## Опис

This plugin registers **f.upcellia.com** as an oEmbed provider in WordPress. Paste
a public Upcellia form URL into the **Embed** block to display the form in posts,
pages, and previews.

**Features**

 * Registers the oEmbed provider with `wp_oembed_add_provider()`
 * Works with the generic Gutenberg Embed block
 * Clears stale oEmbed caches when saving posts
 * No settings screen: activate and embed
 * Full-width embed styles on the frontend

**Requirements**

 * Forms published on [Upcellia](https://upcellia.com)
 * Public URL format: `https://f.upcellia.com/{code}`

**Usage**

 1. Activate the plugin.
 2. In the editor, add an **Embed** block.
 3. Paste your form URL, for example:
     https://f.upcellia.com/St4xnF?utm_source=web&
    utm_medium=website
 4. Save the post and check the preview.

## Встановлення

#### Automatic installation

 1. Go to **Plugins > Add New** in WordPress.
 2. Search for **Upcellia Forms oEmbed**.
 3. Click **Install Now**, then **Activate**.

#### Manual installation

 1. Download the plugin ZIP file.
 2. Go to **Plugins > Add New > Upload Plugin**.
 3. Select the ZIP and activate the plugin.

#### Must-Use (optional)

To force-load on multisite or controlled environments, copy `upcellia-forms-oembed.
php` to `wp-content/mu-plugins/`.

## Часті питання

### The editor shows the form but the preview only shows a link

Save the post again (Update or Publish). WordPress caches oEmbed responses on save.
If the first attempt failed, the preview may show only the URL until the cache is
refreshed.

### Do I need to configure anything?

No. The plugin only registers the Upcellia oEmbed endpoint. Forms are created and
published from the Upcellia admin panel.

### Does it work without this plugin?

WordPress may discover oEmbed via metadata on `f.upcellia.com`, but this plugin 
improves reliability in PHP previews and on the frontend.

### Can I use an iframe instead of oEmbed?

Yes. In Upcellia, open **Get embed code** in the form builder and use the **Custom
HTML** block with the iframe code.
