install and activate the plugin in your WordPress dashboard by going to Plugins –> Add New.
2. Search for “Lightweight Contact Form” to find the plugin.
3. When you see “Lightweight Contact Form,” click “Install Now” to install the plugin.
4. Click “Activate” to activate the plugin.

Quick Setup

Add the contact form to any page with this shortcode:

[lcf_contact_form] 

Optionally, add these CSS styles to align the form fields.

This step is strongly recommended: To stop SPAM on your contact form, get your free Google reCAPTCHA keys. Then, enter those keys in your WordPress admin settings by going to Settings > Discussion. On the Discussion Settings page, scroll all the way down to “Lightweight Contact Form” where you’ll find the place to enter your reCAPTCHA v3 Site key and reCAPTCHA v3 Secret key.

That is all. Now you have a lightweight, working contact form on your WordPress site. When someone fills out and submits your contact form, it will be sent to the admin email which is set in your WordPress General Settings.

To try the contact form, visit that page on your site.

(If you need extra fields or different forms for different pages, see the Advanced: Add Custom Form Fields section.)
