Field initialization

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

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

    /**
     * Texts definition
     * @see the `Texts definition` section below
     */
    't_keyboard'   => 'Press the <kbd>CTRL</kbd> or <kbd>CMD</kbd> button to select more than one option.',
    't_no_options' => 'The field does no have any options.',
]);

// Multiple choice version
return \GetOlympus\Dionysos\Field\Select::build('my_multiselect_field_id', [
    'title'       => 'What are your preferred personas?',
    'default'     => ['minions', 'lapinscretins'],
    'description' => 'The White House needs your feedback asap!',
    'multiple'    => true,
    'options'     => [
        'minions'       => 'The Minions',
        'lapinscretins' => 'The Lapins Crétins',
        'marvel'        => 'All Marvel Superheroes',
        'franklin'      => 'Franklin (everything is possible)',
        'spongebob'     => 'Spongebob (nothing to say... Love it!)',
    ],

    /**

     * @see the `Texts definition` section below
     */
    't_keyboard'   => 'Press the <kbd>CTRL</kbd> or <kbd>CMD</kbd> button to select more than one option.',
    't_no_options' => 'The field does no have any options.',
]);

Variables definition

The variables definition depends on multiple value:

• set to false, a uniq string value is stored in Database
• set to true, an array of key values is stored in Database

In all cases:

Variable	Type	Default value if not set	Accepted values
title	String	'Radio button'	empty
description	String	empty	empty
options	Array	empty	Array with a key/value options

Uniq choice

Variable	Type	Default value if not set	Accepted values
default	String	empty string	One of the options keys
multiple	Boolean	false	nothing else

Multiple choices

Variable	Type	Default value if not set	Accepted values
default	String	empty array	Array with options keys
multiple	Boolean	true	nothing else

Texts definition

Code	Default value	Definition
t_keyboard	Press the CTRL or CMD button to select more than one option.	Used as a notice to help users to user multiselect field
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_select_field_id', '') or get_option('my_multiselect_field_id', []) (see WordPress reference):

// Get select from Database
$select = get_option('my_select_field_id', '');

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

// Get multiselect from Database
$multiselect = get_option('my_multiselect_field_id', []);

if (!empty($multiselect)) {
    echo '<p>And the nominees are:</p>';
    echo '<ul>';

    foreach ($multiselect as $value) {
        echo '<li>'.$value.'</li>'; // Will display key item options!
    }

    echo '</ul>';
}
