## Description

Guests who found your apartment on Booking.com or Airbnb will happily book
 with
you directly, if you make it as easy as the portal does. That means a calendar they
can see, dates they can pick, and a button that starts the booking. Not a phone 
number and a hope.

This plugin puts exactly that on your WordPress site: the same availability
 calendar
and booking button your guests already see on your erphome.pl reservation page. 
Same apartment, same free dates, same prices, no commission taken out of the booking.

#### You need an erphome.pl account

This plugin is a bridge, not a booking system on its own. It displays a
 widget 
from an existing account on [erphome.pl](https://erphome.pl), a commission-free 
booking platform for apartment and vacation rental owners. If you do not have an
account yet, the plugin will show an empty settings page and nothing else.

What lives in erphome.pl (not in WordPress): apartment details and prices,
 reservations,
guest messages, payments, and calendar sync with the portals.

#### What the plugin adds to WordPress

 * **Shortcode** `[erphome_widget]`, which works anywhere shortcodes do:
    posts,
   pages, text widgets, page builders.
 * **Block** “ErpHome — Booking Widget”, with a live preview right in the
    editor
   and sidebar controls for apartment, language and size.
 * **Elementor element** “ErpHome — Booking Widget”, draggable straight onto
    the
   canvas with the same controls, so nobody has to hunt for the Shortcode element
   and type `[erphome_widget]` into it.
 * **Classic sidebar widget** for themes built around the Widgets screen.
 * **Settings page** (Settings  ErpHome) where you paste the link copied
    from your
   erphome.pl panel. The account and apartment slugs are read out of it automatically,
   so nobody has to explain what a “slug” is. Accounts with several apartments get
   a real dropdown, read from the account.

#### Fits the page instead of sitting in a box

The widget reports how tall it actually is, and the plugin sizes the frame to
 match.
No empty space underneath, and nothing cut off when the widget sits in a narrow 
column or on a phone. Turn it off in Settings  ErpHome if you would rather pin a
fixed height.

#### Tells search engines what your page is about

The widget is an iframe, and search engines do not read inside one. So a page
 with
only a widget on it says nothing about your apartment: no photos, no rooms, no ratings,
nothing for Google or an AI assistant to quote.

Switch on “Add apartment structured data” and the plugin publishes a
 schema.org**
VacationRental** block on your page, built from your erphome.pl listing: photos,
size, bedrooms and beds, amenities, check-in and check-out times, guest ratings 
and reviews, and your FAQ. It describes _your_ page and links back to your erphome.
pl listing as the same place, so the two do not compete.

It runs only on single posts and pages, and only where the widget is in the
 content,
never from a sidebar. It is off by default, so it can never surprise an SEO plugin
that already publishes this data.

#### Measurable

When a guest picks their dates and hits the booking button, the plugin pushes
 an`
erphome_booking_start` event into `dataLayer`, with the dates, number of nights 
and guest count. Pick it up in Google Tag Manager or GA4 and you will see how many
visitors actually start a booking, not just how many loaded the page.

#### Speaks your visitors’ language

The widget follows the language of your WordPress site, so an English site
 gets
an English widget and a Polish site gets a Polish one. Polish and English are both
built in.

Running a bilingual site? Set the language per embed:

    ```
    [erphome_widget lang="en"]
    ```

The same control sits in the block sidebar and in the classic widget. The
 apartment’s
own content (title, description) follows whichever languages you enabled for it 
in the erphome.pl panel, so an owner who translated the listing gets translated 
content here too.

#### Your calendars stay in one place

If your erphome.pl account syncs availability from Airbnb or Booking.com
 over iCal,
the widget shows that same combined, up-to-date availability. Sync is configured
once, in erphome.pl, and nothing about it needs repeating in WordPress.

#### Several apartments?

The `apt` attribute embeds a different apartment than the default one from
 Settings
ErpHome, so each apartment can have its own page:

    ```
    [erphome_widget apt="dom-nad-morzem"]
    ```

Available on the block and the sidebar widget too.

#### Why a plugin instead of pasting a script

The erphome.pl panel also gives you a `<script>` snippet for any website.
 On WordPress
that snippet has a habit of disappearing: the block editor strips `<script>` from
HTML blocks in some setups, caching and minification plugins defer external scripts
until the widget arrives late or not at all, and security plugins block third-party
scripts inside post content.

This plugin renders a plain `<iframe>` server-side instead. It has a known
 width
and height before the page paints, so nothing jumps around while loading, and there
is no external JavaScript for another plugin to break.

### External services

Everything below talks to one service: **erphome.pl**, specifically your
 account’s
subdomain `your-name.erphome.pl`, operated by ERP HOME Sp. z o.o. The plugin contacts
nothing else.

There are two separate connections, and they are worth telling apart.

**1. The visitor’s browser loads the widget (always).**
 The widget is an `<iframe
>` pointing at erphome.pl. On every page where you embed it (shortcode, block, or
sidebar widget), each visitor’s browser connects directly to erphome.pl to fetch
the current availability calendar. The address carries your account slug, optionally
the apartment slug, and a two-letter language code taken from your site’s language
setting (for example ?widget=1&lang=en). The plugin adds no visitor data to it.

If you switch on height fitting, the widget and the page also exchange
 postMessage
calls: the widget sends its content height and, when a guest presses the booking
button, the dates, night count and guest count they chose. That data stays in the
visitor’s browser. The plugin puts the booking-button event into `dataLayer`, where
your own analytics tools (if you use any) can read it. Nothing is sent anywhere 
by the plugin itself.

**2. Your server asks erphome.pl for your listing (only for two features).**
 When
you use the apartment dropdown, or switch on structured data, your WordPress server
calls the public erphome.pl API over HTTPS (`?api=apartments` and `?api=1`) to read
your own listing: title, description, photos, amenities, ratings and so on. This
is a plain GET with no authentication, it sends nothing about your visitors, and
the answer is cached for six hours. The same data is already public on your erphome.
pl booking page. Leave both features off and your server never contacts erphome.
pl at all.

## Blocks

This plugin provides 1 block.

 *   ErpHome — Booking Widget Embeds the ErpHome booking widget: an availability
   calendar and a link to book.

## Installation

 1. Install and activate the plugin.
 2. Go to Settings  ErpHome.
 3. Paste the “Widget preview” link copied from your erphome.pl panel (Settings  Calendars)
    and save. The account and apartment slug fields fill in automatically, and a live
    preview appears below the form.
 4. Add `[erphome_widget]` to a post or page, or insert the “ErpHome — Booking Widget”
    block in the editor.

## FAQ

### Do I need an erphome.pl account?

Yes. The plugin displays the widget from an existing account. It does not
 create
one, and it does not replace the erphome.pl panel.

### Is the widget available in English?

Yes. The widget follows your WordPress site language, with Polish and
 English built
in, and the `lang` attribute overrides it per embed. The erphome.pl panel and the
full reservation page are available in English as well.

### Does this work with my Airbnb or Booking.com calendar?

Yes, if your erphome.pl account already syncs availability from those
 platforms
over iCal. The widget always shows the same availability as your erphome.pl booking
page.

### Does it slow down my site?

No. The widget loads in a separate `<iframe>` with `loading="lazy"`, so it
 does
not block the rest of the page from rendering, and it adds no JavaScript or CSS 
to your theme.

### Where does the booking actually happen?

In the widget the guest picks dates and guest count and gets an instant
 answer 
on whether the dates are free. The button then opens your full erphome.pl reservation
page in a new tab, with those choices already filled in. The booking form, payments
and confirmation stay outside the iframe, which is what keeps payment gateways and
sessions working reliably.

### I have several apartments. Can I embed more than one?

Yes. Use the `apt` attribute on the shortcode, block or widget to pick a
 different
apartment than the plugin default on each page.

### Where do I find the link to paste into Settings  ErpHome?

In the erphome.pl panel: Settings  Calendars, section “Widget rezerwacji na
 Twoją
stronę”. Pasting the whole snippet works as well as pasting just the link.

### Can I change the size of the widget?

Width, yes: in Settings  ErpHome for the default, or per embed with the
 width attribute.
Height is normally handled for you, because the widget reports how tall it is. If
you switch that off, `height` applies as a fixed value: [erphome_widget width=”360″
height=”450″]

### Will the structured data clash with Yoast or Rank Math?

It should not. The plugin publishes one extra `VacationRental` block; SEO
 plugins
publish their own page and site markup and the two describe different things. If
your SEO plugin already publishes apartment or lodging data, leave this option off
rather than having two sources say the same thing.

### Does the plugin slow my site down by calling erphome.pl?

The dropdown and the structured data read your listing from erphome.pl and
 cache
it for six hours, so it is roughly four requests a day, from your server, not from
your visitors. A failed call is cached briefly too, so a temporary outage cannot
make every page wait. With both features off, your server never calls erphome.pl.

### How do I track bookings started from my site?

Switch on height fitting and the plugin pushes an `erphome_booking_start`
 event
to `dataLayer` when a guest presses the booking button, carrying erphome_apartment,`
erphome_check_in`, `erphome_check_out`, erphome_nights and `erphome_guests`. Add
a Google Tag Manager trigger on that event name.

## Changelog

#### 1.3.0

 * Elementor: the widget is now a draggable element with its own controls, instead
   of a shortcode you have to know about.
 * The height fitting now also covers widgets added to the page after it loaded (
   Elementor’s editor preview, page builders, popups, lazily loaded content).

#### 1.2.0

 * The widget now sizes itself to its content, so there is no empty space below 
   it and nothing gets cut off in narrow columns.
 * New option: publish schema.org VacationRental structured data for the apartment
   on your page, built from your erphome.pl listing. Off by default.
 * Accounts with several apartments get a dropdown in the settings and in the block,
   instead of typing the apartment slug by hand.
 * Pressing the booking button now pushes an `erphome_booking_start` event to `dataLayer`
   for Google Tag Manager and GA4.
 * The block sidebar is now translatable (JavaScript translations were missing until
   now, so those labels stayed English whatever the site language).
 * The block shows a preview in the inserter.

#### 1.1.0

 * The widget now follows the language of your WordPress site (Polish and English
   built in).
 * New “Widget language” setting, plus a `lang` attribute on the shortcode, block
   and sidebar widget for bilingual sites.
 * Fixed a layout overflow in the embedded widget at widths below roughly 420 px.
 * Fixed the settings page showing every notice twice.
 * Rewritten plugin description, added banner, icon and screenshots.

#### 1.0.0

 * Initial release: shortcode, Gutenberg block, sidebar widget, settings page with
   automatic link recognition.
