Utilise API endpoints for your Select Fieldtype options.

API Select requires a license.

You can purchase one at https://statamic.com/marketplace/addons/api-select

You may use API Select without a license while Statamic is in Trial mode.

Require it using Composer.

composer require laraluke/statamic-api-select

Publish the assets:

php artisan vendor:publish --provider="Laraluke\ApiSelectFieldtype\ServiceProvider"

Add the fieldtype to your fieldset/blueprint. You will then need to configure the following settings:

This is to define whether or not your endpoint value is a URL or a config variable.

If your endpoint type is a URL your endpoint value will look like this:

https://jsonplaceholder.typicode.com/users

If your endpoint type is a config variable your endpoint value will look like this:

endpoints.users

and your endpoints.php file would look something like this:

return [
    'users' => 'https://jsonplaceholder.typicode.com/users',
];

This is how long API requests will be cached for in minutes.

Set this value to 0 if you don't want to cache results.

If your data set isn't in the top-level of your API response you can define it's location using dot syntax.

So if your API result looks like:

{
    "data": {
        "users": []
    }
}

You would set the data set key value to:

data.users

Define the unique identifier to be used as the option value.

So if the iteration in your API result looks like this:

{
    "id": 1,
    "name": "Leanne Graham",
    "username": "Bret",
    "email": "Sincere@april.biz",
}

You might set your item key to:

id

Define the value to be used as the option label.

So if the iteration in your API result looks like this:

{
    "id": 1,
    "name": "Leanne Graham",
    "username": "Bret",
    "email": "Sincere@april.biz",
}

You might set your item label to:

name

Let's assume your API select field handle is api_select_users API response is like so:

[
    {
        "id": 1,
        "name": "Leanne Graham",
        "username": "Bret",
        "email": "Sincere@april.biz",
    },
    {
        "id": 2,
        "name": "Ervin Howell",
        "username": "Antonette",
        "email": "Shanna@melissa.tv",
    }
]

{{ api_select_users.name }}

// Returns
Leanne Graham

{{ api_select_multi }}
    {{ name }}
{{ /api_select_multi }}

// Returns
Leanne Graham
