Devify WhatsApp Chat

A highly configurable WhatsApp live-chat widget for WordPress: a floating launcher with a polished preview card (think of the familiar "chat bubble" pattern), a one-tap link straight into a WhatsApp conversation, and a smart pre-filled message that adapts to the page the visitor is on. Works on any theme, with no page builder required.

Features

• Floating launcher + preview card with brand header, avatar, welcome message, and call-to-action button
• Smart pre-filled messages with dynamic tokens: {page_title}, {page_link}, {site_name}, {site_url}
• Fully themeable from a settings screen — accent colour, text colour, fonts, radius, launcher size, position, offsets, and z-index
• Display rules — device visibility (all / desktop / mobile), optional display delay, hide for logged-in users
• Shortcode for inline "message us" links anywhere in content
• Customizer integration for live, visual previewing
• Developer-friendly — a dozen filters and a theme-overridable template
• Privacy-respecting — no third-party scripts; the widget is a styled link to wa.me
• Translation-ready, with uninstall.php cleanup and a WordPress.org-format readme.txt

Install

1. Copy devify-whatsapp-chat into wp-content/plugins/
2. Activate it under Plugins
3. Configure at Settings → WhatsApp Chat, or define the number in wp-config.php:

define( 'DWC_WHATSAPP_NUMBER', '+15551234567' );

Shortcode

[whatsapp_chat]
[whatsapp_chat label="Message us" message="Hello from {page_title}"]

Architecture

devify-whatsapp-chat.php          Bootstrap: constants, optional wp-config number, boot
includes/
  class-dwc-plugin.php            Singleton controller; shortcodes; activation
  class-dwc-settings.php          Settings storage, defaults, sanitization
  class-dwc-config.php            Builds the runtime widget config (colours, copy, URL)
  class-dwc-frontend.php          Enqueues assets, decides visibility, renders the widget
  class-dwc-admin.php             Settings page wiring
  class-dwc-customizer.php        Live Customizer controls
  functions.php                   Helpers: phone sanitize, wa.me URL, message tokens
  views/settings-page.php         Admin settings UI
templates/
  widget.php                      Front-end markup (theme-overridable)
assets/                           Widget + admin CSS and JS
uninstall.php                     Removes plugin options on delete

Each concern lives in its own class, wired through a singleton controller — so the URL building, the settings, the rendering, and the admin UI can each be read and changed independently.

Template override

Drop a copy in your active theme to fully control the markup:

wp-content/themes/your-theme/devify-whatsapp-chat/widget.php

…or filter dwc_whatsapp_template_path.

Hooks

Requirements

WordPress 6.0+, PHP 7.4+, and a WhatsApp-enabled phone number. No external accounts or API keys — the widget links directly to WhatsApp's standard wa.me URLs.
