Incorporating a captcha into your Contact Form 7 can aid in deterring undesired spam submissions and guarantee the authenticity of the messages received through your form. This article will lead you through the steps of implementing a captcha in Contact Form 7, while also sharing my personal perspectives and anecdotes.
What is Contact Form 7?
Contact Form 7 is a popular WordPress plugin that allows website owners to easily create and manage contact forms. It is highly customizable and offers various features to enhance the functionality of your forms.
Why Add a Captcha?
Spam bots are automated programs that can fill out web forms and submit spam messages. By adding a captcha, you can verify that the form submissions are made by real human users and not by these malicious bots.
Step 1: Install and Activate the reCAPTCHA Plugin
To add a captcha to Contact Form 7, we will be using the Google reCAPTCHA plugin. Start by installing and activating the plugin on your WordPress website. You can easily find and install it from the WordPress Plugin Directory.
Step 2: Create reCAPTCHA API Keys
After activating the reCAPTCHA plugin, you need to generate the API keys necessary for the captcha to work. Head over to the reCAPTCHA settings page and sign in with your Google account. Follow the instructions provided to create a new site and obtain the API keys.
Step 3: Configure Contact Form 7
Once you have the API keys, go to the Contact Form 7 settings in your WordPress dashboard. Edit the contact form you want to add the captcha to or create a new one.
In the form editor, you will find a new section titled “reCAPTCHA” under the “Form” tab. Enable the “Use reCAPTCHA” option and enter the site key and secret key that you obtained in the previous step.
Step 4: Add the Captcha Field to Your Form
To actually display the captcha field in your form, you need to add the following shortcode to the form editor:
[recaptcha]
Place this shortcode in the desired location within your form. You can also customize the appearance of the captcha field by adding attributes to the shortcode.
Step 5: Test Your Captcha
Before you make the form live, it’s important to test the captcha to ensure it is working correctly. Open the form in a new browser tab and submit it. The captcha should validate that you are a human user before allowing the form to be successfully submitted.
