Terminbuchung & Kontakt-Button – Delta Booking Button

Delta Booking Button macht aus deiner WordPress-Seite ein self-hosted Online-Terminbuchungs-System mit einem schwebenden Buchungs- und Kontakt-Button. Gebaut für lokale Dienstleister – Friseure, Coaches, Praxen, Kanzleien und Agenturen –, die Termine online annehmen wollen, ohne die Daten ihrer Kunden an einen externen Anbieter zu geben. Buchung, Erinnerungen und Kalender laufen komplett auf deinem Server: kein externer Buchungsdienst, kein CDN, kein IP-Leak. Appointment Booking

• Event Types — unlimited appointment types with custom duration, buffer time, working hours, and custom questions
• Booking Popup — clean calendar with date and time-slot selection, opened from the floating button
• Auto-Reminders — confirmation and 24h reminder email with an ICS calendar file attached, sent via WP-Cron
• Self-Service Reschedule — token-based link, no login required for your client
• External Calendar Sync (optional) — read busy times from an iCal/Google/Outlook feed to block double-bookings
• Timezone Support — UTC storage, visitor-local display, DST-safe

Floating Button & CTA

• Three Button Types — Single Button, Multi-Action FAB, Chat Widget
• 369 Icons — Social, UI, E-Commerce, Brands, Arrows, Navigation (local SVG sprite, no CDN)
• Smart Triggers — Time-based, Scroll Depth, Exit-Intent, Device, User State, URL Conditions
• Action Types — booking, WhatsApp, Telegram, phone, SMS, email, links and webhooks

Conversion Tracking

• Behavioral Tracking — Impressions, Clicks, Hover-Intent, Rage-Click Detection, Conversion Events
• Funnel Analytics — Impression > Hover > Click > Conversion with drop-off rates
• UTM Tracking — source/medium/campaign/content/term per click

Privacy & Self-Hosting (GDPR)

• Everything runs on your own WordPress install — no third-party booking provider
• All assets (CSS, JS, 369 SVG icons) are bundled locally — no CDN, no external requests
• IP anonymization on by default; right-to-deletion endpoint included
• Cookie-consent auto-detect: Borlabs Cookie, Cookiebot, Real Cookie Banner, Complianz — tracking starts only AFTER explicit consent
• Email runs through your own wp_mail() configuration — no external email API

Performance

• Conditional Loading — assets only on pages with active buttons
• GPU-accelerated animations
• Slim frontend: ~18 KB JS + ~8 KB CSS (gzipped), zero external requests
• Custom DB tables (no wp_options spam)

Security

• Nonce validation on all admin endpoints
• Rate limiting (60 events/min/session)
• Honeypot + time-check anti-spam
• IP anonymization by default

2.1.1

• Fixed: chat widget panels (mini chat, contact form, iframe) did not respond to mouse or touch input — fields and buttons inside the panel were unclickable. All widget variants are now fully interactive.
• Fixed: contact form fields inside the chat widget could overflow the panel edge on some themes (missing box-sizing).
• Fixed: the "sales button" wizard template referenced a non-existent icon, rendering an empty icon circle.
• Fixed: the email action on a single button produced a double "mailto:mailto:" link, so the mail client opened with an invalid address. Email buttons now open correctly.
• Fixed: the analytics "Export" link returned a 404 on sites using plain permalinks (default WordPress setting).
• Fixed: in the button builder, selecting a sub-button kept the previous tab highlighted while showing the action panel — tab highlight and panel content now stay in sync.
• Fixed: the bookings screen showed the number of buttons instead of bookings in its tab badge, and triggered PHP notices when WP_DEBUG was enabled.
• Fixed: the customer "reschedule appointment" page showed every date as unavailable on sites with plain permalinks — self-service rescheduling now works.
• Fixed: choosing "Book appointment" in the wizard silently saved a broken "open URL" action — the button did nothing when clicked. The wizard now saves the correct booking action.
• Fixed: the internal button name typed in the wizard was discarded on save.
• Fixed: on mobile, all floating buttons collapsed onto the exact same corner, covering each other (and footer links). Buttons now stack with proper spacing like on desktop.
• Answers to custom booking questions are now visible in the bookings list (they were stored but never shown).
• The wizard no longer suggests a Calendly URL for the built-in booking calendar.
• Fixed: already-booked time slots could still be offered in the slot list (booking them was then rejected with an error). Availability filtering now reliably removes conflicting slots.
• Admin design refresh — softer multi-layer shadows, larger corner radii, and harmonized form-control rounding for a more modern look (admin UI only; no frontend layout or structural changes).
• Updated plugin screenshots to reflect the refreshed admin interface.

2.1.0

• Frontend popups pixel-perfect implementation — Booking popup and WhatsApp mini-chat match design specs
• Booking popup: Navy gradient header, two-line subtitle, improved calendar cells with navy border selection state
• WhatsApp mini-chat: Green gradient header, proper avatar styling, WhatsApp-style bubble with timestamp
• Master FAB icon color fix — no more yellow override
• Click-only verification — popups only open on FAB click, never automatically
• WP-Admin full-screen mode for plugin pages
• Check button logic — blue checkmark triggers same submit path as green send button
