Field initialization

Use the following lines to add an background field in your WordPress admin pages or custom post type meta fields:

return \GetOlympus\Dionysos\Field\Background::build('my_background_field_id', [
    'title'       => 'Ooh, got ourselves an epic now...',
    'can_upload'  => false,
    'default'     => [
        'background-attachment' => 'initial',
        'background-color'      => 'transparent',
        'background-image'      => 'https://vignette.wikia.nocookie.net/despicableme/images/1/1d/Kevin_minions.png/revision/latest/scale-to-width-down/350?cb=20170703052012',
        'background-position'   => 'left top',
        'background-repeat'     => 'no-repeat',
        'background-size'       => 'cover',
        'height'                => '200px',
        'width'                 => '100px',
    ],
    'description' => 'Oh crap, I got knocked!',
    'size'        => 'thumbnail',

    /**
     * Settings definition
     * @see the `Settings definition` section below
     */
    'settings' => [],
]);

Retrive data

Retrieve your value from Database with a simple get_option('my_background_field_id', []) (see WordPress reference).
Below, a json_encode() example to understand how data are stored in Database:

{
  "background-attachment": "initial",
  "background-color": "transparent",
  "background-image": "https://vignette.wikia.nocookie.net/despicableme/images/1/1d/Kevin_minions.png/revision/latest/scale-to-width-down/350?cb=20170703052012",
  "background-position": "left top",
  "background-repeat": "no-repeat",
  "background-size": "cover",
  "height": "200px",
  "width": "100px"
}

And below, a simple example to show how to iterate on the data array in PHP:

// Get background from Database
$background = get_option('my_background_field_id', []);

// Check if background is empty and display it
if (!empty($background)) {
    $style = '';

    foreach ($background as $attr => $value) {
        $style .= $attr.':'.$value.';';
    }

    echo '<div style="'.$style.'">My content</div>';
}
