Field initialization

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

return \GetOlympus\Dionysos\Field\Radio::build('my_radio_field_id', [
    'title'       => 'Select a Minion that you may know',
    'default'     => 'kevin',
    'description' => 'A very important question! Pay attention to it ;)',
    'mode'        => 'default',
    'options'     => [
        'kevin' => 'Kevin',
        'mel'   => 'Mel',
        'dave'  => 'Dave',
        'bob'   => 'Bob',
    ],

    /**
     * Texts definition
     * @see the `Texts definition` section below
     */
    't_no_options' => 'The field does no have any options.',
]);

Variables definition

The display depends on the mode value:

• set to default (or inline), labels options will be displayed on the same line, as an inline-block display
• set to block, labels options will be displayed each per line, as a block display
• set to image, labels options will be displayed as default mode, with images and overlay text label
• set to image-block, labels options will be displayed as block mode, with images and overlay text label
• set to group, labels options will be displayed as a simple but efficient group of choices

Variable	Type	Default value if not set	Accepted values
title	String	'Radio button'	empty
default	String	empty string	One of the options keys
description	String	empty	empty
mode	String	default	see Variables definition
options	Array	empty	Array with a key/value options

Texts definition

Code	Default value	Definition
t_no_options	The field does no have any options.	Used as an error in the case no options have been set

Retrive data

Retrieve your value from Database with a simple get_option('my_radio_field_id', '') (see WordPress reference):

// Get radio from Database
$radio = get_option('my_radio_field_id', '');

// Display value
echo '<h2><b>'.$radio.'</b>, master of the ceremony</h2>';

Image mode

To display images instead of simple labels, set the mode to image and build the field's options as follow:

$options = [
    'key-name' => [
        'label' => 'Label item',
        'image' => 'https://label-image-url',
    ],
];

Below, a full example:

return \GetOlympus\Dionysos\Field\Radio::build('my_radio_field_id', [
    'title'       => 'Select a Minion that you may know',
    'default'     => 'dave',
    'description' => 'A very important question! Pay attention to it ;)',
    'mode'        => 'image',
    'options'     => [
        'kevin' => [
            'label' => 'Kevin',
            'image' => 'https://vignette.wikia.nocookie.net/despicableme/images/1/1d/Kevin_minions.png/revision/latest/scale-to-width-down/350?cb=20170703052012',
        ],
        'mel'   => [
            'label' => 'Mel',
            'image' => 'https://vignette.wikia.nocookie.net/despicableme/images/2/2e/Mel_Minion_01.png/revision/latest/scale-to-width-down/350?cb=20160717135212',
