Description

EMB Buchungskalender & Reservierungen is a lightweight booking and availability calendar for WordPress websites.

It can be used for vacation rentals, rooms, equipment, parking spaces, shared facilities or other simple resources that need request-based day or date-range booking management.

The plugin provides:

Availability calendar with available, reserved and booked days.
Booking request form with configurable start and end date labels for day-based reservations.
Admin management for manual bookings and incoming requests.
Email notification for new requests, confirmations, rejections and cancellations.
Customizable resource names.
Customizable frontend labels and form texts.
Customizable colors for availability, reservation, booking and selected dates.
Customizable guest email subjects and message texts with placeholders.
Built-in email test tool for checking WordPress wp_mail() handoff.
Optional setup for multiple resources including a combined booking option.
Shortcode-based output without external tracking, external scripts or public credit links.

The plugin stores booking data locally in the WordPress database. It does not send data to external services. Email delivery uses the WordPress wp_mail() function and depends on the website’s mail configuration. A built-in email test tool can check whether WordPress can hand off a message to the server, but successful handoff does not guarantee inbox delivery by the recipient provider. The settings page also shows the last email test result as a small local diagnostic log.

Installation

Upload the plugin folder to /wp-content/plugins/ or install the ZIP file through the WordPress plugin screen.
Activate the plugin through the Plugins screen in WordPress.
Open the admin menu item “Buchungskalender” and review the settings.
Add the shortcode [embbres_buchungskalender] to the page where the calendar should appear.

Optional shortcodes:

[embbres_buchungskalender resource="objekt-1"]
[embbres_buchungskalender objekt="objekt-2"]
[embbres_buchungskalender resource="both"]

FAQ

Does the plugin send emails through an external provider?: No. The plugin uses the WordPress wp_mail() function. Delivery depends on the website’s normal WordPress mail setup and hosting environment. The settings page includes a dedicated test email and deliverability box; it checks the WordPress/server handoff and shows the last test result, but cannot guarantee final delivery to Gmail, Yahoo, Outlook, T-Online or other providers.
Can I use it for something other than apartments?: Yes. Resource names and frontend labels can be customized in the plugin settings, for example for rooms, equipment, parking spaces, shared facilities, rentals or vacation apartments. The free version is designed for day-based or date-range booking requests. Appointment booking with times or predefined time slots is not included in this version.
Can I customize the colors?: Yes. The plugin settings include color fields for available, reserved, booked, selected and past dates as well as background, border and text colors.
Can I customize the email texts?: Yes. The plugin settings include editable email subjects and body texts for new requests, booking confirmations, rejections and cancellations. Available placeholders include {gastname}, {vorname}, {nachname}, {ressource}, {objekt}, {ressource_label}, {objekt_label}, {wohnung}, {anreise}, {abreise}, {zeitraum}, {telefon}, {nachricht}, {seitenname} and {website}.
Are guest names shown publicly in the calendar?: No. Public calendar data only exposes availability status and date ranges. Guest details are only visible to administrators in the WordPress admin area.
Does it support appointment times or time slots?: Not in this free version. The plugin currently manages availability by date or date range. Appointment booking with times, durations, buffers, opening hours or predefined time slots is planned as a possible future extension.
Can I manage more than two resources?: Yes. Resources can be edited in the plugin settings. Use one line per resource in the format key|Display name.
What happens on uninstall?: Uninstalling the plugin removes its options and custom database tables, including stored booking requests and booking periods.
