Usage

Request data from API

To implement an API request to your own plugin, use the (plugin_name)_set_api_endpoint filter to specify the endpoint (URL) to use when requesting data from an API.

Example from DTRT Forms:

Create the filter function:

    /**
     * Set the API endpoint
     *  The filter is applied in wpplugin->get_api_data()
     *
     * @return      string $endpoint
     *
     * @since       1.3.4
     *
     * @example
     *  add_filter( 'wpdtrt_forms_set_api_endpoint', [$this, 'filter_set_api_endpoint'] );
     */
    public function filter_set_api_endpoint() {
        $plugin_options = $this->get_plugin_options();
        $endpoint = '';

        if ( key_exists('value', $plugin_options['template']) ) {
            $template = $plugin_options['template']['value'];
            $endpoint = ( WPDTRT_FORMS_URL . 'data/form-' . $template . '.json' );
        }

        return $endpoint;
    }

Add the filter in wp_setup():

    protected function wp_setup() {
    	parent::wp_setup();

	// add actions and filters here
        add_filter( 'wpdtrt_forms_set_api_endpoint', [$this, 'filter_set_api_endpoint'] );
    }

Triggering a call to the API

API data is loaded via Ajax when the plugin settings are saved via the Settings page (assuming that an API key has been supplied in the provided form field).

Get saved data

$data = $this->get_plugin_data();

Data is stored in an associative array

Example response $data from API:

{
    "albumId": 1,
    "id": 1,
    "title": "accusamus beatae ad facilis cum similique qui sunt",
    "url": "http://placehold.it/600/92c952",
    "thumbnailUrl": "http://placehold.it/150/92c952"
}

$data as an associative array:

Array (
    'albumId' => 1
    'id' => 1
    'title' => 'accusamus beatae ad facilis cum similique qui sunt'
    'url' => 'http://placehold.it/600/92c952'
    'thumbnailUrl' => 'http://placehold.it/150/92c952'
)
