title: Creating a Plugin
---

import { FileTree, Steps, Badge } from "@astrojs/starlight/components";

In order to get started, you first need to
[setup your Castopod dev environment](https://code.castopod.org/adaures/castopod/-/blob/develop/CONTRIBUTING-DEV.md).

## 1. Create the plugin folder

You'll first need to create your [plugin folder](./#plugin-folder-structure) in
the `plugins/` directory.

### Using the create command <Badge text="Recommended" size="small" />

To quickly get you started, you can have a folder generated for you using the
following CLI command:

```sh
php spark plugins:create
```

👉 You will be prompted for metadata and hooks usage to have a skeleton plugin
project generated for you!

### Manual setup

<Steps>
  1. create a plugin folder inside a vendor directory

     <FileTree>
       * plugins
         * acme
           * **hello-world/**
         * …
     </FileTree>

  2. add a manifest.json file

     <FileTree>
       * hello-world
         * **manifest.json**
     </FileTree>

     See the [manifest reference](./manifest).

  3. add the Plugin.php class

     <FileTree>
       * hello-world
         * manifest.json
         * **Plugin.php**
     </FileTree>
</Steps>

## 2. Build your plugin

Now that your plugin folder is set, you can start working on your Plugin's logic
by implementing [the hooks](./hooks) needed.

### Settings forms

You can prompt users for data through settings forms.

These forms can be built declaratively using the
[settings attribute](./manifest#settings) in your manifest.

```json
// manifest.json
{
  "settings": {
    "general": {
      "field-key": {
        "type": "text",
        "label": "Enter a text"
      }
    },
    "podcast": {
      "field-key": {
        "type": "text",
        "label": "Enter a text for this podcast"
      }
    },
    "episode": {
      "field-key": {
        "type": "type",
        "label": "Enter a text for this episode"
      }
    }
  }
}
```

This example will generate settings forms at 3 levels:

* `general`: a general form to prompt data to be used by the plugin
* `podcast`: a form for each podcast to prompt for podcast specific data
* `episode`: a form for each episode to prompt for episode specific data

The data can then be accessed in the Plugin class methods via helper methods
taking in the field key:

```php
$this->getGeneralSetting('field-key');

$this->getPodcastSetting($podcast->id, 'field-key');

$this->getEpisodeSetting($episode->id, 'field-key');
```
