Contact Form 7 Validate Email

Description

The Contact Form 7 Validate Email plugin enhances the functionality of Contact Form 7 by providing email validation. It checks if the entered email address exists in the WordPress user database before allowing form submission. If the email does not exist, it displays a custom error message to the user.

Features

• Validates email addresses in Contact Form 7 submissions.
• Checks email existence against the WordPress user database.
• Displays custom error messages for invalid emails.
• Enhances user experience by preventing submissions with non-existent emails.

2. Log in to your WordPress admin dashboard.
3. Navigate to the "Plugins" section.
4. Click "Add New" and then "Upload Plugin."
5. Choose the downloaded ZIP file and click "Install Now."

Usage

1. Make sure you have Contact Form 7 installed and configured on your WordPress site.
2. Identify the form you want to apply email validation to and take note of its form ID.
3. Open your theme's functions.php file or a custom plugin file.
4. Locate the add_filter hook for wpcf7_validate and modify the form ID condition in the gravixar_email_exists function to match your target form ID.

6. Save the changes.

Example:

// Modify this condition to match your target form ID
