The radio field settings

Settings

Besides the common settings, this field has the following specific settings, the keys are for use with code:

Name	Key	Description
Choices	options	List of choices, each per line. If you need to set values and labels, use the format "value: Label" for each choice. When using with code, this setting is an array of 'value' => 'Label'.
Inline	inline	Display choices on a single line? true or false.

This is a sample field settings array when creating this field with code:

[
    'name'    => 'Radio',
    'id'      => 'radio',
    'type'    => 'radio',
    'inline'  => false,
    'options' => [
        'value1' => 'Label1',
        'value2' => 'Label2',
    ],
],

Data

This field saves a single selected value in the database.

If the field is cloneable, then the value is stored as a serialized array in a single row in the database.

caution

Note that this field stores the values, not labels.

Template usage

Displaying the selected value:

<?php $value = rwmb_meta( 'my_field_id' ); ?>
<p>Selected: <?= $value ?></p>

Displaying the selected label:

<p>My choice: <?php rwmb_the_value( 'my_field_id' ) ?></p>

Displaying both value and label:

<?php
$field   = rwmb_get_field_settings( 'my_field_id' );
$options = $field['options'];
$value   = rwmb_meta( 'my_field_id' );
?>

Value: <?= $value ?><br>
Label: <?= $options[ $value ] ?>
