Easy WhatsApp

A simple, secure, and lightweight WordPress plugin that adds a WhatsApp number meta field to selected post types and displays a modern floating WhatsApp button on the frontend.

Features

• Custom Meta Field: Securely add a WhatsApp number to any supported post type.
• Floating Button: Automatically displays a visually appealing floating WhatsApp button on the bottom-right corner of posts/pages with a configured number.
• Smart Device Routing:
  • Mobile users are directed to the native WhatsApp app.
  • Desktop users are routed directly to WhatsApp Web.
• Configurable: Choose exactly which post types (Posts, Pages, Custom Post Types) should have the WhatsApp field enabled via a simple settings page.
• Secure: Strict validation and sanitization ensure only valid phone numbers are saved to the database.

Installation

1. Upload the easy-whatsapp folder to your /wp-content/plugins/ directory.
2. Activate the plugin through the Plugins screen in WordPress.
3. Go to Easy WhatsApp > Settings to select the post types where the field should be available.

Usage

1. Edit a post within your selected post types (e.g., a standard Post).
2. Locate the WhatsApp Number meta box on the side panel.
3. Enter the target WhatsApp number using the international format with the country code (e.g., +12025550123).
4. Update or Publish the post.
5. Visit the post on the frontend to see the floating WhatsApp button in action!

Developer APIs

Developers can use the built-in helper function to retrieve the WhatsApp number programmatically within themes or other plugins:

// Get the WhatsApp number for the current post
$number = easy_whatsapp_get_number();

// Get the WhatsApp number for a specific post ID
$number = easy_whatsapp_get_number( 123 );

You can also filter the allowed post types via code:

add_filter( 'easy_whatsapp_post_types', function( $post_types ) {
    $post_types[] = 'my_custom_post_type';
    return $post_types;
} );
